The refrigeration compressors, pipes and valves of supermarket refrigerated showcase work under different pressures. When the refrigerant circulates in the system, due to improper operation, it circulates under abnormal pressure, which may cause accidents. In addition to strictly abide by the operating procedures during the operation of the refrigeration device, the operator must also be protected by more complete safety equipment. Because these safety equipment are the eyes and ears of the operator, some safety equipment can also play a role in automatically troubleshooting.
Therefore, complete safety equipment is a guarantee for the safe operation of supermarket refrigerated showcase, and it is also one of the necessary conditions to prevent accidents. The stronger the ability of the safety equipment to automatically prevent failures, the less likely an accident will occur. Therefore, it is very necessary to set up, improve and perfect the safety equipment of the refrigeration device. For example, the relays that control the oil pressure, suction pressure and exhaust pressure on the refrigeration compressor are all automatic safety protection devices to prevent refrigeration compressor failures and even accidents. They play a good automatic control role for the safe operation of the machine. The setting of
safety devices can only prevent accidents related to the refrigerant cycle, but cannot prevent malfunctions or accidents caused by deficiencies in equipment, materials, processing technology, etc. Therefore, it is first required that the quality and mechanical properties of the manufacturing materials used in the refrigeration device of the supermarket refrigerated showcase must meet the general standards of mechanical manufacturing. The mechanical materials that contact ammonia and lubricants should be chemically stable to ammonia and lubricants. It can withstand the requirements of different pressure and temperature changes during work.
Implement correct adjustments; ensure the quality of supermarket refrigerated showcase and other mechanical equipment; have complete safety devices and implement safe operations. The three are properly coordinated to protect the safe operation of machines and equipment and prevent accidents. .
