   離心泵是一種葉片泵，依靠旋轉(zhuǎn)的葉輪在旋轉(zhuǎn)過程中，由于葉片和液體的相互作用，葉片將機械能傳給液體，使液體的壓力能增加，達到輸送液體的目的。離心泵工作有以下特點：

①離心泵泵在一定轉(zhuǎn)速下所產(chǎn)生的揚程有一限定值。工作點流量和軸功率取決于與泵連接的裝置系統(tǒng)的情況(位差、壓力差和管路損失)。揚程隨流量而改變。 

②工作穩(wěn)定，輸送連續(xù),流量和壓力無脈動。 

③一般無自吸能力,需要將泵先灌滿液體或?qū)⒐苈烦槌烧婵蘸蟛拍荛_始工作。 

④離心泵在排出管路閥門關閉狀態(tài)下啟動，旋渦泵和軸流泵在閥門全開狀態(tài)下啟動，以減少啟動功率。 

 在泵啟動前，泵殼內(nèi)灌滿被輸送的液體；啟動后，葉輪由軸帶動高速轉(zhuǎn)動，葉片間的液體也必須隨著轉(zhuǎn)動。在離心力的作用下，液體從葉輪中心被拋向外緣并獲得能量，以高速離開葉輪外緣進入蝸形泵殼。

    在蝸殼中，液體由于流道的逐漸擴大而減速，又將部分動能轉(zhuǎn)變?yōu)殪o壓能，最后以較高的壓力流入排出管道，送至需要場所。液體由葉輪中心流向外緣時，在葉輪中心形成了一定的真空，由于貯槽液面上方的壓力大于泵入口處的壓力，液體便被連續(xù)壓入葉輪中。可見，只要葉輪不斷地轉(zhuǎn)動，液體便會不斷地被吸入和排出。
