制冷机组的漏洞原因以及维修处理方法

1、制冷机系统中冲入制冷剂过量

引起原因:制冷剂过量导致排气压力显著上升,超出正常值。

处理方法:停机,在高压排气孔将多余制冷剂排出。

2、冷水机组系统内有残余空气

引起原因:系统内有空气循环,会出现排气压力过高,排气温度升高排气管烫手,制冷效果变差,压缩机运转不久,排气压力超过正常值,迫使压力继电器动作。

处理方法:停机,在排气阀孔处放空气。

3、制冷机吸气压力过低引起停机现象

引起原因:当系统内吸气压力低于压力继电器的调定值时,其触电动作而切断电源。

处理方法:制冷剂泄漏,系统有堵塞。

4、冷库机组电机超负荷

引起原因:使用时,库内放入过量食品;电源不正常。

处理方法:减少热负荷,注意电热电压的变化。
