BQS submersible explosion-proof underground drainage pump 55KW mining explosion-proof submersible pump

Description :

　　6. Bearing: The lower double row angular contact bearing has strong load-bearing capacity and, together with the upper deep groove bearing, forms a reliable support for the motor water pump shaft. It has a large bearing margin for the radial, axial, and other forces generated during pump operation, ensuring smooth operation and long service life of the unit.

　　7. Cable and its sealing

　　The cable adopts MT818.5-1999 flame-retardant cable for coal mines. The core section of the cable is designed for long-term reliable operation at an ambient temperature of 40 degrees Celsius and full load power of the motor. If the motor operates at non full load power or below 40 degrees Celsius during operation, the service life is long.

　　There is a sealed compression between the cable rubber sleeve and the motor cover to prevent the medium from seeping into the motor cavity from the interface between the cable and the motor cover.

　　8. Motor casing: The casing, upper end cover, lower end cover, and other components make up the motor casing. There are reliable static seals at the connection and fitting points of each part. Each unit undergoes strict water pressure testing to ensure that there is no leakage and that everything is foolproof.

　　9. Special handle: There is a dedicated handle for handling, please use the cable as a handle when handling.
