离心泵的设计压力为1Mpa时,是不是可以说泵的扬程是100m?

设计压力和扬程有啥关系?先搞清楚什么是扬程
Reply #32020-03-05
设计院的提示您:不是的,离心泵很少有用设计压力说扬程的,要说扬程都是用扬程。设计压力指的的壳体材料的设计压力。是泵能承受的内压力。

不是,设计压力是指泵承受压力的设计上限值,一般是进口压力+扬程之和,不说进口压力,单说与泵扬程之间的关系,不够准确

设计压力指泵能承受的工作压力,和材料和壁厚有关,设计压力肯定大于扬程的

不是,是他的设计上能承受的最大的管路出口压力,实际上如果设计压力是1.0MPa,我们出厂之前打压试验是1.5MPa,做测试。其他人做不做我不知道,我公司是做的。

这是两个概念,上面有的解释很好
