Analysis and Solutions of Three Combined Test Chambers Malfunction Based on the Working Process
In order to found out the reason that return-air overheated in the main preceding refrigeration compressor of three combined test chamber, and for trouble shooting effectively, carried out the analysis and searching fault based on course of work.At first, analyzed and judged the possible reasons that caused overheat base on experiment and common practice, but couldnt determine it, then, inspected the compressor and adjusted valves, but couldnt solve problem yet, finally through efforts and depth profile analysis, the real causes of malfunction were founded: there were some micronic leakage points in one of the manual valves and unloading valve of compressor in the high-pressure part of the system.The freezing medium in the system gradually missed from it on the high pressure line during long time operation, so when the leakage points were handled, the problem is properly settled.In this paper, methods and process of malfunction elimination as well as malfunction features and manifestation of the equipment in every maintenance procedure and the key to the final solutions are elaborated, which hopefully provides reference value and meaning for the maintenance of equipment of the same kind.
