Ball Valve History & Mystery

Posted on by

Here is a light hearted history and trivia on the ball valves. Read it and you will never take your natural gas or electricity for granted again, OK so maybe you will…

Ball Valve mystery?

The humble ball valve has a checkered history and somewhat murky origins. It may not be cloak and dagger stuff, but it’s not without mystery… Take a look around to see where the ball valve is indispensable. For example, the ball valves are crucial to the petroleum industry, water, electric power, chemical, paper, pharmaceuticals, food, steel and other fields. If it seems we could not get a long without the ball valve, it’s probably true! Given the importance of the ball valve today, it’s a mystery why it took so long to invent.

Ball Valve history does not go back to ancient Greece or the American Revolution nor does it? The modern ball vale was invented in 1967 or about 1957 according to different sources. Who cares when the ball valve was invented? Besides the patented owner, probably not many people. Still the ball valve was major advancement over plug valves used in the 20th century. The earliest ball valves were commercially available around 1967. For ancient parallels, the ruins of Pompeii turned up a bronze tapered plug quarter turn valve that resembles to the ball valve today. How’s that for a ball valve mystery?

Ball Valve Birth Pains

Ball Valve researchers point to a spherical ball-type valve patented in 1871 led to the invention of today’s ball valve. This ball valve was an all brass valve- brass ball and brass seats. Apparently this ball valve didn’t storm the market and was not mentioned in valve catalogs of the late 1800’s while today’s ball valve is quite a recent invention; the idea for this ball valve has been around about 125 years. The first resilient seated ball valve patent was issued in April, 1945. Legend has it the company’s marketing department could not envision a use for the valve and it was not manufactured. Oh well, that’s the way the ball valve bounces…Given the huge reliance on the ball valve today, it’s a mystery why it took so long for people to invent and use the ball valve.

A Comprehensive Overview of Tubular Heater Elements

Posted on by

If you have an application that requires a uniform heat source over a distributed area, then a tubular heater is probably the best heating source of choice. These heaters are flexible in that they can be used for a myriad of different applications. Tubular heaters can be designed in several different dimensions, shapes, and configurations. In fact, they are so versatile that they can be formed into virtually any shape.

Sheath materials and heater shapes

The sheath material of these heaters is selected according to the material to be heated and other specific requirements of an application. Some of the commonly used sheath materials include: 304/316 stainless steel, aluminum, incoloy, steel, copper, and so on. The sheath material also allows the heaters to be precision formed. When precision formed, such heaters can be securely fitted into the milled grooves of many different types of surfaces.

The voltage ratings of such heaters, too, can be designed in keeping with the specifications of your application.

Termination options on tubular heating elements

The terminations on such heaters can be either standard or completely customized. Here too, it is the nature of the application that determines the choice of termination. The commonly used termination options on a tubular heater include a threaded stud terminal, bulkhead fittings, or flexible lead wire. However, if your application is likely to witness exceptionally harsh conditions or high-moisture environments, custom sealed terminals should be chosen to enhance process safety.

With the right design and right terminal choice, tubular heaters provide unmatched efficiency, versatility, and economy in operations.

However, it is very crucial to ensure that these heating elements are designed with a precision fit. This helps optimize the transfer of heat to the working surface. There are several different ways of mounting such heaters-they can be clamped on the edge of a the vessel containing material to be heated, cast into metal, immersed directly into the materials to be heated, and so on.

Uses and applications of tubular heaters

The industrial, commercial, and consumer-based uses of tubular heating elements are many. However, they can be classified into the following major categories:

  • Air heaters: These are commonly used in ovens, radiators, hot air curtains, radiators, and infrared heaters.
  • Immersion heaters: The typical applications of such heaters include boilers, electrical water heaters, dishwashers, washing machines, medical and industrial equipment, sterilizers, coffee machines, and so on.
  • Defrost heaters: Such heaters are widely used in industrial freezers and refrigeration systems, compressors, and for out-door use.
  • Industrial heaters: An industrial tubular heater is commissioned in fields of application such as chemical tanks, steam generators, process air, oil or water, and in industrial ovens or batch ovens.

When selecting a manufacturer for sourcing heaters, it is important to choose a firm that has a long-standing reputation in the market.

