30 JulHow to Choose the Right Pressure Transmitter

A Pressure Transmitter is a device that measures the amount of pressure exerted by gas or liquid. The instrument is used to control pressure levels on the flow of gas or fluid, the speed as well as the level of these substances. Currently, there are different technologies used to perform such functions. The capacity of each transmitter varies and it can affect the cost depending on its performance and suitability of application. Thus it is important to consider different aspects when it comes to choosing the right tool to use.

Types of Pressure Calibrator

Before deciding on the kind of pressure transmitter to purchase, it is important to familiarize yourself first with the available options. The kinds of pressure transducer vary depending on its industrial use. The ACONE pressure flow meter, for example, uses the technology which makes it capable to handle different types of fluid. It is also made to operate even under the harshest environmental condition. Another type is the ALDP-3051 which utilizes microprocessor and digital technology which makes it useful when it comes to acquiring differential and absolute pressure. It also other features such as self-diagnosis and communication protocols. It also allows customization to make it compatible with different types of applications. The ALDPWG meter, on the other hand, is another type of differential pressure wedge meter which is aimed in measuring low flow of fluid. This device is usually utilized for measuring pressure among liquids with high-viscosity such as oil, dirty liquid, waste water and the likes. It can also be used to measure steam and gas, apart from liquid.

Choosing the Pressure Gauge

In addition to choosing the right pressure transmitters, it is also important that you put consideration on the kind of connection that you will be using. The traditional types include the flange and the cone. The connectors are also crucial since they will also determine the kind of pressure flow in the upstream and downstream of the element. Some pressure transducers can be customized on the kind of connection, depending on the application. But you have to be aware of the effects of the kind of connector that you will be using so you can maximize its usage.

Selecting your Device

It is important that you look for high-quality pressure transmitter. Search for ones that are calibrated to ensure accurate readings every time. Uncalibrated transmitters can also be considered useless, so don’t fall into the trap of purchasing it just because it is way cheaper than the ones that you see in authorized dealers. In addition, make sure that your transmitter complies with industrial standards. Obtain your equipment from a reliable seller so you know that you are getting genuine parts on your pressure flow measuring device.

Smart Measurement Inc. is the best provider of Pressure Transmitter that is capable of differential, gage, or absolute pressure measurement with digital communications and capacitive sensor technology. The ALPD-3051 pressure transmitter is available in a wide variety of features to make it suitable for almost any application.

29 JulThings You Need to Know About A Globe Valve

Valves are categorised into two types, the stop valves, which gives an on, off or fractional on setting, as well as check valves, which stops the flow of fluid in only a single direction. A globe valve belongs to the top valve family. These valves are like their description. Their valve body is rounded and is made up of two distinct halves, which are isolated by a disc that closes or opens. Unlike the other valves, this is more complex because it is made up of a bonnet, body, stem, plug, seat ring and cage.

The globe valve is composed of a baffle that splits the inside of the pipe, which is typically parallel to the pipe’s length. The baffle has an opening that is vacuum-packed using a flat plug or a disc that is pushed down in the seat or opening parallel to the pipe to break the flow inside the pipe. Outside the pipe, a structure identified as a bonnet holds a stem that is joined to the disc. At the upper part of the bonnet is the hand wheel that is utilized by one’s self to screw down the stem including the disc at its end till the disc seals itself touching the seat opening. When the globe valves are used in big industries, they can be closed through the use of a pneumatic, electrical of hydraulic actuator rather than a manual hand wheel.

These apparatus are at times mentioned as throttle valves due to the fact that these can limit the flow inside the pipe. The space with which the liquid can flow is reduced if the sealing disc is relocated halfway going to the seat opening thus limiting the flow. This valve type provides excellent control to normalize the fluid flow. Water pipes are mostly fitted with these types of valve so that the operator can regulate the water flow inside the pipe by opening the valve partly or completely opening it.

This valve can also be installed to close with or against the liquid flow. When the liquid flows in the similar path that the disc is closing, the flow will assist in closing the seal but makes opening more difficult. On the other hand, if the flow is against the path of closure of the disc, it will be easier in opening the valve and harder when closing it.

