為保證機(jī)械密封在高溫環(huán)境下正常工作，可以采取如下措施。 </p> <p> 給機(jī)封增加冷卻沖洗裝置。 </p> <p> 選擇耐高溫的材料，江蘇離心泵密封廠家批發(fā)，根據(jù)不同的工作溫度選用不同的材料。丁腈橡膠溫度上限為80℃，硅橡膠和氟橡膠為200℃，聚四氟乙烯為250℃，江蘇離心泵密封廠家批發(fā)。另外，機(jī)械密封中的非金屬摩擦副多采用石墨浸漬材料制成，所以也要根據(jù)不同的工作溫度選用不同種類的浸漬石墨。一般浸巴氏合金石墨適用溫度范圍小于150℃，浸樹脂石墨適用溫度范圍為170~200℃，浸銅、鋁、鉛的石墨可在小于400℃的工作條件下使用。動(dòng)環(huán)組件應(yīng)盡可能選用膨脹系數(shù)相近的材料，以防止高溫下動(dòng)環(huán)和動(dòng)環(huán)座的連接松動(dòng)。 </p> <p> 選擇金屬波紋管機(jī)械密封。金屬波紋管密封近年來(lái)在高溫密封中使用很多，并且取得了很好的效果。在該種機(jī)封中，江蘇離心泵密封廠家批發(fā)，金屬波紋管取代了普通機(jī)封中的彈簧，省去了動(dòng)環(huán)輔助密封圈，不需要克服動(dòng)環(huán)補(bǔ)償時(shí)與轉(zhuǎn)軸的摩擦和磨損，因此在高溫下使用，一般都能取得不錯(cuò)的效果。 </p> <p> <br /> 密封面合理的間隙，機(jī)械密封的平衡程度，密封端面液膜的閃蒸都是造成端面打開(kāi)而使固體顆粒進(jìn)入的主要原因。江蘇離心泵密封廠家批發(fā)</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

油封的骨架和彈簧是金屬制作，密封唇口等主要部分為橡膠。油封根據(jù)使用環(huán)境，可以用不同的橡膠進(jìn)行生產(chǎn)，以滿足密封的性能和要求。**常用的耐油橡膠是丁腈橡膠，丁腈橡膠為目前油封及O型圈使用**普遍的橡膠之一。 </p> <p> <span style="font-size:12px;">可說(shuō)是目前用途**廣、成本比較低的橡膠密封件。制造油封常用的還有聚丙酸酯橡膠、硅橡膠、氟橡膠和聚四氟乙烯等。各種橡膠的性能請(qǐng)參見(jiàn)：主要橡膠的種類與特長(zhǎng)。 </span> </p> <p> <span style="font-size:12px;"> </span> </p> <p> 油封所使用的場(chǎng)合，其適用的密封介質(zhì)一般是礦物潤(rùn)滑油、潤(rùn)滑脂和合成潤(rùn)滑油、潤(rùn)滑脂。另外也可密封工業(yè)生產(chǎn)中使用的DIN51524液壓油類，VDMA24317以及VDMA24320高阻燃液壓油類，低潤(rùn)滑特性的硅油類。在特殊情況下也可密封潤(rùn)滑性低的酸類，堿類，有機(jī)溶劑類等腐蝕性介質(zhì)。 </p> <p> <span style="font-size:12px;">通常采用氟橡膠材料的油封其耐腐蝕性，耐高溫性都要比NBR材質(zhì)的好，在無(wú)潤(rùn)滑、純干燥和多介質(zhì)的條件下建議采用PTFE密封唇制作的油封，其密封唇有足夠的潤(rùn)滑能力，降低唇緣的磨損。單個(gè)油封不宜密封兩種不同的介質(zhì)，大量的化學(xué)物質(zhì)增加了對(duì)于油封材質(zhì)性能的影響，油封對(duì)密封介質(zhì)的相容性應(yīng)該通過(guò)實(shí)驗(yàn)室試驗(yàn)來(lái)確定。</span> </p> <br /> <p> <br /> 江蘇離心泵密封廠家批發(fā)摩擦副所用的材料耐磨性差、摩擦系數(shù)大、端面比壓（包括彈簧比壓）過(guò)大等,都會(huì)縮短機(jī)械密封的使用壽命。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height:

