Sanitary Ball Valve Overview

Posted on by

The sanitary ball valve is a valve with a spherical disc, the part of the valve which controls the flow through it. The sphere has a hole, or port, through the middle so that when the port is in line with both ends of the valve, flow will occur. When the valve is closed, the hole is perpendicular to the ends of the valve, and flow is blocked.  The handle or lever will be in line with the port position letting you see the valve’s position. The ball valve along with the butterfly valve and plug valve, are part of the family of quarter turn valves.

 

Using ball valves in sanitary applications has some pluses and minuses. Perhaps the greatest benefit of using sanitary ball valves is that they usually work to achieve perfect shutoff even after years of disuse. They are therefore an excellent choice for shutoff applications and are often preferred to sanitary butterfly valves, diaphragm valves or seat valves. They do not offer the fine control that may be necessary in throttling applications but are sometimes used for this purpose. The other big advantage ball valves have is that they are the highest pressure rated sanitary valves on the market.

 

Principles of Operation

 

Sanitary ball valves, as the name implies, have a ball with a hole drilled through the center swivel mounted with the valve body. When the hole in the ball is oriented in the same direction as the pipe, this will result in full flow rate. As the hole in the ball is oriented away from the direction of the pipe, the flow rate will be restricted and finally cut off completely when the hole is oriented 90 degrees to the pipe direction.

 

Automation

 

Like sanitary butterfly valves, most sanitary ball valves can be highly automated.  Ball valves are offered with stainless steel actuators for all sizes.  There are different switch packages available which to mount to the actuators. Double rack and pinion pneumatic actuators are the standard for ball valves, because they are ¼ turn valves.  Also the same as the butterfly valves, ball valves have a large offering of different ¼ turn actuators on the market.

 

Other Features and Benefits

 

Many different manufacturers offer their version of a ball valve although the operational features are very similar. In the market of ball valves there are many different alternative choices so that potential customers are easily able to find another choice. For this reason it is important to decipher a customer’s needs for the application at hand. This will make it possible to choose the one that will be a quality performer at a good price.

 

Like the butterfly valve, a ball valve is available in 316 as well as AL6XN and Titianium material. This type of construction material is not available with all manufacturers, as well as, it can be difficult to find MTRs and C of C’s to go along with the desired valve.  There are multiple handle styles that are offered with the ball valve as well, such as, pull stop with a locking mechanism and trigger handles. Ball valves have the luxury of coming with many different connection styles in order to be able to fit into a customized sanitation process line.

 

Are Sanitary Ball Valves Really Clean?

 

As we discussed with the butterfly valve. What is considered “sanitary” is relative to each end user. The fact that sanitary ball valves are constructed of 316 stainless steel, have FDA approved elastomers and have Tri-clamp or tube OD butt weld ends puts them in the sanitary realm. But you really cannot truly clean it in place. Ball valves have cavities and crevices behind the ball that gather product when the valve in being actuated. These areas do not get clean during CIP. To truly clean the valve, you have to take it apart.  Even with newer designs of ball valves having FDA approved cavity fillers to help limit product build up on the inside of the vale it is inevitable that product will still accumulate around the outside of the ball and orifices. Because of the sanitary ball valve do not carry the 3A rating.

 

TARGET VALVE is the professional valves manufacturer in Taiwan. You can find a variety of valve products on their website. Such as 1 pc ball valve, economic ball valves, flanged ball valves, multiway ball valves, and sanitary ball valves etc. Learn more details, welcome to check out their website and feel free to contact them directly.

Pull Studs: Importance of Selection and Maintenance

Posted on by

Pull stud is the tension part between the principal spindle of the boring milling CNC machine tool and the tool holder. It is also called pull head, connecting pull head, thread pull head, tool holder pull head, tool holder pull stud, tool holder joint, fastening pull stud and tool holder tensioner, etc. Due to its small volume and low value, its importance in work is easily neglected by people. To better develop the role of the lathe, it is necessary to have a understanding about the pull stud and lathe tension mechanism.

 

Pull Stud Stand and Its Combination:

 

Pull Stud Is The Spare Part Fixed At The Tail End Of Various Tool Holders Through Thread.

