闭式循环系统,泵出口压力等于进口压力加扬程。扬程是用来给水提供动力的。水在管道里面流动,由于水有一定的粘性,与管道壁接触就有阻力,还有就是阀门管道等阻力。流速低则管阻小,流速大则管阻大。假如你的管阻正常流速下是5米,你用30米泵去打,这时你的系统压力会很大的,当达到一个值的时候就会趋于稳定,因为流速越大阻力越大,一直到阻力等于泵扬程后就平衡了。你那个正常。

Z. 管道的沿程阻力太小了吧?

Z. 按LZ的描述,压力高的主要原因应该是自来水系统压力变化造成的Z平时自来水压力只有0Z3(自来水正常消耗)Z有时自来水消耗陡降导致压力明显上升。建议观察一下自来水用户用水状况Z同时在泵出口安装安全阀。

按LZ的描述,压力高的主要原因应该是自来水系统压力变化造成的,平时自来水压力只有0.3(自来水正常消耗),有时自来水消耗陡降导致压力明显上升。建议观察一下自来水用户用水状况,同时在泵出口安装安全阀。