Electric Steamers and the Many Benefits Of Steaming Foods

Posted on by

One of the easiest to use and versatile appliances in the kitchen is an electric steamer. You can find electric steamers under other names such as rice cookers and food steamers. Either way using a steamer to steam vegetables or your rice is a great and easy way to prepare delicious meals.

When cooking vegetables in a traditional way, in a pan on a stove, you can sometimes end up with mushy and pale Looking vegetables. Often the water you cook the vegetables in carries more nutritional value than the actual vegetables you have cooked. The water absorbs all the vitamins and minerals that the vegetable is known to carry. When cooking such vegetables with a pan on the stove, we tend to overcook them until they are pale and soft in texture. If you use a steamer to cook your vegetables it will prevent overcooking from taking place. Using an electric steamer, water is evaporated through a valve, leaving you with beautifully cooked, nutritious and succulent vegetables.

Cooking rice perfectly is a skill in its own right and a difficult one to master that! It’s not uncommon to get impatient while waiting for the rice to be cooked properly and completely tender when using traditional methods. Sometimes you can even scorch the bottom of the pot and give the rice a burnt taste. Using an electric steamer to cook rice means you cook it to perfection every time because most of them come with built-in timers. Everything is taken care of for you leaving you with delicious, tender rice.

You may be surprised to know that it is possible to cook a whole meal in one of these electric steamers. This proves to be a time saving practice because you can put all the ingredients in at once and cook them together using the inbuilt timer means you can sit back and relax.

Sometimes you can end up purchasing large electric steamers if it suits your family life better. These steamers often come with baskets which keep foods separate. This means you are able to cook more than one food at the same time. Electric steamers are incredibly practical and healthy to use and I’m sure the more you use your electric steamer to more uses you will find for it.

If you are interested in purchasing an electric steamer, why not have a look around for some cookbooks which are designed give you some imaginative and creative ways to cook delicious, succulent, and healthy food. A good place to start is Amazon.com as there are many books available very cheaply there. Alternatively you also many websites dedicated to the subject.

Powder Metallurgy

Posted on by

Powder metallurgy was formerly known as lost art. Not like clay or other stoneware materials, the skills in molding and firing useful and ornamental metallic objects were seldom applied in the early phases of history.

Metal powders like gold, copper and also bronze and many other powdered oxides specifically iron oxide which are used as colors, were utilized for ornamental uses in ceramic objects, used as base in paints and inks and also in cosmetics since the start of history. Powdered gold has been used in illustrating several manuscripts in the early times. The procedure in producing the powdered gold was not known, but it was possible that lots of powder were taken through granulation after the melting of the metal. Low dissolving points as well as resistance to corrosion favored the procedures, particularly in production of gold powder.

The utilization of these fine particles for pigments or decorative purposes is not a real powder metallurgy, since the important features of the current art are the creation of powder and consolidation into the hard form by means of putting force and heat at the warmth below the liquefying point of the main element.

The two principal techniques utilized to shape and consolidate the ceramics or powder metallurgy are sintering and injection of metal molding. Current improvements have possibly done to make use of speedy manufacturing techniques that use metal powder. Due to this method the powder is not sintered but melted so better mechanical power can be attained.

A much broader assortment of products might be attained from powder processing rather than straight alloying of merged materials. In dissolving procedure the “phase rule” can be applied to all untainted and merged elements and firmly dictates the sharing of solid and liquid stages which may exist for particular compositions. Furthermore, the entire body liquefying of starting substances is needed for alloying, hence, commanding annoying element, thermal and suppression limitation on manufacturing. Unluckily, the management of aluminum/iron tiny particles poses principal problems. Other materials that are principally reactive by means of atmospheric oxygen like tin is sintered in unique atmosphere or by means of temporary coatings.

In ceramics or powder metallurgy, it is probable to produce components which would disintegrate or decay. All concerns of solid-liquid stage changes may be overlooked, so powder procedures are more supple than forging, casting or extrusion techniques. Controllable character of products set by the use of several powder technologies including automatic, magnetic and some unconventional characteristics of such substances as spongy solids, aggregates and inter-metallic compounds. Competitive distinctiveness of production procedures can also be regulated strictly.

