以上檢修工作完成后，湖北閥門密封，需要重新安裝機封，在安裝前先必須做好準備工作： </p> <p> 1、如果更換新機封，須檢查機械密封的型號、規(guī)格是否正確，質(zhì)量是否符合標準； </p> <p> 2、靜環(huán)尾部防轉(zhuǎn)槽端與防轉(zhuǎn)銷頂部應(yīng)保持1mm-2mm的軸向間隙，以免緩沖失效； </p> <p> 3、動、靜環(huán)端面用酒精清洗干凈，其余金屬件用汽油清洗并用潔凈的壓縮空氣吹干，仔細檢查務(wù)心保證動，湖北閥門密封、靜環(huán)密封面沒有任何損傷。裝配前，兩件“0”形橡膠密封圈應(yīng)涂上一層潤滑油膏，動、靜環(huán)端面不許涂油。 </p> <p> 機械密封的安裝 </p> <p> 機封安裝順序及注意事項如下： </p> <p> 1、在轉(zhuǎn)子與泵體的相對位置固定之后，確定機械密封的安裝位置，根據(jù)密封的安裝尺寸及靜環(huán)在壓蓋中的位置，測算出密封在軸或軸套上的定位尺寸； </p> <p> 2、安裝機封動環(huán)，動環(huán)安裝后須保證能其在軸上靈活移動； </p> <p> 3、將組裝好的靜環(huán)部分和動環(huán)部分組裝好； </p> <p> 4，湖北閥門密封、把密封端蓋裝在密封體內(nèi)，并將螺絲擰緊。 </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="湖北閥門密封" src="https://tyunfile.71360.com/UploadFile/lscmjx/637245508261533203/8577088.jpg"></div><p> 水泵處理方法 </p> <p> 1 機械密封處滲水的第一種可能性是機封的動、靜環(huán)平面磨損。而造成機封的動、靜環(huán)平面磨損的原因有六個方面： </p> <p> 原因一、安裝過緊。觀察機械密封的動靜環(huán)平面，如有嚴重燒焦現(xiàn)象，平面發(fā)黑和很深的痕跡，密封橡膠變硬，失去彈性，這種現(xiàn)象是由于安裝過緊造成的。 </p> <p> 處理辦法：調(diào)整安裝高度，葉輪發(fā)裝后，用螺絲刀拔動彈簧，彈簧有較強的張力，松開后即復(fù)λ，有24MM的移動距離即可。 </p> <p> 原因二、安裝過松。觀察機封動、靜環(huán)平面，其表面有一層很薄的水垢，能夠擦去，表面基本無磨損，這是彈簧失去彈性及裝配不良造成，或電機軸向竄動造成。 </p> <p> 原因三、水質(zhì)差含顆粒。由于水質(zhì)差，含有小顆粒及介質(zhì)中鹽酸鹽含量高，形成磨料磨損機封的平面或拉傷表面產(chǎn)生溝槽、環(huán)溝等現(xiàn)象。 </p> <p> 處理辦法：改進水壓或介質(zhì)，更換機封。 </p> <p> <br /> </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="湖北閥門密封"

HG20592~20635-1997規(guī)定采用非金屬墊密封時，法蘭密封面可車制密紋水線或要求法蘭密封面表面粗糙度。對于突面法蘭如車制密紋水線，則標記為“RF（A）”。小編也曾在現(xiàn)場開箱驗收時，遇到安裝公司驗收人員發(fā)現(xiàn)法蘭密封面不光滑提出疑問。那么，法蘭密封面必須車制密紋水線嗎？在工廠制造法蘭時一般都在密封面上均勻的車2-3道，水線一般是深1mm，90度,寬度在5mm，密封水紋線的加工，有利于法蘭的密封，而且制造上也容易實現(xiàn)。但這種密紋水線一般用在軟墊片上。由于墊片是軟的，法蘭面通過擠壓，使墊片進入到這些線中，起到密封的作用。密紋水線的加入，把一個密封面分成了好幾個密封面，水線好比迷宮，減少了介質(zhì)泄露的可能。新的標準取消了密紋水線的要求，在HG/T20592~20635-2009中規(guī)定，突面、凹面/凸面及全平面密封面是采用加工車刀加工時自然形成的一種鋸齒形同心圓或螺旋齒槽。加工車刀的圓角半徑應(yīng)不小于，形成的鋸齒形同心圓或螺旋齒槽深度約為，節(jié)距約為。這樣也起到了增加密封效果的作用，只不過紋線是加工時自然出現(xiàn)的細密紋線，而水線則是單獨加工出來的2道或3道較深的槽，而且密紋水線不能是螺旋線。
