2.2KW explosion-proof submersible pump 
 Explosion-proof submersible pumps, submersible pumps for mining explosion-proof, explosion-proof submersible pump spot 
 Pump used as a static O-ring rubber seal, good structural performance, the use of rubber vulcanization curve control technology to protect the O-ring resistant to moisture and sealing performance anti-aging quality. Dynamic seal uses two sets of mechanical seals, and oil room isolation, effectively turning friction to provide lubrication, the formation of fluid film lubrication protection, while releasing the heat accumulation during exercise, thus extending the service life of mechanical seals to ensure the sealing performance. 
 Pump wetted parts materials with wear-resistant alloy cast iron, pump some fluid mechanical design and balance the use of technology to effectively extend the pump life. Structural features: BQS (W) mine explosion-proof submersible pump sewage sediment, is one of the pumps and electric motor combination of irrigation and drainage equipment, appearance, simple structure, good sealing performance, stable performance, long life, easy to install and long-term continuous operation under water, is widely used in coal mine shaft, slope and drainage bottom loose slime to automation. Built-in pump, water flowing from the motor sandwich, effectively extending the service life of pumps; outside-mounted pump, greater than double channel impeller flow structure, smooth operation, sewage capacity, anti-wound, non-clogging, and small size, light weight, easy to carry features. 
 BQS (W) series mining flameproof submersible pump sewage sediment strict standards MT/T671-20 machine according to the coal industry, with a starting torque, running performance, low noise, small size, light weight, easy maintenance characteristics, and excellent explosion-proof structure, performance and high level of protection, suitable for containing explosive gas such as methane or coal dust environment, risk of explosion of the mine and other mining sites and roadway surface and supporting the use of pumps. 
 Uses: 
 Containing methane or coal dust explosion hazard of coal mine drainage mining face 
 Mine shaft, slope drainage construction 
 Bottom main drain mine water storage 
 The main shaft bottom bulk coal storage automatic drainage 
 Old pond, no man's land gushing automatic drainage
