2非金屬環(huán)腐蝕石墨環(huán)被腐蝕也是機(jī)械密封是小的重要原因之一，斷面溫度過高、浸漬樹脂選擇不當(dāng)、浸漬樹脂深度不夠等都是導(dǎo)致石墨環(huán)被腐蝕的原因。當(dāng)石墨環(huán)處于氧化性介質(zhì)中時，出冷卻不良或產(chǎn)生摩擦?xí)r，環(huán)境產(chǎn)生三四百度會促使石墨與氧化性介質(zhì)發(fā)生氧化反應(yīng)，使端面變得失去性能。3輔助密封圈及接觸部位的腐蝕不同的材料有不同的抗腐蝕性，輔助密封圈的材料一般選取具有彈性的橡膠，而橡膠被腐蝕后會使表面變得異常粗糙，失去原有的彈性。并且橡膠的耐高溫性能比較差，一般不超過兩百度。與輔助密封圈相接觸的部位處于相對靜止的狀態(tài)，二者之間的縫隙以及摩擦等都會是腐蝕產(chǎn)生的原因，并且腐蝕面一般較寬、較深。機(jī)泵機(jī)械密封的故障表現(xiàn)生產(chǎn)過程中，機(jī)泵機(jī)械密封泄露的原因有其本身的原因及外部原因，材料的選擇以及安裝方式和使用方式都會引起機(jī)械密封的失效，失效時的故障表現(xiàn)也各有差異，學(xué)會通過不同故障表現(xiàn)并做出正確及時的判斷能夠?qū)?shí)際生產(chǎn)提供強(qiáng)有力的支持。1靜壓實(shí)驗(yàn)時泄露機(jī)械密封裝置在安裝時由于員工不細(xì)心，經(jīng)常會使密封端面被碰傷以至于變形和損壞，清理不夠徹底，使得機(jī)械密封夾有顆粒狀雜質(zhì)。西藏機(jī)械密封件銷售蘇州輕型機(jī)械密封件。</p><div

消除泵振動措施有：泵、電機(jī)、底座、現(xiàn)場管路等輔助設(shè)備在現(xiàn)場安裝時，要嚴(yán)格把關(guān)，消除振動源。（二）泵軸的撓度偏大軸彎曲變形時橫截面形心沿與軸線垂直方向的線位移稱為撓度，機(jī)械密封要求兩個密封端面之間受力均勻。但由于泵產(chǎn)品設(shè)計的不合理，在機(jī)械密封安裝處產(chǎn)生的撓度偏大，使密封處受力不均勻，從而失去密封效果。這種現(xiàn)象大多存在臥式多級離心泵中。（三）泵軸的軸向竄量機(jī)械密封的密封面要有一定的比壓（～），從而達(dá)到密封的目的，兩端面的緊密緊密程度可以通過彈簧調(diào)節(jié)。為了保證這個比壓，要求泵軸不能有太大的竄量（≤），但在實(shí)際生產(chǎn)中，往往泵軸產(chǎn)生很大的竄量。對機(jī)械密封的使用非常不利的，這種情況在我分廠表現(xiàn)在泵啟動過程中，由于不平衡軸向力的存在，使整個軸發(fā)生向吸入口的竄動，造成機(jī)械密封失去密封作用，常用的措施有：葉輪上開平衡孔，泵體上裝平衡管等。</p><p> 壓縮量過小動靜環(huán)端面比壓不足，則不能密封。（2）安裝動環(huán)密封圈的軸（或軸套）端面及安裝靜環(huán)密封圈的密封壓蓋（或殼體）的端面應(yīng)倒角并修光，以免裝配時碰傷動靜環(huán)密封圈。十一、機(jī)封正常運(yùn)行和維護(hù)問題1、啟動前的準(zhǔn)備工作及注意事項(xiàng)a***檢查機(jī)械密封，以及附屬裝置和管線安裝是否齊全，是否符合技術(shù)要求。b機(jī)械密封啟動前進(jìn)行靜壓試驗(yàn)，檢查機(jī)械密封是否有泄漏現(xiàn)象。若泄漏較多，應(yīng)查清原因設(shè)法消除。如仍無效，則應(yīng)拆卸檢查并重新安裝。一般靜壓試驗(yàn)壓力用2-3公斤/平方厘米。c按泵旋向盤車，檢查是否輕快均勻。如盤車吃力或不動時，則應(yīng)檢查裝配尺寸是否錯誤，安裝是否合理。2、安裝與停運(yùn)a啟動前應(yīng)保持密封腔內(nèi)充滿液體。對于輸送凝固的介質(zhì)時，應(yīng)用蒸氣將密封腔加熱使介質(zhì)熔化。啟動前必須盤車，以防止突然啟動而造成軟環(huán)碎裂。b對于利用泵外封油系統(tǒng)的機(jī)械密封，應(yīng)先啟動封油系統(tǒng)。停車后停止封油系統(tǒng)。c熱油泵停運(yùn)后不能馬上停止封油腔及端面密封的冷卻水，應(yīng)待端面密封處油溫降到80度以下時，才可以停止冷卻水，以免損壞密封零件。3、運(yùn)轉(zhuǎn)a泵啟動后若有輕微泄漏現(xiàn)象，應(yīng)觀察一段時間。如連續(xù)運(yùn)行4小時，泄漏量仍不減小，則應(yīng)停泵檢查。b泵的操作壓力應(yīng)平穩(wěn)。張家港109-55機(jī)械密封件。</p><div
