氣體阻塞密封系統(tǒng)過去阻塞密封系統(tǒng)中常用液體阻塞液體或液體阻塞氣體現(xiàn)在為了簡化龐大的阻塞液體系統(tǒng)，改用阻塞氣體來阻塞液體或氣體阻塞密封系統(tǒng)中可采用螺旋槽氣體密封與阻塞氣體，浮動(dòng)套與阻塞氣體等來阻塞氣體和液體。密封環(huán)是動(dòng)環(huán)和靜環(huán)的總稱(下同)，是構(gòu)成機(jī)械密封主要的元件。密封環(huán)在很大程度上決定了機(jī)械密封的使用性能和壽命，因此，對(duì)它提出了一些要求。有足夠的強(qiáng)度和剛度在工作條件下(如壓力、溫度和滑動(dòng)速度等)不損壞，變形應(yīng)盡量的小，工作條件波動(dòng)時(shí)仍能保持密封性。尤其是密封端面要有足夠的強(qiáng)度以及一定的耐腐蝕能力，以保證產(chǎn)品有滿意的使用壽命。有良好的耐熱沖擊能力為此，要求材料有較高的導(dǎo)熱系數(shù)和較小的線膨脹系數(shù)，承受熱沖擊時(shí)不至于開裂。較小的摩擦系數(shù)密封環(huán)匹配應(yīng)有較小的摩擦系數(shù)。良好的自潤滑性工作中如發(fā)生短時(shí)間的干摩擦，不損傷密封端面。因此，密封環(huán)要有良好的自潤滑性，密封環(huán)材料與密封流體還要有很好的浸潤性。結(jié)構(gòu)簡單密封環(huán)結(jié)構(gòu)應(yīng)力求簡單對(duì)稱，優(yōu)先考慮用整體型結(jié)構(gòu)，也可采用組合式(如鑲裝式)密封環(huán)，盡量避免用密封端面噴涂式結(jié)構(gòu)。密封環(huán)要容易加工制造安裝和維修要方便，價(jià)格要低廉。</p><p> 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滿足加載彈力?！皺C(jī)械密封”通常被人們簡稱為“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。凱泉泵用機(jī)械密封KQH65-315B。</p><div

機(jī)械密封的作用一、提高機(jī)器效率、降低能耗。1、減少機(jī)器的內(nèi)漏、外漏和穿漏，提高機(jī)器容積效率。例如，大慶煉油廠將焦化5FDJ5×2離心泵的葉輪口環(huán)改為機(jī)械密封，使泵效率提高。2、減少摩擦損失，提高機(jī)器的機(jī)械效率。例如，將雙端面密封改為單端面密封、非平衡型改為平衡型、雙支承減底泵封閉一端(所謂砍頭泵)減少密封都能減少摩擦損失，提高機(jī)械效率。3、改變密封方式，提高機(jī)器或機(jī)組的效率。例如，將屏蔽泵改用機(jī)械密封泵，使電動(dòng)機(jī)效率提高;采用磁力傳動(dòng)泵，提高機(jī)器效率。4、改變輔助系統(tǒng)，減少能耗，提高機(jī)組效率。例如，熱油泵自沖洗改為小葉輪循環(huán)沖洗;雙端面密封改為單端面密封，節(jié)省封油輔助系統(tǒng)的能耗。二、節(jié)約原材料。例如，工藝流體回收，減少或消除動(dòng)力蒸汽和工藝流體的損耗，減少封油損耗等。三、提高機(jī)器可靠性。例如，軸封的漏損和壽命決定軸封和機(jī)器的可靠性。四、安全和環(huán)境保護(hù)。根據(jù)日本某廠調(diào)查報(bào)告，在發(fā)生的786件事故中有32件是泄漏造成的(占42%)。此外工藝流體泄漏還會(huì)造成環(huán)境污染，包括對(duì)大氣污染、水污染和車間環(huán)境污染。機(jī)械密封的安裝（1）熟悉設(shè)備情況。安裝機(jī)械密封之前，對(duì)轉(zhuǎn)軸的轉(zhuǎn)速、軸徑等都要進(jìn)行熟悉。青島KQDQ100-90凱泉泵用機(jī)械密封</p></p><br
