A wide range of vacuum pumps, so its functional characteristics are also different, from the structure of the vacuum pump can be roughly divided into: reciprocating vacuum pumps, rotary vacuum pumps and jet vacuum pumps. Vacuum Pump Next, we mainly analyzed the features of these types of vacuum pumps. 1, reciprocating vacuum pump: reciprocating vacuum pump for pumping non-solid particles, non-corrosive gases. This vacuum pump pumping speed larger vacuum degree higher. So 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 pump is the use of a higher pressure working fluid to transport 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. After the vacuum pump begins to work, it continually pulls out the gas in the container and gradually reduces the pressure in the container. When the gas pressure in the container drops below a certain minimum value, several situations may occur: the liquid in the container is vaporized ; Pump back to the high-pressure side of the gas leakage and the amount of vacuum pumping the same; vacuum pump pressure ratio is too high, so that the suction process is terminated. Now advances in technology, the rapid development of vacuum pumps, vacuum pumps to understand the functional characteristics of the promotion of the entire industry is also crucial.
