知識交流區(qū)--------------------------MD礦用耐磨多級離心泵安裝應該注意什么？
安裝注意事項  1、安裝時管路重量不應承受在泵上，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、安裝水泵前應仔細檢查泵流道內(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：  3、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，還應在出口閘閥前安裝一只止回閥以應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；  3、泵用于有吸程場合，應裝有底閥，并且進口管路不應有過多彎道，同時不得有漏水、漏氣現(xiàn)象，以免影響水泵的吸入性能；  3、為不使雜質(zhì)進入泵內(nèi)而堵塞流道影響性能，應在泵進口前面安裝過濾器；  3、安裝管路前轉(zhuǎn)動水泵的轉(zhuǎn)子部件，應無磨擦或卡死現(xiàn)象，否則應將泵拆開檢查原因。

{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，采購時應注意辨別材料。
五、選型：水泵的水模型需要經(jīng)過設計選型，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)量跟蹤服務卡等。
