BQW30-22-5.5KW Flameproof flameproof submersible pump sewage submersible sewage - Mine pneumatic submersible pump-BQF-Ⅱ pneumatic submersible pumps BQS series flameproof submersible flushing pump be pumping sewage containing solid particles without affecting the efficiency with ordinary water pump (pumping water) extend the service life of 5 to 8 times. Compared with similar products have a smooth start, low noise, safe and reliable, long life and other characteristics, especially in the drainage process, if the water supply interruption, the pump can continue to operate by its own unique structure can be air cooled motors. Therefore, the pump is not burned idling motor without compromising the water pump, water can continue after the water automatically. The pump is suitable for a methane explosion hazard environment, drainage sewage containing solid particles, coal mine shaft, shaft construction and drainage, water storage pit mine main drainage, mining face drainage, main shaft bottom coal bunker automatic withdrawal drainage, old pond, no man's land gushing automatic drainage, water storage and drainage, desilting sand drainage, drainage relief and rescue. Mine explosion-proof submersible sewage pump consists of motor, pump part and the seal oil chamber composed of three parts. Motors are explosion-proof structure, B class insulation, winding maximum allowable temperature 130 ℃. Sealed motor oil chamber located below the axis of the rotor is equipped with one pair of mechanical seal, oil chamber Note 10 engine oil, oil drain plug seal chamber sidewall. In part by the impeller pump, water pump and base composition, coaxial pump and motor for the pump structure. BQW type Mine flameproof submersible sewage pump and suitable for use in methane and coal dust explosion hazardous areas with sewage water properties, can be used in any work surface coal mine, transport with dirt, coal, sand, etc. ground solid particles.
