</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(guò)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，蘇州葉輪泵密封哪家質(zhì)量好。在任何情況下，蘇州葉輪泵密封哪家質(zhì)量好，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)。

在液泵的正常操作中，旋轉(zhuǎn)面和靜止面之間因填料盒中的液體所產(chǎn)生的壓力而使其保持在密封狀態(tài)，在起動(dòng)和停機(jī)時(shí)，填料盒的壓力由彈簧產(chǎn)生的壓力維持(甚至可以由彈簧的壓力來(lái)代替)。 </p> <p> 大部分機(jī)械密封的設(shè)計(jì)采用較軟的材料來(lái)制作旋轉(zhuǎn)面，使其在較硬的靜止面上旋轉(zhuǎn)摩擦。多年來(lái)，**通用的組合是利用碳材料作為旋轉(zhuǎn)面，使其在陶瓷靜止面上運(yùn)行。這類材料目前仍在普遍使用，但靜止面則選用不銹鋼或更硬的材料制作，例如碳化鎢或碳化硅。 </p> <p> 不管采用什么材料，總之在接觸面之間必須保持一層液體薄膜，以起到潤(rùn)滑的作用。然而，在填料盒內(nèi)，采用彈簧負(fù)載和液體壓力相結(jié)合的方式，可以使密封面之間起到很好的密封作用。但密封壓力太高，則會(huì)影響接觸面之間形成液體薄膜，導(dǎo)致熱量增加和過(guò)早的磨損。如果密封壓力太低，接觸面之間的間隙增大，容易造成液體泄漏。 </p> <p> 密封制造廠正在不斷地努力提高接觸面的平直度，他們采用特殊的拋光板進(jìn)行研磨。然后，采用單色光源的光柵板對(duì)其檢測(cè)。從這一觀點(diǎn)出發(fā)，對(duì)這些密封接觸面必須小心處理，并嚴(yán)格按照安裝說(shuō)明，保證密封面得到適當(dāng)?shù)谋Ｗo(hù)和正確就位，這一點(diǎn)是非常重要的。 </p> <p> <br /> </p> </p><p> 平衡和非平衡式密封 </p> <p> 機(jī)械密封的平衡對(duì)接觸面的密封壓力有很大影響。這一密封壓力取決于密封本身的有效截面以及填料盒內(nèi)的壓力。 </p> <p> <span style="font-size:12px;"> 非平衡型密封的旋轉(zhuǎn)面相反一側(cè)的截面完全暴露于填料盒的壓力范圍之下，這種情況會(huì)使密封面之間產(chǎn)生很高的密封壓力，從而會(huì)使工作溫度提高，加快磨損速度。在高溫工作條件下或液體具有較大腐蝕性和磨擦性的情況下，會(huì)極大降低機(jī)械密封的使用壽命。</span> </p> <p> <span style="font-size:12px;"> 對(duì)機(jī)械密封加以平衡，可降低密封壓力，延長(zhǎng)密封的使用壽命。一般采用帶有臺(tái)階的主軸和軸套，降低旋轉(zhuǎn)面的有效截面，就可達(dá)到上述目的。不過(guò)千萬(wàn)別將凈密封壓力調(diào)節(jié)到接近零的水平，因?yàn)檫@樣做的結(jié)果可能會(huì)造成密封面之間的工作狀況不穩(wěn)定，并可能會(huì)因突然的變故而將密封吹開。</span> </p> <p> <span style="font-size:12px;"> 解決這些密封問(wèn)題的答案也許是采用非平衡式密封，對(duì)于某些服務(wù)來(lái)說(shuō)，也許采用非平衡式密封能達(dá)到更好的效果。例如，在某些應(yīng)用領(lǐng)域，與密封的使用壽命相比，也許更強(qiáng)調(diào)對(duì)液體泄漏造成的安全性問(wèn)題。在這種情況下，對(duì)密封的選用也許可理解為更希望選擇具有較高的密封壓力。同樣，在選用較冷液體的密封時(shí)，操作溫度的增加也許是微不足道的。</span>

造成泄漏的原因主要有兩個(gè)方面：一是密封面上有間隙。二是密封部位兩側(cè)存在壓力差，消除或減小任何一個(gè)因素都可以阻止或減小泄漏，達(dá)到密封的目的。泵的設(shè)計(jì)壓力和使用壓力是客觀存在不能減小，所以泵的密封該解決的是消除或減小密封面之間的間隙。這種間隙包括密封面之間的間隙和密封裝置本生內(nèi)部的間隙。 </p> <p> <br /> 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(dòng)方向的正確組合也時(shí)有發(fā)生。蘇州葉輪泵密封經(jīng)銷廠家</p><p
