First, look at the difference between the current of the water pump running at this time and the current of normal operation.
1. When it is smaller than the normal operation (basically 2 \ 3 of the normal current), it may be due to impeller wear, check valve blockage on the pump head and other problems;
2. The current is as large as that in peacetime, so it is the leakage of pipe pad, pipe and pump body.
3. If the current is greater than that during normal operation, it can be basically determined that it is the wear of vulnerable parts.
However, if the cable is damaged, the water volume is as large as usual, but the current will become larger. The current of three 380V motors is generally 2.2A.
The above points are the main reasons for this problem. If you have other questions, please contact Yuanxiang mechanical technicians!
