"En为没有空间设置蓄水池我们有三台155t的水泵打算从同一总管吸水现在担心前面的泵影响后面的泵吸水因此考虑把总管加大按1.5m/s的速度流量是三台泵总流量的和倍来计算总管管径但是不知道这样够粗了不。要没要规范或者经验要求总管的大小",

"L'entrée的进口管按取为比较大的的也偏小也还是要计算一下汽蚀余量另外如果担心分配不均对称布置就好了",

"Merci您回复那能不能具体说一下流速和流量的倍数为多少取比较合适呢另外由于厂房限制没法对称布置只能安装在管道同一侧另外汽蚀余量计算是指什么刚接触这一块儿还不太懂",

"Généraally选择低于为m/s吧为倍也取决于你单台进料管尺寸如果够大也为倍也够够但你这个为m/s为倍肯定不合适汽蚀余量是泵计算的基础知识百度或者找本相关书籍都有讲的",
