設(shè)計(jì)上的缺點(diǎn)； </p> <p> 缺少培訓(xùn)/技術(shù)； </p> <p> 在我們拆卸機(jī)械密封的之前，我們先要想好以下幾點(diǎn)： </p> <p> 主要的泄漏在哪里? </p> <p> 在外部件上是否有碎片？ </p> <p> 是否觀察到軸或旋轉(zhuǎn)的密封部件有偏心現(xiàn)象？ </p> <p> 有否與系統(tǒng)相關(guān)的震動(dòng)/噪音（如氣穴，接合錯(cuò)位）？ </p> <p> 在“泵”或密封是否存在局部的熱生成？ </p> <p> 在不同的情況下泄漏是否是間歇的，如在不同的溫度下？ </p> <p> 屬何種泄漏，噴射，小滴，水流或流往管道？ </p> <p> 軸承是否有軸向間隙？ </p> <p> 如果是雙端面密封，則檢查隔離液供應(yīng)是否完好。 </p> <p> 密封在軸上的相對(duì)位置？ </p><p> 填料密封的原理 </p> <p> 在機(jī)械行業(yè)中填料密封主要用作動(dòng)密封,常用作離心泵、壓縮機(jī)、真空泵、攪拌機(jī)的轉(zhuǎn)軸密封。填料裝入填料腔以后,經(jīng)壓蓋螺絲對(duì)它作軸向壓縮,當(dāng)軸與填料有相對(duì)運(yùn)動(dòng)時(shí),由于填料的塑性,使它產(chǎn)生徑向力,并與軸緊密接觸。與此同時(shí),填料中浸漬的潤(rùn)滑劑被擠出,在接觸面之間形成油膜。由于接觸狀態(tài)并不是特別均勻的,接觸部位便出現(xiàn) </p> <p> 邊界潤(rùn)滑狀態(tài),稱為”軸承效應(yīng)”;而未接觸的凹部形成小油槽,有較厚的油膜,接觸部位與非接觸部位組成一道不規(guī)則的迷宮,起阻止液流泄漏的作用,此稱”迷宮效應(yīng)”。這就是填料密封的機(jī)理。良好的密封在于維持“軸承效應(yīng)”和”迷宮效應(yīng)”。也就是說,要保持良好的潤(rùn)滑和適當(dāng)?shù)膲壕o，若潤(rùn)滑不良,或壓得過緊都會(huì)使油膜中斷,造成填料與軸之間出現(xiàn)干摩擦,而后導(dǎo)致燒軸和出現(xiàn)嚴(yán)重磨損。因此,我們需要經(jīng)常對(duì)填料的壓緊程度進(jìn)行調(diào)節(jié),使填料中的潤(rùn)滑劑在運(yùn)行一段時(shí)間而有所流失之后,再擠出一些潤(rùn)滑劑,同時(shí)補(bǔ)償填料因體積變化所造成的壓緊力松弛。當(dāng)然這樣經(jīng)常擠壓填料,而后將使浸漬劑枯竭,所以定期更換填料是必要的。此外,為了維持液膜和帶走摩擦熱,有意讓填料處有少量泄漏也是必要的。人們?cè)诜治鰴C(jī)械密封泄漏原因時(shí)，在機(jī)械封自身方面查找原因，比如：它的選型如是否合適，材料選擇是否正確。</p><div

機(jī)械密封彈簧壓縮量調(diào)試時(shí)有哪些要求？答：機(jī)械密封彈簧唄傳動(dòng)螺釘壓縮一個(gè)量，叫彈簧的壓縮量。機(jī)械密封全部安裝完畢，相對(duì)于彈簧又壓縮一個(gè)量，這個(gè)量稱機(jī)械密封壓縮量。機(jī)械密封彈簧總的壓縮量是傳動(dòng)螺釘壓縮量和彈簧自身彈力之和。在裝配時(shí)，機(jī)械密封壓縮量越大，彈簧對(duì)動(dòng)環(huán)的作用力越小。因此，機(jī)械密封工作原理，彈簧的大小對(duì)機(jī)械密封的性能和壽命影響很大，所以裝配一定要按技術(shù)要求來調(diào)整壓縮量。 </p> <p> <p> 靜環(huán)組件安裝時(shí)有哪些注意事項(xiàng)？答：1）將經(jīng)過檢查的靜環(huán)密封圈從靜環(huán)尾部套入，把靜環(huán)組件裝入壓蓋或密封腔。在任何情況下，都不得給機(jī)械密封零件或部件施加沖擊力。被壓面應(yīng)墊上干凈的紙板或布，以免損傷密封端面。2）組裝成旋轉(zhuǎn)型動(dòng)環(huán)組件或靜止型的靜環(huán)組件后，用手按動(dòng)補(bǔ)償環(huán)，檢查是否裝到位，是否靈活；彈性開口是否定位可靠。3）密封端面與軸或軸套中心線的垂直度是否符合要求。4）對(duì)靜止型機(jī)械密封，靜環(huán)組件的防轉(zhuǎn)銷引線要準(zhǔn)確，推進(jìn)靜環(huán)組時(shí)，組件的銷槽要對(duì)準(zhǔn)銷子，推進(jìn)到位后，要測(cè)量組件端面至密封腔某端面的距離，判斷是否安裝到位；5）擰螺栓壓緊端蓋時(shí)，要用力均勻、對(duì)稱，分幾次擰完，不可一次緊定，以免偏斜，甚至壓碎石墨環(huán)。

style="text-indent:25px">泵的密封對(duì)整個(gè)設(shè)備運(yùn)轉(zhuǎn)來說起著重要的作用，泵的密封系統(tǒng)泄漏將會(huì)嚴(yán)重影響到設(shè)備的正常運(yùn)轉(zhuǎn)。江蘇電動(dòng)泵密封供應(yīng)商</p><p> 機(jī)械密封在電廠水泵中的應(yīng)用改造 </p> <p> <p> 在新增的水泵中全部采用了機(jī)械密封，與原有水泵的盤根密封形成了鮮明的對(duì)比：（1）機(jī)械密封與盤根密封在密封性能上，機(jī)械密封要比盤根密封漏泄量小的多，*為盤根密封漏泄量的1%。（2）使用壽命長(zhǎng)，兩年以內(nèi)無需更換，以往盤根密封每60天左右就要進(jìn)行一次更換。（3）消耗功率較少同比盤根密封省電5%以上。（4）減少了軸或軸承的磨損。 </p> <p> 通過摸索對(duì)比先后將車間的兩臺(tái)循環(huán)水泵、兩臺(tái)射水泵、凝結(jié)水泵共6臺(tái)泵進(jìn)行了進(jìn)行密封改造。改造后均收到了良好的效果。 </p> <p> 循環(huán)水泵（20HBA）在未改為機(jī)械密封前，每年至少要更換4次油盤根，每次更換量在1公斤左右，市場(chǎng)價(jià)格30元.，由于盤根磨損所致3年左右需更換一根水泵軸及配套軸瓦，費(fèi)用在7000元左右，不計(jì)人工費(fèi)用每臺(tái)水泵每年消耗在2500元左右。而改為機(jī)械密封后費(fèi)用方面每臺(tái)泵的機(jī)械密封價(jià)格在600元左右，至少一個(gè)大修期在3年以上，由于摩擦阻力的降低使電耗每小時(shí)下降8度，全年節(jié)電在58000度，降低成本3萬元左右。因此機(jī)械密封于盤根密封相比優(yōu)勢(shì)十分明顯。
