We must ensure that the pneumatic diaphragm pump is always in good running or standby state, so all the buildings installed pneumatic pneumatic diaphragm pump, fire pump, spray pump, booster pump, sewage pump, air conditioning pneumatic diaphragm pump should be managed by the maintenance staff Responsible for the pneumatic diaphragm pump regular maintenance. Pneumatic diaphragm pump maintenance and repair points what? First, life pneumatic diaphragm pump and air conditioning pneumatic diaphragm pump once a week to conduct routine inspection and maintenance, once every six months to conduct a comprehensive maintenance. Second, the fire pneumatic diaphragm pump and spray pump every month, booster pump test run once every February, running time 10-15 minutes, start fire pump at the top of the test fire hydrant outlet jet range of 6M or more, each Six months to conduct a comprehensive maintenance. Third, the sewage pump, submersible pneumatic diaphragm pump once every six months to conduct a comprehensive maintenance. Fourth, the pneumatic diaphragm pump maintenance should be connected with the pump body within 2 meters of the valve, pressure gauge, piping, etc. with the pump at the same time maintenance. Fifth, the maintenance of the pump body 1, check the pump body should be intact, the nameplate intact, clear and clear direction of the water flow direction, Clean and tidy appearance, paint intact. 2, add oil, if the oil discoloration, impurities, should be replaced. 3, check the packing seal, if leakage should be added or replaced asbestos rope filler. 4, coupling coupling bolts and rubber pads if damaged should be replaced. 5, Fasten the base screws and do anti-rust treatment. 6, moving life Pneumatic diaphragm pump and air conditioning pneumatic diaphragm pump due to frequent operations, the bearings should be opened at both ends of the shaft to be cleaned or replaced each year. Sixth, the motor maintenance 1, the appearance of inspection should be neat, nameplate intact, ground wire connection is good. 2, open the motor junction box wire connector, with 500V megger test motor winding phase and phase, the relative insulation resistance value should not be less than 0.5 megohm. 3, the three-phase motor wiring box wiring and connecting pieces should be firm and tight. Seven, the related valves, pipes and accessories maintenance 1, each valve switch should be flexible and reliable, no leakage inside and outside. 2, check valve action should be flexible, no leakage inside and outside the valve body. 3, pressure gauge indicates accurate, clear dial. 4, pipes and accessories look clean and beautiful appearance, no cracks, the paint should be complete without loss. 5, Jog to determine the pneumatic diaphragm pump steering is correct, if correct, should be corrected. Eight, control cabinet maintenance 1, disconnect the control cabinet total power, check the conversion switch, start, stop button action should be flexible and reliable. 2, check the cabinet air switch, contactors, relays and other electrical equipment is intact, tighten the electrical contact wire and terminal wiring screws. 3, clean the dust inside and outside the control cabinet. 4, close the total power, check the power indicator should be normal. Nine, starting maintenance pneumatic diaphragm pump, observe the ammeter, indicating light is normal. Ten, observe pneumatic diaphragm pump operation should be smooth, no significant vibration and noise, pressure gauge indicates normal, the control cabinet of the appliances without bad noise.