在分析泵用機(jī)械密封泄漏時(shí)，不*要考慮機(jī)械密封的內(nèi)因，而且要考慮機(jī)械密封的外因。在實(shí)際工作中要注意以下幾個(gè)問(wèn)題： </p> <p>

維修工應(yīng)增加對(duì)機(jī)械密封輔助系統(tǒng)的重要作用和認(rèn)識(shí)，盡可能配備完善的機(jī)械密封輔助系統(tǒng)，以提高密封效果。 </p> <p> 在分析機(jī)械密封泄漏的原因時(shí)，要充分考慮到泵的其它零部件對(duì)機(jī)械密封運(yùn)行的影響，采取措施不斷提高機(jī)械密封的效果。 </p><p> 潛污泵的作用是將污水中的雜質(zhì)通過(guò)的方式處理。然后排放掉，與清水泵的不同之處使其技術(shù)要求也不同于普通類型的設(shè)備，它的設(shè)計(jì)需要考慮到效率、磨損以及特殊環(huán)境：（1）導(dǎo)板等部件自動(dòng)與著脫耦合，耦合牢固可靠。（2）引出電纜應(yīng)采用YZW和YCW型橡套電纜或性能相同的電纜，且電纜的密封需采用水密頭式密封，確保潛污泵在使用過(guò)程中不至于發(fā)生泄露。（3）葉輪：葉輪設(shè)計(jì)成無(wú)堵塞型式，葉輪皆經(jīng)過(guò)靜平衡試驗(yàn)。葉輪材質(zhì)為HT200, 符合GB9439-88的要求，過(guò)流表面光潔無(wú)粘砂、尖角、冷隔、氣孔、砂眼等缺點(diǎn)。（4）主軸材質(zhì)選用3Cr13經(jīng)調(diào)質(zhì)處理，有效地、可靠地傳遞動(dòng)力。主軸與葉輪用鍵連接，以傳遞動(dòng)力。主軸與葉輪用葉輪螺母鎖緊并有止退墊片，可防止水泵倒轉(zhuǎn)，造成葉輪松脫。（5）密封環(huán)：材質(zhì)鑄造青銅，防止因銹蝕而與葉輪咬死。設(shè)有密封環(huán)可更大限度地減少內(nèi)部泄露，提高水泵的效率。（6）機(jī)械密封：采用兩套單端面非平衡型機(jī)械密封。油腔和電機(jī)室之間的上部密封單元由陶瓷，石墨組成；泵殼和油腔之間的下部密封單元由碳化硅，碳化硅組成，以防接觸介質(zhì)。 </p> <p> <br /> 各種密封其性能影響因素是不同的，如機(jī)械密封(填料密封等)影響因素有溫度、介質(zhì)、磨損、所承受壓力等。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="江蘇離心泵密封廠家批發(fā),封"

強(qiáng)酸強(qiáng)堿介質(zhì)具有較強(qiáng)的腐蝕性，且易結(jié)晶，為了防止介質(zhì)對(duì)密封彈性元件的腐蝕，應(yīng)使彈性元件與介質(zhì)隔離，采用外裝結(jié)構(gòu)，第3 種布置方式(背靠背或面對(duì)面)。O 形圈材料選用耐腐蝕的氟橡膠或全氟橡膠。動(dòng)靜環(huán)選用硬對(duì)硬(碳化鎢或碳化硅)配置。 </p> <p> 強(qiáng)酸強(qiáng)堿泵現(xiàn)場(chǎng)大多采用單端面密封，因而密封背面大多出現(xiàn)結(jié)晶結(jié)垢，對(duì)設(shè)備造成腐蝕等現(xiàn)象。為了避免該現(xiàn)象發(fā)生，使現(xiàn)場(chǎng)更加清潔，可直接選用PLAN54(見(jiàn)圖4)。煉油裝置中大多數(shù)酸泵或堿泵的入口壓力較低，基本為常壓，因此PLAN54 的沖洗源可直接用循環(huán)水。該方案雖然選用了雙端面密封，但從經(jīng)濟(jì)角度考慮*增加了一對(duì)摩擦副，沒(méi)有另外增加輔助系統(tǒng)，既節(jié)約了投資成本又滿足了現(xiàn)場(chǎng)要求。機(jī)械密封是依靠彈性元件對(duì)動(dòng)、靜環(huán)斷面的預(yù)緊力來(lái)對(duì)軸向端面進(jìn)行密封的，又稱為端面密封。浙江葉輪泵密封源頭直供廠家</p><p

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>
