機泵在運行中液體與泵體產(chǎn)生的流動摩擦，轉(zhuǎn)動部分與固定部分如軸承的滾珠與內(nèi)外圈、軸套與填料等部分會產(chǎn)生摩擦，因摩擦?xí)a(chǎn)生熱量，同時由于介質(zhì)溫度高傳導(dǎo)給機泵，使泵體發(fā)熱，冷卻的目的是降低泵體、泵座、軸承箱、軸封處溫度，防止這些部位因溫升而變形、老化和損壞，北京臥式耐腐蝕離心泵型號。 </p> <p>

style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="北京臥式耐腐蝕離心泵型號" src="https://tyunfile.71360.com/UploadFile/jjsrxby/637255207796054688/2906638.jpeg"></div><p> 當(dāng)離心泵啟動后，泵軸帶動葉輪一起作高速旋轉(zhuǎn)運動，迫使預(yù)先充灌在葉片間液體旋轉(zhuǎn)，在慣性離心力的作用下，液體自葉輪中心向外周作徑向運動。 </p> <p> 液體在流經(jīng)葉輪的運動過程獲得了能量，靜壓能增高，流速增大。當(dāng)液體離開葉輪進入泵殼后，由于殼內(nèi)流道逐漸擴大而減速，部分動能轉(zhuǎn)化為靜壓能，***沿切向流入排出管路。 </p> <p> 所以蝸形泵殼不僅是匯集由葉輪流出液體的部件，而且又是一個轉(zhuǎn)能裝置。當(dāng)液體自葉輪中心甩向外周的同時，葉輪中心形成低壓區(qū)，在貯槽液面與葉輪中心總勢能差的作用下，致使液體被吸進葉輪中心。依靠葉輪的不斷運轉(zhuǎn)，液體便連續(xù)地被吸入和排出。液體在離心泵中獲得的機械能量**終表現(xiàn)為靜壓能的提高。 </p><div
