A Comprehensive Overview of Tubular Heater Elements

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.

Powder Metallurgy

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

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

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.

Rotary Die Cutting

Rotary die cutting is a process used to cut paper, metal, rubber, plastic, vinyl and other material in a predetermined shape and size. This method is used to cut shapes and designs that cannot be accomplished by a straight cut on a web press or a guillotine cutter.

The rotary cutter uses knife-edge cutting blades designed to cut a particular shape. A machine presses the die into the material to produce the desired shape. The blades can be designed to cut a diverse range of raw materials. Labels, envelops, folders, cartons and documents are just a few items produced using the rotary die cutting process.

The cutting dies used in the rotary die cutting process are made from tungsten carbide. It is a very hard and expensive substance used in high volume production processes that justifies the extra costs incurred. Perforated blades or dies are used to form perforations on paper. These can be used for making receipts books, bills and tickets. Rotary die cutting equipment for industries involves relatively low upfront costs ranging from $50,000 to $70,000. However, the cost of replacing old and worn out blades is high.

One major drawback of rotary die cutters is that changeovers are time consuming and difficult. This is because they require excessive amounts of material to re-register the printing to the desired cutting and creasing specifications. Rotary die cutting equipment only registers in the direction of travel. If the material shifts in any other direction, defects begin to appear.

The rotary die cutter process is economical over a longer period. It is extensively used in manufacturing industry and stand-alone die cutting firms. However, the technology is changing at a fast pace, and new processes like laser die cutters are already in use. These are much faster and accurate than rotary die cutters.

About Spiral Bevel Gears and Its Comparison with Hypoid Gears

Spiral bevel gears are gears with helical teeth. These gears are used in the differential of a vehicle where the drive’s direction must be turned at an angle of 90 degrees from the drive shaft to drive the wheels. The helical design facilitates less vibration and noise in comparison to the traditional spur-cut gears with straight teeth.

As the Spiral bevel gears are lapped and manufactured in pairs, it is advised that one should replace them in pairs, i.e., both the left hand and the right hand gear should be replaced together when either gets damaged.

A right hand gear is the one in which the external half of a tooth is inclined from the axial plane via the midpoint of the tooth in the clockwise direction. This is based on the observation of a person who looked at the gear’s face. On the other hand, the left hand gear is one whose tooth’s outer half is inclined in the anticlockwise direction from the axial plane and through a tooth’s midpoint. However, it is to be noted that both the right and left hand designations are applied similarly to other types of gears such as the hypoid, oblique tooth face, and many other.

Hypoid is a kind of gear whose axis does not intersect with the meshing gear’s axis. The shape of a hyploid is a revolved hyperboloid, while the spiral bevel are conical. A hypoid places the pinion off-axis to the ring gear. This allows the pinion to be larger in diameter, thus having more contact area.

The pinion and gear are always of opposite hand in a hypoid gear. It incorporates some sliding and can be considered as the midway between a worm and straight-cut gear. A hypoid gear requires special oils to ensure smooth sliding action under extreme conditions between the teeth.

Comparison between Spiral Bevel and Hypoid Gears

Although hypoid gears operate more quietly, they also have some sliding action which reduces their mechanical efficiency. Earlier, hypoid were used in rear-drive automobile drivetrains, but their modern designs have made them a neat substitute of the spiral bevel.

A hypoid is still common in trucks due to the capability of trucks in transmitting higher torque. However, one cannot replace hypoid with the spiral bevel gear in automotive because the latter requires a much larger diameter in comparison to the former one to transmit the requisite torque.

Prakash Gears is a leading manufacturer of different types of robust gears in all of India.

5 Easy Steps to Installing a Pressure Tank

If you live in a regular suburban-style home or are thinking of moving into one, one of the things you might have to consider getting initially for your home is a pressure tank. It is a device that uses compressed air to push water from a water source upward. In homes that have two or more stories, they are needed to push water from a ground water source to the plumbing fixtures above. Without it, you won’t be able to use water in the upstairs part of your home, especially if the ground water source doesn’t have a very strong force.