 

The tension mechanism inside the principle spindle of the lathe tensions the tool holder in the principal spindle by use of it. The tensioning is maintained by replying on a group of springs. After tension is realized, the prolapse of tool holder and tool from the high-speed rotary principal shaft can be avoided sufficiently.

 

Pull stud is designed according to the standards of tool holder and related part of the lather. Due to the various standards for the tool holder, the lather tension mechanism also differs. Therefore, the united standards cannot be formed for the pull studs. Sometimes, the two ends of the pull studs live up to certain standard (like ANSI, DIN, ISO or JMTBA). However, sometimes, the mixture form (the thread part is adapted to the tool holder part of ISO standard while the pull stud head is also adapted to the lather of ANSI. In this case, such mixture combination can bring about a lot of different pull studs) also exist. In case of inappropriate selection of pull studs, the accident will be caused when using the tool holder after it is installed in the tool holder.

 

Selection of Pull Stud:

 

Facing Various Pull Studs, How to Find Out The Specification And Type You Need?

 

It is better to select the pull studs according to the instruction of the lather. The drawing or type of the pull stud will be given out in the instructions of lather by most lather manufacturer. Additionally, the determination can be made after measuring the pull studs for the lather. Most pull studs are of 10-12 dimensions. It is necessary to provide the details to the supplier in case of ordering. However, the attentions should be especially paid to main three parts: namely the angle of pull stud, the distance from the base level to this angle and the thread type. These three dimensions are easily measured. If a national lather (Actually, the taper hole of the principal spindle is British system dimension, it is just labeled by changing it into the metric unit) and a batch of tool holders of British system taper are bought for a workshop. As for the pull studs, the thread is labeled with America system (adapted to the tool holder), the metric system shall be used for other dimensions and adapted to tension mechanism of lathe.

 

If you are looking for pull studs manufacturer, Shin-Yain Industrial Co., Ltd. is a wonderful choice! This company is a well-known tool holders manufacturing expert in Taiwan. Shin-Yain can offer a variety of tool holders, collet chucks, pull studs, and shrink fits to you. More details, try to check out Shin-Yain’s website: www.syic.com to gain you need.

When to Use Swing Check vs Wafer Check Valve

Posted on by

When it comes to check valves, swing checks and wafer checks are actually similar in many ways. Both serve to block back flow from occurring in a pipe line. Both use a swinging disc to block and allow flow in one direction. The differences in the two valves may seem obvious when you look at them, but many users don’t realize the difference it might make in their application.

 

Wafer check valves get their name from their wafer thin design. These valves are sleek and made to fit in tight spaces between two flanges. There are no controls on this valve. The main component of the valve is a swinging disc in the center that opens in one direction and closes if liquids flow back the other direction.

 

Swing check valves, as the name implies, also uses a swinging disc to allow or block flow. The difference between the two is in the body design. Swing check valves are not designed for extremely tight spaces like the wafer check. They have molded bodies around the area where the disc opens up. This is the most important difference between the two types of valve.

 

While at first glance this may just seem like a space issue, the presence of a valve body as opposed to the bare bones wafer check actually makes a big difference in the functionality of the valve. Because wafer check valves are flanged in place, there isn’t much room for the disc to open in the pipe line. That means flow is often restricted with a wafer check valve.

 

Swing check valves on the other hand, have a molded body that creates room for the disc to swing open fully, thus allowing full flow. As you can imagine, this is immensely important if your application requires full flow. For this reason, we recommend wafer check valves for applications where flow is not an issue, and swing check valves when a full port valve is required.

 

You can easily find a reputed and well-known provider of these different types of valves on the internet such as the NICO VALVES CORP. This company always offers the best quality wafer check valves and other valves to you. Learn more information about valves, try to check out NICO’s website here: www.ni-co.com

When Is Ultrasonic Polishing Equipment Justified?

Posted on by

Ultrasonic polishing is ideal and justifiable when work on small to very small details is required.

 

Manual polishing is a very tedious process, and in particular very small intricate detail work requires additional effort and patience. Ultrasonic lapping machines, available now for quite some time, have been improved in recent years to effectively replace certain time-consuming and costly small detail hand finishing work.

