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)盤車觀察，若泄漏量無(wú)明顯變化則靜、動(dòng)環(huán)密封圈有問(wèn)題；如盤車時(shí)泄漏量有明顯變化則可斷定是動(dòng)，蘇州輕型機(jī)械密封制造廠家、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，蘇州輕型機(jī)械密封制造廠家，只要觀察細(xì)致，熟悉結(jié)構(gòu)，一定能正確判斷，蘇州輕型機(jī)械密封制造廠家。

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。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。 </p><p style="text-indent:25px">由于磁性過(guò)濾器堵塞對(duì)機(jī)械密封的正常運(yùn)行使用危害很大，因此要定期檢查清洗，發(fā)現(xiàn)元件損壞及時(shí)更換;應(yīng)保持機(jī)械密封水一路磁性濾網(wǎng)運(yùn)行，另一路備用，定期切換使用，以保證其正常的運(yùn)行狀態(tài)。定期清理工作結(jié)束，應(yīng)在進(jìn)行注水排空氣后，再將磁性過(guò)濾器投入備用狀態(tài)。機(jī)械密封水系統(tǒng)的排氣管必須在高于換熱器機(jī)械密封水出口管路上加裝，正常運(yùn)行前必須將機(jī)械密封水腔室及管路中的空氣徹底排出，低轉(zhuǎn)速運(yùn)行時(shí)也可以排氣，但是注意掌握開度不要將排氣閥全開。如排氣不徹底會(huì)出現(xiàn)密封摩擦副之間沒(méi)有潤(rùn)滑液，造成干磨和旋動(dòng)環(huán)熱裂，嚴(yán)重影響機(jī)械密封的安全正常運(yùn)行。此外，針對(duì)使用中的壓力問(wèn)題，除在安裝時(shí)嚴(yán)格執(zhí)行規(guī)定的彈簧壓縮量外，還應(yīng)在高壓條件下采取特別處理措施。為使端面受力合理、減小變形，可采用硬質(zhì)合金、陶瓷等耐壓強(qiáng)度高的材料，并加強(qiáng)冷卻的潤(rùn)滑措施。對(duì)真空狀態(tài)運(yùn)行造成的機(jī)械密封滲漏，應(yīng)采用雙端面機(jī)械密封，以改善潤(rùn)滑條件，提高密封性能。化工泵在與運(yùn)轉(zhuǎn)時(shí)，副葉輪所產(chǎn)生的壓頭平衡了主葉輪出口高壓液體，從而實(shí)現(xiàn)密封。</p><div
