QYW25-70 type wind-driven flushing sewage submersible pump air pump main models FWB25-70 pneumatic submersible pumps, QYW20-25/70-60/100-36/25-45/25-70 type wind-driven water submersible pumps, QYQ type high lift pneumatic submersible pumps, BQF wind-driven sewage pumps, BQW submersible sewage pump, use and maintenance 1. use this new pump is required before commissioning once on the ground, air pressure MPa at 0.4 --- 0.5i when pump ten minutes, checking is functioning properly, the water meets the requirements, start is flexible. 2 rubber fabric hose inlet diameter not less than 25 mm, working pressure not less than 0.4 MPa, otherwise it will affect the normal work. 3 quick-change fittings in the installation, the first tube and the joints flush out any impurities, ensuring the intake of dry and clean to prevent debris from entering the shell, causing the rotor is stuck parts wear or not running. 4 open pump, lubricating oil mist inside to be filled, as required, a good tune valve. Work process, each class should be required to inject the oil mist or HJ20 HJ10 machine oil once. In no case shall lubricants operations, but also to grease Wang alternative. 5 impeller nut must be padded retaining washers to prevent the rotor rewind back when loose, causing subsidence and pump impeller friction. 6 In the Replace all seals and other wearing parts blade assembly and disassembly process, can not use a hammer to avoid damaging internal parts with precision. Usually in about fifteen days of continuous use, the air pump should be cleaned once opened for maintenance. 7 air pump speed is high, by air, water cooling, not for a long time no-load operation, in order to avoid internal parts fever burning. 8 effluent air pump can rock powder containing more sediment turbidity in use, by <= 14mm particles, not because of the small solid particles or fibers inhalation clogging abrasive medium will not result in the suction and prematurely. 9 exhaust pipe should be exposed at the surface, not all the water from the exhaust pipe other impurities, in order to avoid corrosion of the internal parts of the cylinder or the leaves, the rotor stuck. 10 air pump, such as long-term storage should be demolished cleared, oiled sealed to prevent corrosion of the internal parts.