Products of powder metallurgies at present are used in the broad range of business, from automotive as well as aerospace applications into power apparatus and household appliances. Every year the international awards for powder metallurgy highlight the increasing capabilities of the expertise.

A Brief Introduction to the Planetary Speed Reducer

Posted on by

The planetary reducer is an industrial product which has a wide range of applications. Its property can compare beauty with other military speed reducers, but its price is equal to the price of the common industrial goods. Therefore, it is very popular in a lot of industrial fields.

In the passage some basic concepts of this speed reducer will be introduced in order to help people get a general idea quickly. What comes first is about its series. It refers to the series of the planetary wheel. Sometimes, because a set of planetary wheels can not meet the relatively big transmission ratio, there is need to increase one or two sets of the wheels in order to satisfy the requirement of the transmission ratio. With the increase of the gears, the length of this speed reducer will correspondingly be increased and the efficiency will be reduced to some degree. The next concept is about backlash. The so-called backlash means a tiny angular displacement. The unit for this backlash is “minute”, which means sixtieth of one degree. Back clearance is another name.

Since people get some ideas about this speed reducer, it is turn to talk about its functions and features. As far as we know, the main transmission structure of the planetary speed reducer includes planetary wheel, sun wheel and outer ring. Compared with other speed reducers, the planetary reducers are characterized by the following features, such as high rigidity, high accuracy, and high transmission efficiency, high ratio of twisting moment and cubage and maintenance for life. On basis of these features, most of the planetary reducers are installed on the stepper motor and actuating motor.

Their main functions are to reduce the rotating speed and increase the torquemoment. They also play an important role in matching the inertia. What’s more, it has also other unique features besides for the above-mentioned merits. Its cubage is quite small, its weight is light, its loading capacity is high, its service life is long and its operation is very stable without loud noise. Owing to its different features, it is indeed very popular in different fields, such as engineering plant, metallurgy, mine, petrochemical industry, construction machinery, light industry, automobile, ship and weapon. The temperature of this reducer ranges from -25 to 100 Celsius degrees. At the same time, the working temperature can be changed through changing the lubricating grease. All in all, this reducer is very popular in the industry.

Oil Seals

Posted on by

In terms of an oil seal, there are a lot of different types. Depending on how they are constructed, U-ring oil seals as well as block vee rings can be used as a rod seal, a piston seal or even a symmetric seal. U-rings and block vee rings are called single acting seals, also known as unidirectional seals, and have to be mounted back to back in cylinder applications that are double acting.

A Block Vee seal is really more compact and performs better under high pressure conditions than a U ring does. V ring seals are made of all rubber and are primarily used to get rid of dirt and other types of contaminants. V rings are stretched over a shaft and sealed against the side of housing or another type of machine component. Besides, more oil seals are introduced as there are several different kinds of clearance seals, also known as labyrinth seals. The one feature they all share with each other is that they all work on a principle of positive clearance. This means that there isn’t any rubbing that occurs against the shaft or the housing.

A lot of labyrinth seals are made up of a rotor, which rotates, and a stator, which is static, piece with a radial gap between the two pieces. The gap has to be bigger than the radial clearance of the bearing that is being sealed. Also, the operating speeds as well as the temperature have to be considered when utilizing a labyrinth seal. These kinds of seals typically don’t perform very well at lower operating speeds.

Another type of labyrinth seal is a laminar sealing ring, which utilizes a series of flat metal rings, similar to washers, of different diameters to make a labyrinth seal. Bearing isolators are a dynamic kind of seal that is designed to keep bearings protected from outside elements. They are also made up of a rotor, a rotating piece, and a stator, or static member. Some bearing isolators are made out of labyrinth construction but others use O rings or other kinds of positive seals.

To Eliminate Noise from a Switch Mode Supply

Posted on by

A switching mode power supply is very efficient in its working. Although, the supply is designed in such a way that it produces noise that is inaudible to the human ear, it sometimes gives a lot of noise especially when it gets old.

The good news is that if your switching mode power supplies producing a lot of noise there are ways in which you can eliminate the noise.

