補(bǔ)償機(jī)構(gòu)中有多個(gè)彈簧的密封稱為多彈簧機(jī)械密封（圖5）；補(bǔ)償機(jī)構(gòu)中只有一個(gè)彈簧的機(jī)械密封稱為單彈簧機(jī)械密封（圖6），多彈簧機(jī)械密封又稱小彈簧機(jī)械密封，這種結(jié)構(gòu)軸向尺寸較小，可用改變彈簧數(shù)量的方法改變彈性力，軸向力較均勻，適用于高速機(jī)械密封，在腐蝕性介質(zhì)中不宜采用。單彈簧機(jī)械密封又稱大彈簧機(jī)械密封，密封結(jié)構(gòu)較為簡(jiǎn)單。有的密封型式還用彈簧傳遞扭矩。國(guó)產(chǎn)密封應(yīng)用大彈簧較多，但不能用于高速。圖五：多彈簧機(jī)械密封圖六：?jiǎn)螐椈蓹C(jī)械密封補(bǔ)償機(jī)構(gòu)的作用是使密封端面緊密貼合，保定RPHRO150-230B凱士比機(jī)械密封，為達(dá)到此目的，采用的方法有兩種，一是彈性力，保定RPHRO150-230B凱士比機(jī)械密封，二是磁力。只有在系統(tǒng)內(nèi)壓力較低時(shí)采用磁力機(jī)械密封（圖7），大多數(shù)都用前者。除了用彈簧形成彈性力外還有用波紋管的，稱為波紋管式機(jī)械密封。波紋管的材料可用橡膠、聚四氟乙烯和焊接的金屬薄片（圖8）等。圖七：磁力機(jī)械密封圖八：波紋管式機(jī)械密封根據(jù)密封面上介質(zhì)載荷的作用情況可分為平衡型和非平衡型密封（圖9）。圖九：平衡型和非平衡型密封非平衡型：載荷系數(shù)k≥1的密封稱為非平衡型密封，保定RPHRO150-230B凱士比機(jī)械密封，換言之，由介質(zhì)壓力變化引起端面比壓的增量大于或等于介質(zhì)壓力的增量。平衡型：載荷系數(shù)K<1的密封。內(nèi)蒙古凱士比機(jī)械密封廠。保定RPHRO150-230B凱士比機(jī)械密封</p><div

則必須更換或修理后再使用。在實(shí)際進(jìn)行安裝時(shí)，不要將超過需要的零件帶到現(xiàn)場(chǎng)，這樣，安裝完畢后零件如有剩余，則是安裝時(shí)有了漏裝的地方；若零件不足，則意味著不必要的地方也組裝上了零件，這也就起到了在安裝時(shí)自檢的作用。（有人認(rèn)為一個(gè)好的裝配工是不需要圖紙和其它標(biāo)記，這是錯(cuò)誤的。那他只是個(gè)熟練工不是個(gè)好檢修工）（2）安裝位置安裝要領(lǐng)隨機(jī)械密封型式、機(jī)器種類的不同而不同。這里不再贅述三、安裝的技術(shù)要求機(jī)械密封是屬于較高精度的機(jī)械部件，對(duì)其正確的安裝與操作對(duì)它的使用壽命有**的影響。我們一般按照石油化工部規(guī)定的標(biāo)準(zhǔn)。安裝機(jī)械密封的泵與機(jī)械密封配合部分的技術(shù)要求如下:1、軸彎曲度：**大不大于；2、轉(zhuǎn)子振擺：動(dòng)環(huán)密封圈處的軸套附近不大于；3、軸的軸向竄動(dòng)量不允許超過±，如果帶軸套，不允許軸套有松動(dòng)；4、聯(lián)軸器的找正誤差：對(duì)于齒式聯(lián)軸器不大于～（P2008C），對(duì)于彈性聯(lián)軸器不大于～；（習(xí)慣做法端跳<）5壓蓋（靜環(huán)座）與密封配合止口對(duì)軸中心線的同心度允差，與墊片接觸的平面對(duì)中心線的垂直度值允差～，如果達(dá)不到要求，密封腔要進(jìn)行加工；6、安裝動(dòng)環(huán)密封圈的軸套端部，以及安裝靜環(huán)密封圈的壓蓋（或殼體）的端部應(yīng)倒角，并修光滑。保定RPHRO150-230B凱士比機(jī)械密封SAFV2/133凱士比機(jī)械密封。</p><div

