What are the solutions for large fluctuations in vacuum pump current?

What is the solution to the large current fluctuations in the long-term use of vacuum pumps? Today to answer for you

(1) the vacuum pump's transport medium is too tight; solution: relax the packing gland of the horizontal pump.

(2) The speed of the vacuum pump is too high; solution: reduce the speed of the centrifugal pump.

(3) Vacuum pump's supporting motor power is insufficient; solution: adjust or replace the supporting motor.

(4) pump bending bearing wear or damage; solution: the pump shaft correction straightening bearing repair or replacement.

(5) Something is stuck; first determine whether the outlet and inlet pipes are blocked by foreign objects, and then determine whether the pump is blocked by debris.

(6) The actual head used is less than the head of the centrifugal pump, and its bearing flow is too large; the export valve should be closed to reduce the flow of the pump.

(7) The viscosity and density of the process medium exceed the target value; solution: the material composition should be verified to ensure that the viscosity and density are similar to the design value.

(8) The centrifugal pump starts the process of opening the export valve all the way, and the resistance in the export pipe is very small; Solution: close the export valve, and slowly open the export valve after the centrifugal pump starts.

(9) The balance pipe is not smooth; treatment: unclog the balance pipe.
