 Sewage submersible pump, BQW-11KW mine explosion sewage submersible pumps The company specializes in the production BQS (BQW) series mining flameproof submersible flushing pump, BQS sediment flameproof submersible sewage pump, BQS30-70 -18.5 series flameproof submersible flushing pump, BQW series of mining flameproof submersible pump sediment, sediment flameproof submersible pump, flameproof submersible pump such as a sediment 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) life 5 to 8 times longer. 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 of conditions 1, 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. Third, the model shows four, technical data BQS flameproof submersible pump performance table model sediment flow m3 / h Head m power kW synchronous rpm r / min Overall dimensions mm diameter outlet pipe diameter mm high × weight kg BQS 12-20-2.2 / N (MN) 12 20 2.2 3000 40 510 × Φ225 44 BQS20-15-2.2 / N 20 15 2.2 40 510 × Φ225 44 BQS 10-28-2.2 / N 10 28 2.2 40 510 × Φ225 44 BQS15-22-2.2 / N 15 22 2.2 40 510 × Φ225 44 BQS 25-12-2.2 / N 25 12 2.2 40 510 × Φ225 44 BQS 12-20-3 / N 12 20 3 50 540 × Φ225 47 BQS15- 35-4/NK 15 35 4 50 500 × Φ320 90
