How to find out the cause of submersible acid pump failure from luolintec's blog

When the motor part of the submersible acid pump fails, it should be repaired according to the following methods:

1. There is no response after turning on the power. Most are caused by the short circuit of the power plug, the power lead and the motor winding.​​

2. It is difficult to start or cannot be started, and it is accompanied by a "humming" sound. During maintenance, you can use a small bamboo piece to quickly turn the fan blade according to the running direction. If the motor runs quickly, it means that the starting capacitor or the starting winding is damaged, and the capacitor of the same capacity should be replaced or the starting winding should be repaired; if the motor is stuck, it is mostly the motor and the pump head. mechanical failure, such as bearing damage, impeller stuck, etc.​​

3. The motor can run, but the speed is slow, and the casing is overheated and has a burning smell. Most of them are caused by the short circuit of the motor winding. The motor should be disassembled and repaired by welding, jumper, isolation, rewinding and other measures depending on the damage. 4. Large noise and vibration during operation. In most cases, the bearing is damaged or the bearing and the casing are not properly matched. The motor needs to be disassembled for inspection. If the bearing is damaged, it should be replaced. The worn parts of the motor shaft are treated with chisel, and if the wear is serious, the method of surfacing and then turning is used to repair.

When the pump head part of submersible acid pump fails, it should be repaired according to the following methods:

1. The motor runs normally but the water output is small or not at all. In this case, you should first check the seal of the water pump. When checking, you should first unplug the power plug, block the suction port with your hands, fill the water pump with water, hold the outlet with your mouth and blow hard, and observe whether the pump head leaks or leaks. This is where the seal is damaged. The common fault parts are the suction pad, the outlet pad, and the impeller cover pad, which should be replaced during maintenance. If there is no phenomenon of full water, it is mostly the impeller damage, the water barrier between the suction chamber and the water outlet chamber is corroded, the water barrier of the pump head is flat, the gap between the impeller and the pump casing is increased, etc., the impeller and the pump casing should be replaced. . When replacing the impeller, care should be taken to completely remove the remaining copper blades in the pump to avoid damaging the new impeller again.​​

2. The chassis is electrified. Most of the damage is caused by water seal damage. Water penetrates into the motor through the motor shaft to deteriorate the insulation performance of the motor. It can be repaired by replacing the water seal and drying the motor. It should be noted that because the pump is in contact with water for a long time and works in the open air, it is very easy to get wet and cause the deterioration of the insulation performance. In order to ensure personal safety, the electric submersible acid pump should be reliably grounded.