 

High-pitched whine with a fan

The noise is caused by lack of lubrication in the fan bearing. To eliminate the noise you should lubricate the bearing. This calls you to unplug the device from the power supply and remove the fan’s bearing protective plating. You should then put a few drops of sewing machine oil directly onto the bearing.

You should note that some protective plating is held by screws while others are held by a thick sticker.

High-pitched whine without a fan

This noise is usually caused by external electromagnetic interference (EMI). To solve it you need to move the power supply away from anything that produces a large amount of EMI. Some of the objects that tend to produce a lot of EMI include: large speakers, large batteries, fluorescent lights and flat-screen monitors.

If you remove the supply from these objects and the noise persists, it must have been caused by a dry capacitor. You should remove the capacitors together with the soldering iron and then replace them with new capacitors.

You should note that capacitors have the ability of causing massive electronic shock; therefore, after unplugging the power supply you should leave it unplugged for at least three hours before you remove the capacitors.

Low-pitched hum

If the low-pitched hum is annoying, you should put the supply in a metal casing in order to shut the noise in the casing. All you should do is to visit your local store and find a casing that will fit your entire power supply unit. You should then place the supply inside the casing and screw the casing shut.

Conclusion

These are some of the ways in which you can eliminate the noise in a switching mode power supply unit. If you do all of the above and the noise persists, you should take your device to a professional who will rectify the problem for you.

To ensure that your device lasts for a long time without developing problems, it’s good that you buy your device from a reputable seller.

Pallet Truck: For Large Weights

Posted on by

Pallet Jack scales also known as a pallet truck is an ideal tool which is typically used to weigh a variety of large items including pallets, drums, kegs and barrels. In a pallet jack scale, the forks are separated from the front wheels as the hydraulic jack is raised forcing the load upward until it clears the floor. The pallet is lifted as much as necessary to clear the floor for subsequent travel. In just one operation, one can lift the load, read its weight, and move it to its destination using the Pallet Jack scales.

This scale is ruggedly built to be cognizant of the extensive industrial use. It delivers reliable weighing results or counting results wherever it is used. These scales are used to speed up the warehouse and shipping processes. Heavy duty Pallet Jack scales can be used for permanent or portable installations. The adjustable leveling feet and the optional four-way ramp access make the loading process simple.

A typical scale consists of one set of pallet, an indicator box (with indicator), a junction box and a built-in printer which is optional. There are different types of Pallet Trucks in the market. An ideal scale should have a leak proof design, extra roller for easy moving, plastic bonded three lever positions, easy to operate, silent in operation, minimum pulling power, no oil leakage, minimum maintenance and maximum mobility. There should be a constant floor contact and stability. The wheels should sustain heavy loads and hence minimize wear and tear. The Pallet Jack scale should provide for easy operation from all angles ergonomically.

A scale should be designed to reduce the pulling power and minimize operation fatigue. Some of the key specifications of a Pallet Scale are the load capacity, lowest fork height, highest fork height, turning wheels, load wheel single, load wheel double, fork size, fork overall width and fork length. Self-Propelled Electric Pallet Truck and Pallet Jack with scale, 4500 lbs, are some of the latest Pallet scales available in the market. Ergonomic handle features, easy to operate throttle with infinite forward and reverse speeds, lift / lower controls, horn and safety-reverse button are some of the features of these models.

The drive motor controller prevents unsafe starts after the safety-reverse button has been inadvertently struck. Double reinforced welded forks with adjustable tie-rods increases the years of service. Electromagnetic disc brake with automatic dead-man feature activates when the user releases the handle. An integral battery charger and a battery level gauge are included in these models.

The pallet scale rolls smoothly on the polyurethane, steer and load wheels making them one of the most reliable tools. A pallet scale maximizes efficiency by eliminating wasted time and floor space when checking inbound and outbound shipping weights of up to 5000 lbs. One can conclude that quick verification of incoming / outgoing freight, checking weights anywhere in the plant, in transit without hauling loads to a platform, all-purpose mobile scale, batch and drum filling and inventory control are a few of the many uses that a Pallet scale can offer.

Pallet Jack Scale
Scales are used for taking various measurements, whether it is weight, volume or mass. Now-a-days digital scales are used largely. Scales give the measurement which is required while disposing anything or to accommodate anything.
