The grooves on the Submersible Sewage Pumps Manufacturers to protect the cables must not have burrs or sharp corners. ②The cable connector should be immersed in water at room temperature for 6 hours. Measured with a 500V voltmeter, the insulation resistance should not be less than IOOMQ. ③After the stator winding of the wet submersible motor is immersed in water or oil at room temperature for 48 hours, its insulation resistance to the casing shall not be less than 40MD. ④The well-used submersible pump should meet the following requirements when assembling: when assembling the pump, the pumping pipe, and the drive shaft
, the well pipe orifice should gradually extend into the well at the corresponding level of the foundation after the connectors are tightened, and the submersible pump cable should be firm The ground is tied to the lifting pipe; when the threaded lifting pipes are connected to each other, the threaded part should be lubricated and should not be filled with hemp or lead wire. The end of the pipe should be attached to the bearing bracket or the two pipes should be directly attached.
The depth of the inlet connector should be equal, and the tightening torque of the bolts of the flange-connected pumping pipe should be even; after the coaxiality of the shaft and the pumping pipe is adjusted, the bearing body should be installed, and every 3 to 5 sections of the pumping pipe should be connected.
Afterwards, check the rotating part. The rotation should be flexible. The assembly of the long shaft deep well pump should meet the following requirements: When the drive shaft is connected by a threaded coupling, the two shaft ends should fit tightly, and the depth of the two shafts screwed into the coupling should be Equal; the pump base should be placed on the foundation after being connected with the pumping pipe.
