BQSMining explosion-proof sewage and sand discharge submersible pumpProduct Introduction:
The BQS series explosion-proof submersible sand discharge electric pump for mining has explosion-proof performance, which can meet the drainage needs of underground mining faces and hazardous areas with methane or coal dust in the air, and adapt to the ultimate development direction of hydration and automation before mine drainage. The vulnerable parts and mechanical seals of the submersible sand removal electric pump are made of high hard alloy, which greatly extends the service life of the entire machine.
BQS submersible pump product features:
1. The structure of the electric pump is a single machine single suction centrifugal pump, which adopts a dry high-efficiency motor, a double-layer shell, and an internal structure.
2. The structure of the water pump adopts a single-stage centrifugal impeller and a center symmetric multi expansion chamber pump body. This structure can balance the radial force of the pump shaft, reduce hydraulic impact, and extend the service life of the bearings. The electric pump is equipped with a row of sand holes at the bottom of the water pump, which can balance some axial forces and discharge sediment to avoid clogging the impeller when the pump is stopped for flushing.
3. The cooling method of the electric pump is: the heat generated by the motor is cooled by the cooling airflow inside the iron core and motor housing, and then forcibly cooled by the water flow and airflow (during no-load operation) flowing between the motor housing and the guide housing. This method can ensure that the electric pump runs idle for a long time and overloaded for a short time without burning the motor.
4. The electric pump adopts a sealing form combining skeleton oil seal, hardware alloy double channel mechanical seal and oil chamber. Practice has shown that this type of seal has high reliability and service life.
5. The electric pump has a simple structure and is easy to maintain.
