How to repair the air conditioner compressor failure

Pharmaceutical freeze dryer composition system introduction The freeze dryer is also called freeze dryer and vacuum freeze dryer. The pharmaceutical freeze dryer is divided into common type and gland type. Its system software is composed of refrigeration unit, vacuum system software, automatic control system, circulation system and hydraulic system. The following Shanghai Tianfeng Freeze Dryer says the functions and effects of the various system software: 1.Refrigeration system: It is the most critical function position in the vacuum freeze dryer. It is composed of the refrigeration unit and its auxiliary equipment. It can show the cold storage for the drying box and the cold trap. In addition to the display information in the refrigeration unit In addition to the high-pressure and low-pressure barometers, there is a pressure controller. When the high-pressure working pressure is too high, the high-pressure relay will start to work, and then the refrigeration compressor will stop working; 2. Vacuum system: It is composed of many parts such as drying box, cold trap, vacuum gate valve, vacuum pump, vacuum pipeline, and vacuum precise measurement gauge. Among them, the vacuum pump group has strong liposuction work ability, on the one hand, it can promote Moisture is lifted under vacuum. On the other hand, the system software will generate a vacuum pressure difference between the cold trap and the drying oven, which will cause the moisture in the dry tank to be successfully captured by the cold trap after the lift. ; 3. Control system: It is mainly composed of programmable controller program flow control board, touch display screen, field auto relay, controller, etc .; 4. Circulation system: In the vacuum freeze dryer, the circulation system is also an indispensable part. The low temperature drying and heating of the freeze dryer are all a production process that uses the temperature difference to cause the chemical substances to be transferred The cooling and heating of the board are all based on the heat conduction of the high-temperature heat-conducting oil, so that the high-temperature heat-conducting oil can continuously develop the circulation system in all system software, and the shielded circulation system must be shielded to carry out the work; 5. Hydraulic system: It is the power device in the gland-type vacuum freeze dryer, which is mainly used to press the stopper of the vial into the mouth of the bottle when the dryness is completed.
