</p> <p> (1) 715kW以下小自吸式離心泵機(jī)封失效常常產(chǎn)生磨軸,磨軸位置主要有以下幾個(gè):動(dòng)環(huán)輔助密封圈處、靜環(huán)位置、少數(shù)彈簧有磨軸現(xiàn)象。 </p> <p> (2)磨軸的主要原因:①BIA型雙端面機(jī)械密封,反壓狀態(tài)是不良的工作狀態(tài),介質(zhì)中的顆粒、自吸式磁力泵雜質(zhì)很容易進(jìn)入密封面,使密封失效。②磨軸的主要件為橡膠波紋管，淮安密封源頭好貨,且是由于上端密封面處于不良潤(rùn)滑狀態(tài),動(dòng)靜環(huán)之間的摩擦力矩大于橡膠波紋管與軸之間的傳遞轉(zhuǎn)矩,發(fā)生相對(duì)轉(zhuǎn)動(dòng)。③動(dòng)、靜環(huán)輔助密封由于受到污水中的弱酸，淮安密封源頭好貨、弱堿的腐蝕,橡膠件已無(wú)彈性。有的已腐爛,失去了應(yīng)有的功能,產(chǎn)生了磨軸的現(xiàn)象。 </p> <p> (3)為解決以上問(wèn)題,現(xiàn)采取如下措施:①保證下端蓋，淮安密封源頭好貨、油室的清潔度,對(duì)不清潔的潤(rùn)滑油禁止裝配。不銹鋼齒輪油泵②機(jī)封油室腔內(nèi)油面線(xiàn)應(yīng)高于動(dòng)靜環(huán)密封面。③根據(jù)不同的使用介質(zhì)選用不同結(jié)構(gòu)的機(jī)封。對(duì)高揚(yáng)程泵應(yīng)重新設(shè)計(jì)機(jī)封構(gòu),對(duì)腐蝕性介質(zhì)橡膠應(yīng)選用耐弱酸、弱堿的氟橡膠。機(jī)封靜環(huán)應(yīng)加防轉(zhuǎn)銷(xiāo)。

常見(jiàn)的用于液壓油缸的密封圈又以下這些類(lèi)型：防塵圈、活塞桿密封圈、緩沖密封圈、導(dǎo)向支撐環(huán)、端蓋密封圈和活塞密封圈。 </p> <p> 防塵圈 </p> <p> 防塵圈安裝在液壓缸端蓋的外側(cè)，用于防止外部污染物進(jìn)入油缸，根據(jù)安裝方式又可分為卡入式和壓入式。 </p> <p> 卡入式防塵圈**為常見(jiàn)，顧名思義，防塵圈卡在端蓋內(nèi)壁的凹槽里，用于不那么苛刻的環(huán)境條件下。卡入式防塵圈的材料通常為聚氨酯，結(jié)構(gòu)形式有多種變體，如H和K型截面為雙唇結(jié)構(gòu)，但萬(wàn)變不離其宗。 </p> <p> 壓入式防塵圈用于嚴(yán)苛、重負(fù)荷的條件下，并不卡在凹槽中，而是聚氨酯材料外包裹一層金屬以增加強(qiáng)度，壓入液壓缸端蓋內(nèi)。壓入式防塵圈也有多種形式，也分單唇和雙唇。 </p> <p> 活塞桿密封圈 </p> <p> 活塞桿密封圈也被稱(chēng)作U型杯，是主要的活塞桿密封件，安裝在液壓缸端蓋內(nèi)側(cè)，作用是防止液壓油外漏?；钊麠U密封圈由聚氨酯或丁腈橡膠制成，在某些場(chǎng)合，需要與支撐環(huán)（也叫擋圈）一起使用，支撐環(huán)用于防止密封圈在壓力作用下發(fā)生擠壓變形?；钊麠U密封圈也有多種變體。淮安密封源頭好貨由于介質(zhì)和工作條件的不同，機(jī)械密封對(duì)耐高溫性能、耐高壓性能、耐腐蝕性能往往有著比較大的差距。</p><div

泵機(jī)械密封水的故障是水泵故障中容易出現(xiàn)的故障之一，所以水泵機(jī)械密封也屬于水泵部件中比較關(guān)鍵的易損件之一，水泵選型時(shí)機(jī)械密封材質(zhì)一定要能適合用戶(hù)輸送的液體介質(zhì)，通常水泵出廠都是氟橡膠機(jī)械密封，有的廠家是丁晴橡膠機(jī)械密封，如果腐蝕性比較嚴(yán)重得選用四氟材質(zhì)的機(jī)械密封。 </p> <p> 1 機(jī)械密封處滲水的第一種可能性是機(jī)封的動(dòng)、靜環(huán)平面磨損。而造成機(jī)封的動(dòng)、靜環(huán)平面磨損的原因有六個(gè)方面： </p> <p> 2 安裝過(guò)緊。觀察機(jī)械密封的動(dòng)靜環(huán)平面，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(guò)緊造成的。處理辦法：調(diào)整安裝高度，葉輪安裝后，用螺絲刀拔動(dòng)彈簧，彈簧有較強(qiáng)的張力，松開(kāi)后即復(fù)λ，有2-4MM的移動(dòng)距離即可。 </p> <p> 3 安裝過(guò)松。觀察機(jī)封動(dòng)、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(wú)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(dòng)造成。 </p><p> 如何進(jìn)行水泵機(jī)械密封的選型及機(jī)械密封的安裝和使用水泵機(jī)械密封件屬于精密、結(jié)構(gòu)較為復(fù)雜的機(jī)械基礎(chǔ)元件之一，是各種泵類(lèi)、反應(yīng)合成釜、透平壓縮機(jī)、潛水電機(jī)等設(shè)備的關(guān)鍵部件。其密封性能和使用壽命取決于許多因素，如選型、機(jī)器的精度、正確的安裝使用等。 </p> <p> 一、水泵機(jī)械密封的安裝與使用要求 </p> <p> 1、機(jī)械密封對(duì)機(jī)器精度的要求(以泵用機(jī)械密封為例) </p> <p> (1)安裝機(jī)械密封部位的軸(或軸套)的徑向跳動(dòng)公差比較大不超過(guò)0.04～0.06MM。 </p> <p> (2)轉(zhuǎn)子軸向竄動(dòng)不超過(guò)0.3MM。 </p> <p> (3)密封腔體與密封端蓋結(jié)合的定位端面對(duì)軸(或軸套)表面的跳動(dòng)公差比較大不超過(guò)0.04～0.06MM。 </p> <p> 2、水泵機(jī)械密封的確認(rèn) </p> <p> (1)確認(rèn)所安裝的密封是否與要求的型號(hào)一致。 </p> <p> (2)安裝前要仔細(xì)地與總裝圖對(duì)照，零件數(shù)量是否齊全。 </p> <p> (3)采用并圈彈簧傳動(dòng)的機(jī)械密封，其彈簧有左、右旋之分，須按轉(zhuǎn)軸的旋向來(lái)選擇。機(jī)械密封的輔助沖洗系統(tǒng)是非常重要的，它可以有效的保護(hù)密封面，起到冷卻、潤(rùn)滑、沖走雜物等作用。</p><div style="width:100%;text-align: center;"><img style="max-width:
