Those taken out from the device, the device of internal gas reach vacuum machinery known as vacuum suction machine or vacuum pumps.
Structurally the vacuum pump can be divided into: reciprocating vacuum pump, rotary vacuum pumps and water jet vacuum pump, etc.

1, reciprocating vacuum pumps. Reciprocating vacuum pumps for pumping and not containing solid particle, non-corrosive gas. This vacuum pump's suction rate is large, the higher vacuum. It is widely used in the chemical plant. But its structure is complex, the amount of maintenance.

2, water ring vacuum pump. Water ring vacuum pump is a rotary vacuum pump.

3. Jet vacuum pump. Jet pump is the use of a pressure higher working fluid for the transmission of another fluid.

Circulating water pump is widely used in distillation, evaporation, crystallization, filter, vacuum, sublimation, low-temperature cooling circulating water pump is a vacuum pump and the combination of low-temperature cooling pump. That is, you can vacuum and can provide low-temperature cooling circulating water, vacuum distillation and vacuum concentration of good auxiliary equipment, the special adaptation is equipped with a rotary evaporator, which not only reduces the use of space, and reduces the vacuum, saving water, is widespread in modern laboratory equipment.
