一个项目冷却塔配的卧式离心泵，流量300方每小时，扬程50米，必需汽蚀余量4米。没地方装了要把水泵装到路对面泵房，进口水平管30多米。水泵进口低于冷却水池液面，进口管径比泵进口大一个规格，DN250.我算了下沿程阻力不大，不到1m，但是30多米远会有其他问题吗

泵汽蚀余量能满足的话没有问题的。但是离心泵的出口是强项，吸入是弱项，能改最好，毕竟入口30多米长的管线长期存水，不说易沉淀易腐蚀，单单对于检修管线阀门和泵，即便有阀门，但是还是要放那么多水是不方便的

管径大一规格是多少mm？学*学*

只要阻力小，满足汽蚀余量就行。

个人觉得循环水泵流量比较大，如果入口管线太长，影响吸入流量，也会加大吸入阻力，你可以适当把进口管线加大来消除。

正常情况下不会。可以适当提高塔的高度，增加泵进口液位高度。另，把管子放大两档。

是否会发生汽蚀，得需要计算配置，再经过现场检验。
