BQS (BQW) flameproof submersible flushing pump company specializes in producing BQS (BQW) series flameproof submersible flushing pump, BQS flushing flameproof submersible sewage pump, BQS30-70- 18.5 series flameproof submersible flushing pump, BQW series flameproof submersible flushing pump, flameproof submersible flushing pump, flameproof submersible flushing pump, etc. First, Performance Overview BQS series flameproof submersible flushing pump impeller press the "two-phase flow" design principle, be pumping sewage containing solid particles without affecting the efficiency with ordinary water pump (pumping water) life extension 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. Second, conditions of a water quality conditions: water temperature no higher than 40 ℃, PH value of water 4 to 10, medium and severe than 1300kg/m3, medium sand content of less than 20% (weight ratio). 2, the installation forms: vertical. 3, the motor operating mode: continuous (SI) operation. 4, into the water depth (with submersible pump bottom plane as the base) is not greater than 2m.
