Time node of compressor refrigeration oil replacement 1. The long-term operation of the entire refrigeration system, after the initial maintenance, if there are no special circumstances, the compressor refrigeration oil should be replaced when the refrigeration system working time reaches 10,000-12,000 hours. This is mainly the routine maintenance of the compressor and the entire refrigeration system. 2. If the refrigeration system fails; Such as: the compressor needs to be replaced when the refrigeration motor burns out. In this case, when the cumulative working time of the compressor reaches 80-100 hours, the refrigeration oil needs to be replaced. 3. The internal cooling unit uses aluminum exhaust pipes instead of chillers. In this case, the refrigeration oil needs to be replaced after a hundred hours of operation. 4. This situation belongs to the situation where the entire refrigeration system is fully working.
Under normal operation, observe the cleanliness of the refrigeration oil in the refrigeration system. The intuitive method is to observe whether the refrigeration oil is clear and whether there are impurities in it causing the refrigeration oil to be cloudy. If there is serious turbidity, the freezing oil needs to be replaced in time. Otherwise, the entire refrigeration system may be damaged.
