在新增的水泵中全部采用了機(jī)械密封，與原有水泵的盤(pán)根密封形成了鮮明的對(duì)比：（1）機(jī)械密封與盤(pán)根密封在密封性能上，機(jī)械密封要比盤(pán)根密封漏泄量小的多，*為盤(pán)根密封漏泄量的1%。（2）使用壽命長(zhǎng)，兩年以內(nèi)無(wú)需更換，以往盤(pán)根密封每60天左右就要進(jìn)行一次更換。（3）消耗功率較少同比盤(pán)根密封省電5%以上。（4）減少了軸或軸承的磨損。 </p> <p> 通過(guò)摸索對(duì)比先后將車間的兩臺(tái)循環(huán)水泵、兩臺(tái)射水泵、凝結(jié)水泵共6臺(tái)泵進(jìn)行了進(jìn)行密封改造。改造后均收到了良好的效果。 </p> <p> 循環(huán)水泵（20HBA）在未改為機(jī)械密封前，每年至少要更換4次油盤(pán)根，每次更換量在1公斤左右，市場(chǎng)價(jià)格30元.，由于盤(pán)根磨損所致3年左右需更換一根水泵軸及配套軸瓦，費(fèi)用在7000元左右，不計(jì)人工費(fèi)用每臺(tái)水泵每年消耗在2500元左右。而改為機(jī)械密封后費(fèi)用方面每臺(tái)泵的機(jī)械密封價(jià)格在600元左右，至少一個(gè)大修期在3年以上，由于摩擦阻力的降低使電耗每小時(shí)下降8度，全年節(jié)電在58000度，降低成本3萬(wàn)元左右。因此機(jī)械密封于盤(pán)根密封相比優(yōu)勢(shì)十分明顯。 </p> <p> <br /> </p> <p> <br /> </p> </p><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(lái)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(xiǎn)和潤(rùn)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(jì)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(rùn)滑，而且也可保證密封面達(dá)到一定的密封壓力。</span> 與密封件相對(duì)滑動(dòng)零件的幾何位置精度(同心度)高材質(zhì)好(如鍍硬鉻)和表面粗糙度較細(xì)可延長(zhǎng)使用壽命。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="常州管道泵密封廠家批發(fā),封"

<p> <span style="font-size:12px;">機(jī)械的摩擦部分由于在機(jī)械運(yùn)轉(zhuǎn)時(shí)有油進(jìn)入，為防止這些油從機(jī)械的間隙中泄漏而使用油封，并且除了油以外還需要防止水與化學(xué)藥液的泄漏以及塵埃及土砂從外部侵入，這時(shí)候也要用到油封。</span> </p> <p> <span style="font-size:12px;">油封的密封狀態(tài)，一是油封外緣和腔體之間為靜態(tài)密封，同時(shí)保證油封外緣在腔體之間的可靠定位。二是油封密封唇和軸之間的密封狀態(tài)，當(dāng)軸旋轉(zhuǎn)時(shí)為動(dòng)態(tài)密封，當(dāng)軸靜止時(shí)為靜態(tài)密封。各種影響因素的綜合作用及其相互作用，都對(duì)油封的密封性能和使用壽命產(chǎn)生了很大影響。</span>

在凝結(jié)過(guò)程中，由于體積急劇縮小，四周的液體以極大的速度沖向整個(gè)凝結(jié)空間，使泵內(nèi)造成沖擊振動(dòng)和噪音。在壓力很大、頻率很高的液體質(zhì)點(diǎn)連續(xù)沖擊下，金屬表面逐漸因疲勞而破壞，這種破壞稱為剝蝕。 </p> <p> 同時(shí)溶于液體中的氧等活潑氣體也使金屬產(chǎn)生腐蝕。由于化學(xué)腐蝕與機(jī)械剝蝕的共同作用，加快了金屬損壞的速度，從而使葉輪受到破壞，這就是汽蝕破壞，這種由于液體的汽化和凝結(jié)而產(chǎn)生的沖擊現(xiàn)象就稱為氣蝕現(xiàn)象。消除泵進(jìn)口氣蝕的措施有以下幾點(diǎn)： </p> <p>
