How to repair multistage pumps

How to repair multi-stage pumps? In the actual pump process according to the different fault has a corresponding way of handling, the correct grasp of common fault repair method can effectively improve the stability of working conditions, and for the prevention of failure also has important significance, in order to ensure the user's pump experience, in the pump industry to accumulate common faults and the corresponding repair method to provide advice for reference.

About how to repair the multistage pump, common failures and corresponding maintenance recommendations are as follows.

1, multi-stage pump can not be turned on: check whether the motor and power supply are connected properly, and then check whether the pump has a card main or other auxiliary equipment problems, etc. If the pipe pump is stuck to check the coupling to see whether it is normal, if necessary, the pump can be dismantled to check. In addition, you can consider the pump body media pressure is too large, you can try to relax through the exhaust procedure.

2, multi-stage pump flow reduction: pump cavity with air inhalation resulting in abnormal pressure affecting the flow, the need for proper exhaust. In addition, it is also necessary to check whether there is a foreign body winding blockage within the impeller, the rotor part of the serious wear and tear, etc., the need for targeted cleaning and unblocking, and as needed to replace the seal ring.

3, multi-stage pump completely does not absorb liquid: first comb from the operational side, the stone because no irrigation pilot water or irrigation volume is not enough to cause, in addition to re-flooding should also check whether the bottom valve has leaks, while checking whether the pipeline and instrumentation connection is leaking, the pipeline arrangement is too long and other positions. In addition, if the installation position is too high, more than the suction range of the pump type itself will also lead to this problem, need to reduce the suction height.

4, multi-stage pump running power is too high: in the running process, if you find a long time consumption of power is high, you need to check whether the filler is too tight, and accompanied by heat, if there is a need to properly relax the pressure of the material, in addition to check whether the rotary body and shell collision friction, need to be adjusted in a timely manner, and check the wear and tear of the bearings, as required repair or replacement.

In summary, the introduction of multi-stage pump how to repair, common causes and corresponding treatment as above, but also through regular maintenance to do preventive treatment, if interested in knowing more such as screw pumps, pipeline pumps and other information, can continue to focus on zhaoquan pump industry.
