氨气压缩机的机械密封(轴封)是压缩机的重要部件之一,它关系着整个机组的正常运行。由于其属于消耗类零件,容易磨损,导致泄漏失效。所以压缩机的检修工作很大一部分都是围绕着机械密封展开的。通过对其失效诊断、维修、保养,从而总结出一系列经验,延长其寿命,提高企业的经济效益。 Ammonia compressor mechanical seal (shaft seal) is one of the important components of the compressor, it is related to the normal operation of the entire unit. As it belongs to the consumption of parts, easy to wear, resulting in leakage failure. Therefore, a large part of the compressor repair work is carried out around the mechanical seal. Through its failure diagnosis, repair, maintenance, which concluded a series of experience to extend its life expectancy and improve the economic efficiency of enterprises.
