Submersible pumps play an important role in production and life. We should pay attention to the following points when using them.




First, when choosing submersible pumps, we should pay attention to its type, flow and lift. If the specifications are not suitable, it will not be able to get enough water output and the efficiency of the unit can not be brought into play. In addition, we should also know the direction of rotation of the motor, some types of submersible pumps can be reversed when the forward and reverse water, but reversal of water output is small, large current, its reversal will damage the motor winding. Electric leakage protection switch should be installed to prevent electric leakage accident of submersible pump when working under water.
Two. When installing small submersible pump, the cable should be overhead and the power cord should not be too long. When the unit is launched, do not force the cable, so as not to cause the power cord to break. The submersible pump should not sink into the mud, otherwise it will cause bad heat dissipation and burn the motor winding.
Three, try to avoid starting at low voltage. Power supply voltage and rated voltage can not be 10%, too high voltage will cause motor overheating and burn out the winding, too low voltage will reduce the motor speed, such as less than 70% of the rated speed, the start of the centrifugal switch will be closed, resulting in long-term power on the start-up winding and even burn out the windings and capacitors. Do not switch the motor frequently, this is because when the pump stops running, there will be reflux. If you start the motor immediately, the load will start, resulting in excessive starting current and burning out the winding.
4. Do not let the pump long-term overload operation, do not pump sediment-laden water, pump dehydration operation time should not be too long, in order to avoid the motor overheating and burning. During the operation of the unit, the operator must always observe whether the operating voltage and current are within the specified values on the nameplate. If not, the motor should be stopped, find out the cause and troubleshoot.
Fifth, usually check the motor, such as found cracks in the lower cover, rubber seal ring damage or failure, should be replaced or repaired in time to waterproof infiltration machine.
