What types of vacuum pumps are there?

From the working principle of vacuum pumps, the most commonly used types of vacuum pump are reciprocating vacuum pumps and rotary vane vacuum pumps.

It is widely used in metallurgy, chemical industry, food, electronic coating and other industries.

1.1 Reciprocating vacuum pump
The W-type reciprocating vacuum pump is one of the main equipment for obtaining rough vacuum. It is used to extract air and other gases from closed containers or reaction pots. It is not suitable for extracting corrosive gases or gases with hard particles of ash.

The reciprocating vacuum pump has the advantages of small size, simple maintenance, and long valve life. It is suitable for use in a higher pressure range, with an ultimate vacuum of about 2000Pa.

1.2 Rotary vane vacuum pump
  The water ring vacuum pump is the most typical type of rotary vane vacuum pump. The water ring vacuum pump is equipped with an eccentric rotor with fixed blades, which throws water (liquid) to the stator wall. The water (liquid) forms a liquid ring concentric with the stator. The ring and the rotor blades together form a rotary variable volume vacuum pump with variable volume. The water ring vacuum pump is a rough vacuum pump, and the ultimate vacuum it can obtain is 2000~4000Pa.
