 Wind pumps Model FWB25-70 wind-driven submersible pump, QYW20-25/70-60/100-36/25-45/25-70 type pneumatic sewage submersible pumps, QYQ-type high-lift wind-driven submersible pump, BQF wind sewage pump, BQW sewage submersible pump, 

 Use and maintenance 
 1 new pump in use is required before a test run on the ground, air pressure in the 0.4 --- 0.5i MPa, about ten minutes to open the pump and check functioning properly, the water meets the requirements to start is flexible. 
 2 inlet inside diameter rubber hose cloth not less than 25 mm, working pressure not less than 0.4 MPa, otherwise it will affect the work. 
 3 In the installation of quick-change tube fittings, pipe and fittings will be first at the impurity blowing, to ensure intake of clean and dry, to avoid impurities into the shell, causing the rotor stuck or worn parts can not operate. 
 4 to open the pump before the oil mist to be filled with oil inside, as required, adjusted the valve. Work process, each class should be required within the lubricator or HJ20 HJ10 into a mechanical oil. Not the case in the absence of oil operations, but also Wang alternative to grease. 
 5. Impeller nut must be padded just back washer to prevent the rotor upside down when the back loose, causing subsidence and a pump impeller friction. 
 6 leaves the ring in the replacement of wearing parts such as assembly and disassembly process, which can not hammer percussion, so as not to damage the internal parts with precision. Generally after about fifteen days of continuous use, open air pump should be cleaned once, for maintenance. 
 7 high speed air pump, by air, water cooling, not a long time to load operation, so as not to heat the internal components burning. 
 8. Sewage pumps in the wind with more muddy sediment rock powder used, can be <= 14mm particles, not because of the small solid particles or fibers inhaled and block, will not result in inhalation and abrasive medium prematurely. 
 9. Exhaust pipe should be above water, not water from the exhaust pipe of the other impurities in order to avoid corrosion of the cylinder internal parts or leaves the rotor stuck. 
 10 air pump, if any, long-term storage, should be demolished cleared, oiled sealed to prevent corrosion of internal parts.
