4inch submersible pump

  It is necessary to find out the rotation direction of the high-quality 4inch submersible pump motor. Now there are many types of submersible pumps that can discharge water during forward and reverse rotation, but the water output is small and the current is large during reverse rotation. winding.

  Cable installation and insulation resistance requirements for high-quality 4inch submersible pump

  When installing a high-quality 4inch submersible pump, the cable should be overhead, and the power cable should not be too long. When the high-quality 4inch submersible pump is launched or lifted, do not stress the cable, so as not to cause the power cord to break. The high-quality 4inch submersible pump should not sink into the mud when working, otherwise it will cause poor heat dissipation of the motor and burn out the motor windings. During installation, the insulation resistance of the motor should not be lower than 0.5 megohms.

  Installation of leakage protector

  The leakage protector is also called a life saver, and its function can be understood from the three words "life saver". Because the high-quality 4inch submersible pump works underwater, it is easy to leak electricity, resulting in power loss and even electric shock accidents.

  Avoid frequent switching

  Do not switch on and off the high-quality 4inch submersible pump frequently. This is because the backflow will occur when the electric pump stops. If it is turned on immediately, the motor load will start, resulting in excessive starting current and burning out the windings. Due to the large current at startup, frequent startup will also burn out the submersible pump motor windings.
