<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,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、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、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，南京軸承密封購(gòu)買(mǎi)價(jià)格。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)，南京軸承密封購(gòu)買(mǎi)價(jià)格，南京軸承密封購(gòu)買(mǎi)價(jià)格。影響密封的主要因素有哪些？密封本身質(zhì)量、工藝操作條件、裝配安裝精度、主機(jī)本身精度、密封輔助系統(tǒng)。南京軸承密封購(gòu)買(mǎi)價(jià)格</p><div

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)。南京機(jī)械密封批發(fā)價(jià)當(dāng)動(dòng)、靜環(huán)之間的壓力增大或者液體在摩擦面上形成液膜的能力較差時(shí)，液體將從間隙中被擠出。</p><div

</p> <p> 泵用機(jī)械密封種類(lèi)繁多，型號(hào)各異，但泄漏點(diǎn)主要有五處： </p> <p> ● 軸套與軸間的密封； </p> <p> ● 動(dòng)環(huán)與軸套間的密封； </p> <p> ● 動(dòng)、靜環(huán)間密封； </p> <p> ● 對(duì)靜環(huán)與靜環(huán)座間的密封； </p> <p> ● 密封端蓋與泵體間的密封。 </p> <p> 安裝靜試時(shí)泄漏 </p> <p> 機(jī)械密封安裝調(diào)試好后，一般要進(jìn)行靜試，觀察泄漏量。如泄漏量較小，多為動(dòng)環(huán)或靜環(huán)密封圈存在問(wèn)題；泄漏量較大時(shí)，則表明動(dòng)、靜環(huán)摩擦副間存在問(wèn)題。 </p> <p> 在初步觀察泄漏量、判斷泄漏部位的基礎(chǔ)上，再手動(dòng)盤(pán)車(chē)觀察，若泄漏量無(wú)明顯變化則靜、動(dòng)環(huán)密封圈有問(wèn)題；如盤(pán)車(chē)時(shí)泄漏量有明顯變化則可斷定是動(dòng)、靜環(huán)摩擦副存在問(wèn)題；此外，泄漏通道也可同時(shí)存在，但一般有主次區(qū)別，只要觀察細(xì)致，熟悉結(jié)構(gòu)，一定能正確判斷。 </p><p> 安裝環(huán)節(jié)造成的漏水現(xiàn)象 </p> <p> <br /> </p> <p> 安裝環(huán)節(jié)的施工不當(dāng)也可能造成密封損害。 </p> <p> <br /> </p> <p> 如在機(jī)械密封中起軸向定位作用的內(nèi)六角螺釘若安裝不緊，就會(huì)使密封發(fā)生軸向竄動(dòng)，當(dāng)竄動(dòng)量過(guò)大，壓縮彈簧不能使靜止環(huán)緊貼在旋動(dòng)環(huán)上時(shí)，就會(huì)導(dǎo)致泄漏;環(huán)密封圈的軸端面及安裝靜環(huán)密封圈的密封壓蓋端面不夠光潔，可能使旋動(dòng)環(huán)和靜止環(huán)在安裝時(shí)受損;而機(jī)械密封的彈簧壓縮量也是安裝的重點(diǎn)，一旦誤差應(yīng)>±2 mm，就可能因壓縮量過(guò)大導(dǎo)致端面比壓和摩擦熱量的增加，使端面的磨損和熱變形加劇，或因壓縮量過(guò)小造成靜止環(huán)端面的比壓不足，影響密封效果。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 style="width:100%;text-align: center;"><img