 

Ultrasonic Unit Features

By comparison to conventional die profilers, as well as air-powered lapping machines that may have a stroke length of up to ¼ inch, the reciprocating action of an ultrasonic unit ranges only from .00004 to .00012 inches. However, the extremely fast reciprocating tool motion of 21,000 and up to 25,000 strokes per second provides the extra productivity and gives the polisher complete fingertip control when finishing even the most intricate ridges, slots and details.

 

Ultrasonic systems usually consist of an electronic power module (110 or 220 volt) with a slender electric cord that powers the lightweight and easy to manipulate small, ultrasonic handpiece. Commonly, an automatic power feed system in the module adjusts the frequency required to accommodate the various individual abrasive tools that are installed for the finishing process. The systems are equipped with numerous clamps that will accommodate tools ranging from small diamond files to conventional type polishing stones and/or ceramic stones and laps.

 

As with all other power tools, great care and attention should be given when working with ultrasonic machines. Because of the ultra-fast motion, tools that are overly aggressive (especially coarse diamond files, etc.) should never be used. Surfaces that must be flawless can easily be scratched and made wavy or damaged.

 

On the other hand, dense/hard, fine grit ceramic or vitrified abrasive polishing stones or laps made of brass and cast iron when used with premium diamond compound, permit the beginner to acquire a better understanding of the fast cutting powers these ultrasonic systems offer. Note: Only the most experienced operator should use diamond files or diamond stones for ultrasonic polishing.

 

Ultrasonic Applications

We need to stay objective and remind ourselves that ultrasonic polishing is not for everyone. Frequently, ultrasonic systems are perceived to take care of all polishing problems. This is not so. Ultrasonic polishing is not a cure-all for every mold and die shop that does in-house polishing. There are many polishing professionals and/or mold shops—doing mostly mid-size to large work—that may not require an ultrasonic system. In many instances, the units are simply not practical for mid-size to large type work and ultrasonic systems are not recommended to be used on larger details and surfaces exceeding a 3/8-inch square.

 

Nevertheless, ultrasonic finishing has its place in a polishing environment and it is not overstated to say that in some instances the cost of one ultrasonic system may be recouped by polishing three to four multiple cavity/core molds. For instance, an experienced individual, when working with an ultrasonic polishing machine on very small details, may reduce finishing time by as much as 40 percent and up to 65 percent.

 

In the past, there have been several good, but very expensive ultrasonic systems on the market. The name of one system may differ from the other, yet they all practically evolved from one source. However, several new models, which have been recently developed and have proved to be highly effective, as well as very affordable for even the smallest mold shop or polishing house, are now available in the marketplace.

 

Ultrasonic Advantages

Ultrasonic units with super-fast, very short strokes, provide virtual unrestricted fingertip control. By comparison, regular reciprocating tools—such as air-driven or electric flexible shaft-operated die profilers—are more restrictive in movement and less flexible to handle.

 

Nevertheless, die profilers and/or various other filing machines are great for medium to large mold details and when used at a comfortable speed range and proper stroke lengths they will provide excellent finishing capabilities.

 

Ultrasonic polishing is ideal and justifiable when work on small to very small details is required. It is safe to say that the smaller, more intricate or precise the finishing work needs to be, and/or the harder the materials are which require finishing, the more likely it is that an ultrasonic unit will improve polishing time. Subsequently, complicated heat-treated molds and dies, carbide dies or inserts and detailed punches with fine edges and very narrow slots machined by EDM are perfect for using ultrasonic polishing systems.

 

It should be mentioned here that there are other advantages that make certain ultrasonic systems a practical purchase. Meaning, various models offer dual operating capabilities where the electronic power module not only has the ability to drive the ultrasonic handpiece, but also regulate the speed and rotational direction for a variety of rotary and/or reciprocating hand tools. Having these secondary functions presents additional cost savings over single function ultrasonic units as they permit a full range of filing/reciprocating capabilities as well as rotational grinding/polishing using mounted points, burs, polishing brushes and felt bobs. Furthermore, since the rotary or reciprocating hand tools are powered with internal DC motors, the thin electrical cord provides more freedom of movement when compared to flexible shaft powered tools.

 

Summary

When selecting a supplier for this type of equipment it is most prudent to purchase from a respectable company that has been around for many years, offers good customer service and has some experience in ultrasonic polishing, which can be passed on to the customer, even via the telephone.

