["活塞压缩机二级排气压力高怎么回事啊？

Reply #32017-03-16

各位海友，我们的活塞压缩机是三级四列的，这两天二级排气压力高，按以往经验，查了三级进排气阀都正常，换了新的气阀后，二级排气压力还是高，而且两台机出现同一情况。专家们们麻烦帮忙分析下，谢谢了！

查查各级冷却温度是否有变化？

出口冷却器效率低，冷却效果下降三级气阀、活塞环、支撑环故障如果压缩机运行了很长时间可以对三级管道进行一下清洗可能发生了堵塞造成官渡阻力过大压力的变化往往伴随着温度的变化可以再多提供一点信息便于判断分析

建议：检查三级进气温度根据以往是否有变化（上升）；检查冷却器的换热效果效果①管程是否有堵塞现象；②壳程换热效果下降。循环水上水温度是否太低。近期处于冷热交替阶段很容易出现冷却器换热效果变差的现象。

还可以检查下二段排气阀是不是有漏气的情况如果两台设备的二段都高是不是其他段也有相应升高的情况可能是压缩机气量增加了
