How to Select Water Ring Vacuum Pump
2BV water ring vacuum pump is composed of pump body, impeller, mechanical seal system, motor, disc, pump cover (exhaust valve disc, cavitation valve), and other small parts. Its working principle is as follows. My understanding is the principle of impeller, which is driven by large space and compressed by small space. How to choose vacuum mercury in water ring?

So, which industries will use it?
Water ring vacuum pump is widely used in papermaking, chemical industry, petrochemical industry, light industry, pharmaceuticals, food, metallurgy, building materials, stone tools, coal washing, mineral processing, fertilizer and other industries.
Water Ring Vacuum Pump in Paper Industry:
1. Evaporation of Black Liquor
2. Coarse Pulp Washer
3. Lime slurry and filters
4. Precipitate filter
5. Vacuum dehydrator
6. Headbox Compressor/Vacuum Pump
7. Suction tank
8. Couch roll
9. Suction Roller and Transfer Roller
10. Vacuum pressing.
11. Wool suction tank
12. Blow-proof box
Water ring vacuum pump advantages:
1. The structure is simple, the manufacturing accuracy is not high, and it is easy to process.
2. Compact structure, high pump speed, generally can be directly connected with the motor, without deceleration device. Therefore, with a small structure size, we can get a large amount of exhaust gas and occupy a small area.
3. Compressed gases are basically isothermal, i.e. the temperature change of the compressed gases is very small.
4. Because there is no metal friction surface in the pump chamber, there is no need to lubricate the pump, and the wear is very small. The sealing between the rotating part and the fixing part can be accomplished directly by the water seal.
Water ring vacuum pump shortcomings :
The working principle, advantages and disadvantages of water ring vacuum pump are low efficiency, generally about 30%, better up to 50%.
How to choose water ring vacuum pump? Expensive is not necessarily good, cheap is not necessarily good, suitable is the best! For more information, please consult the professional manufacturer of EVP vacuum pump.
