style="text-indent:25px">污水處理工程是環(huán)境保護(hù)的重要項(xiàng)目，而污水泵作為污水處理工程的主要配套設(shè)備被廣泛應(yīng)用于城市排污、礦山、冶金、電力以及石化等污水處理作業(yè)，發(fā)展前景廣闊。污水泵產(chǎn)品除了要求技術(shù)性能好之外，密封是污水泵的關(guān)鍵，必須可靠性高，污水泵無(wú)故障運(yùn)行時(shí)間長(zhǎng)。污水泵在工作中，密封一旦失效，外部介質(zhì)或油室中的油便會(huì)進(jìn)入電機(jī)腔，引起潛水電機(jī)缺相、短路、漏電、燒壞電機(jī)，甚至影響人身安全。因此，為了進(jìn)一步提高污水泵使用的安全性、運(yùn)行可靠性以及提高污水泵無(wú)故障運(yùn)行時(shí)間，有必要對(duì)污水泵通常使用的機(jī)械密封進(jìn)行結(jié)構(gòu)分析，實(shí)行改進(jìn)。</p><p> 丁腈橡膠是常用的一種耐油橡膠。它是丁二烯和丙烯腈的共聚物。根據(jù)丙烯腈含量多少分成若干種：低丙烯腈（丁腈-18）、中丙烯腈（丁腈-26）和高丙烯腈（丁腈-40）、丙烯腈含量越高，它的耐油性越好，抗張強(qiáng)度、硬度和耐磨性、耐水性增加，透氣性減小。隨之而來(lái)，它在極性溶劑中是溶解度卻增大，耐腐蝕性也受到影響，彈性和耐寒性也變差。丁腈橡膠不耐撓曲，抗撕裂也較差。<span style="font-size:12px;">O形圈是相對(duì)來(lái)說(shuō)比較流行的密封件，主要用于靜態(tài)密封應(yīng)用中（這意味著在密封表面之間或在密封表面與其配合表面之間沒(méi)有運(yùn)動(dòng)）。Seals-Shop提供的O形圈的橫截面范圍為0.8到8.4 mm，內(nèi)徑較大程度為810 mm。O形圈可用于密封幾乎所有的液體和氣體介質(zhì)，并且可用彈性體和其他材料制成，包括乙丙二烯單體（EPDM）橡膠，含氟彈性體（FKM）和丁腈橡膠（NBR）。</span> 填料密封按其結(jié)構(gòu)特點(diǎn)可分為：軟填料密封硬填料密封成型填料密封。</p><div style="width:100%;text-align: center;"><img

油封，即潤(rùn)滑油的密封。它常用于各種機(jī)械的軸承處，特別是轉(zhuǎn)動(dòng)軸承部位。其功能在于把油腔和外界隔離，對(duì)內(nèi)封油，對(duì)外封塵。 </p> <p> 油封與其他密封比較有下列優(yōu)點(diǎn)： </p> <p> 油封重量輕，耗材少。 </p> <p> 油封的安裝位置小，軸向尺寸小，輕易加工。 </p> <p> 密封性能好，使用壽命較長(zhǎng)，對(duì)機(jī)器的振動(dòng)和主軸的偏心都有一定的適應(yīng)性。 </p> <p> 拆卸輕易，檢驗(yàn)方便。 </p> <p> 價(jià)格便宜。 </p> <p> 防塵密封 </p> <p> 油封可作防塵密封件的使用。但是在粉塵嚴(yán)重或是為了保護(hù)其他密封件時(shí)，經(jīng)常使用專門的防塵密封。 </p> <p> 防塵密封的材料，油壓機(jī)械多用橡膠，氣壓機(jī)械多用毛氈，飛機(jī)和冷帶工作的油缸為了對(duì)付活塞桿外部結(jié)冰而用金屬，化工部分為防止活塞桿上的粘著物也用金屬。 </p> <p> 防塵密封對(duì)保護(hù)關(guān)鍵性的液壓設(shè)備是十分重要的。滲透塵土，不僅磨損密封件，而且會(huì)很大程度上的磨損導(dǎo)向套和活塞桿。此外，雜質(zhì)進(jìn)進(jìn)液壓介質(zhì)中，也會(huì)影響操縱閥和泵的功能，在壞的情況下，也可能損壞這些裝置。防塵圈能除掉活塞桿表面上的塵土和雜物，但損壞活塞桿上的油膜，這對(duì)密封件的潤(rùn)滑也有一定作用。江蘇軸承密封市場(chǎng)批發(fā)價(jià)格</p><p>
