否則其結(jié)晶體或者微粒會加速密封副的磨損，以及影響密封副磨損后的自動補(bǔ)償而發(fā)生泄漏。所以根據(jù)輸送介質(zhì)的性質(zhì)不僅要配置相應(yīng)的沖洗管路，更要安裝有監(jiān)控和調(diào)節(jié)功能的儀表和裝置，保證沖洗液的壓力和流量滿足設(shè)計(jì)要求，才能維持機(jī)封的正常工作，這一點(diǎn)往往被用戶所忽視。3、每種機(jī)械密封所能承受的壓力是有限度的，由于對密封腔內(nèi)的壓力測算不準(zhǔn)，造成密封腔內(nèi)的壓力超過了機(jī)械密封所能承受的壓力而產(chǎn)生泄漏，也是常見的密封失效原因之一。4、機(jī)械密封的工作溫度不能超過其規(guī)定值。在有冷卻管路的設(shè)計(jì)中，往往由于冷卻介質(zhì)的流量不足而使冷卻效果降低；在沒有冷卻管路的設(shè)計(jì)中，密封腔內(nèi)經(jīng)常由于窩存空氣而造成機(jī)械密封處于干磨擦狀態(tài)。這兩種情況都會使機(jī)械密封的運(yùn)動密封副工作溫度過高而加快磨損，導(dǎo)致密封失效。5、在使用單彈簧的機(jī)械密封時(shí)，忽略彈簧的旋轉(zhuǎn)方向與泵轉(zhuǎn)子轉(zhuǎn)動方向的正確組合也時(shí)有發(fā)生?；蛟O(shè)計(jì)時(shí)沒有說明，或裝配時(shí)的疏忽，沒有做到因?yàn)檗D(zhuǎn)子的旋轉(zhuǎn)而使機(jī)械密封的彈簧力加大而是相反，結(jié)果造成動環(huán)和靜環(huán)磨擦副的壓力不足而形成泄漏。6、軸承的嚴(yán)重磨損或損壞，使泵軸產(chǎn)生嚴(yán)重的軸向竄動，也是機(jī)械密封泄漏的原因之一。隨著科學(xué)的技術(shù)的發(fā)展。</p><p> 機(jī)封的安裝位置隨機(jī)械密封型式、吸沙泵種類的不同而不同。安裝時(shí)注意事項(xiàng)1、在安裝、拆卸機(jī)械密封時(shí)要仔細(xì)，嚴(yán)禁動用手錘和扁鏟，以免損壞密封元件。如果結(jié)垢拆卸不下時(shí)，應(yīng)清洗干凈后再進(jìn)行拆卸。2、如果在泵兩端都用機(jī)械密封時(shí)，在裝配，拆卸過程中互相照顧，防止顧此失彼。3、對運(yùn)行過的機(jī)械密封，凡有壓蓋松動使密封發(fā)生移動的情況，則動靜環(huán)零件必須更換，不應(yīng)重新上緊繼續(xù)使用。因?yàn)樗蓜雍竽Σ粮痹瓉磉\(yùn)轉(zhuǎn)軌跡會發(fā)生變動，接觸面的密封性就很容易遭到破壞。吸沙泵啟動前的準(zhǔn)備工作1、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。2、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。3、按吸沙泵的轉(zhuǎn)動方向旋轉(zhuǎn)泵軸，檢查是否輕快均勻。如旋轉(zhuǎn)吃力或不動時(shí)，則應(yīng)檢查裝配尺寸是否錯(cuò)誤，安裝是否合理。吸沙泵運(yùn)轉(zhuǎn)時(shí)注意事項(xiàng)1、吸沙泵啟動后若有輕微泄漏現(xiàn)象，應(yīng)觀察一段時(shí)間。如連續(xù)運(yùn)行4小時(shí)，泄漏量仍不減小，則應(yīng)停泵檢查。2、吸沙泵的操作壓力應(yīng)平穩(wěn)，壓力波動不大于1公斤/平方厘米。3、吸沙泵在運(yùn)轉(zhuǎn)中。山西格蘭富機(jī)械密封型號大全。</p><div
