1.For the self suction pump:
Should be placed in a better place to run, in order to facilitate the rapid heat dissipation, reduce motor temperature. Otherwise, a long time to run, very easy to burn the motor. Such as farmers in the use of a pump, the cover removed because there is no plastic film on the motor, resulting in motor overheating and burned the coil. In addition, before, we must check the pump body of water, otherwise, not only affects the self absorption properties, and easily damaged seal parts. Under normal circumstances, 3 to 5 minutes after the start of the pump should be water, otherwise it should be immediately shut down inspection.
2.For submersible pump:
To do the necessary checks before the start of the submersible pump: the rotation of the shaft is normal, there is no blocking phenomenon; the location of the impeller is normal; cable and cable plugs broken, bruised and broken phenomenon. The operation should pay attention to the observation of the voltage change, the general control within the rated voltage of + 5%. In addition, the water pump in the water is very important, the election should be abundant in water, mud, water quality good, suspended vertically in the water, not across, into the mud to avoid clogging the pump or suspension of imports, and cause a sharp drop in water or even no water to.
3.Pump maintenance ：
When the pump once there is a failure, do not have their own demolition. Because of their demolition, one is not aware of where the failure caused by blindly indiscriminate demolition of a pass; two is no special tools and often damage the original integrity of the parts. The best way is to repair maintenance experience, scale, and timely replacement of "overage" and certain parts of vulnerability. Under normal circumstances, the pump should be maintained once every six months, to eliminate the disease with the disease. Tenfu shears.
4. Non use period stored ：
In the non - use period, the pump should be put away from the water, and emptying the pump water, especially in the cold winter. Then place it in a dry place, a condition of the user can also be coated with butter in the key parts of the pump, in the bearing with lubricating oil, in order to prevent parts rust. In addition, the pump is not used, not the longer the better. If not used for a long time, not only is extremely easy to rust parts, but also reduce the life of the pump.
