Uses: BQW mine flameproof submersible pump is based on "MT-T671-2005 coal mine explosion-proof submersible pump" "QB / T001-2006 mine explosion-proof submersible sewage pump motor" standard requirements of the design It is mainly used in underground coal mines to discharge sewage containing suspended pulverized coal. It can be used vertically and inclined. It has the advantages of reasonable structure, high efficiency, energy saving, wear resistance, convenient installation and maintenance, reliable use and long service life. Mainly used for coal and plateau mountain water for human and livestock, but also for the city, factories, railways, mines, construction sites for water supply and drainage. Working conditions: motor rated voltage 380V, frequency 50HZ three-phase AC power supply. 2, the transmission medium temperature does not exceed 40 ℃. 3, the transmission of liquid medium PH value of 4-10. 4, the transmission medium in solid volume ratio of less than 0.01%. 5, The density of conveying medium is less than 1.2 × 103Kg / m3 Features: QW deep well submersible pump has the advantages of compact structure, integrated motor and water pump, submersible operation in water, and various status display and protection devices to make the pump run safely and reliably. 1, a unique cable seal design, ruled out the hidden dangers of cable leakage. 2, F-class stator insulation, equipped with thermal protection components. 3, 18.5KW The above pump uses external circulating water to automatically cool the pump to ensure safe operation at minimum water level. 4, the bottom of the motor chamber is equipped with a float switch, the mechanical seal on the motor side of the implementation of custody. 5, in the pump and motor oil chamber is equipped with oil probe on the top, on the pump side of the implementation of mechanical seal monitoring, once the water leakage, the control system will alarm protection. 6, bellows double mechanical seal, sealing material for tungsten carbide, silicon carbide and carbide, to prevent water from entering the motor, to ensure the safe and reliable operation of the motor. 7, Vice impeller used to balance the external pressure mechanical seal to prevent water into the oil chamber, thereby extending the life of the pump. 8, with a replaceable wear sleeve between the impeller and the lower end of the volute to keep the pump running at optimum efficiency. 9. No special requirements for well pipes and pumping pipes (ie, steel pipe wells, gray tube wells and soil wells, etc.); under pressure permission, steel pipes, rubber hoses and plastic pipes can be used for pumping pipes. 10, installation, use, easy maintenance, small footprint, no need to build pump room. 11, simple structure, saving raw materials