 

I think Best Diamond Industrial Co., Ltd. will be the most excellent choice. Besdia supplies high quality ultrasonic lapping machine and much more tools for you. Learn more information about Besida, welcome to check out the website here: www.besdia.com

Beginners Guide To The Impact Wrench

Posted on by

If you’ve ever experienced trying to loosen a large, fretted or corroded fixing, then you’ll appreciate what I’m about to say. Often working in tight spaces or at awkward angles, nuts and bolts can be extremely difficult and time consuming to fit or remove. Skinned knuckles, broken tools and jobs taking hours longer than you’d planned, all contribute to the frustration that nuts and bolts cause on a daily basis for people across the world. Even experienced professionals, such as fitters and mechanics, will experience these problems on a regular basis.

 

The solution? Well, there are a number of factors to consider, but the most important is the force you apply to the fixing. Without adequate force, the fixing will either be under tightened (under torqued) or simply won’t come undone. Secondly, and this is particularly important for busy professionals, the time taken to fit or remove a fixing can be painstakingly long if it is in a hard to reach position. Similarly, the time taken up by repetitive jobs, like removing and refitting vehicle wheels, can really add up over the course of a day and eat into your profit margin or your family’s patience.

 

Using an impact wrench solves both these problems. It is capable of delivering a much larger force than you can apply by hand, without additional leverage, and it greatly speeds up the tightening and loosening of fixings, especially those that are hard to reach. So, if you can relate to what I said earlier, you’ll want to read on.

 

What Is An Impact Wrench And How Does It Work?

An impact wrench is used to aid the tightening and loosening of nuts and bolts by reducing the effort required by the user and increasing the speed at which fixings can be tightened or loosened. There are a variety of different types on the market but they all work in fundamentally the same way. Essentially, they apply a rotational force (or torque) in short bursts (or impacts). They are driven by a motor which is powered by air, mains electricity, or battery (usually referred to as a “cordless impact wrench”).

 

Because the force is applied in short bursts, the user is able to apply a much larger torque to the fixing than they would use a regular wrench; sometimes with only one hand. This greatly reduces the effort required by the user, which results in less fatigue and fewer injuries or strains. The time required to complete a task is also reduced meaning that the user can finish the job faster and, in the case of a business, generate greater revenue and profit.

 

Which Type Is Right For Me?

Of the 3 different types of impact wrench, air, electric and cordless, each has its advantages over the others. Originally, only the air impact wrench was available and used mainly by professional and race mechanics to quickly remove and refit wheel nuts (lug nuts). Depending on the model, air tools are powerful, fast and robust making them ideal for use in a professional environment. However, they do require a large volume, high pressure air supply to operate and regular maintenance, which means they aren’t really suitable for infrequent or home use. And, as they’re attached to the compressed air supply by an airline, it can be difficult to move them around a workspace.

 

The corded electric impact wrench is also powerful and fast (again, depending on the model) but is less robust than the equivalent air tool. It too is attached by a cord making it difficult to move around a workspace and, of course, it cannot be used in the absence of a mains electricity supply. However, it can be less expensive than an air or cordless impact wrench, making it an attractive choice for home use.

 

Perhaps the most sought after, particularly in recent years as the technology has improved, and are cordless (battery powered) impact wrenches. The more expensive, higher voltage units deliver performance approaching that of an equivalent air tool but without the additional infrastructure. They are also completely portable and the absence of a cord means they can be moved easily around a workspace and used in hard to access areas. Unfortunately, they are often the most expensive and can be relatively heavy due to the weight of the battery packs.

 

At present, air impact wrenches remain the most popular with professional mechanics. But, as technology continues to improve, the cordless impact wrench will become increasingly popular, less expensive, and ultimately dominate the market.

The Advantages of Shrink Fit Chuck

Posted on by

If you do high speed, or high torque machining you should seriously consider the benefits of shrink fit technology.

 

Heat shrink tooling is considered one of the best methods for high-performance machining. The mold and die industry was the first segment of the manufacturing market to look for more precise tool holder options, due to the need for a slim nose and long reach. Today, every segment of manufacturing can benefit from the advantages of shrink fit tooling.

 

In this article, I’m going to show you the basic introduction to shrink fit chuck.

