(1) The medium conveyed by the vacuum pump is pressed too tightly; Solution: loosen the packing gland of horizontal pump.
(2) The rotating speed of the vacuum pump is too high; Solution: Reduce the rotating speed of the centrifugal pump.
(3) The motor power of vacuum pump is too small; Solution: Adjust the matching motor and replace it.
(4) The bending bearing of the pump is worn or damaged; Solution: Repair or replace the pump shaft alignment bearing.
(5) Maybe something is stuck; Solution: Check whether the outlet and inlet pipes are blocked by foreign matters, and then check whether there is something blocked in the pump.
(6) The actual use head is too much less than the centrifugal pump head, and the bearing flow is too large; Solution: Turn down the outlet valve to control the flow of the centrifugal pump.
(7) The corresponding viscosity and density in the process medium exceed the index; Solution: Check the material composition to ensure that the viscosity is close to the density and the design value, which can be adjusted by the process operator.
(8) When the centrifugal pump starts, all the outlet valves will be opened, and the resistance in the outlet pipeline is very small; Treatment method: close the outlet valve and slowly open the outlet valve after starting the centrifugal pump.
(9) The balance pipe is not smooth; Treatment method: dredge the balance pipe.
