氨制冷设备充分广泛使用于化工、食品、制药及冷库等行业。常见的液氨制冷系统主要由压力容器、压力管道组成,有冷凝器、贮氨器、油分离器、集油器中间冷却器,氨液分离器,低压循环贮液罐和排液桶等组成,主要介质均为氨(R717)随着经济迅速发展,冷库遍布很广,由于管理不到位,氨制冷设备压力容器腐蚀或裂纹造成压力容器裂纹、失效,以致造成氨的泄漏事故,所以氨制冷系统,管道、压力容器必须及时进行定期检验,按"压力容器定期检验规则要求侧重检验,腐蚀、裂纹、渗漏管理等方面存在的问题。
Ammonia refrigeration equipment is widely used in chemical, food, pharmaceutical and cold storage industries. Common liquid ammonia refrigeration system is mainly composed of pressure vessel, pressure pipe, condenser, ammonia storage device, oil separator, oil cooler intercooler, ammonia separator, low pressure circulating liquid storage tank and drainage barrel and other components , The main medium is ammonia (R717) With the rapid economic development, cold storage throughout a very wide, due to management is not in place, ammonia refrigeration equipment pressure vessel corrosion or cracks caused by pressure vessel cracks, failure, resulting in ammonia leakage accident, so ammonia refrigeration The system, pipelines and pressure vessels must be regularly inspected in time. According to the regulations of the pressure vessel regular inspection rules, the problems of inspection, corrosion, cracks and leakage management should be emphasized.
