Abstract:In view of the problems that the circulating water system of vacuum pump is easy to be blocked, the pump maintenance frequency is high, and the process operation is often "paralyzed", Carry on the technical discussion, the factors affecting the blockage of circulating water system are analyzed, targeted optimization and transformation were carried out. After transformation, the drainage capacity of the circulating water pipe is improved, the maintenance rate of vacuum pump is reduced, the production stability and operation rate of rotary kiln are ensured.
