多级离心泵的功率损失有三种：水力损失，容积损失，机械损失。下面将对这三种功率损失做简单介绍；

（1）水力损失：液体在泵体内流动时，如果流道光滑，阴力就小些，流道粗糙，阴力就大些，水流进入到转到的叶轮和水流从叶轮中出来时还会产生碰撞和旋涡引起损失。上两种损失叫做水力损失。

（2）容积损失：叶轮是转动的，而泵体是静止的，流体在叶轮和泵体之间的间隙中一小部分回流到叶轮的进口；另外，有一部分流体从平衡孔回流到叶轮进口，或从轴封处漏损。如果是多级泵，从平衡盘也要漏损一部分。这些损失，叫容积损失。

（3）机械损失：轴在转动时要和轴承、填料等发生磨擦，叶轮在泵体内转动，叶轮前后盖板要与流体产生磨擦，都要消耗一些功率，这些由于机械磨擦引起的损失，总称为机械损失。125D25*8离心清水泵;125D25*8;125D25*8离心清水泵;125D25*8;125D25*8离心清水泵;125D25*8;125D25*8离心清水泵;125D25*8;125D25*8离心清水泵;125D25*8;125D25*8离心清水泵;125D25*8;125D25*8离心清水泵;125D25*8;125D25*8离心清水泵;125D25*8;125D25*8离心清水泵;125D25*8;125D25*8离心清水泵;125D25*8;125D25*8离心清水泵;125D25*8;125D25*8,125D25*8,125D25*8,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,125D25*8,125D25*8,125D25*8,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,125D25*8,125D25*8,125D25*8,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,125D25*8,125D25*8,125D25*8,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,125D25*8,125D25*8,125D25*8,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,125D25*8,125D25*8,125D25*8,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,125D25*8,125D25*8,125D25*8,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,,125D25*8,125D25*8离心清水泵;125D25*8
