Troubleshooting Method for Special Pump of Press Filter

- Apr 27, 2019-

The special pump of filter press is the heart of the filter press. No matter what kind of filter press, the special pump of filter press is a very important part. It can be said that the special pump of filter press affects the working efficiency of the filter press. If the special pump of filter press breaks down, it will be very troublesome.


1. First of all, when the special pump of filter press fails to pump out the liquid, there is air in the suction pipe to re-infuse the liquid. The suction pipe leaks air. Check the suction pipe. The liquid in the pump is insufficient to re-infuse the liquid. The suction pipe is blocked by debris to remove the blocked debris.   

 

2. If the pump reverses, adjust the steering.

 

3. If the suction height is too high, the installation height will be reduced.

 

4. The insufficient flow is due to the damage of impeller and the replacement of impeller.

 

5. Insufficient rotational speed, check motor and power supply lines, there are impurities blocked in the pipeline, remove the blocked impurities, the power is too large, filter press manufacturers often meet this point.

 

6. Reducing viscosity or increasing pouring pressure by excessive conveying medium proportion

 

7. The error between the axes of special pump and motor of filter press is too large, so it should be readjusted.

 

8. Insufficient lift, air in conveying medium, re-infusion of liquid or exhaust air

 

9. Loose clamp of special pump for filter press, adjust clamp screw

 

10. The suction height is too high to cause cavitation and reduce the installation height.

 

11. Wear of dynamic and static rings of mechanical seals, low spring pressure, replacement of wear materials and adjustment of springs

 

12. If the dynamic and static rings of mechanical seals do not fit well, adjust the dynamic and static rings.
