overview

BQS(BQW)The series of explosion-proof submersible sand discharge and sewage electric pumps for mining (hereinafter referred to as electric pumps) comply with the standardMT/T671-2005Explosion proof submersible electric pumps for coal mines, the explosion-proof type of electric motor used for electric pumps is explosion-proof, The explosion-proof mark is“Exdl ”。 This electric pump is a "down suction" mining pump developed by our company based on sufficient market research, which is driven by a new energy-saving dry-type three-phase asynchronous motorExplosion proof submersible sand discharge and sewage pump.

Product Features

1 BQS(BQW)The upper part of the series mining explosion-proof submersible sand discharge and sewage pump structure is an explosion-proof submersible sand discharge and sewage pump motor, and the middle part is a mechanical dense pump Sealed, the lower part is composed of a pump, an electric motor, a mechanical seal, and a coaxial connection with the pump.

2. The electric pump consists of an impeller, a volute, an inlet section, an outlet, and other parts. The impeller is fixed using a key type and fastened with nuts.

3The electric motor for the explosion-proof submersible sand discharge and sewage pump is a three-phase AC explosion-proof squirrel cage asynchronous motor, and the stator winding is made of polyester enameled wire, Greatly improve the lifespan of the electric motor.

4. The casing of the unit is made of materials such as steel plate and ductile iron, which are small in size, resistant to compression and impact, safe and reliable, and sturdy and durable.

5. The cable entry adopts a special sealing structure, and water cannot enter the interior of the motor. The rubber oil seal of the motor shaft extension can block mud and sand. Seals include dynamic seals and static seals, using integral double end mechanical seals.
