What are the different uses of vacuum pumps? What do you need to know?

A vacuum pump is actually a device that pumps air or water out of a sealed container to form a vacuum. This is nothing new. The first vacuum pump came out in 1650. However, it has not been until recent decades that we have witnessed how such devices are used. So, what are the different uses of vacuum pumps?

There are many industrial uses. The most common possibility is the electric light. Yes, the lamp uses a vacuum pump to pump the gas out of the bulb so that it can emit light. In addition, vacuum pumps are also used for semiconductor processing. But this is not the end of the story. In aircraft, some gyroscopes of flight instruments are powered by vacuum power supply in case of electrical failure.

There are many kinds and uses of vacuum pumps. Although classification is a complex process, it may be reduced to two categories. The first is the conveying pump, and the second is the clamping pump. Trapping pumps trap molecules into a limited space. For example, cryopump and ion pump. The former captures liquefied gas molecules, while the latter captures ionized gas.

On the other hand, transfer pump is also called power pump. For example, it uses momentum to transport gas from vacuum to exhaust gas, just like a turbomolecular pump.

Vacuum pumps can also be divided into mechanical vacuum pumps and compressed air vacuum pumps. According to Bernoulli principle, compressed air pump relies on pressure difference to produce vacuum. At the same time, the mechanical vacuum pump has a motor as the power source, although it can also use the internal combustion engine to draw air from a closed volume and release it into the atmosphere.

Perhaps the most popular mechanical vacuum pump is the rotating blade, which has a separate rotor around a high-speed rotating shaft. This traps the air and passes through the intake, leaving a vacuum.

As you can see from the above, simple vacuum pumps have many different uses in different industries. It is basically a universal device with only one function, but it can be customized and added to meet the needs of specific industries.

Similarly, different pumps have different uses, so the prices are different.
