In the troubleshooting of the wear-resistant submerged pump, what is the reason why the wear-resistant submerged pump does not apply fluid? From the previous experience, the reasons for abnormal liquid injection are often complicated, such as blockage of the suction pipe, incorrect installation height, gas in the pipeline, damage to the internal components, etc., which will cause the equipment to fail to apply liquid. In this regard, you can follow the following steps to repair:
1. Check whether there is a problem with the pipeline, check whether the pipeline is blocked, whether there is gas that has not been completely eliminated, whether there are small cracks in the pipeline, etc.;
2. Confirm the installation height of the wear-resistant submerged pump, check whether the suction height of the pump during operation meets the standard, and adjust the installation position of the pump according to the standard;
3. Check the internal components of the pump, check the wearing parts in the pump one by one, replace the severely aged or worn components, and then pay attention to whether the magnetic coupling can work normally.
After the above-mentioned routine maintenance, you can basically know why the wear-resistant submerged pump does not apply fluid. When using this equipment, in order to reduce the failure rate, there are several precautions that need to be clarified.
1. Avoid cavitation of wear-resistant submerged pump. When installing, the liquid resistance at the inlet pipe should be considered, and the net suction head should be ensured;
2. After the motor is turned on, pay attention to the change of the outlet pressure. If the pressure gauge is unstable and the phenomenon of rapid fall occurs, the exhaust work should be performed again, and then checked. When the pressure is normal, it means that the air is exhausted. After the end, the pressure is still unstable and accompanied by noise, which is the phenomenon of cavitation.
After the above introduction, I believe you also have an intuitive understanding of why the wear-resistant submerged pump does not apply fluid. When using this pump, you must first understand the operation sequence of normal shutdown and emergency shutdown, and continue to pay attention to the suction pressure. The poor value ensures that the abnormality of the pump is detected in time.
