多級(jí)離心泵的功率損失有三種：水力損失，容積損失，機(jī)械損失。下面將對(duì)這三種功率損失做簡(jiǎn)單介紹；

（1）水力損失：液體在泵體內(nèi)流動(dòng)時(shí)，如果流道光滑，陰力就小些，流道粗糙，陰力就大些，水流進(jìn)入到轉(zhuǎn)到的葉輪和水流從葉輪中出來時(shí)還會(huì)產(chǎn)生碰撞和旋渦引起損失。 上兩種損失叫做水力損失。

（2）容積損失：葉輪是轉(zhuǎn)動(dòng)的，而泵體是靜止的，流體在葉輪和泵體之間的間隙中一小部分回流到葉輪的進(jìn)口；另外，有一部分流體從平衡孔回流到葉輪進(jìn)口，或從軸封處漏損。如果是多級(jí)泵，從平衡盤也要漏損一部分。這些損失，叫容積損失。

（3）機(jī)械損失：軸在轉(zhuǎn)動(dòng)時(shí)要和軸承、填料等發(fā)生磨擦，葉輪在泵體內(nèi)轉(zhuǎn)動(dòng)，葉輪前后蓋板要與流體產(chǎn)生磨擦，都要消耗一些功率，這些由于機(jī)械磨擦引起的損失，總稱為機(jī)械損失。100D45*8離心清水泵;100D45*8清水離心泵;100D45*8礦用多級(jí)泵;100D45*8礦用離心泵;100D45*8離心清水泵;100D45*8清水離心泵;100D45*8礦用多級(jí)泵;100D45*8礦用離心泵;100D45*8離心清水泵;100D45*8清水離心泵;100D45*8礦用多級(jí)泵;100D45*8礦用離心泵;100D45*8離心清水泵;100D45*8清水離心泵;100D45*8礦用多級(jí)泵;100D45*8礦用離心泵;100D45*8離心清水泵;100D45*8清水離心泵;100D45*8礦用多級(jí)泵;100D45*8礦用離心泵;100D45*8離心清水泵;100D45*8清水離心泵;100D45*8礦用多級(jí)泵;100D45*8礦用離心泵;100D45*8離心清水泵;100D45*8清水離心泵;100D45*8礦用多級(jí)泵;100D45*8礦用離心泵;100D45*8離心清水泵;100D45*8清水離心泵;100D45*8礦用多級(jí)泵;100D45*8礦用離心泵;100D45*8離心清水泵;100D45*8清水離心泵;100D45*8礦用多級(jí)泵;100D45*8礦用離心泵;100D45*8離心清水泵;100D45*8清水離心泵;100D45*8礦用多級(jí)泵;100D45*8礦用離心泵;100D45*8離心清水泵;100D45*8清水離心泵;100D45*8礦用多級(jí)泵;100D45*8礦用離心泵; ;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8;100D45*8
