泵類的機(jī)械密封件使用要注意以下事項(xiàng)：很多人都會(huì)認(rèn)為機(jī)械密封件拆開來(lái)修要比不拆開好，遇到密封件產(chǎn)生滲漏的時(shí)候，就急急忙忙地拆開來(lái)維修，很多的時(shí)候密封件并沒(méi)有損壞，只是稍稍調(diào)整了密封件就可以解決滲漏的問(wèn)題，避免不必要的浪費(fèi)。機(jī)械密封件的靜環(huán)密封圈也不可以上得太緊，雖然其處于靜止的狀態(tài)，但是過(guò)緊也會(huì)引起其過(guò)度的形變，密封效果不佳，有些靜環(huán)密封圈使用的是石墨的材質(zhì)，比較脆過(guò)度用力上緊，容易產(chǎn)生碎裂，在安裝和拆卸的過(guò)程中也是極其容易損壞，建議使用一些進(jìn)口密封件使用壽命會(huì)更長(zhǎng)些。機(jī)械密封件中的動(dòng)環(huán)密封圈松緊要適中，若是動(dòng)環(huán)密封圈上得過(guò)緊使得摩擦力增加，加快了動(dòng)環(huán)密封圈和軸套之間的磨損使得過(guò)早地產(chǎn)生滲漏。增大動(dòng)環(huán)軸向的調(diào)整將和移動(dòng)時(shí)的阻力。在經(jīng)常變化的工況的情況下，沒(méi)有辦法進(jìn)行適當(dāng)?shù)恼{(diào)整。彈簧也會(huì)過(guò)緊產(chǎn)生疲勞失效嚴(yán)重的甚至損壞，也容易使得動(dòng)環(huán)密封圈產(chǎn)生嚴(yán)重變形，密封效果不好。機(jī)械密封件中的彈簧壓縮時(shí)候幅度要適中，切不可以認(rèn)為彈簧壓縮幅度越大，密封的效果也就越好，其實(shí)不是這樣的，彈簧被壓縮的過(guò)大了，摩擦也就大幅增加，密封件也就會(huì)磨損加劇嚴(yán)重甚至燒壞，過(guò)分的壓縮彈簧，也就容易失去動(dòng)環(huán)端面的調(diào)節(jié)能力。哈爾濱凱泉泵用機(jī)械密封DG155-67MD85-45凱泉泵用機(jī)械密封。</p><div

機(jī)械密封件有什么常識(shí)，選型的基本原則為：1、根據(jù)密封腔體壓力，確定密封結(jié)構(gòu)采用平衡型或非平衡型，單端面或雙端面等。2、根據(jù)工作速度，確定采用旋轉(zhuǎn)式或靜止式，流體動(dòng)壓式或非接觸型。3、根據(jù)溫度及流體性質(zhì)，確定摩擦副和輔助密封材料，以及正確選擇潤(rùn)滑、沖洗、保溫、冷卻等機(jī)械密封循環(huán)保護(hù)系統(tǒng)等。4、根據(jù)安裝密封的有效空間，確定采用多彈簧或單彈簧或波形彈簧，內(nèi)裝式或外裝式。機(jī)械密封(mechanicalseal)是指由至少一對(duì)垂直于旋轉(zhuǎn)軸線的端面在流體壓力和補(bǔ)償機(jī)構(gòu)彈力（或磁力）的作用下以及輔助密封的配合下保持貼合并相對(duì)滑動(dòng)而構(gòu)成的防止流體泄漏的裝置。彈力加載機(jī)構(gòu)與輔助密封是金屬性紋管的機(jī)械密封我們稱為金屬波紋管密封。在輕型密封中，還有使用橡膠波紋管作輔助密封的，橡膠波紋管彈力有限，一般需要輔以彈簧來(lái)滿足加載彈力。“機(jī)械密封”通常被人們簡(jiǎn)稱為“機(jī)封”。機(jī)械密封是一種旋轉(zhuǎn)機(jī)械的軸封裝置。比如離心泵、離心機(jī)、反應(yīng)釜和壓縮機(jī)等設(shè)備。由于傳動(dòng)軸貫穿在設(shè)備內(nèi)外，這樣，軸與設(shè)備之間存在一個(gè)圓周間隙，設(shè)備中的介質(zhì)通過(guò)該間隙向外泄漏，如果設(shè)備內(nèi)壓力低于大氣壓，則空氣向設(shè)備內(nèi)泄漏，因此必須有一個(gè)阻止泄漏的軸封裝置。軸封的種類很多。</p><p> 檢漏時(shí)亦可采用壓降法或靜態(tài)升壓法。為縮短試驗(yàn)時(shí)間，各段檢漏可同時(shí)進(jìn)行。必要時(shí)應(yīng)采用其他檢測(cè)儀器和方法進(jìn)行檢漏，以確定每段的泄漏狀況，找出泄漏點(diǎn)。對(duì)于需進(jìn)行烘烤或冷卻的部件，必須經(jīng)冷、熱沖擊試驗(yàn)后再進(jìn)行檢漏。例如冷阱、冷卻障板等部件，在烘烤除氣后，應(yīng)立即注入冷卻劑（液氮、氟里昂等），然后測(cè)量其泄漏率。值得注意的是，在這些過(guò)程中，泄漏不一定是在冷態(tài)或熱態(tài)出現(xiàn)。7、如果檢測(cè)出泄漏，又確定了泄漏點(diǎn)，就應(yīng)立即進(jìn)行修補(bǔ)或更換。修補(bǔ)或更換后的部件或設(shè)備應(yīng)重新進(jìn)行檢漏，直至合格為止。表7-4列出了部分泄漏原因和應(yīng)采取的措施。運(yùn)行維修階段如果在以前各階段中，作了徹底檢漏并進(jìn)行了修補(bǔ)，通常短時(shí)間內(nèi)不會(huì)出現(xiàn)泄漏。正式運(yùn)轉(zhuǎn)階段中，如果經(jīng)常出現(xiàn)泄漏，就應(yīng)根據(jù)產(chǎn)生泄漏的不同性質(zhì)，重新進(jìn)行計(jì)劃、設(shè)計(jì)和加工階段的審查。運(yùn)行維修階段主要應(yīng)做好以下幾項(xiàng)工作。1、運(yùn)轉(zhuǎn)日記為了能對(duì)事先制定的維修計(jì)劃不斷進(jìn)行修正，使之趨于完善，應(yīng)該詳細(xì)記錄設(shè)備每天的運(yùn)轉(zhuǎn)狀況。設(shè)備的運(yùn)轉(zhuǎn)日記里同時(shí)應(yīng)記錄泄漏方面的情況。不僅要記錄系統(tǒng)壓力、溫度、流量等的變化，而且應(yīng)把與泄漏有關(guān)的情況都記錄下來(lái)。由于泄漏與工況、介質(zhì)，設(shè)備的結(jié)構(gòu)、材料等諸多因素有關(guān)。凱泉泵用機(jī)械密封KQH65-315B。</p><div