29 JulUsages and Advantages of the Horizontal Band Saw

First, a vertical band saw and a horizontal band saw are different band saw tools, which can be used to work on metals to achieve different things. The horizontal kind is typically used in making cuts in large work pieces since it possesses capacity to do this. While a vertical type which uses less power makes continuous cuts by utilizing its circular endless blades. It has the capacity to perfect complicated cuts. A band saw is a power tool that can be used for working on metal, wood and for cutting other types of materials such as plastic. Which means a lot of power will be consumed when using this tool, therefore, one important consideration to have when getting a band saw is power consumption required by the particular type you are buying. If what you will be using the band saw for is cutting through large logs, then much power will be required and this means increased energy bills for you. In addition to this, another consideration you should have when getting a horizontal band saw or the vertical type is the kind of blade you will require. This is necessary as the type of blade you procure determines cuts made. In other words, different blades make different cuts. For more information on this, ensure you speak with a sales representative.

The other concerns, which you should bother yourself with in this article pertain to vertical band saw in particular and they are the table size and the accessories. It is better and wiser in buying a larger table as this will give more prop for long and wide materials when you want to work on them. And for accessories, you should get a rip fence and miter gauge as these are beneficial to this band saw type.

On a final note you should always check the product label of any band saws you wish to purchase. Check for the rating, the product, motor, dimension specification. And also ask questions from the sales personnel when you need to get clarifications on things you don’t understand. Following the considerations stated here should put you in a good position when attempting to buy a horizontal band saw or its vertical counterpart..

28 JulA 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.

28 JulOil 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.

27 JulWhat is a Pallet Truck?

A pallet truck, also know as a pallet jack or pump jack, is a manually powered fork truck designed to lift and move heavy materials. The front wheels are placed on the inside near the forks at the front. At the back is a hydraulic jack which is used to lift the pallet off the floor.

How do use a pallet truck? 

Being manually powered the person operating the truck pushes the forks into the pallet, and then uses the jack part of the truck to ‘jack’ up the pallet off the floor to a certain height required. Once the pallet has been lifted the operator can then move the truck where ever they wish, the pallet is only listed off the ground so it can be moved, and so a foot or so is usually normally.

Powered pallet trucks

Pallet trucks are also available powered. It is the same principle as a manual pallet truck except instead of the operator having to jack up the pallets the machine lifts it for you via controls. This is easier to use as the machine does most of the work for you and they can lift heavier pallets if required.

Who uses pallet trucks?

Generally speaking pallet trucks are used by people who are suppliers and work in warehouses. This can be in a variety of fields such as food and drink, clothing, computers, machinery and so on. Any industry that requires moving about large and heavy pallets of products will use a pallet truck.

How much do pallet trucks cost?

Many companies will differ slightly in the cost of their pallet trucks, and depending on the type of pallet truck will alter the cost as well. You will be able to pick up a regular pallet truck for around £130. Searching online or visiting different shops you’ll be able to gain more of an idea of the prices available.

27 JulServer Racks and Computer Server Rack Evolution

It has been interesting over the years to see how words morph so quickly in the computer IT arena. A good example has been how the term server rack evolved from the phrases enclosure cabinet, data cabinet and computer rack that was made to hold computer hardware on 19″ EIA rack rails.

Most of these type enclosure cabinets were shallow from 20″ to 25″ deep and were basically the same for many years. Things began to change when deeper cabinets were needed as blade servers became more popular several years ago. Until blade servers entered the market, most servers were towers or 15-20″ deep that could be rack mounted in 4U-8U space.

Many popular blade servers were designed to only take up 1U-4U of space. This created the opportunity to put a lot more servers in a computer rack. An interesting problem was created however when blade servers were put in such a small “U” space. The servers became much deeper, up to 42″ deep in some cases, and also ran much hotter. Heat disperse was addressed by pulling air from the front of the server and blowing it out the back.

These deeper hot running servers no longer worked well in a conventional enclosure cabinet or computer rack and a new style computer rack was developed. This cabinet had to be deeper and allow for airflow from the front to rear to keep the servers from burning up. The industry term began to morph to server racks.

The rack rails of the server racks also changed from a long time standard of 10/32 tapped rack rails to a punched square hole that held an insert for a 6mm cage nut and screw. Dell, along with other manufactures, makes sliding rails that attach to the server rack with a special flange that fits into the square hole without the use rack screws.

Currently, server racks are made in many versions. Some have a combination plexi door with special vents cut in the frame for the front door and a screen rear door. Other server rack versions have a locking screen door in front and a double screen door in the back to save space as it opens into an aisle.
