What is the selection standard of water ring vacuum pump? Many people are very confused, today for you to briefly introduce its selection criteria, I hope to help you.
1. When the unit works, the vacuum degree is stable, the power consumption is small, and the motor power does not exceed 4kw.
2. The vacuum parameter design is reasonable, the vacuum degree and pumping speed can meet the production requirements. The new vacuum pump with low vacuum and large suction should be selected. The maximum vacuum degree of the pump should not be greater than 90%, and the maximum pumping speed should be greater than 25i / s.
3. High quality water ring vacuum pump has good cooling cycle and sealing device.
4. It is equipped with automatic dewater meter.
5. It has the advantages of flexible movement, easy maintenance and long service life.