 

Tool holder Selection

 

When looking for tool holder solutions for any type of machining, it is always good to focus on the three main features that a tool holder must bring you:

 

  1. Rigidity

Rigidity comes from sufficient taper contact and proper clamping of the tool holder in the machine tool spindle.

 

  1. Accuracy

Accuracy comes from minimal run-out at the cutting edge of the cutting tool when clamped in the holder.

 

  1. Balance

Balance comes from a balanced assembly of the tool holder (including all accessories such as pull-studs) and cutting tool combination.

 

You may also often think about the following:

 

  • Geometry of Tool Holder

Geometry is important to avoid collisions with the workpiece. In regards to the EDM process, electrodes must be machined accurately and efficiently. Oftentimes, deep ribs are required in the part process and may present challenges. Also, deep cavities such as large door panel or bumper molds require deep reach with extreme clearances.

 

  • Cleanliness of The Tool Holder

Cleanliness is required to avoid excessive run-out, especially when machining graphite.

 

  • Extending Cutting Tool Life

Since high-end cutting tools are needed to obtain the best performance in the shortest time possible, a tool holder that extends cutting tool life can be advantageous. These cutting tools often have exotic coatings that lend to an expensive price.

 

  • Surface Finish at Higher Speeds and Feeds

Some tool holders are used with lower depth-of-cuts, which translates into better surface finishes. This makes balance even more important to minimize vibration at the cutting edge of the cutting tool. Also, proper chip evacuation provides better finishes.

 

Advantages of Shrink Fit Chuck

 

There are 10 inherent benefits that a good shrink fit chuck can offer:

 

  1. Unsurpassed Accuracy

A properly produced shrink fit chuck should be able to guarantee 0.00012’’ (3 microns) maximum run-out at three times the cutting tool diameter.

 

  1. Availability of Slim Profiles

Shrink fit chucks are available with three-degree draft angles and very slim profiles. They can also be modified to be straight walled, if needed, in order to prevent tool holder collision with the workpiece.

 

  1. Gripping Torque

A shrink fit chuck grips the cutting tool 360 degrees around the shank. This leads to a very high gripping torque that prevents the cutting tool from moving during roughing or finishing operations.

 

  1. Extended Reach Options

Shrink fit chucks can use shrink fit extensions that provide the user with many options with standard products. When machining deep cavities, one can place shrink fit extensions into standard shrink fit chucks, getting unsurpassed tool holder lengths with very little run-out.

 

  1. Balance Repeatability and Balanceable Options

Shrink fit chucks can offer some of the best balance repeatability of any tool holding system on the market, since there are no moving parts. In many cases, if a shop purchases a properly balanced shrink fit chuck with correct accessories (such as pull-studs) and uses good cutting tools without inherent unbalance (such as flats or unequal spacing), then they can often have good balance characteristics for running at high speeds without doing an additional fine-tune balancing.

 

  1. Reduction of Tool Changing Time and Less Tool Holder Accessory Inventory

Nothing beats the tool change time of shrink fit chucks if the process is joined with a capable inductive shrink fit machine. Tool changes can be done in 5 to 10 seconds, and most importantly, consistently. This allows the tool holder assembly to be in the machine making chips more of the time, rather than out of the machine waiting to be changed. Also, a shop needs very little additional tool holder accessory inventory (i.e., collets, nuts, seal disks, etc.). This simplifies the process.

 

  1. Cleanliness of Setup

A shrink fit chuck typically is a sealed system by design. Therefore, the introduction of contaminants in the bore is minimized. If contaminants are introduced to the bore of a tool holder, oftentimes run-out accuracy is compromised.

 

  1. Coolant Options

Shrink fit chucks have convenient methods to deliver coolant down to the cutting edge of the cutting tool. This helps with the proper removal of chips and can also aid in providing better finishes.

 

  1. Consistency of Setup

Shrink fit holders provide the great repeatability from tool holder setup to tool holder setup. This is especially beneficial for those shops running lights out. For example, all tool holder setup operators set the tool holders the same with shrink fit holders. There are no variables—such as over-tightening or under-tightening a collet nut or not cleaning out a chuck sufficiently.

 

  1. Availability of Shrink Chucks

Most of the major tool holder builders in the world now offer shrink fit chucks as a standard.

