知識交流區(qū)--------------------------MD礦用耐磨多級離心泵安裝應(yīng)該注意什么？
安裝注意事項 1、安裝時管路重量不應(yīng)承受在泵上，否則易損壞水泵； 2、安裝時必須擰緊地腳螺栓，且每間隔一定時段應(yīng)對泵進行檢查防止其松動，以免水泵起動時發(fā)生劇烈振動而影響泵的性能； 3、安裝水泵前應(yīng)仔細(xì)檢查泵流道內(nèi)有無影響水泵運行的硬質(zhì)物(如石塊、鐵砂等)以免水泵運行時損壞過流部件： 4、為了維護方便和使用安全，在泵的進出口管路上安裝一只調(diào)節(jié)閥及在泵進出口附近安裝一只壓力表，對于高揚程泵，為防止水錘，還應(yīng)在出口閘閥前安裝一只止回閥以應(yīng)付突然斷電等失去動力而生產(chǎn)的事故，從而確保水泵在最佳工況下運行，延長水泵的使用壽命； 5、泵用于有吸程場合，應(yīng)裝有底閥，并且進口管路不應(yīng)有過多彎道，同時不得有漏水、漏氣現(xiàn)象，以免影響水泵的吸入性能； 6、為不使雜質(zhì)進入泵內(nèi)而堵塞流道影響性能，應(yīng)在泵進口前面安裝過濾器； 7、安裝管路前轉(zhuǎn)動水泵的轉(zhuǎn)子部件，應(yīng)無磨擦或卡死現(xiàn)象，否則應(yīng)將泵拆開檢查原因。
相關(guān)參數(shù)：

[友情提醒]：
一、離心泵按被輸送液體的性質(zhì)分類。
二、根據(jù)流量及計算管路壓頭(揚程)，確定泵的型號。
三、介質(zhì)：若被輸送液
體的粘度和密度與水相差較大時，應(yīng)核算泵的特性參數(shù)：流量、壓頭和軸功率。
四、材料：注意電機用材不足并選用低劣材料，采購時應(yīng)注意辨別材料。
五、選型：水泵的水模型需要經(jīng)過設(shè)計選型，要注意查看產(chǎn)品的加工工藝和裝配質(zhì)量。
六、終查：看所選產(chǎn)品是否具備相應(yīng)的生產(chǎn)許可證，檢驗試驗書面報告和產(chǎn)品銘牌、說明書、合格證、信譽卡、質(zhì)量跟蹤服務(wù)卡等。
