The influence of the commercial refrigeration The influence of the refrigeration compressor
commercial refrigeration The operation of the piston refrigeration compressor When the compressor starts, it changes from the original static state to the motion state. If starting with load, the required current is more than 5 times larger than during normal operation, and the motor and electrical equipment are easily damaged. Therefore, in addition to small refrigeration compressors equipped with large motors, in order to reduce initial investment and waste in long-term operation, we must try to reduce the starting current of the motor.
Piston refrigeration compressors usually have the following methods: One is to install a bypass valve between the suction and discharge chambers of the body, and when the commercial refrigeration compressor starts, the suction and discharge valves are closed and the bypass is opened. Then quickly open the exhaust valve, close the bypass valve, and then slowly open the suction valve to put the compressor into normal operation; the other is that the serialized compressor adopts an energy adjustment device to reduce the starting load. Its structure and principle The previous article has described it.
Single-stage ammonia compressor operation The operating procedures of single-stage ammonia compressor have been basically described in the previous compressor trial operation, and only the work at start-up will be discussed here.
(1) First, look at the workshop records to understand the reason and time of parking. If the compressor is shut down due to an accident or the compressor is regularly repaired, it should be checked for repair and delivery; if the work needs to be stopped, the duty team leader is responsible for driving; if the continuous parking time exceeds one month or the compressor is overhauled, the compressor should be started by the workshop director And the technician commanded.
