What should I pay attention to when using Roots vacuum pumps?

1. The use of Roots vacuum pump must be equipped with a backing pump and is not used alone.
2. Roots vacuum pump is mostly used in Roots vacuum unit, its role is to improve the pumping speed and the vacuum degree of the backing pump. Roots pump in the connection with the backing pump need to be equipped with bypass valve, which can effectively protect the roots pump, if the pumping of the back pump is unstable or other factors lead to the operation of the entire unit is not normal, the roots pump with bypass valve will play a role in protecting the roots pump at this time, thereby prolonging the life of the entire vacuum unit.

3. Roots vacuum pump in the use of the process if the vacuum is reduced, at this time need to check whether the gap between the rotor of the Roots vacuum pump has changed, if the rotor gap of the Roots vacuum pump becomes larger, you need to replace the Roots vacuum pump, because such Roots vacuum pump in the production and processing process does not do static balancing of the Roots vacuum pump rotor, or the bushing is sealed.
4. When choosing Roots vacuum pump, you need to pay attention to the sealing method of the vacuum pump wearing parts of roots vacuum pump, the general Roots vacuum pump uses a mechanical sealing method, which can effectively improve the efficiency of Roots vacuum pump, if the vacuum pump sealing method of Roots vacuum pump chooses bushing sealing, the work efficiency will be greatly reduced, and special attention needs to be paid when choosing Roots vacuum pump.
