class="box"><p>輔助密封元件的結(jié)構(gòu)形式摩擦副的動、靜環(huán)的結(jié)構(gòu)形式往往取決于所采用的輔助密封元件的形式。輔助密封元件有兩類：徑向接觸式輔助密封與波紋管輔助密封。 <p> a.徑向接觸式輔助密封徑向接觸式輔助密封包括動環(huán)密封圈和靜環(huán)密封圈，它們分別構(gòu)成動環(huán)與軸、靜環(huán)與端蓋之間的密封。同時，由于密封圈材料具有彈性，遼寧襯氟泵批發(fā)，能對密封環(huán)起彈性支承作用，并對密封端面的歪斜和軸的振動有一定的補償和吸振效果，可提高密封端面的貼合度。當端面磨損后，遼寧襯氟泵批發(fā)，遼寧襯氟泵批發(fā)，在彈性力作用下，密封圈隨補償環(huán)沿軸向作微小的補償移動。酸堿泵哪家好，上海原孚泵業(yè)值得信賴，歡迎您的光臨！遼寧襯氟泵批發(fā)</p><div

離心泵維護及檢修一、離心泵檢修與質(zhì)量標準1、拆卸前準備掌握泵的運轉(zhuǎn)情況，并備齊必要的圖紙和資料。備齊檢修工具、量具、起重機具、配件及材料。切斷電源及設(shè)備與系統(tǒng)的聯(lián)系，放凈泵內(nèi)介質(zhì)，達到設(shè)備安全與檢修條件。2、拆卸與檢查拆卸附屬管線，并檢查清掃。拆卸聯(lián)軸器安全罩，檢查聯(lián)軸器對中，設(shè)定聯(lián)軸器的定位標記。測量轉(zhuǎn)子的軸向竄動量，拆卸檢查軸承。拆卸密封并進行檢查。測量轉(zhuǎn)子各部圓跳動和間隙。拆卸轉(zhuǎn)子，測量主軸的徑向圓跳動。檢查各零部件，必要時進行探傷檢查。檢查通流部分是否有汽蝕沖刷、磨損、腐蝕結(jié)垢等情況。 </p><p> 離心泵汽蝕的識別汽蝕是造成離心泵的性能和效率下降的主要原因之一，及時識別出汽蝕的發(fā)生，便于采取相應(yīng)的防范措施，實際生產(chǎn)中可根據(jù)如下幾種辦法判別是否發(fā)生了汽蝕。1、根據(jù)噪音識別汽蝕發(fā)生時由于液體撞擊會產(chǎn)生各種噪聲，并且當汽蝕嚴重時，可聽到泵內(nèi)發(fā)出類似于爆竹的噼噼啪啪的聲音。我們可以據(jù)此作為汽蝕的判斷。2、根據(jù)振動識別離心泵的汽蝕伴隨著泵體的振動，因此可以在泵體上加振動傳感器，當泵運行時發(fā)現(xiàn)振動與正常有異，應(yīng)該首先考慮是否發(fā)生了汽蝕。在實際生產(chǎn)中，我們可以根據(jù)經(jīng)驗感覺出泵體振動的不同，從而初步判定是否產(chǎn)生了汽蝕。氟塑料離心泵哪家專業(yè)，上海原孚泵業(yè)值得信賴，歡迎有需求的朋友們聯(lián)系我司！</p><div

二、水泵軸向力平衡方法平衡水泵轉(zhuǎn)子軸向力的方法多種多樣，例如在泵外部設(shè)置推力軸承、于水泵腔體上開設(shè)平衡孔或平衡管以降低泵壓、葉輪設(shè)計時采用背葉片、雙葉輪、葉輪對稱分布等形式，以及使用平衡盤、平衡鼓結(jié)構(gòu)等。其中，多利用平衡盤和平衡鼓結(jié)構(gòu)對轉(zhuǎn)子軸向力進行平衡。平衡盤被廣泛應(yīng)用在多級泵的軸向力平衡上，位于泵末級葉輪之后。平衡裝置存在徑向和軸向兩個間隙，由末級流出的帶壓液體，經(jīng)徑向間隙流入平衡盤前的空腔中，使之形成高壓力狀態(tài)。于平衡盤后側(cè)的空腔上開設(shè)平衡管，并與水泵入口相連通，使該處空腔內(nèi)壓力與泵入口處壓力基本一致。由于平衡盤前后兩空腔內(nèi)壓力不等，構(gòu)成壓力差，產(chǎn)生與軸向力反向的平衡力，達到平衡效果。采用平衡盤結(jié)構(gòu)平衡水泵轉(zhuǎn)子軸向力時，由于軸向力不斷變化，平衡力也隨之改變，因而，其工作過程是動平衡過程。平衡盤依靠轉(zhuǎn)子竄動自動調(diào)節(jié)其可變間隙大小，從而調(diào)節(jié)平衡力大小，能夠充分平衡轉(zhuǎn)子軸向力，無需依靠外部推力軸承輔助，因而平衡結(jié)構(gòu)可省略外部推力軸承。氟塑料離心泵選哪家，上海原孚泵業(yè)為您服務(wù)！歡迎您的光臨！湖南氟塑料化工泵公司</p><p
