如题,机泵的出入口管线相连(就是中间加个跨线)是否可以当做循环线?
Reply #22017-10-27
可以的,就是接到入口管道上的位置需要考虑。我们的导热油管线就是在进车间的进出管道上相连,并且按照阀门。

我见过的循环线都是做到容器底部的啊

导热油可以,液化烃这样接的话是不是容易气化?
Reply #52017-10-28
就是要考虑接入位置,距离泵入口远一点。

按照你给的这个说法肯定是不可以的,泵在做功有部分转化为内能使液体温度上升,离心泵使液体强烈搅动泵就气蚀了

重油泵都会这样做的(预热的作用),液化气泵(高速泵)有得也有,为了调节量的。我们称反罐线

楼主说的是机泵,这个不好接到容器底部的

液态烃也没有问题,只要泵入口的压力不是太低就不会汽化的

一般都是从泵出口阀上面接线至泵出口止回阀前面 跨过止回阀和泵出口阀

联通线有两种,换有一种是为了修泵,整体切除时候,跨线开口都在出入口阀上面
