機(jī)械密封處滲©水的第一種可能性是機(jī)封的動、靜環(huán)平面磨損。而造成機(jī)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(jī)械密封的動靜環(huán)平面，麗水電動泵密封的用途和特點，如有嚴(yán)重?zé)宫F(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(qiáng)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(jī)封動、靜環(huán)平面，其表面有一層很薄的水垢，能夠擦去，麗水電動泵密封的用途和特點，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(jī)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(jī)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(jìn)水壓或介質(zhì)，更換機(jī)封，麗水電動泵密封的用途和特點。 </p> <p> 原因四、缺水運行造成干磨損壞。此現(xiàn)象多見于底閥式安裝形式進(jìn)口處負(fù)壓，進(jìn)水管有空氣，泵腔內(nèi)有空氣，泵開機(jī)后，機(jī)封的磨擦高速運轉(zhuǎn)時產(chǎn)生高溫，無法得到冷卻，檢查機(jī)封，彈簧張力正常，摩擦面燒焦發(fā)黑，橡膠變硬開裂。處理辦法：排盡管道及泵腔內(nèi)空氣，更換機(jī)械密封。 </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="麗水電動泵密封的用途和特點" src="https://tyunfile.71360.com/UploadFile/lscmjx/637247266600576172/7557626.jpg"></div><p> 化工泵油封是一種自緊式唇狀密封，其結(jié)構(gòu)簡單，尺寸小，成本低廉，維護(hù)方便，阻轉(zhuǎn)矩較小，既能防止介質(zhì)泄漏，也能防止外部塵土和其它有害物質(zhì)侵入，而且對磨損有一定的補(bǔ)償能力，但不耐高壓，所以一般用在低壓場合的化工泵上。 </p> <p> 化工泵依靠離心原理來抽取液體物料，特殊材料制成的化工泵適用于瓶、桶、缸、池或其他容器中抽取腐蝕性液體。由于化工泵所抽取的介質(zhì)有腐蝕、揮發(fā)、等危險性的存在，對泵體的密封性能要求，要比其他種類的泵高很多。 </p> <p> 化工泵油封應(yīng)安裝在制造精度為h8～h9，表面粗糙度為1.6～0.8μm且經(jīng)過表面硬化處理的軸上。密封介質(zhì)不應(yīng)含有固體微粒和雜質(zhì)，否則會造成油封和軸的迅速磨損而使密封失效。 </p> <p> 在選擇此種密封方法是，要充分考慮化工泵所輸送到物料的性能和要求，以避免不必要的泄漏，防止意外的發(fā)生。 </p> <p> 造成油封漏油的主要因素： </p> <p> 油封密封不嚴(yán)是造成漏油的主要因素。當(dāng)軸出現(xiàn)磨損形成溝槽，即使更換新油封仍不能密封時，是由于油封唇口與軸的接觸壓力下降，造成安裝后油封唇直徑與軸徑的過盈量太小。 </p> <p> 現(xiàn)以S195型柴油機(jī)曲軸油封為例，分析其密封不嚴(yán)的主要原因是：油封制造質(zhì)量差軸或軸承質(zhì)量差使用維護(hù)不當(dāng)安裝不當(dāng)保管不當(dāng)，受環(huán)境污染造成不良影響 </p> <p> <br /> </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="麗水電動泵密封的用途和特點" src="https://tyunfile.71360.com/UploadFile/lscmjx/637247298412392578/7048929.jpg"></div><p> 雙重密封和液體阻隔裝置 </p> <p> 采用雙重密封面的密封來代替單一的密封件具有更高程度的防漏特性。這類雙重密封大都應(yīng)用于揮發(fā)性強(qiáng)、危險和潤滑性很差的液體。 </p> <p> <span style="font-size:12px;"> 雙重密封一般有三種設(shè)計型式，每種型式都要求在雙重密封面之間使用一種液體阻隔系統(tǒng)，以防止液體或氣體外泄。比較常用的低成本雙重密封是一種以背靠背方式安裝的密封，其旋轉(zhuǎn)密封面以相反的方向排列。它往往需要一種阻隔液體，其壓力應(yīng)高于填料盒壓力，大約為20psi，這樣就可保證內(nèi)部的密封始終能得到阻隔液體的潤滑，而且也可保證密封面達(dá)到一定的密封壓力。</span>
