Make sure the pneumatic diaphragm pump is always in good working or standby state. Living pneumatic diaphragm pumps, fire pumps, spray pumps, pressure pumps, sewage pumps, air conditioning pneumatic diaphragm pumps installed in all buildings. The maintenance personnel of the management office are responsible for the regular maintenance of the pneumatic diaphragm pump. First, the life pneumatic diaphragm pump and air conditioning pneumatic diaphragm pump conducts daily inspection and maintenance once a week, and carries out comprehensive maintenance every six months. Second, the fire pneumatic diaphragm pump and spray pump every month, the pressure pump is tested every two months, the running time is 10-15 minutes, the fire pump starts at the top of the pipe network to test the fire hydrant outlet spray range of more than 6M, each Carry out a comprehensive maintenance in half a year. Third, the sewage pump and the submersible pneumatic diaphragm pump are fully maintained every six months. 4. When the pneumatic diaphragm pump is being serviced, the valves, pressure gauges, pipes, etc. within 2 meters connected to the pump body should be maintained at the same time with the pump. Fifth, the maintenance of the pump body 1. Check that the pump body should be free from damage, the nameplate is intact, the direction of the water flow direction is clear and clear, the appearance is neat, and the paint is in good condition. 2. Replenish the lubricating oil. If the oil is discolored and has impurities, it should be replaced. 3. Check the packing condition of the packing. If there is any leakage, increase or replace the asbestos rope packing. 4. If the coupling bolt and rubber pad of the coupling are damaged, they should be replaced. 5. Fasten the machine base screws and do anti-rust treatment. 6. Living gas pneumatic diaphragm pump and air conditioning pneumatic diaphragm pump are frequently operated. The bearings at both ends of the coupling should be dismantled or replaced every year. Sixth, motor maintenance 1. The appearance inspection should be neat and tidy, the nameplate is intact, and the grounding wire is well connected. 2. Disassemble the wire connecting piece in the motor terminal box, and test the insulation resistance value between the phase and phase of the motor winding and the ground with a 500V megohm meter to be not less than 0.5 megohm. 3. The three-phase wire and connecting piece in the motor junction box should be firm and tight. 7. Maintenance of related valves, pipes and accessories 1. The switch of each valve should be flexible and reliable, with no leakage inside or outside. 2. The check valve action should be flexible, and there is no water leakage inside and outside the valve. 3. The pressure gauge is accurate and the dial is clear. 4. The appearance of the pipes and accessories is neat and beautiful, without cracks, and the paint should be intact without falling off. 5, jog to determine whether the steering of the pneumatic diaphragm pump is correct, if it is wrong, it should be corrected. Eight, the maintenance of the control cabinet 1. Disconnect the main power of the control cabinet and check each switch. The start and stop buttons should be flexible and reliable. 2. Check whether the air switch, contactor, relay and other electrical appliances in the cabinet are in good condition, and fasten the wiring screws of the contact head and terminal of each electrical appliance. 3. Clean the inside and outside of the control cabinet. 4. Close the main power supply and check that the power indication should be normal. Nine, start the pneumatic diaphragm pump after maintenance, observe whether the current meter and indicator light are normal. X. Observe that the pneumatic diaphragm pump should run smoothly, without obvious vibration and abnormal sound, the pressure gauge indicates normal, and the control cabinet appliances have no bad noise.
