"深井泵",

"Chers amis de de la mer : La profondeur de de la 35m,a, la pressionure à la sortie (sur la surface) de de 5 001 5MPa,a un rendement de 85m,a,可以关小出口阀进行限流,降低电耗吗?",

"为什么要关小出口阀,变小流量,扬程升高,a 关小出口阀后性能参数满足要求吗 如果关小出口阀只是为了节能 那么与关小出口阀相比 切割叶轮直径更直接有效。",

"水泵扬程与实际需求偏差太大 工作时会出现超载现象。a 可以通过关小阀门限流(权宜之计)最根本的是换泵。",

"这个吧 �配套的都有个自动控制柜 使用时出口阀门控制到电流的额定范围时的最大流量 �并将这个出口阀门控制开度设定不能动 否者者超流量是要引起电流升高跳闸的。至于系统停水不用 控制箱会自动控制的。",

"泵是有两个最基本的参数组成 �量和扬程 从你的描述来看泵的扬程是够了 你如果只是为了减少流量完全可以采取关小出口阀门的办法。",

的确,我们一台深井泵该变频泵后,低转速时振动就大

需要加量的时候又不行了?
Reply #102018-11-23
是的。那就要你自己权衡了,如果只是偶尔加量的话我个人认为还是切了好些。

可以考虑撤下一级叶轮,或者干脆改造泵,有问题可以私下联系
Reply #122018-11-26
暂时调节一下,应该可以吧!

调节出口阀门不是长期的办法,虽然能降低一些能量,但是能量都损失在出口阀门上了。三种办法节能,换泵,改变频,切叶轮
