BQW electric submersible sewage pumps for mining 

 BQW (original BQK) type mine explosion-proof submersible sewage pump by the motor, pump parts and seal oil chamber of three parts. Flameproof motor structure, B-class insulation, the maximum allowable winding temperature 130 ℃. Seal oil chamber located in the motor below the axis of the rotor with a pair of mechanical seals, oil chamber 10, oil injection, oil seal drain plug cavity wall there. 
 In part by the impeller pump, water pump and the base composition of coaxial pump and motor for the pump structure. 
 Pump motor part is a thermal protection device, when exposed to water, when the temperature exceeds 75 ℃ automatically cut off power to stop work, get the cooling pump automatically after power has effectively guaranteed submersible sewage pump life. Pump and a small size, compact structure, safe and reliable, move, dismantle, easy maintenance, high efficiency, good performance and low power consumption characteristics than comparable pumps. 
 BQW (original BQK) type mine explosion-proof submersible sewage pump and suitable for use in methane and coal dust explosion hazardous area use sewage water properties can be widely used in surface coal mine in any operation, transmission contains dirt, coal , sediment and other solid particles groundwater.
