Check the installation size of motor and pump installation size is in line with the!

Check the installation size of motor and pump installation is in accordance with the size, the motor power. Check whether the power supply voltage, frequency, consistent with the motor nameplate, if they are used in the control cabinet and motor matching. Generally cooling way is water cooled. Whether the internal cooling, cooling or web of inside and outside double water cooling method, need water as a medium to cooling heat dissipation of the submersible pump. Submersible pump run idle, no water to winding of submersible pump, such as bearing heating parts for cooling, so do not allow the submersible pump idling. Check whether there is any damage on the power cable, the choice of specification is reasonable, and the cable into the water 6 hours, with 500 v insulation resistance meter measuring the ground insulation resistance shall be not less than 500 ohms. ( Single refers to the joint part of the insulation resistance of water) Submersible pump of internal and external double cooling effect is better, the cooling system of water-cooling submersible pump inner cavity filling water, the stator core, stator winding and rotor winding, rotor core ( The conducting bar rotor and rotor end ring) All immersed in the water, directly by the water cooling machine. Motor stator iron loss, the stator slot winding resistance loss and the end part of the winding resistance loss directly by heat generated by the stator iron core, the casing to the cooling water flows through the surface of the casing. Submersible water pump in water treatment industry is an essential tool, the stand or fall of submersible pump, not only has something to do with the price of high and low, everyday use also determines the longevity of the submersible pump! Submersible water pump work is that the entire water pump and motor in the liquid, effective maintenance of submersible pump to ensure the life of the submersible pump. To aerial installation of submersible pump, cable, power cord don't be too long. Submersible pump in the water or put forward do not make the cable force, lest cause the power cord rupture.
Getting doesn't have to be expensive, time-consuming, or difficult. It all comes down to the right method and a winter cover pump submersible pump in place.
