第二種冷卻方式在第一種冷卻形式的基礎(chǔ)上在靜環(huán)的背部增加一冷卻水套，冷卻效果有所改善，并可以沖洗，收集泄露出來(lái)的液體。當(dāng)密封介質(zhì)溫度＞150℃時(shí)除了在冷卻水套中通過(guò)冷卻水及靜環(huán)背部冷卻外，應(yīng)采取強(qiáng)制冷卻措施。即從泵出口的干凈介質(zhì)應(yīng)預(yù)先經(jīng)熱交換器冷卻至50℃時(shí)。再進(jìn)入密封腔冷卻沖洗，該形式是冷卻效果**良好的一種。 </p> <p> 如介質(zhì)中含有顆粒或雜質(zhì)，必須采用過(guò)濾措施，把常溫干凈沖洗液輸入密封腔內(nèi)。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。</p><div style="width:100%;text-align:

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(mǎn)足了現(xiàn)場(chǎng)要求。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。常州清水密封生產(chǎn)企業(yè)</p><p
