QYW-25-45-type wind-driven water submersible pump 
 I. Introduction 
 In the new QYQ-17-70-type air pump designed based on QYW-25-45-type wind-driven water submersible pump. The pump is beautiful appearance, small size, light weight, flow, flow part of the structure with downdraft, semi-open impeller use HT200 material particles by ≤ 14MM, sewage capacity, not because of the small solid particles or The inhalation of fibers, and plug, will not result in inhalation abrasive medium premature damage. 
 The overall structure of the pump is simple assembly and disassembly and maintenance easy to move, in the presence of gas and coal dust work surface with absolutely safe and reliable, and equipped with advanced exhaust muffler new, greatly reduces the noise level measured ≤ 85DB (A) greatly improved the working conditions underground use. 
 Second, the model representation

 QYW-25-45-type structure of wind-driven submersible pumps and sewage works, use and maintenance can refer QYQ-17-70-type wind-driven submersible pump. 
 Fourth, structure and working principle 
 The pump from the air motor, pump, lubricator, fittings and muffler five parts. 
 1. Air motor parts: the rotor, blade, cylinder, shell, upper and lower cylinder head, cover and so on. There are five uniform rotor radial slot, tank equipped with blades, the upper and lower cylinder covered with a blowing each eye, the wind pump starts, the eye will be high-pressure gas tank from blowing blowing leaves, while a large number high-pressure gas from the main air duct into the cylinder, push blades, driven by the rotor rotation for power. Seal the bottom left in the shell cavity, cavity with a seal to gas, water separated. Seal Juan sealed by spring, and using gas, water pressure, so that the ring up to enhance sealing effect. 
 2. Pump parts: the pump body, impeller, pump cover, pump blocks and other components. Impeller mounted on the rotor shaft, tighten the wheel nut, fitted with pump, pump base, into the water, the rotor drive impeller rotation, the centrifugal force, the water pump pressure into the vortex channel, and along the outlet pipe discharge. 
 3. Lubricator sections: the shell from the oil mist, oil mist, batteries, oil, valves and other components. Lubricator mounted on the top cover, the shell filled with oil. 
 4. Fitting parts: the rapid combination of joints and quick couplings of two parts. Quick combined installed in the outlet connector, and quick couplings are installed in the inlet mouth. 
 5. Muffler parts: muffler is welded by steel plate stamping, installed in the exhaust gas mouth. 
 Fifth, use and maintenance 
 1. Prior to use the new pump should be a test run on the ground. The air pressure is 0.4-0.5 MPa, the open pump about ten minutes, checking operation is normal, whether on the amount of water to meet the requirements to start is flexible. 
 2. Rubber intake hose cloth not less than 25 mm in diameter, working pressure not less than 0.4 MPa, otherwise it will affect the normal work. 
 3. Quick fittings installed, the first joint of the tube and blowing the impurities to ensure the intake of dry cleaning, to avoid impurities into the shell, causing the rotor stuck parts wear or not functioning. 
 4. Pump ago, oil mist to be filled inside the oil, adjusted the valve as required. Course of their work, should be required within each class into the oil mist lubricating oil HJ10-HJ20 once. Not the case in the absence of oil operations, not to grease maintenance. 
 5. Impeller nut must be padded washers to prevent the rotor upside down when the back loose, causing subsidence and pump impeller friction. 
 6. The replacement of wearing parts such as leaves and seals the assembly and disassembly process, which can not hammer percussion, to avoid damaging the internal parts with precision. Usually in continuous use for about fifteen days after the open air pump should be cleaned once, for maintenance. 
 7. High speed air pump, by air, water cooling, not long load operation, the Ministry of internal parts to avoid burning fever. 
 8. Air pump sewage containing rock dust in the sediment used more Cho, through ≤ 14MM particles, not because of the small solid particles or fibers inhaled and congestion, will not result in inhalation of abrasive medium and premature failure . 
 9. Exhaust pipe should be above water, not water from the exhaust pipe and other impurities in order to avoid corrosion of internal parts cylinder or blades, rotor stuck. 
 10. Air pump, such as long-term storage should be cleared of demolition, oil seal coated to prevent corrosion of internal parts.
