vacuum pumps classification

The classification of vacuum pumps is not clear to many laymen. The technical staff of vacuum pumping plant sorted out the complete vacuum degree as follows, hoping to be helpful to everyone. Vacuum pumps can be divided into two categories according to their working principles:rotary-vacuum-pump-in-coal-chemical

I. Gas Conveyor Pump

1. Varistor Pump

Reciprocating vacuum pumps - mainly diaphragm vacuum pumps, piston reciprocating vacuum pumps

(2) Rotary pump

A. Oil seal pump - rotary vane vacuum pump, fixed vane vacuum pump, slide valve vacuum pump

B. Oil-free Pumps-Reciprocating vacuum pumps, multistage Roots vacuum pumps, claw vacuum pumps, scroll vacuum pumps, screw vacuum pumps

C. liquid ring vacuum pump - water ring vacuum pump and oil ring vacuum pump

D. Roots Vacuum Pump - General Roots Vacuum Pump and Gas Circulating Cooling Roots Vacuum Pump

2. Momentum transfer pump

A. Molecular Pumps - Vortex Molecular Pumps, Traction Molecular Pumps, Composite Molecular Pumps

B. Jet Pump - Water Jet Vacuum Pump, Gas Jet Pump, Steam Jet Pump

C. Diffusion Pump - Oil Diffusion Pump, Oil Diffusion Booster Pump

2. Gas trapping pump

Molecular sieve adsorption pump, getter pump, titanium sublimation pump, sputtering ion pump, cryogenic pump, condensation pump vacuum-pump-classification
