What is a vacuum pump? How many types of vacuum pumps are there?

A machine that extracts gas from a device and makes the inside of the device reach a vacuum is called a vacuum pump or vacuum pump.

From the structural point of view, vacuum pumps can be roughly divided into: reciprocating vacuum pumps, rotary vacuum pumps and jet vacuum pumps, etc.

1. Reciprocating vacuum pump. Reciprocating vacuum pumps are suitable for pumping gas without solid particles and non-corrosive. This vacuum pump has a high pumping rate and a high vacuum degree. Therefore, it is widely used in chemical plants.

2. Water ring vacuum pump. Water ring vacuum pump is a type of rotary vacuum pump.

3. Jet vacuum pump. Jet vacuum pump uses a working fluid with a higher pressure to transport another fluid.

The working fluid of the jet vacuum pump can be divided into high-pressure steam, air or high-pressure water. The jet vacuum pump is mixed with the transported fluid (liquid or gas) and discharged together.
