The compressor can be called the "heart" of the constant temperature and humidity test chamber. The good and bad of the compressor will directly affect the life of the whole constant temperature and humidity chamber. Therefore, in order to improve the constant temperature and humidity test in daily life. The following six things can't be done for the service life of the box and the safety of the test equipment. 1. It is forbidden to use oxygen to test pressure! It is forbidden to test the pressure of nitrogen without safety valve! If it is used improperly, it will cause casualties caused by explosion. Some users have experienced this kind of problem. I hope that all users will remind the operator in time and take it as a warning. Be sure to follow the normal operating procedures. 2. The compressor cannot be used in a corrosive environment and cannot be used in a flammable and explosive environment. It is forbidden to use inferior refrigerant, R22 is called difluorochloromethane, and inferior refrigerant will add 30% methyl chloride. Monochloromethane has a strong corrosive effect on aluminum, magnesium and zinc, causing irreversible damage to the constant temperature and humidity test chamber compressor and internal components, which eventually leads to complete scrapping of the entire compressor. 3, in order to reduce the moisture in the system when the compressor is running, please use the dry filter to absorb moisture, but you must not use methanol to absorb moisture, because methanol will seriously damage the motor coil, causing the motor to burn. If moisture is absorbed by carbon tetrachloride, it must be replaced within 24 hours. Otherwise, it will form a sticky body into the compressor after being wet, which will damage the parts and cause the compressor to be scrapped. In order to prevent dirt in the system from entering the compressor, please install an air suction filter as much as possible. 4. Never turn off the exhaust valve when starting the compressor. This will cause damage to the compressor and pose a great risk. 5. The main circuit and thermal protection terminal in the compressor junction box, please be sure to use 704 insulating glue (supplied) to seal the insulation, so as to avoid short circuit when the defrosting and defrosting are too much. 6. The refrigerant must be filled from the high pressure valve into the system (the system must be in a vacuum). It is forbidden to fill the intake valve with excess refrigerant when the compressor is running, otherwise it will cause the compressor to slam.
