定期切换也不做?为什么呢?

俺们的压缩机是螺杆的,都是厂家保养,生产用的是往复式的,没有联锁,检查--盘车--开启--关闭另一个油泵--关闭阀门就可以了

我们好像是直接通过开运行泵的回油阀和关备用泵的回油阀来调节的,两个泵的出口阀没有动作。

一般油泵都带辅油泵低压联锁,简单点的做法就是将运行泵停掉,系统自保会启动备用泵,然后将原运行泵打远传就完成了切换,这种做法不建议运行的离心式压缩机使用,风险较大,操作不好会导致联锁停机。第二种建议按照主备机切换并主风思维来操作,具体做法就是先将备用泵打就地,备用泵出口阀全关,返罐线全开,启备用机泵,稍开备用泵出口阀,看润滑油总管压力稍升时,稍开原运行泵返罐阀,待压力稳住后,继续关备用泵返罐阀,开备用泵出口阀,压力稳住后,开运行泵返罐阀,关运行泵出口阀,就这样多次操作,最后将运行泵切除,运行泵出口阀全关,返罐阀开,不一定全开,在操作过程中,幅度一定不能太大,要平稳操作
