What is BQS mine explosion-proof submersible pump?

BQS mining explosion-proof sand and drainage pump, the full name is "BQS mining explosion-proof sewage and sand drainage submersible pump". In order to meet the drainage needs of underground mining working surfaces in coal mines and places where the air contains methane or coal dust explosion hazards, And to adapt to the ultimate development direction of submersible and automated mine drainage, a new generation of mine explosion-proof drainage equipment was developed. This pump is a new multi-purpose mining submersible pump innovatively designed based on the existing sand discharge pump structure. The implementation standard is MT/671-2005. GB3836 201. The explosion-proof type of the motor is "Exdr". The structural type of the electric pump is The lower part has a downdraft vertical structure with the motor in the upper part. It can be used for long-term diving work or on land. It has the advantages of safety, reliability, high efficiency and energy saving, compact structure, multi-purpose machine, and light weight. It is suitable for normal production drainage and emergency and disaster relief drainage in coal mine tunnel excavation working faces; it can also be used for drainage in coal preparation plants, tunnel engineering water conservancy projects and other places. It is suitable for discharging sewage containing solid particles such as suspended coal powder, rock thickness, coal particles, sand and gravel, and sediment.
