Key points for safe use of submersible pumps

Submersible pump compact and lightweight, in rural areas play an important role in production and life, should pay attention to the following points in use.
First, the purchase of submersible pumps should pay attention to its model, flow and lift. If the specifications used inappropriately, will not be able to get enough water, can not play unit efficiency.
Second, install the submersible pump, the cable should be overhead, the power cord should not be too long. Submersible pumps do not sink into the mud, otherwise it will lead to bad heat and burn the motor windings.
Third, try to avoid the boot at low voltage. When the voltage is too low, the motor speed will drop. If it is less than 70% of the rated speed, the centrifugal switch will be closed and the starting winding will be closed Power for a long time to heat or even burn the windings and capacitors.

Fourth, do not allow long-term overload pump operation, do not pumping large amounts of water, dehydration pump operation time should not be too long, so as not to overheat the motor and burned.
Fifth, usually more than check the motor, found under the crack, rubber seal ring damage or failure, etc., should be promptly replaced or repaired to prevent water penetration into the machine.
