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. In addition, we should also clarify the direction of rotation of the motor, some types of submersible pump forward and reverse can be water, but reverse the small amount of water, the current is large, the reverse will damage the motor windings. To prevent submersible pump leakage in the water when working under the accident caused by electric shock, leakage protection switch should be installed.
Second, install the submersible pump, the cable should be overhead, the power cord should not be too long. Do not force the cable when the unit is launching, which may cause the power cord to break. 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. Do not switch the motor on and off frequently. This is because the pump will run back when it stops. If it is turned on immediately, the motor will start to load, causing the starting current to be too large to burn the winding.
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. During the operation of the unit, the operator must keep an eye on whether the operating voltage and current are within the values ​​specified on the nameplate. If not, the motor should be stopped to find out the cause and solve the problem.
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.
