 A performance overview 
 BQS series flameproof submersible flushing pump impeller press the "two-phase flow" design principle, can contain solid particles of the sewage pumping without affecting the efficiency, compared with ordinary water pump (pumping water) to extend the service life 5 8 times. Compared with similar products have a smooth start, low noise, safe and reliable, long service life, especially in the drainage process, if the water supply interruption, the pump may continue to operate by its own unique structure to the cooling air-cooled motor. Therefore, the water 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 in the environment, drainage water containing solid particles, coal mine shaft, shaft construction and drainage, water storage bottom of the main mine drainage, mining face drainage, withdrawal of the main shaft bottom coal storage automatically drainage, the old pond, no man's land gushing automatic drainage, water storage and drainage, desilting of sand drainage, relief and rescue drainage. 
 Second, the use 
 1, the water conditions: water temperature no higher than 40 ℃, the water's PH value 4 ~ 10, media and severe than 1300kg/m3, medium sand content of less than 20% (weight ratio). 
 2, the installation forms: vertical. 
 3, the electrical work: continuous (SI) operation. 
 4, into the water depth (the submersible pump bottom plane as the base) is not greater than 2m.