 

If you have any question about shrink fit tooling, I recommend that you can visit SYIC’s website and feel free to send inquiry to them. SYIC is the company of specializing in shrink fits, tool holders, and milling chucks etc. Learn more details about their products, try to check out their product pages!

Tips to Help with Choosing the Right Valve for Your Project

Posted on by

Valves are useful pieces of equipment that help control, limit, and shut off flow in a system. In a garden irrigation system, you could use valves to control when different plants get watered. While it is universally agreed that valves are helpful, choosing the right valve can be frustrating. We hear many customers make statements like these: “So many types exist! Some of them do similar things! I don’t know what types of valves to use!”

 

In this article, we will outline what makes each unique valve. For basic users, the most important thing to remember is that a valve does one of two things: shut off or regulate. Some valves can do either/both, but this is a simple way to think of what you need a valve to do. It could help you in picking the right valve. We will now cover each of the major valve categories.

 

Ball Valves

Ball valves are a good example of a shut off valve. They use a spherical seating to stop or allow flow. The ball has a hole through the center, so fluid can pass through when the handle is turned to the “on” position. When the handle is turned 90 degrees to the “off” position, fluid hits the solid side of the ball and is stopped.

 

Butterfly Valves

Butterfly valves can function as a shut off valve or as a regulatory valve. They can fully shut off flow or be kept partially open, which limits flow. Controlling flow can be extremely helpful if you want to decrease pressure in a system. Fluid passing through a small opening will be restricted, making pressure further down the pipeline lower, depending on how far open the valve is. Butterfly valves can also be used as typical 90-degree turn valves, just switching between “on” and “off” positions.

 

Gate Valves

Gate valves, while usually used as shut off valves, can also function as regulatory valves. They use a “gate” that drops or lifts to control flow. When the valve is open, the gate is stored in the tall upper section of the valve, which is where gate valves get their unique shape. Unlike the previous two valves, gate valves are not a quarter-turn valve. They use a hand wheel to open/close whereas ball and butterfly valves use a lever handle. This makes it easy to keep them partially open and also makes operation of any kind easier.

 

Check Valves

Check valves come in many forms. The primary function of check valves is to prevent backflow. This makes them regulatory valves, as they control flow direction. Check valves are controlled by the fluid in the pipeline instead an operator, which makes them different from the valves we have previously examined. Check valves come in many different forms, but we will just cover the two most common types.

 

Swing check valves are a type of valve that uses a swinging function to prevent backflow in a system. The clear PVC swing check valve to the right has a disc that swings open if fluid is passing through the desired direction. If anything tries to flow backwards, the disc is pushed closed, stopping flow. Swing check valves create minimal pressure drop, as the disc is pushed completely out of the way when in operation.

 

The other major type of check valve is the ball check valve. Ball check valves use a ball or half-ball seating to eliminate backflow. When fluid passes the desired direction, it hits the rounded side and passes around and through. If fluid tries to flow backwards, it hits the concave side of the half-ball, pushing the valve shut. Due to the fact that fluid must flow around and behind the ball to get through, ball check valves produce moderate pressure drop.

 

Diaphragm Valves

Diaphragm valves, while not one of the most common types of valves, are very interesting and serve a specific purpose. They are perfect for limiting pressure in a system, making them regulatory valves. These valves have a flexible diaphragm that lowers toward or rises from a “weir” or “saddle” seating. The effect is that only a limited amount of fluid is allowed to pass through.

 

Choosing the Right Valve

In the end, picking the right valve depends on what you need it to do. No two jobs are the same, so there is no one-size-fits-all valve solution. However, you should now have all the information you need to make an informed decision.

 

NICO VALVES CORP. is a leading industrial valve manufacturer in Taiwan and China. The company offers various valves such as check valve, ball valve, threaded end valve, wafer check valve etc. If you have any questions, try to check out NICO’s website and feel free to send inquiry to them.

Gear Rack and Pinion in Straight Cut and Helical

Posted on by

Tell you some information about precision rack and pinion in this article.

 

Rack and Pinion

 

Rack and Pinion assemblies are utilized to convert rotating movement into linear motion. A gear rack has straight teeth cut into one surface of a square or round section rod with a pinion, which is a small cylindrical gear meshing with the gear rack.