用以補(bǔ)償軸的振動(dòng)與偏斜，但間隙不能太大，否則會(huì)使動(dòng)環(huán)密封圈卡入而造成機(jī)械密封機(jī)能的破壞。3、機(jī)械密封緊力的校核。我們通常講的機(jī)械密封緊力也就是端面比壓，端面比壓要合適，過大，將使機(jī)械密封摩擦面發(fā)熱，加速端面磨損，增加摩擦功率；過小，容易漏泄。端面比壓是在機(jī)械密封設(shè)計(jì)時(shí)確定的，我們?cè)诮M裝時(shí)只能靠測(cè)量機(jī)械密封緊力來確定。通常情況的測(cè)量方法使測(cè)量安裝好的靜環(huán)端面至壓蓋端面的垂直距離，在測(cè)量動(dòng)環(huán)端面至壓蓋端面的垂直距離，兩者的差極為機(jī)械密封的緊力。4、測(cè)量補(bǔ)償彈簧的長(zhǎng)度是否發(fā)生變化。彈簧性能的發(fā)生變化將會(huì)直接影響機(jī)械密封端面比壓。一般情況下彈簧在長(zhǎng)時(shí)間運(yùn)行后長(zhǎng)度會(huì)縮短，補(bǔ)償彈簧在動(dòng)環(huán)上的機(jī)械密封還會(huì)因?yàn)殡x心力的原因而變形。5、測(cè)量靜環(huán)防轉(zhuǎn)銷子的長(zhǎng)度及銷孔深度，防止銷子過長(zhǎng)靜環(huán)不能組裝到位。這種情況出現(xiàn)會(huì)損壞機(jī)械密封。三．機(jī)械密封的組裝經(jīng)過清掃檢查、技術(shù)尺寸校核后的機(jī)械密封即可回裝，在這個(gè)過程中要注意以下幾點(diǎn)：1、組裝時(shí)所有密封圈因該涂以肥皂水等潤(rùn)滑劑，這樣可以避免組裝過程中損壞膠圈。動(dòng)靜環(huán)的密封面之間涂以潤(rùn)滑脂，防止動(dòng)靜環(huán)密封面在水泵開車前磨損。2、浮動(dòng)環(huán)組裝時(shí)，一定要小心不要碰倒浮動(dòng)環(huán)彈簧。</p><p> 新技術(shù)不斷出現(xiàn)給我們維修帶來了新的課題。(2)結(jié)構(gòu)復(fù)雜、拆裝不便。與其它密封比較，機(jī)械端面密封的零件數(shù)目多，要求精密，結(jié)構(gòu)復(fù)雜。特別是在裝配方面較困難，拆裝時(shí)要從軸端抽出密封環(huán)，必須把機(jī)器部分(聯(lián)軸器)或全部拆卸。這一問題目前已作了某些改進(jìn)，例如采用拆裝方便并可保證裝配質(zhì)量的剖分式和集裝式機(jī)械密封等。機(jī)械密封實(shí)現(xiàn)的原理及結(jié)構(gòu)圖機(jī)械密封原理如圖所示：圖一：機(jī)械密封1、靜環(huán)2、動(dòng)環(huán)3、動(dòng)環(huán)密封面4、推環(huán)5、彈簧6、傳動(dòng)座7、靜環(huán)密封面8、壓蓋9、墊片軸通過傳動(dòng)座（6）和推環(huán)（4），帶動(dòng)動(dòng)環(huán)（2）旋轉(zhuǎn)，靜環(huán)(1)固定不動(dòng)，依靠介質(zhì)壓力和彈簧力使動(dòng)靜環(huán)之間的密封端面緊密貼合，阻止了介質(zhì)的泄漏。