Pneumatic submersible pumps FQW40-20 / W mine pneumatic submersible pumps, the latest offer FQW series of mine pneumatic submersible pumps FQW series of mine pneumatic submersible pumps FQW series of mine pneumatic submersible pump is a self-developed new product development , FQW series of mine pneumatic submersible pump rotor and pump coaxial coupling of mechanical products, with vertical structure, under the pump. FQW series of mine pneumatic submersible pumps are suitable for containing a gas and coal dust explosion hazard drainage work, can be used in any work surface coal mine, transport containing coal, groundwater and sediment particles, the use of safe, reliable and efficient improve air quality field. FQW series of mine pneumatic submersible pumps Technical Features Mine FQW series mine pneumatic submersible pump structure is compact, easy to move, dismantle and repair. Vortex pump hydraulic model of energy efficient road use, the special design of the impeller. The pump sewage water and strong, flow, head advantages. FQW series of mine pneumatic submersible pump structure and working principle FQW series of mine pneumatic submersible pumps are mainly composed of the pump, the gas motor and overcurrent three parts, 1, pump parts: the upper and lower two chambers, in the middle seal the gas and water are separated. Seal with spring seal, and the use of gas, water pressure, high-pressure gas and water respectively into the upper and lower two ring wall, its inner rise, enhanced sealing effect. 2, the gas motor parts: the rotor, turbine, bearings and other components. Powered by compressed air, the impact of the turbine rotor driven at high speed for power. 3, over-current parts: the water wheel, pump cover, suction port, the pump housing and other components. Waterwheel installed in the lower chamber housing a rotor shaft, compressed air from the intake port into the rotor driven turbine operation, the turbine in the water under the effect of centrifugal force, pressed into the housing water vortex streets, along the outlet pipe discharge . FQW series of mine pneumatic submersible pumps Technical parameters FQW40-20 / W mine pneumatic submersible pumps, the latest offer FQW series of mine pneumatic submersible pumps pump Type Rated flow m3 / h Rated head m Working pressure MPa Air consumption m3 / min Quality kg Dimensions mm FQW60-20 / K 60 20 0.5 8 38 610 × Ф450 FQW50-25 / W 50 25 0.5 8 35 462 × Ф347 FQW48-12 / W 48 12 0.5 8 35 462 × Ф347 FQW40-20 / W 40 20 0.5 8 35 462 × Ф347 FQW30-18 / W 30 18 0.5 8 35 462 × Ф347 FQW25-50 / W 25 50 0.5 8 34 462 × Ф347 FQW20-40 / W 20 40 0.5 8 34 462 × Ф347 FQW20-25 / W 20 25 0.5 8 34 462 × Ф347 Fourth, the use, maintenance and servicing a new pump prior to use, to be a test run on the ground. Ground dry run, pressure should be controlled within 0. 2Mpa, test time can not pump more than three minutes, to avoid high-speed operation, increased wear of components, reducing service life. 2, the inlet pipe inner diameter of not less than 25 mm, working pressure of not less than 0. 5MPa, otherwise it will affect the normal work; 3, the installation of the intake manifold, the first will be at the joint and impurities blow tube, ensure the intake of dried clean, avoid impurities entering, causing parts to wear or rotor stuck not operate. 4, be sure to add water wheel nut spring washers to prevent loosening when backwater reverse rotor, resulting in the sinking of the impeller and pump cover friction. 5, in replacement of the impeller, turbine and password shot rings and other wearing parts assembly and disassembly process, can not use a hammer to avoid damaging the internal parts with precision. Usually after about fifteen days of continuous use, open air pump should be cleaned once, for maintenance. 6, wind pumps sewage containing more turbid water and sediment rock powder is used, through ≤7mm particles, not because of the small solid particles or fibers are inhaled and clogging will not result in inhalation of particles of the medium prematurely damage. 7, the exhaust pipe should be out of the water, you can not let the exhaust pipe water and other impurities in order to avoid corrosion of the internal parts of the turbine or the impeller rotor stuck. Fifth, security precautions 1, immediately turn off the gas supply should be dry, stop 12, working pressure must not be greater than 0. 70MPa. 3, found fault should be shut down after the maintenance work. Sixth, transport and storage products using conventional means of transport, transport should be reliable positioning and waterproofing measures to prevent vibration and shock, non rough handling, not with corrosive substances mixed transportation. Products stored in an upright position taken ventilated, dry warehouse, not with corrosive materials in the same storage seven, mine pneumatic submersible pumps 1 safety warnings, installation before using this product be sure to read the product manual, in strict accordance with the provisions of this specification installation and operation. 2, the installation of the intake manifold must be an inner tube and joints flush out any impurities to ensure clean and dry air to prevent debris from entering the cylinder body, causing parts to wear or not to rotate the rotor stuck. 3, the exhaust pipe should be out of the water, we can not let the exhaust pipe water and other impurities, to prevent corrosion of the internal parts or turbine blades, rotor stuck. 4, air pump speed is high (by water cooling), dry load running time can not be more than three minutes! Avoid damage to parts, failure. 5, immediately turn off the gas supply should be dry, stop! 6, the air pressure may not make a big 0. 70Mpa. 7, found fault should be shut down after the maintenance work. 8, the user can not easily replace standard safety kit and principal of zero (yuan) component configuration.
