在機(jī)械密封水泵的常見故障中，機(jī)械密封的故障大約占整個(gè)維修工作量的一半。可見機(jī)械密封在機(jī)泵維修中所占的位置。由于機(jī)泵所輸送的介質(zhì)千差萬別，工藝條件各不相同，所以了解這些情況對(duì)機(jī)封的選擇及維護(hù)很重要。結(jié)合多年來在機(jī)封選擇和維修中的經(jīng)驗(yàn)，介紹幾種特殊工況下機(jī)械密封的工作特點(diǎn)和注意事項(xiàng)。一、高溫下的機(jī)械密封一般情況下，介質(zhì)的溫度超過120℃即認(rèn)為是高溫密封。此時(shí)機(jī)械密封存在的主要問題有：(1)由于摩擦副端面溫度升高，導(dǎo)致密封端面間液膜氣化，摩擦系數(shù)隨之增大，磨損加劇，溫升加大，密封環(huán)產(chǎn)生熱變形或熱裂而失效；(2)機(jī)械密封中的輔助密封圈材料一般為橡膠或聚四氟乙烯，由于長(zhǎng)時(shí)間在高溫環(huán)境中，容易老化和分解，造成密封失效；(3)高溫下機(jī)械密封的彈性元件易產(chǎn)生疲勞和蠕變，使密封失效；(4)高溫會(huì)加劇金屬材料的腐蝕，縮短機(jī)封的使用壽命。為保證機(jī)械密封在高溫環(huán)境下正常工作，可以采取如下措施：1、給機(jī)封增加冷卻沖洗裝置。2、選擇耐高溫的材料，根據(jù)不同的工作溫度選用不同的材料。丁腈橡膠溫度上限為80℃，硅橡膠和氟橡膠為200℃，聚四氟乙烯為250℃。另外，機(jī)械密封中的非金屬摩擦副多采用石墨浸漬材料制成。</p><p> 人們?cè)诜治鰴C(jī)械封泄漏原因時(shí)，習(xí)慣在機(jī)械封自身方面查找原因，比如：它的選型是否合適，材料選擇是否正確，密封面的比壓是否正確。摩擦副的選擇是否合理，端蓋與軸是否垂直等等，而很少在機(jī)械密封的外部條件方面去查找原因，其實(shí)機(jī)械密封的外因也挺重要的，比如：泵給機(jī)械密封創(chuàng)造的條件是否合適，輔助系統(tǒng)的配置是否合適等。一、機(jī)械密封的原理及要求機(jī)械密封系指兩塊密封元件在其垂直于軸線的光潔而平直的表面上相互貼合，并作相對(duì)轉(zhuǎn)動(dòng)而構(gòu)成的密封裝置，他通常由靜環(huán)、動(dòng)環(huán)、彈簧加荷裝置（包括推環(huán)，彈簧盒）輔助密封圈（動(dòng)環(huán)密封圈、靜環(huán)密封圈）等元件組成，防轉(zhuǎn)套里面的防轉(zhuǎn)銷固定在外壓蓋上，以防止靜環(huán)轉(zhuǎn)動(dòng)。其中動(dòng)環(huán)和靜環(huán)的端面組成一對(duì)摩擦副，動(dòng)環(huán)靠密封室內(nèi)液體的壓力使其端面壓緊在靜環(huán)端面上，并在兩環(huán)端面上產(chǎn)生適當(dāng)?shù)谋葔汉捅３忠粚訕O薄的液體膜而達(dá)到密封的，因此從結(jié)構(gòu)來看，機(jī)械密封主要是將其極易泄漏的軸向密封，改變?yōu)椴灰仔孤┑亩嗣婷芊?，機(jī)械密封在實(shí)際運(yùn)行過程中，不是一個(gè)單獨(dú)的部件，它是與其他的零部件一起組合起來運(yùn)行的同時(shí)通過其基本原理可以看出，機(jī)械密封的正常運(yùn)行必須具備以下條件：（1）泵軸的竄量不能太大；。襄樊五二五機(jī)械密封LC500/630。</p><div

2）機(jī)械密封處的泵軸撓度要小，只有滿足類似這樣的外因，再加上良好的機(jī)械密封自身性能，才能達(dá)到理想的密封效果。二、影響泵用機(jī)械密封的外部原因（一）泵軸的軸向竄量機(jī)械密封的密封面要有一定的比壓（～），從而達(dá)到密封的目的，兩端面的緊密緊密程度可以通過彈簧調(diào)節(jié)。為了保證這個(gè)比壓，要求泵軸不能有太大的竄量（≤），但在實(shí)際生產(chǎn)中，往往泵軸產(chǎn)生很大的竄量。對(duì)機(jī)械密封的使用非常不利的，這種情況在我分廠表現(xiàn)在泵啟動(dòng)過程中，由于不平衡軸向力的存在，使整個(gè)軸發(fā)生向吸入口的竄動(dòng)，造成機(jī)械密封失去密封作用，常用的措施有：葉輪上開平衡孔，泵體上裝平衡管等。（二）泵軸的撓度偏大軸彎曲變形時(shí)橫截面形心沿與軸線垂直方向的線位移稱為撓度，機(jī)械密封要求兩個(gè)密封端面之間受力均勻。但由于泵產(chǎn)品設(shè)計(jì)的不合理，在機(jī)械密封安裝處產(chǎn)生的撓度偏大，使密封處受力不均勻，從而失去密封效果。這種現(xiàn)象大多存在臥式多級(jí)離心泵中。（三）沒有輔助沖洗系統(tǒng)或輔助沖洗系統(tǒng)設(shè)計(jì)不合理機(jī)械密封的輔助沖洗系統(tǒng)是非常重要的，它可以有效的保護(hù)密封面，起到冷卻、潤(rùn)滑、沖走雜物等作用。有時(shí)設(shè)計(jì)人員設(shè)計(jì)不合理，達(dá)不到密封效果；有的設(shè)計(jì)了輔助系統(tǒng)，但由于沖洗液中有雜質(zhì)。LCF40/250襄樊五二五機(jī)械密封。南昌ZTM-40S351襄樊五二五機(jī)械密封</p><p
