In the above, we explained that after the high and low temperature damp heat test chamber compressor card cylinder can be used to solve the fault by the capacitor start method and the tapping method, what methods can we deal with in addition to these two methods? ?
Third, the air pressure method
The compressor was separately removed, and a 0.1 MPA reaction force was applied to the compressor from the high pressure pipe with nitrogen. The loose shaft mechanism is loosened. Rinse for 5 minutes. Then use the above method.
Fourth, the pressure relief method (also known as decompression method)
Let the Freon be put out to reduce the pressure, and then use the above method for comprehensive utilization.
Five, three-phase power start method
If the above does not work, the three-phase power supply starting method can be used. The connection method is that the N connection CR and the S are connected to different phases of the live line. Plug in for a short time to start within 6 seconds.
Sixth, the lubrication method.
Usually, there is a scale inside the compressor, or a card cylinder caused by dirty things. The above does not work. The compressor is removed and the oil is poured out. Add kerosene, then pour it out, once in a row, the purpose is to clean the dirty things inside. After washing, put the compressor upside down for 12 hours, pour the kerosene and volatilize it. Then add No. 25 refrigerating oil, pick up the compressor and then a few times on the ground to loosen the parts. Start again with the above method
After the repair is OK, add the frozen oil, the effect will be much better.
The above several methods are flexible and can be repaired by many high and low temperature damp heat test chamber compressors, provided that the resistance of the compressor is normal.
