Maintenance of construction machinery is an important content in use, and also a principle that must be observed. For submersible pumps produced by Zhejiang Pump Industry, there is no exception. So what maintenance does the submersible pump need to do? This is the key point of Xiao Bian today.

First, the installation of leakage protection device, also known as life saver, is also well understood; After all, submersible pumps work underwater, so electric leakage is a very easy problem, and even electric shock accidents occur from time to time; Such a life protector can automatically cut off the power supply when the current is too large. Only timely power off can quickly reduce the danger and ensure safety.

Second, do not start the machine when the power supply voltage is abnormal to avoid dangerous accidents; Before starting the operation, the staff shall observe the voltage value at any time.

Third, avoid frequent switching. When the electric pump stops, it will generate current. If it starts immediately, it will easily lead to excessive starting current and burn out the winding.

Fourth, it is forbidden to overload the submersible pump for a long time. It is not advisable for every kind of construction machinery to work for a long time. The dewatering time of the electric pump should not be too long to avoid overheating and burning of the motor.

Fifth, check whether the rotation direction of submersible pump motor is correct to avoid damage to the motor due to reverse rotation.
