BQS (W) series mine explosion-proof submersible sewage pump is a combination of pump and motor power irrigation and drainage equipment, long-term underwater continuous operation, is widely used in coal mine shaft, inclined shaft and well At the end of spontaneous drainage slime. Now to introduce mine flameproof submersible sewage pump structure, use and conditions of use. Mining Flameproof Submersible Sewage Pump A mine explosion-proof submersible sewage pump structural features BQS (W) series mine explosion-proof submersible sewage pump motor Y-type dry explosion-proof three-phase asynchronous motor, with a start to turn Large moment of operation, good performance, low noise, small size, light weight, easy maintenance and so on, as well as excellent flameproof structure performance and high protection grade, suitable for explosive gas atmospheres such as methane or coal dust, explosion danger Underground mining face and roadway and other places supporting the use of pumps. Built-in electric pump, the water flow through the motor sandwich, effectively extending the service life of the pump; External pump, impeller using double flow passage over-current structure, smooth operation, sewage capacity, anti-winding, And a small size, light weight, easy to carry features. Electric pump adopts O-shaped rubber seal as static seal, good structural performance, rubber vulcanization curve control technology to ensure the O-ring moisture resistance and aging of the quality and sealing performance. Dynamic seal with two sets of mechanical seals, and oil compartment isolation protection, effective for rotating friction pair to provide lubrication, the formation of fluid film lubrication protection, while releasing the accumulation of heat during exercise, thus extending the life of the mechanical seal to ensure that The sealing performance. Pump fluid components made of wear-resistant alloy cast iron, the pump part of the fluid mechanical design and balance of technology, effectively extending the service life of the pump. Second, the mine flameproof submersible sewage pump uses Contains the danger of methane or coal dust explosion in coal mine face drainage Drainage coal mine shaft, inclined shaft construction Drainage Shaft without water tank bottom hole Main drainage bottom hole loose coal warehouse Automatic drainage Ponds, unpopulated water gushing automatic drainage Coal mine dust, sediment and other smaller solid particles of groundwater discharge Clear water storage drainage emergency rescue urban sewage drainage system environment Third, mine flameproof submersible sewage pump conditions of use Convey Medium temperature should not exceed 40 ℃ Medium containing solid particles, the volume concentration is generally not more than 2% The pH of the transmission medium in the range of 4 to 10 Working environment temperature 0 ~ 40 ℃ Water pump submerged depth of not more than 5m Maximum solids in the medium The diameter is not greater than 50% of the minimum size of the flow passage section of the pump runner Expand to Read: Pumps Valves Tube Fittings Exhibitions Water Expo Xiamen Maritime Exhibition Internet + Forum Yiwu Expo Fair Mold Top Ten Brands 2016 Exhibition Information Industrial Internet (Xiamen) Ltd.