Getting a pressure tank is easy but requires a bit of research as you need to know what type is appropriate for your home. You can consult with a professional when in doubt, but the process is fairly straightforward so long as you read the manufacturer’s instructions thoroughly. It helps to be friendly with hardware store owners that sell tanks because they can give you helpful tips on how to install it yourself.

Choose the right kind. There are various sizes. The larger ones may be more expensive, but they can hold more water so the pump switch will be turned on less, extending it’s life. There are several types available. You can get a galvanized (which is one of the oldest types), a pre-charged, an air pressure tank, and a sealed diaphragm. Do your research to check which is best for your home-try consulting with a plumber if you’re not sure.

Prepare. Pumps use electricity to be able to function properly. Be sure that you have completed the electrical connections that you need. Follow the manufacturer’s instructions for any valves that need to be installed. Certain kinds of valves need to be installed in the pump in order to allow it to re-pressurize automatically.

Check your water source. Pressure tanks need a water source from a discharge pipe, to be fitted with a gate valve according your manufacturer’s instructions. Be sure the water is clear and free of any sediments or debris. If not, let it run until it is clear.

Install the pressure tank. You will need an air volume control on it to monitor the amount of compressed air pushing the water into the pipes; it needs to be just the right amount. Place your pressure tank on a raised platform, to allow water to drain out when necessary. Concrete blocks would be good for this. Once that’s done, connect the pump to the water pipes. Test it out and allow the pressure tank to fill up until the pump automatically shuts off. Do this a few times to be sure that it works properly.

Install any water filters or water softener systems, if necessary. You’re done! Be sure to periodically check on your pressure tank to make sure that it is working at optimum conditions.

A pressure tank might just save you a lot of time!

How Manufacturers Do Aluminum Extrusion?

The process of aluminum extrusion is simple and easy however it is very significant to know why extrusion is so important. In general metals like steel and aluminum is put to use in several industries, right from automobile, to telecommunication, transport, utensil manufacturing and at times even in the toy industry. Thus, both of these metals are in huge demand and find place is almost all the major manufacturing industries in the world.

Just after steel, aluminum is the other metal which is hugely popular all over the world. This can put in a manner stating that aluminum is the second most popular metal in the globe after steel. The former is widely available, has impressive properties, and is affordable, light weight, can withstand high temperatures and so on. And above all the aluminum extrusions involved in getting different shapes and forms for suppliers is cost-effective and simple. Both in US and Europe building industry and the telecom as well is highly dependent on aluminum extruded products. These products find a number of usages and are used in many applications.

So, what is aluminum extrusion? This is a process through which aluminum is given certain shapes and forms. It starts with the hot cylindrical billet of aluminum which is pushed through a shaped die. The billet is cut from DC cast log and placed in heated container (450°C – 500°C). When pushed through the die the metal flows through the steel die. The die is placed at the other end of the container. Now, once the log passes it produces a section, this can be cut into shapes either in long length or short. The section is cuts according to the customized demands of the clients since the log is meant to be used for any particular industry. In certain extrusion process rectangular shaped billets. In this process only wide section sized extrusions are produced. This again depends according the demands of the supplier.

Aluminum extrusion is done for several kinds of industry and these aluminum extruded products are very commonly used in building industry. In this industry you can use aluminum in prefabricated houses/building structures, window and door frame systems, curtain walling, roofing and exterior cladding, and shop fronts. Besides, they also find place in the telecommunication and transport industry. In transport industry aluminum extruded products are found in rail vehicles, marine applications, airframes and for vehicles on the road.

So, what makes aluminum so popular? It is the versatility and the flexibility of the material that turns in so popular. Since aluminum is high temperature resistance and is corrosion resistant as well it is used to make utensils and is also used on transport vehicles. Besides, it is strong even though it is light weight and thus it is used in airframes.

So, if you are out there still deciding on selecting aluminum extruded products or some other metal you can give your votes to this metal as it is affordable and durable as well. No more second thoughts to this go ahead with aluminum extrusion and the products.
