压缩机气阀是压缩机中一个很重要的组件,也是一个易损件,随着运行时间的增加,随时有可能失效,那么如何在压缩机运行过程中,及时发现气阀的故障呢?其实气阀失效后,压缩机在这三个方面有非常明显的变化,他们分别是:温度、压力、排气量

分析如下:

1、如果进气阀关闭不严,则当气缸内气体被压缩时,缸内气体会漏向吸气管道,这样吸气温度上升,压力升高,同时由于部分气体回流导致流量下降

2、如果排气阀关闭不严,则当气缸内停止排气后开始吸气时,排气管道内的部分高压气体会回流到气缸内,导致排气压力下降,同时这些回流气体未冷却,温度很高,从而使排气温度上升。流量自然明显下降

通过以上分析,我们检查气阀是否正常就很简单了,只需要三步:

1、看流量:当压缩机流量有下降时,有可能是气阀失效造成的

2、看压力:当气缸的进口压力升高,而排气压力下降,预示着气阀有可能出现故障

3、测温度:这是最关键的一步,花几十元买一把测温枪,测气阀阀盖,如果温度升高,则这个气阀应该有问题了
