BQS (W) mine explosion-proof sewage and sediment submersible pump is a combination of pump and motor power irrigation and drainage equipment, beautiful appearance, simple structure, good sealing performance, stable performance, long life, easy installation and use, and can Long-term continuous operation under water, is widely used in coal mine shaft, inclined shaft and bottom of loose coal slurry drainage automatic drainage. Built-in electric pump, the water flow through the motor sandwich, effectively extending the service life of the pump; External pump, impeller using double flow passage over-current structure, smooth operation, sewage capacity, anti-winding, And a small size, light weight, easy to carry features. Structural features: BQS (W) series mine explosion-proof sewage and sediment submersible pump strictly according to the coal industry standard MT / T671-2005 "coal mine Flameproof Submersible Pump", the Republic of China national implementation of the standard GB3836-2000 "Explosive gas environment with electrical equipment," design and production, the use of Y-type dry flameproof three-phase asynchronous motor, with a large starting torque, good running performance, low noise, small size, light weight, easy maintenance and so on Excellent flameproof structural performance and high degree of protection, suitable for containing methane or coal dust and other explosive gas environment, there is an explosion of mining underground mining face and roadway and other places supporting the use of pumps. Electric pump adopts O-shaped rubber seal as static seal, good structural performance, rubber vulcanization curve control technology to ensure the O-ring moisture resistance and aging of the quality and sealing performance. Dynamic seal with two sets of mechanical seals, and oil compartment isolation protection, effective for rotating friction pair to provide lubrication, the formation of fluid film lubrication protection, while releasing the accumulation of heat during exercise, thus extending the life of the mechanical seal to ensure that The sealing performance. Pump fluid components made of wear-resistant alloy cast iron, the pump part of the fluid mechanical design and balance of technology, effectively extending the service life of the pump.