 

There are applications where the gear rack is stationary, while the pinion traverses and others where the pinion rotates on a fixed axis while the gear rack moves. The former is used widely in conveying systems while the latter can be used in extrusion systems and lifting/lowering applications.

 

As a mechanical element to transfer rotary into linear motion, gear racks are often compared to ball screws. There are pros and cons. The advantages of a gear rack are its mechanical simplicity, large load carrying capacity, no limit to the length, etc. One disadvantage though is the backlash. The advantage of a ball screw is the high precision and lower backlash while the shortcomings include the limit in length due to deflection.

 

Types of Gear Rack

Rack and pinion gears are available in two variations:

 

Straight teeth have the tooth axis parallel to the axis of rotation. Straight teeth that run parallel to the axis of the gear.

 

Helical teeth gears provide continuous engagement along the tooth length and are often quieter and more efficient than straight tooth gears and also offer higher loading for same rack width. Helical tooth gears resemble spur gears in the plane of rotation, but include teeth that are twisted along a helical path in the axial direction.

 

Applications of Rack and Pinion

 

Rack and Pinion drives are perfect for a wide range of applications, including axis drives requiring precise positioning & repeatability, travelling gantries & columns, pick & place robots, CNC routers and material handling systems. Heavy load capacities and duty cycles can also be easily handled with these drives. Industries served include Material Handling, Automation, Automotive, Aerospace, Machine Tool and Robotics.

 

JIA CHENG Precision Machinery Co., Ltd. reducer is a worldwide well-known brand. This company also provides high quality couplings, gear row, precision rack, and much more products for customers.

Simple Introduction of Butt Weld Fitting and Where to Find The Best One?

Posted on by

Have you ever heard or seen the butt weld fitting? If you haven’t, that’s OK. I will have a simple introduction for you. Let us learn some information about butt weld pipe fitting below:

 

What is A Butt Weld Pipe Fitting?

Wellgrow Butt Weld Fittings
A butt weld pipe fitting is designed to be welded on site at its end(s) to connect pipe(s) together and allow change in direction or pipe diameter, or branching or ending.

 

This fitting then becomes part of a system for transporting fluids (oil, gas, steam, chemicals, etc.) in a safe and efficient manner, over short or long distances.

 

Other types of fittings can be threaded or socket welded.

 

What is The Application of Butt Weld Fitting?

 

Butt weld fitting keeps better strength, good for high pressure or high temperature pipelines. So it is used when a welded joint with strength not lower than that of the base metal itself is needed.

 

The Feature of Butt Weld

 

Butt weld is the “best” in terms of strength, fatigue, and corrosion resistance, and temperatures compliance. However, it is more difficult to fit-up and weld properly, needing skilled welder and much time.

 

Where to Find The Best Butt Weld Fittings Manufacturer?

 

When mentioned the stainless fittings manufacturer, I will think of Wellgrow Industries Corp.

The report titled “Global Hydraulic Cylinder Market 2016-2020” was released by Research and Marketsand focuses on the current state of the market and the growth prospects of the global hydraulic cylinder market for 2016-2020.

 

According to the report, one of the primary drivers in the market is raising demand for food and fiber to drive agriculture industry. The burst in population figures suggests that by 2050 the population will expand up to nine billion. In order to cater to the growing food requirements to sustain such a large population, the agriculture industry will need sophisticated equipment to carry out effective agricultural processes; the agriculture industry will grow at 3.61% CAGR annually. The mechanization of agricultural processes will help increase the sale of agricultural hydraulic cylinders.

 

To calculate the market size, the report discusses major drivers that are influencing market growth and challenges faced by vendors and the market as a whole.

 

One of latest trends in the market is raising popularity of integrated solution and services. The report says: “Vendors are more focused on providing integrated solutions to its customers. They offer both the product (hydraulic cylinders’ system) and solutions to differentiate themselves from other market vendors.

 

“Integrated solutions help achieve profitable maintenance and aftermarket service revenue. This also strengthens the vendor-client relation. In an integrated system, all components of a hydraulic system such as hydraulic cylinder, valve, and pump are sold as a single unit or kit. For end-users, this solution helps reduce the time frame of procurement. Clients react favorably to solutions that offer better outcome with enhanced performance. These systems provide users with efficiency, engineering, and purchase solution. This lowers the overall operational cost and lead times.”
