Lubrication method for air conditioner compressor fault maintenance

Lubrication method for air conditioner compressor fault maintenance The specific conditions of the lubrication method for air conditioner compressor fault maintenance are as follows: 　　 1. Disassemble the outdoor unit shell and measure all parameters normally. The above five methods did not work. Finally, the air conditioner compressor was removed and the oil in the air conditioner compressor was poured into black and red; 　　 Second, fill the kerosene from the high-pressure outlet and low-pressure suction port of the air-conditioning compressor, and then pour it out, repeating 4 times, the purpose is to wash out the varnish and copper oxide peeled off the air-conditioning compressor; 　　 3. After the air conditioner compressor is cleaned with kerosene, turn the air conditioner compressor upside down for 12 hours to control out the kerosene remaining in the air conditioner compressor and volatilize the kerosene; 　　 Fourth, add No. 25 refrigeration oil, you can add a little more at the beginning, after the oil is added, pick up the air conditioner compressor to the hard ground and pier 2-3, make the air conditioner compressor shaft vibration, help start. 5. Connect the three terminal wires of the air-conditioning compressor by the capacitor starting method. The air-conditioning compressor can be easily started and operated, allowing the air-conditioning compressor to run for 1 hour, draining the excess oil in the air-conditioning compressor, and using the water in the air-conditioning compressor. The heat of the air conditioner compressor evaporates itself, and the current measured by the ammeter is 4.4a; 　　 Sixth, reinstall the air conditioner compressor, weld the high-pressure and low-pressure welding ports, pressure test, leak detection, evacuation, add fluoride, the air-conditioner compressor returns to normal.
