BQS(W) mine explosion-proof sewage discharge submersible electric pump is a combination of pump and electric motor. It has beautiful appearance, simple structure, good sealing performance, stable performance, long service life, convenient installation and use, and It has been used continuously for underwater operation for a long time and is widely used in coal mine shafts, inclined shafts and automatic drainage of coal and mud at the bottom of the well. Built-in electric pump, water flows through the motor interlayer, effectively prolonging the service life of the electric pump; externally mounted electric pump, the impeller adopts double-flow large over-current structure, stable operation, strong sewage discharge capacity, anti-winding, no clogging phenomenon, And it has the characteristics of small size, light weight and convenient carrying. Structural features: The BQS(W) series of mine explosion-proof sewage disposal submersible electric pumps are strictly based on the coal industry standard MT/T671-2005 "Explosion-proof submersible pumps for coal mines" and the National Implementation Standard of the Chinese Republic of China GB3836-2000 "Explosive gases" Designed and manufactured for environmental electrical equipment, the motor adopts Y-type dry explosion-proof three-phase asynchronous motor, which has the characteristics of large starting torque, good running performance, low noise, small size, light weight and convenient maintenance, as well as excellent separation. Explosive structural performance and high degree of protection, suitable for use in explosive atmospheres containing methane or coal dust, mines with mining explosions and roadways, etc. The electric pump adopts O-shaped rubber sealing ring as static seal, and has good structural performance. The rubber vulcanization curve control technology ensures the quality and sealing performance of the O-ring for moisture resistance and aging resistance. The dynamic seal adopts two sets of mechanical seals and has oil compartment isolation protection, which effectively provides lubrication for the rotating friction pair, forms fluid film lubrication protection, and releases heat accumulated during the movement, thereby prolonging the service life of the mechanical seal and ensuring Sealing performance. The fluid component of the electric pump is made of wear-resistant alloy cast iron, and the pump part adopts fluid mechanical design and balance technology, which effectively prolongs the service life of the electric pump.
