,介質(zhì)流動(dòng)通過內(nèi)外空間的交界面即密封面發(fā)生泄漏。造成泄漏的根本原因是由于接觸面上存在間隙，而接觸面兩側(cè)的壓力差、濃度差則是泄漏的推動(dòng)力。由于密封面形式及加工精度等因素的影響，密封面上存在間隙在所難免，這就會(huì)造成密封面不完全吻合，從而發(fā)生泄漏。要減少泄漏，就必須使接觸面很大程度地嵌合，即減小泄漏通道的截面積，增加泄漏阻力，并使之大于泄漏推動(dòng)力。

彈簧壓縮量越大密封效果越好其實(shí)不然，彈簧壓縮量過大，可導(dǎo)致摩擦副急劇磨損，瞬間燒損;過度的壓縮使彈簧失去調(diào)節(jié)動(dòng)環(huán)端面的能力，導(dǎo)致密封失效。2、動(dòng)環(huán)密封圖越緊越好其實(shí)動(dòng)環(huán)密封圈過緊有害無益。一是加劇密封圈與軸套間的磨損，過于早漏;二是增大了動(dòng)環(huán)軸向調(diào)整、移動(dòng)的阻力，在工況變化頻繁時(shí)無法適時(shí)進(jìn)行調(diào)整;三是彈簧過度疲憊易損壞;四是使動(dòng)環(huán)密封圈變形，影響密封效果。 3、靜環(huán)密封圈越緊越好靜環(huán)密封圈基本處于靜止?fàn)顟B(tài)，相對(duì)較緊密封效果會(huì)好些，但過緊也是有害的。一是引起靜環(huán)密封因過度變形，影響密封效果;二是靜環(huán)材質(zhì)以石墨居多，一般較脆，過度受力極易引起碎裂;三是安裝、拆卸困難，極易損壞靜環(huán)。蘇州電動(dòng)泵密封的用途和特點(diǎn)泵用機(jī)械密封經(jīng)過靜試后，運(yùn)轉(zhuǎn)時(shí)高速旋轉(zhuǎn)產(chǎn)生的離心力，會(huì)阻擋介質(zhì)的泄漏。</p><div

<p> 目前，使用技術(shù)一般有三類，采用無泄漏泵如屏蔽泵、磁力泵、隔膜泵等，對(duì)于必須使用離心泵時(shí)，采用雙重機(jī)械密封或干氣密封?；旧洗蟛糠诌m用雙封的場(chǎng)合都可以使用干氣密封，在技術(shù)上來講都是可行的。 </p> <p>

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)。

高溫?zé)嵊捅弥饕谐５妆?、減底泵、催化油漿泵，該類泵的特點(diǎn)是溫度高（370℃-400℃）、油品粘度大、塔底有雜質(zhì)。我們針對(duì)高溫泵的這些特點(diǎn)采用的是YH-609系列機(jī)械密封, 結(jié)構(gòu)選型主要結(jié)合了以下幾個(gè)方面: </p> <p> 金屬波紋管旋轉(zhuǎn)結(jié)構(gòu) </p> <p> 旋轉(zhuǎn)波紋管密封在旋轉(zhuǎn)離心力作用下可以自身清洗波紋管，減少波紋管**沉積和內(nèi)側(cè)結(jié)焦，并能防止因急冷造成的波紋管變形。泵類設(shè)備轉(zhuǎn)速一般為2950r/min，機(jī)械密封線速度遠(yuǎn)小于25m/s,因此，可以選用旋轉(zhuǎn)結(jié)構(gòu)。 </p> <p> 密封結(jié)構(gòu)形式采用開槽斜面擠緊軸套 </p> <p> 這種定位傳動(dòng)可靠，安裝拆卸方便且不傷軸。并設(shè)置有限位板，便于泵外調(diào)整密封的壓縮量。波紋管內(nèi)徑一處設(shè)一45℃斜角，以分散應(yīng)力，延長波紋管壽命。輔助密封采用柔性石墨替代合成橡膠，可以承受高達(dá)425℃的高溫。 </p> <p> 摩擦副材料的選取 </p> <p> 對(duì)摩擦副材料的選取我們采用“硬對(duì)硬”結(jié)構(gòu)，起初動(dòng)靜環(huán)我們選擇了SiC-WC，但是運(yùn)轉(zhuǎn)一段時(shí)間發(fā)現(xiàn)動(dòng)環(huán)出現(xiàn)肯邊現(xiàn)象。改用YG6-YG6之后，設(shè)備運(yùn)轉(zhuǎn)一直正常。 </p> <p> <br />
