圖29）旋轉(zhuǎn)式機械密封軸套和傳動座傳動方式：l）頂絲傳動（圖30）。傳動座用1～2個頂絲固定在軸套表面上，結(jié)構(gòu)簡單，但是安裝時軸套需從軸上取出，方能緊固頂絲。這種結(jié)構(gòu)要求在軸套表面（與頂絲接觸的部位）劃一凹坑，否則運轉(zhuǎn)中易出現(xiàn)傳動失效，傳動座會發(fā)生軸向串動。在直徑較大和溫度較高時，不能采用單純的頂絲傳動。2）頂絲一臺階傳動（圖31），蕪湖雙端面泵用機械密封。為了克服單純頂絲傳動時，傳動座軸向串動，可在軸套上設(shè)一臺階，傳動座頂靠在幼查臺階端面，體傳動成無法串動定位，用鍵來帶動軸套旋轉(zhuǎn)。這種結(jié)構(gòu)簡單，安裝方便，現(xiàn)場施工時可不用拆卸軸套即可安裝傳動座，使用可靠，運動中不會產(chǎn)生傳動失效。3）鍵傳動。4）撥叉?zhèn)鲃樱▓D33）。是鍵傳動基礎(chǔ)上改進的，軸套上仍有臺階，傳動座為沖壓件，上面有兩個小“爪”（撥叉）伸到軸套臺階的槽中實現(xiàn)傳動，結(jié)構(gòu)也很簡單，蕪湖雙端面泵用機械密封。由于是沖壓件，撥叉徑向尺寸?。ㄝ^?。?，沖壓后冷作硬化，撥叉易斷裂。在中性介質(zhì)中尚可使甩。5)彈簧傳動。這種傳動方式不用傳動座，蕪湖雙端面泵用機械密封，傳動彈簧依靠過盈值旋緊在軸套上，并傳遞扭矩，彈簧的端部靠緊軸套的臺階處（圖34），防止軸向位移。這種方式結(jié)構(gòu)簡單，安裝方便，但對彈簧的旋向有要求，泵軸旋轉(zhuǎn)時。貴陽飛力泵用機械密封廠家。蕪湖雙端面泵用機械密封</p><div

由于填充物被密封介質(zhì)腐蝕而產(chǎn)生泄漏的現(xiàn)象在化工行業(yè)的用泵中也時有發(fā)生，因此對填充物的選擇也是密封考慮的因素之一。螺旋密封螺旋密封也是動力密封的一種形式，它是在旋轉(zhuǎn)的軸上或者在軸的包容套上加工出螺旋槽，軸和套之間充有密封介質(zhì)。軸的旋轉(zhuǎn)使螺旋槽產(chǎn)生類似于泵的輸送作用，從而阻止密封液的泄漏。其密封能力的大小與螺旋角度、螺距、齒寬、齒高、齒的作用長度以及軸與套之間的間隙大小有關(guān)。由于密封之間不發(fā)生磨擦，因而壽命長，但由于結(jié)構(gòu)空間的限制，其螺旋長度一般較短，因而其密封能力也受到局限。在泵降速使用時，其密封效果則會大打折扣。迷宮密封在設(shè)計合理，加工精良，裝配完好、轉(zhuǎn)速較高時，迷宮密封效果很好。但在實際應(yīng)用中，因此而產(chǎn)生的泄漏卻很多，分析其原因主要有：1、密封副(如軸和軸承壓蓋)配合間隙太大，而此間隙與密封效果成反比。配合面粗糙，明顯的螺旋狀車刀痕在有些情況下也加大了泄漏趨勢。2、軸承室內(nèi)潤滑油注入量太多，其溢出壓力超過了密封阻力。3、油窗或油位計安裝位置有誤，誤導(dǎo)了人們對油室內(nèi)潤滑油量的正確判斷。4、運轉(zhuǎn)中油溫的升高使其粘度降低，增加了泄漏的可能。5、回油槽或回油孔尺寸偏小，或受到其它障礙。</p><p> 而用于高速泵的機械密封尺寸一般都在2in左右.高速泵用的機械密封以美國約翰克蘭公司(JohnCranePackingCompany)的9AB型密封**為典型[圖10-17(a),(b)]，這種密封常用在美國Sundstrand公司高速泵的齒輪箱和泵體的密封上.為了節(jié)省空間并獲得較高的重量與功率比，無論泵的結(jié)構(gòu)和機械密封結(jié)構(gòu)都很緊湊，一般石油化工公司都引進這種高速泵‘，目前揚子石油化工公司有關(guān)裝置使用51臺(見表3-41)，中國石油化工總公司系統(tǒng)使用近200臺。圖中60C用于齒輪箱密封，60A或60A+60B用于泵葉輪端密封.低溫機械密封一般低溫機械密封是指工作溫度在0~-50℃的密封，API-610的低溫含義指溫度低于-29℃，國內(nèi)通常以密封腔溫度低于-20℃為低溫.實際上，低溫范圍較寬，可以劃分為:低溫:-20~-50℃中低溫:-50~-100℃極低溫:-100~-196℃**溫:<-196℃泵送低溫介質(zhì)主要指液化氣體和易揮發(fā)的液體，如液態(tài)氮、液態(tài)氧、甲烷、乙烷、乙烯等液化氣。關(guān)于氮、氧、空氣等液化氣體的物理性能如表10-3所示.關(guān)于乙烯、丙烯、甲烷、乙烷、丙烷的物理性能如圖10-18(a)、(b)、(c)、(d)所示·一、低溫機械密封的要求1.材料要求金屬材料隨著溫度降低。天津飛力泵用機械密封型號。</p><div

法蘭的粗糙度以及螺栓信息等來選擇合適的墊片材質(zhì)和型式。非金屬類法蘭就必須選擇預(yù)緊力要求比較小的墊片，否則很可能會有在法蘭上緊過程中，墊片還沒有壓緊而法蘭已經(jīng)壓碎的情況出現(xiàn)（如圖4）。圖4非金屬法蘭被壓碎對于不同的法蘭密封面型式，與之相對應(yīng)的墊片型式也是不一樣的，例如突面法蘭（RF）對應(yīng)的纏繞墊片型式就是帶內(nèi)外環(huán)型纏繞墊片，榫槽面（TG）法蘭對應(yīng)的纏繞墊片型式就是基本型纏繞墊片，凹凸面（MFM）法蘭對應(yīng)的纏繞墊片型式就是只帶內(nèi)環(huán)的纏繞墊片（如圖5）。圖5不同的法蘭密封面型式對應(yīng)不同型式的纏繞墊片不同的墊片對于法蘭粗糙度要求也是不一樣的，具體可以參考圖6。圖6不同墊片推薦的法蘭表面粗糙度介質(zhì)墊片應(yīng)在全程工作條件下不受密封介質(zhì)的影響，包括抗高溫氧化性、抗化學(xué)腐蝕性、抗溶劑性、抗?jié)B透性等，顯然墊片材料對介質(zhì)的耐化學(xué)腐蝕性是選擇墊片的首要條件。對于非金屬墊片或者復(fù)合墊片中的非金屬材料來說，材料的耐化學(xué)腐蝕性能可以參考墊片廠家提供的非金屬材料抗化學(xué)品性能表。對于墊片中跟介質(zhì)直接接觸的金屬材料，應(yīng)和法蘭材料一樣或有更高的耐腐蝕性能。壓力墊片必須能夠承受壓力，這種壓力或許是試驗壓力，它可能是正常工作壓力的。江西飛力泵用機械密封型號。北京耐腐蝕泵用機械密封</p><p
