Mine submersible pump process those who do? 1, the cable connector seal In order to prevent the cable leads to the outer circle and the core oil, in addition to sealing the cable leads to the site outside the seal, the lead wire leads and the inner connector sealed with epoxy glue. Lead the cable and the power cable connector is also firmly connected, strictly sealed to ensure the connector insulation, improve operational reliability. 2, bearing in order to ensure the oil-filled motor mechanical seal reliability. Requires the motor rotor axial does not produce movement. To this end, reverse the lower part of the motor installed two different sizes of single row radial thrust bearings, respectively, to withstand the pump up and down axial force generated during operation. The two bearings are pinned with nuts so that the shaft can not move up and down to ensure that the static and dynamic mechanical seals will not break off during operation, resulting in the leakage of oil and the immersion of external well water. 3, packing structure and lean oil protection signal device, in order to prevent well water immersed in the motor inside, maintaining the machine hydraulic pressure is greater than the external water pressure, therefore, in the lower part of the motor with packing device. The device consists of an oil bag, an oil bag jacket, an oil bag gland and a spring. After the motor assembly oiling, the spring is under pressure, the oil bag is filled with insulating oil. Rely on the pressure generated in the spring in the oil pressure within the machine. When the packing device is working properly, only the insulating oil leaks very slowly through the mechanical seal, while the well water can not reversely penetrate into the electric lumens.
