Model of water ring vacuum pump

The water ring vacuum pump has various types according to the different air pressure and vacuum required by the application field. While working, attention should be paid to two aspects. One is to operate in the critical area as much as possible to ensure the production of the machine. Second, avoid operating near vacuum or exhaust pressure. If operating in these two environments, the production efficiency may be low, and machine failures may occur.
According to these two considerations, it is easy to choose the type of water ring vacuum pump. When the vacuum or gas pressure required by the pump is not high, it can be selected from the single-stage pump in priority. If the vacuum degree or exhaust pressure is high, the single-stage pump is often unable to meet the requirements, and the performance curve is flat when the vacuum degree is high, the two-stage pump can be selected. If the vacuum degree is required to be above -710mmhg, water ring atmospheric pump or water ring roots vacuum unit can be selected as the vacuum pumping device. If it is only used as a vacuum pump, it is better to choose a single acting pump. Because the single acting pump is simple in structure, easy to manufacture and maintain, and has good cavitation resistance under high vacuum. If it is only used as a compressor with a large amount of air, it is appropriate to choose a double acting pump. Because the double acting pump has large air volume, small volume, light weight, and the radial force can be automatically balanced, the shaft is not prone to fatigue fracture, and the service life of the pump is long.
The preliminary selection of water ring vacuum pump has certain requirements for the working environment and process, but it is necessary to select the appropriate machine in this industry to meet the subsequent production requirements. Later articles will introduce more knowledge about water ring vacuum pump. Please look forward to it!
