How to exclude the abnormal sound of the sprinkler pump?

For you to analyze the abnormal sound of the sprinkler pump, what is the problem of sound?

First of all, the impeller of the pump is broken or worn too seriously, and the sprinkler pump impeller needs to be replaced. It is recommended to carefully check whether the pump is abnormal, because if the auxiliary transmission shaft connected to the pump and the force extractor fail, it will also cause abnormal sound. For example, if the drive shaft is deformed, or the gear inside the force extractor is broken or the bearing is scattered, it will cause abnormal noise.

The following is the abnormal sound elimination method at the sprinkler pump:

First of all, turn on the sprinkler power extractor to let the pump and drive shaft work, lie under the car to observe whether the drive shaft shakes, and see if the drive shaft has a problem. Secondly, if there is no problem with the drive shaft, remove the drive shaft, open the force extractor, let the force extractor idling, and see if there is no abnormal sound when the force extractor idling, so that you can determine whether the force extractor has a problem. If there is no problem with the take-up and the drive shaft, then there is a problem with the pump.