會(huì)導(dǎo)致環(huán)表面出現(xiàn)徑向裂紋，從而使動(dòng)靜環(huán)急劇磨損，密封面泄漏迅速增加。碳化鎢環(huán)熱裂現(xiàn)象較常見(jiàn)。2.發(fā)泡、炭化使用中如石墨環(huán)超過(guò)允許使用溫度，則其表面會(huì)析出樹脂，摩擦面附近樹脂會(huì)發(fā)生炭化，當(dāng)有黏結(jié)劑時(shí)，又會(huì)發(fā)泡軟化，使密封面泄漏量增加，密封失效。3.老化、龜裂、溶脹橡膠超過(guò)許用溫度繼續(xù)使用，將迅速老化、龜裂、變硬失彈。如是有機(jī)介質(zhì)則溶脹失彈，這些均會(huì)導(dǎo)致密封失效。凡因熱損引起的密封失效，關(guān)鍵在于盡量降低摩擦熱，改善散熱，使密封面處不發(fā)生溫度劇變。磨損失效摩擦副若用材耐磨性差、摩擦因數(shù)大、端面比壓（包括彈簧比壓）過(guò)大、密封面進(jìn)入固體顆粒等均會(huì)使密封面磨損過(guò)快而引起密封失效。采用平衡型機(jī)械密封以減少端面比壓及安裝中適當(dāng)減少?gòu)椈蓧毫?，有利于克服因磨損引起的失效，此外，選用良好的摩擦副材料可以減輕磨損。按耐磨次序材料排列為碳化鎢-碳石墨、硬質(zhì)合金-碳石墨、陶瓷（氧化鋁）-碳石墨、噴涂陶瓷-碳石墨、氧化硅陶瓷-碳石墨、高速鋼-碳石墨、堆焊硬質(zhì)合金-碳石墨。KQDP50-16S凱泉泵用機(jī)械密封。哈爾濱凱泉泵用機(jī)械密封DG155-67</p><p

所以有時(shí)很難檢查出泄漏的原因，如果有詳細(xì)的記錄，就便于依據(jù)記錄作出正確的判斷，并采取相應(yīng)的預(yù)防措施。此外，對(duì)維修檢查內(nèi)容也應(yīng)作詳細(xì)記錄。2、維修、檢查在設(shè)備運(yùn)行維修工作中應(yīng)高度重視泄漏問(wèn)題，并采取相應(yīng)的措施。例如，積極地進(jìn)行檢漏試驗(yàn)，也屬于維修工作的一部分。對(duì)加壓裝置，可采用檢漏器每天巡回檢測(cè)一次；對(duì)真空裝置，可暫時(shí)關(guān)閉排氣系統(tǒng)的閥門，采用靜態(tài)升壓法作短時(shí)間的檢漏試驗(yàn)。某些部件更換后，如出現(xiàn)泄漏故障，與更換前的狀況比較后往往可以判斷出具體的泄漏點(diǎn)。若能每天堅(jiān)持記錄設(shè)備的運(yùn)轉(zhuǎn)情況，則除了突發(fā)性泄漏外，一般可以預(yù)測(cè)系統(tǒng)何時(shí)將出現(xiàn)超過(guò)允許泄漏率的泄漏問(wèn)題。實(shí)際使用過(guò)程中應(yīng)逐步修改維修計(jì)劃以使之更符合實(shí)際情況。3、定期檢修定期檢修對(duì)防止泄漏十分重要。平時(shí)發(fā)生泄漏，設(shè)備不能停止運(yùn)轉(zhuǎn)，只能采取臨時(shí)性措施。定期檢修時(shí)，由于設(shè)備停止運(yùn)轉(zhuǎn)，因而可以做徹底的修補(bǔ)，也可以更換新的部件，對(duì)更換的部件要進(jìn)行檢漏。另外，定期檢修可以進(jìn)一步查明泄漏原因，找出防止泄漏事故發(fā)生的方法。哈爾濱凱泉泵用機(jī)械密封DG155-67</p></p><br
