QYW25-70 type wind-driven flushing sewage submersible pump 
 BQF-Ⅳ pneumatic submersible pumps, FWB35-20 wind-driven submersible pump, QYW QYW20-25/70-60/100-36/25-45/25-70 type of wind-driven water submersible pumps, QYQ type high lift pneumatic Diving pump, BQW type Mine explosion-proof submersible sewage pump 
 Use and maintenance 
 1. In the use of this new pump is required before a test run on the ground, air pressure in the 0.4 --- 0.5i 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. Into the fabric of rubber gas hose 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. To open the pump before the oil mist to be filled inside the oil, adjusted the valve as required. Course of their work, each class should be required to oil mist or HJ20 HJ10 injection machine oil again. Not the case in the absence of oil operations, but also Wang alternative to grease. 
 5. Impeller nut must be padded washers to prevent the rotor upside down when the back loose, causing subsidence and pump impeller friction. 
 6. In the replacement blades and other vulnerable parts of the ring assembly and disassembly process, can not use a heavy hammer blows, so as not to damage 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. The wind speed is high the pump, by air, water cooling, not for a long time to load operation, the internal parts to avoid burning fever. 
 8. Sewage air pump in the sand with rock dust to use more Cho, through <= 14mm particles, not because of the small solid particles or fibers inhaled and congestion, will not result in inhalation and medium grain prematurely. 
 9. Exhaust pipe should be above water, not water from the exhaust pipe of the other impurities, the cylinder internal parts to avoid corrosion or leaves the rotor stuck. 
 10. Air pump, such as long-term storage should be cleared of demolition, oil seal coated to prevent corrosion of internal parts.
