BQS Mining Sand Discharge Pump Explosion proof Submersible Pump Explosion proof Sand Discharge and Sewage Submersible Electric Pump

Description :

　　1. Pump body and impeller: Based on actual testing, carefully select and match the pump body and impeller to ensure good non clogging, high flow capacity and efficiency, flat power curve, and no overload. The impeller is stable, with minimal vibration and smooth operation.

　　2. Motor: Specially designed submersible motor, IPx8 protection, F-class insulation allows for temperature rise. Under normal temperature rise conditions, the motor edge life is extended, while the submersible cooling effect is good, with low actual temperature rise and long motor edge life.

　　3. Motor cooling: External electric pump: The heat generated by the motor is generated through the casing. As long as the medium submerges half of the motor stator casing, the pump can operate reliably. The more submerged it is, the more favorable it is for motor cooling. Interior mounted electric pump: The electric pump adopts a sandwich strong cooling structure, even if the motor

　　Air freight operation, the temperature rise of the motor can also be controlled below 40 degrees Celsius, greatly improving the service life of the whole machine. It is suitable for places with shallow water levels. The product can be air freight operated for a long time without water, and can be used in unmanned environments, reducing labor costs.

　　4. Shaft seal: The motor shaft seal adopts two independent series connected mechanical seals to form two reliable sealing lines. One is in the medium inside the pump, and the sealing surface is pressed tighter with the increase of medium pressure, effectively preventing water from entering the oil chamber. The second is in the oil chamber, preventing oil from entering

　　In the motor, if one circuit fails (its working conditions are better than the second circuit), the second circuit can still prevent oil and water from entering the motor. The corrugated tube type machine seal combined with innovative structural cavity improves the reliability of the shaft seal, and under normal use, the fault free operation time exceeds

　　Over 2000 hours

　　5. Oil chamber: The oil chamber is a barrier that prevents the medium from entering the motor from the pump shaft. It prevents the medium from entering the motor. If one of the seals leaks, the buffer medium in the oil chamber cannot directly enter the motor. At the same time, it lubricates and cools the friction surfaces of the two independent seals to ensure their reliable operation. However, it can still take away the medium

　　The heating of the lower bearing and some heat from the motor.
