Vacuum pump is a compressor that sucks gas out of thin air space and discharges it into the atmosphere. Generally, the pressure of the gas it sucks out is lower than the atmospheric pressure (the vacuum pump manufactured recently can make the residual pressure in the vessel 1 x 10-15 mm silver column), and the pressure of the gas it exhausts is slightly higher than the atmospheric pressure.
Vacuum pumps can also be distinguished by reciprocating and rotating pumps, and their working principles are the same as those mentioned above. At present, there are wet and dry vacuum pumps used in concentrators.evp-cl-liquid-ring-vacuum-pump-feature
Dry vacuum pump only sucks air from a certain space (such as air in the filter), and can suck up 98% of the air, while wet vacuum pump sucks liquid and air together, and can only suck up 85% of the air.
In order to maintain a certain volume of water ring and discharge heat, water must be continuously circulated. In order to supply water to the vacuum pump, a special water tank connected with the discharge pipe is installed, and a gate valve on the tank is used to regulate the circulating water volume.
The used water is put into the box with air. In order to avoid blade end wear, there should be no inclusions in the circulating water, otherwise the blade will be worn, and the exhaust volume will decrease with the increase of wear; the general wear should not be greater than 0.1 mm.rotary-vane-vacuum-pump-technology
