不同泵不同工况有不同的备用方式,例如是否高温,考虑暖泵线。是否高压,考虑出口和返回。是否重要,考虑连锁自启等等。

这个要看整个装置的自动化程度,自动化程度高的一般都是常闭的,

不同的工况不同的操作。

这样说吧,我们装置大多数离心泵备泵都是进口阀全开,出口阀全关。需要切泵的时候现场开出口阀,这个应该是常规离心泵的操作吧,特殊情况另当别论。

按照离心泵操作规范,出口阀应关闭,避免出口单向阀失效导致物料反窜。如果长期不开泵,入口阀门关闭

备泵进出口全开,打自动

我们都是进口阀开,出口阀关闭,这样启泵能快点

我们这里大部分也是!双氧水装置。

如果是介质高温,备用泵除了关出开进外,还要打开暖泵阀门。
