Slurry pump static and dynamic friction or stuck judgment

1. When there is abnormal noise in the pump casing of the slurry pump, the disc brake will hear friction sound after stopping. It can be judged whether the clearance in the pump is too small, the back cap of the impeller is off or the foreign matter in the pump causes friction, so that the external load is increased. Disassemble the check to determine the specific site.

2. For the double-support slurry pump, when the impeller block is seriously corroded, it will cause the impeller to move axially and rub against the pump casing to increase the load; this situation can hear the friction sound in the pump casing, and sometimes There is a crash sound and the operating state is unstable.

3, the bearing box has abnormal sound, bearing damage, resulting in holding the shaft, the pump does not run, the motor trip or bearing clearance is small, but also make the load increase.

Then, for pump assembly is not good, the part of the static and dynamic friction or stuck method is to reassemble the pump.

4, touch the balance tube by hand, the temperature is lower than usual, indicating that the balance tube is not smooth, resulting in increased balance disk friction.
