Agricultural submersible pump to buy and use points

Submersible pump compact and lightweight, in rural production and life plays an important role in the use of the following points should be noted.
First, the purchase of submersible pumps should pay attention to its model, flow and head. If the selected specifications are not appropriate, will not be able to get enough water, can not play the efficiency of the unit. In addition, should also find out the direction of rotation of the motor, some types of submersible pump forward and reverse can be when the water, but reverse the amount of water, the current is large, the reverse will damage the motor windings. In order to prevent submersible pump work in the water leakage caused by electric shock accident, should be installed leakage protection switch.
Second, the installation of submersible pumps, the cable to overhead, the power cord should not be too long. Do not allow the cable to force the unit when it enters the water, so as not to cause the power cord to break. Do not sink submerged into the mud, otherwise it will lead to poor heat dissipation and burn the motor windings.
Third, try to avoid the boot at low pressure. The power supply voltage and the rated voltage can not be a difference of 10%, the voltage is too high will cause the motor overheating and burn the winding, the voltage is too low, the motor speed decreases, such as up to 70% of rated speed, start the centrifugal switch will be closed, resulting in start winding Prolonged power and heat and even burn the windings and capacitors. Do not frequently switch the motor, this is because the pump will stop when the return flow, if the boot immediately, will start the motor load, resulting in starting the current is too large and burn the winding.
Fourth, do not let the pump long-term overload operation, do not smoke a large amount of water, the pump dehydration operation time should not be too long, so as not to overheat the motor and burned. In the operation, the operator must observe whether the operating voltage and current are within the values ​​specified on the nameplate at any time. If the motor is not in compliance, the motor should be stopped to find out the cause and eliminate the fault.
5, usually check the motor, such as found under the cover with cracks, rubber seal ring damage or failure, etc., should be replaced or repaired in time to prevent water penetration into the machine.
