The advantages and disadvantages of water ring vacuum pump analysis _

Compared with other types of mechanical vacuum pump, water ring vacuum water pump has the following advantages:

( 1) Simple structure, manufacturing precision is not high, easy processing. Easy to operate, easy to maintain.

( 2) Compact structure, the pump is usually connected directly to the motor, high revolutions. The smaller the structure size, larger displacement can be obtained.

( 3) No metal friction surface, water ring pump cavity without lubrication pump. Rotating seal between artifacts and fixed components can be conducted directly by a water seal.

( 4) Compressed gas water ring pump chamber temperature change is small, can be thought of as isothermal compression, so it can remove inflammable and explosive gas.

( 5) Because there is no exhaust valve and the friction surface, can remove dust, gas condensable gas and water mixture.

the disadvantage of water ring vacuum pump

( 1) Efficiency is low, usually for about 30%, optimization of 50%.

( 2) The vacuum degree is low. This is not just because structure limits, more important is because of the working fluid steam pressure.

usually, water ring vacuum pump has the advantages of wide isothermal compression and as sealing liquid water, for example, it can remove inflammable, explosive and corrosive gas, and you can also remove gas containing dust and moisture. Applications.
