Vacuum pump features classification

Any machine that takes out gas from the equipment and makes the inside of the equipment reach a vacuum is called vacuum aspirator or vacuum pump. From the structure of the vacuum pump can be roughly divided into: reciprocating vacuum pumps, rotary vacuum pumps and jet vacuum pumps. 1, reciprocating vacuum pump Reciprocating vacuum pump is suitable for pumping non-solid particles, non-corrosive gases. This vacuum pump pumping speed larger vacuum degree higher. It is widely used in chemical plants. However, its complex structure, large amount of maintenance. 2, water ring vacuum pump. Water ring vacuum pump is a rotary vacuum pump. 3, jet vacuum pump. Jet vacuum pumps use a higher pressure working fluid to deliver another fluid. Circulating water vacuum pump is widely used in evaporation distillation, crystallization, filtration, vacuum, sublimation and other operations, low temperature cooling circulating water vacuum pump is a combination of vacuum pumps and cryogenic cooling pumps. Which can be evacuated, but also to provide low-temperature cooling circulating water, vacuum distillation and decompression enrichment is a good auxiliary equipment, especially adapted with a rotary evaporator, not only reduces the use of space, but also reduces the degree of vacuum, saving water, Widely equipped by modern laboratories.