摩擦副表面磨損后，在彈簧（5）的推動(dòng)下實(shí)現(xiàn)補(bǔ)償。為了防止介質(zhì)通過動(dòng)環(huán)與軸之間泄漏，裝有動(dòng)環(huán)密封圈（3）；而靜環(huán)密封圈（7）則阻止了介質(zhì)沿靜環(huán)和壓蓋（8）之間的泄漏。按補(bǔ)償機(jī)構(gòu)彈性元件的運(yùn)動(dòng)狀況，可分為旋轉(zhuǎn)式和靜止式機(jī)械密封。補(bǔ)償機(jī)構(gòu)隨軸旋轉(zhuǎn)的稱為旋轉(zhuǎn)式機(jī)械密封（圖2）；補(bǔ)償機(jī)構(gòu)不旋轉(zhuǎn)的（安裝在壓蓋內(nèi)）稱為靜止式機(jī)械密封（圖3）。補(bǔ)償機(jī)構(gòu)旋轉(zhuǎn)時(shí)易產(chǎn)生質(zhì)量不平衡，同時(shí)消耗攪拌功率，因此，旋轉(zhuǎn)式密封不能用于高速。凱士比機(jī)械密封MCPK6540-160。</p><div

重點(diǎn)檢查：1、動(dòng)靜環(huán)表面是否存在劃痕、裂紋等缺陷，這些缺陷存在會(huì)造成機(jī)械密封嚴(yán)重漏泄。有條件的可以用專用工具檢查密封面是否平整，密封面不平整，壓力水會(huì)進(jìn)入組裝后機(jī)械密封的動(dòng)靜環(huán)密封面，將動(dòng)靜環(huán)分開，機(jī)械密封失效。必要時(shí)可以制作工裝在組裝前水壓試驗(yàn)。2、檢查動(dòng)靜環(huán)座是否存在影響密封的缺陷。如動(dòng)靜環(huán)座與動(dòng)靜環(huán)密封膠圈配合表面是否存在傷痕等缺陷。3、檢查機(jī)械密封補(bǔ)償彈簧是否損壞及變形，倔強(qiáng)系數(shù)是否變化。4、檢查密封軸套是否存在毛刺、溝痕等缺陷。5、清掃檢查所有密封膠圈是否存在裂紋、氣孔等缺陷，測(cè)量膠圈直徑是否在工差范圍內(nèi)。6、具有泵送機(jī)構(gòu)的機(jī)械密封還要檢查螺旋泵的螺旋線是否存在裂紋、斷線等缺陷。二．機(jī)械密封組裝技術(shù)尺寸校核機(jī)械密封檢修工藝較為復(fù)雜，要保證組裝后的機(jī)械密封無漏泄，機(jī)械密封技術(shù)尺寸的校核必不可少。1、測(cè)量動(dòng)環(huán)、靜環(huán)密封面的尺寸。這項(xiàng)數(shù)據(jù)是用來驗(yàn)證動(dòng)靜環(huán)的徑向?qū)挾?，?dāng)選用不同的摩擦材料時(shí)，硬材料摩擦面徑向?qū)挾葢?yīng)比軟的大1－3mm，否則易造成硬材料端面的棱角嵌入軟材料的端面上去。2、檢查動(dòng)環(huán)、靜環(huán)與軸或軸套的間隙，靜環(huán)的內(nèi)徑一般比軸徑大1－2mm，對(duì)于動(dòng)環(huán)，為保證浮動(dòng)性，內(nèi)徑比軸徑大－1mm。凱士比機(jī)械密封RPK100-400。保定RPHRO150-230B凱士比機(jī)械密封</p><p
