The submersible electric pump used in the selection well must be selected according to its purpose. That is, submersible pumps with small flow and high lift should be selected for the pressure tank water supply; the water supply for the water tower should be based on the size and lift of the water tower. Medium-flow submersible pumps; For farm irrigation, in the case of suitable lift, try to choose submersible pumps with large flow. It is also necessary to select the appropriate submersible pump specifications based on the size of the well, the amount of water output, and the sediment concentration. Installation According to the instruction manual, install according to the specified procedures and requirements. In strict accordance with the provisions of the head installation, to prevent low head, the excess flow of the motor overload operation, burning the motor. The depth of installation should generally ensure that the distance from the bottom of the pump to the bottom of the well is not less than 3 meters. When installing the electric pump, ensure that the entire interior of the motor is filled with water. After the electric pump is installed, do not turn on the power immediately. Check the power supply, starting equipment, and instruments used before starting the test. After verifying that the electric pump has been installed, it can be commissioned. After starting, check the voltage and current of the electric pump with the meter, and wait until everything is normal before putting it into work. Before each shift, it is necessary to check the power supply voltage and insulation resistance. After starting up, check the operating current and the operation of the pump. If any problems are found, promptly solve the problem. Do not run the pump in a sick manner. Submersible pumps should not be turned too often when they are started or stopped. They cannot be restarted immediately after shutdown. They must wait until the trapped water in the pipe is completed before starting again. If the submersible pump fails, it is necessary to first check whether there is any problem with the peripheral equipment, such as whether the power supply is normal, whether the well water level drops too much, and whether the pump tube leaks water. Check the pump after pumping out the well. The submersible pump must be completely overhauled for 2 years to replace worn parts. Any maintenance electric pump should be sent to a professional maintenance point for maintenance, and can not be replaced with inferior parts. Submersible pumps that are not used for more than one year should be put out of the well and placed in a dry, non-corrosive room after being overhauled. It is necessary to drain the motor memory water to prevent rust and moisture.
