Five items to pay attention to when using Copeland compressors

Five items to pay attention to when using Copeland compressors 1. Copeland compressors are strictly forbidden to perform pressure test under oxygen, and for nitrogen without safety valve! Improper use will cause an explosion and cause casualties. Some users have already experienced this situation. I hope that all dealers promptly remind the installation personnel and use it as a warning. They must follow the operation process. 　　 Second, the machine should be installed on the horizontal surface through the shock absorber and fixed. The plane should not vibrate or shake violently. The compressor must not be used in corrosive environments, nor in flammable and explosive environments. Chloromethane has a strong corrosive effect on aluminum, magnesium and zinc, which will cause irreversible damage to the compressor and its internal accessories, and eventually the entire compressor will be completely destroyed. 　　 Third, in order to reduce the water in the system during the operation of the compressor, be sure to use a dry filter to absorb moisture, but methanol must not be used to absorb moisture, because methanol will seriously damage the motor coil and cause the motor to burn. If carbon tetrachloride is used to absorb moisture, it must be replaced within 24 hours. Otherwise, a sticky object will form into the compressor after being wetted, which will damage the parts and cause the compressor to be scrapped. In order to prevent the dirt in the system from entering the compressor, please install the suction filter as much as possible. Please use a vacuum pump to vacuum, try not to use the compressor to vacuum. When the oil pump lubricated compressor is used, an oil pressure protection device must be installed, so that the compressor will have a longer life in the operation step. 　　 Fourth, in order to avoid liquid hammer operation, please close the suction valve when the compressor is shut down for a long time, and energize the crankshaft heater 3 hours before starting. Do not close the exhaust valve when starting the compressor. This will cause damage to the compressor and there is a great risk. The main lines and thermal protection terminals in the compressor junction box must be sealed with 704 insulating glue to avoid short circuit due to contact with the wire when it falls off and excessive frost. Fifth, the compressor will shorten the life of the compressor when it is used outside the range. At this time, the superheat should be adjusted. The method of cooling the compressor should be used to run the machine within the specified range. The refrigerant must be added to the system from the high-pressure valve. Note. It is strictly forbidden to add excessive refrigerant from the suction valve when the compressor is running, otherwise it will cause compressor liquid shock, which will reduce the service life of the compressor. 　　Regarding the five points for the use of Copeland compressors, we must pay special attention to the process of our use. Only in this way will it avoid unnecessary problems and thus complete a safe and effective operation.
