Refrigerating oil replacement method steps
The compressor is different, and the method of replacing the refrigerating oil is different. This article takes the screw compressor as an example. (Actually, we have published articles on the public account of Refrigeration Encyclopedia before the refueling method of semi-hermetic compressors and scroll compressors, you can look at the previous articles)
1. Recover the system refrigerant to the condenser side, remove the refrigerant in the compressor, and discharge the refrigerant oil from the oil drain angle valve of the compressor.
2. The lubricating oil of the compressor is discharged from the drain valve on the oil filter. When the lubricating oil is nearly exhausted, add a certain amount of nitrogen from the detection joint of the high-pressure end of the compressor, use the pressure to accelerate the lubricating oil discharge, and stop the injection Pressure, close the drain valve. Then remove the oil filter of the compressor, release all the lubricating oil in the oil tank, and then clean the oil filter and install it and tighten it.
3. Add lubricating oil according to the standard amount of the compressor, and evacuate the system at the same time. It is recommended to select high (low) pressure side angle valve or other relatively high point for the contact of the vacuum pump to prevent pumping refrigerating oil from damaging the vacuum pump. When performing vacuum pressure holding or leak checking, observe whether the pressure rebounds.
4. Inject lubricating oil, connect it to the drain valve with a clean plastic pipe, and put the other end of the plastic pipe into the oil drum (the plastic pipe is placed at the bottom of the oil drum). When filling oil, the oil drum should be closed to reduce air pollution to the oil.
