上海某船厂建造的一艘登陆舰,其冷藏系统配有三台R22的GJS3FW5B半封闭制冷机组,其中一台备用。机组和系统均未设油分离器。从冷库来的回汽管是从地面通行后爬高进压缩机吸入口的。在码头系泊试验时,发现机组首次起动时油压差建立不起来,但起动数次后,机组能运行,且在相当长的时间内系统的运行参数正常。但好景不长,突然在运行中停车。经查供电正常,机组自控保护
A landing ship built by a shipyard in Shanghai, the refrigeration system is equipped with three R22 GJS3FW5B semi-enclosed refrigeration units, one of the spare. Unit and system are not set oil separator. The return pipe from the freezer is climbed into the inlet of the compressor from the ground. During the dock mooring test, it was found that the hydraulic pressure difference was not established when the unit was first started, but after several starts, the unit was able to operate and the system’s operating parameters were normal for quite a long time. But not good for a long time, suddenly stopped in operation. The investigation of normal power supply, automatic control unit
