Ways To Prolong The Service Life Of Water Pumps

1. For submersible pumps

Before starting, some necessary inspections should be done: whether the rotation of the pump shaft is normal and whether there is any jamming; whether the position of the impeller is normal; whether the cables and cable plugs are cracked, scratched and broken. Pay attention to the change of voltage during operation, and generally control it within the range of ±5% of the rated voltage. In addition, the position of the water pump in the water is very important. It should be selected as much as possible in a place with abundant water, no silt, and good water quality. It should be suspended vertically in the water, and horizontal placement is not allowed, so as not to sink into the mud or block the pump inlet by suspended matter. As a result, the water output drops sharply or even the water cannot be pumped.

2. For self-priming pumps

It should be placed in a well-ventilated place for operation as much as possible to facilitate rapid heat dissipation and reduce the temperature of the motor. Otherwise, it is easy to burn the motor if it runs for a long time. For example, when a farmer used a self-priming pump, because he did not remove the plastic film covering the motor, the motor overheated and the coil was burned out. In addition, before starting, be sure to check the amount of water stored in the pump body, otherwise, it will not only affect the self-priming performance, but also easily burn the shaft seal parts. Under normal circumstances, the water should come out within 3 to 5 minutes after the pump is started, otherwise it should be stopped immediately for inspection.

3. Pump maintenance

Once the water pump fails, do not disassemble it by yourself. Because when disassembling by yourself, one is blindly dismantling without knowing where the fault is; the other is that there is no special tool and the original intact parts are often damaged. The best way is to repair at an experienced and large-scale maintenance point, and replace "overage" parts and some wearing parts in time. Under normal circumstances, the water pump should be repaired every six months to prevent working with "sickness".

4. Storage during non-use period

During the non-use period, the water pump should be lifted away from the water source in time, and the water in the pump should be empty, especially in the cold winter. Then put it in a dry place. If possible, users can also apply butter to the key parts of the water pump, and add lubricating oil to the bearings to prevent parts from rusting. In addition, the non-use period of the water pump is not as long as possible. If it is not used for a long time, it will not only easily corrode the parts, but also reduce the service life of the water pump.
