Several problems should be paid attention to when using the pump
Properly mastering the use method is an important factor in prolonging the life of the pump and reducing economic losses.
(a) for submersible pumps
Before starting, you should do some necessary checks: whether the rotation of the pump shaft is normal, whether there is any jamming; whether the position of the impeller is normal; whether the cable and cable plug are broken, scratched or broken. Pay attention to the change of voltage during operation, generally within ±5% of the rated voltage. In addition, the position of the water pump in the water is very important. It should be selected in a place with abundant water, no silt and good water quality. It should be suspended vertically in the water. It should not be placed horizontally to avoid falling into the mud or blocking the water pump inlet by suspended solids. This will result in a sharp drop in water output or even a drop in water.
(b) for self-priming pumps
It should be placed in a well ventilated place as much as possible to facilitate rapid heat dissipation and reduce motor temperature. Otherwise, it will be easy to burn the motor when it is running for a long time. For example, when a farmer uses a self-priming pump, the motor is overheated and the coil is burned out because the plastic film covering the motor is not removed. In addition, before starting, be sure to check the water storage in the pump body, otherwise, not only affect the self-priming performance, but also easy to burn the shaft seal components. Under normal conditions, the water should be discharged within 3 to 5 minutes after the pump is started. Otherwise, it should be stopped immediately.
(three) pump repair
When the pump fails, do not disassemble it yourself. Because of the dismantling of oneself, one does not know where the fault is located, causing blind dismantling; second, there is no special tool and often damages the intact parts. The best way is to go to an experienced, large-scale repair point to repair, and replace the "overage" parts and some wearing parts in time. Under normal circumstances, the pump should be repaired once every six months to prevent the "ill" work.
(4) Storage during non-use period
During the non-use period, the pump should be removed from the water source in time and the water in the pump should be drained, especially during the cold winter months. Then place it in a dry place. Conditional users can also apply butter to the key parts of the pump and add lubricant to the bearing to prevent corrosion of the parts. In addition, the non-use period of the pump is not as long as possible. If it is not used for a long time, it will not only easily rust parts, but also reduce the service life of the pump.
