泵用機(jī)械密封種類繁多，型號(hào)各異，但泄漏點(diǎn)主要有五處：1）軸套與軸間的密封；2）動(dòng)環(huán)與軸套間的密封；3）動(dòng)、靜環(huán)間密封；4）對(duì)靜環(huán)與靜環(huán)座間的密封；5）密封端蓋與泵體間的密封。1.安裝靜試時(shí)泄漏機(jī)械密封安裝調(diào)試好后，一般要進(jìn)行靜試，觀察泄漏量。如泄漏量較小，多為動(dòng)環(huán)或靜環(huán)密封圈存在問題；泄漏量較大時(shí)，則表明動(dòng)、靜環(huán)摩擦副間存在問題。在初步觀察泄漏量、判斷泄漏部位的基礎(chǔ)上，再手動(dòng)盤車觀察，若泄漏量無明顯變化則靜、動(dòng)環(huán)密封圈有問題；如盤車時(shí)泄漏量有明顯變化則可斷定是動(dòng)、靜環(huán)摩擦副存在問題；如泄漏介質(zhì)沿軸向噴射，則動(dòng)環(huán)密封圈存在問題居多，泄漏介質(zhì)向四周噴射或從水冷卻孔中漏出，則多為靜環(huán)密封圈失效。此外，泄漏通道也可同時(shí)存在，但一般有主次區(qū)別，只要觀察細(xì)致，熟悉結(jié)構(gòu)，一定能正確判斷。2.試運(yùn)轉(zhuǎn)時(shí)出現(xiàn)的泄漏泵用機(jī)械密封經(jīng)過靜試后，運(yùn)轉(zhuǎn)時(shí)高速旋轉(zhuǎn)產(chǎn)生的離心力，會(huì)壓制介質(zhì)的泄漏。因此，試運(yùn)轉(zhuǎn)時(shí)機(jī)械密封泄漏在排除軸間及端蓋密封失效后，基本上都是由于動(dòng)、靜環(huán)摩擦副受破壞所致。引起摩擦副密封失效的因素主要有：（l）操作中，因抽空、氣蝕、憋壓等異?，F(xiàn)象，引起較大的軸向力，使動(dòng)、靜環(huán)接觸面分離；。</p><p> 沖洗的方式主要有如下：（一）內(nèi)沖洗1、正沖洗1）特點(diǎn)：利用工作主機(jī)的被密封介質(zhì)，由泵的出口端通過管路引入密封腔。2）應(yīng)用：用于清潔流體，p1稍大于p進(jìn)，當(dāng)溫度高或有雜質(zhì)時(shí)，可在管路上設(shè)置冷卻器、過濾器等。2、反沖洗1）特點(diǎn)：利用工作主機(jī)的被密封介質(zhì)，由泵的出口端引入密封腔，沖洗后通過管路流回泵入口。2）應(yīng)用：用于清潔流體，且p進(jìn)3、全沖洗1）特點(diǎn)：利用工作主機(jī)的被密封介質(zhì)，由泵的出口端通過管路引入密封腔，沖洗后再經(jīng)管路流回泵入口。（二）外沖洗特點(diǎn)：引入外系統(tǒng)與被密封介質(zhì)相容的清潔流體至密封腔進(jìn)行沖洗。應(yīng)用：外沖洗液壓力應(yīng)比被密封介質(zhì)大，適用于介質(zhì)為高溫或固體顆粒的場(chǎng)合。沖洗液的流量應(yīng)保證帶走熱量，還需滿足沖洗的需要，不會(huì)產(chǎn)生對(duì)密封件的沖蝕。為此，需控制密封腔的壓力和沖洗的流速，一般清潔沖洗液的流速應(yīng)小于5m/s；含有顆粒的漿狀液體須小于3m/s，為達(dá)到上述的流速值，沖洗液與密封腔壓力的差值應(yīng)<，一般取，對(duì)雙端面機(jī)械密封可取，沖洗液進(jìn)入和排出密封腔的孔口位置，應(yīng)設(shè)置在密封端面附近，且應(yīng)在靠近動(dòng)環(huán)側(cè)，為了防止石墨環(huán)被沖蝕或因冷卻不均引起溫差變形，以及雜質(zhì)堆積和結(jié)焦等，可采用切向引入或多點(diǎn)沖洗.必要時(shí)。無錫109-25機(jī)械密封件。</p><div

機(jī)械密封概述泄露是機(jī)械設(shè)備常產(chǎn)生的故障之一。造成泄露的原因主要有兩方面：由于機(jī)械加工的結(jié)果，機(jī)械產(chǎn)品的表面必然存在各種缺陷和形狀及尺寸偏差，因此，在機(jī)械零件聯(lián)接處不可避免地會(huì)產(chǎn)生間隙；密封兩側(cè)存在壓力差，工作介質(zhì)就會(huì)通過間隙而泄露。密封的作用就是將接合面間的間隙封住，隔離或切斷泄露通道，增加泄露通道中的阻力，或者在通道中加設(shè)小型做功元件，對(duì)泄露物造成壓力，與引起泄露的壓差部分抵消或完全平衡，以阻止泄露。機(jī)械密封的形式機(jī)械密封通常是由密封圈來實(shí)現(xiàn)的，以O(shè)型密封圈為例：密封部位結(jié)構(gòu)簡(jiǎn)單，安裝部位緊湊，重量較輕；有自密封作用，往往只用一個(gè)密封件便能完成密封，不需要周期性調(diào)整;密封性能較好，用作靜密封時(shí)幾乎可以做到?jīng)]有泄露；運(yùn)動(dòng)摩擦阻力很小，對(duì)于壓力交變的場(chǎng)合也能適應(yīng)；尺寸和溝槽已標(biāo)準(zhǔn)化，成本低，便于使用。68頁(yè)內(nèi)容介紹機(jī)械密封知識(shí)（文末有獲?。?000G機(jī)械領(lǐng)域相關(guān)設(shè)計(jì)資料內(nèi)容詳情1000G機(jī)械相關(guān)領(lǐng)域資料內(nèi)容涉及的面很廣，具體來說內(nèi)容涵蓋傳統(tǒng)機(jī)械行業(yè)、機(jī)械加工、制造技術(shù)、材料類、材料成型、電氣行業(yè)、液壓行業(yè)、機(jī)電類、機(jī)械傳動(dòng)、一千多份非標(biāo)設(shè)備三維模型和非標(biāo)設(shè)計(jì)等等領(lǐng)域。江陰109-20機(jī)械密封件。濰坊單機(jī)械密封</p><p

沖洗液可以是熱水或蒸汽。九、機(jī)械密封典型失效原因分析（一）機(jī)械密封本身問題1、鑲裝不到位或不平整。2、載荷系數(shù)太大或端面比壓設(shè)計(jì)不合理。3、材質(zhì)選用不當(dāng)。4、密封面不平。5、密封面太寬或太窄。（二）輔助系統(tǒng)問題1、工況條件復(fù)雜，但沒有沖洗等輔助設(shè)施。2、沖洗管堵塞。3、冷卻管結(jié)垢。（三）介質(zhì)及工作條件問題1、介質(zhì)腐蝕性強(qiáng)。2、介質(zhì)中有固體顆粒。3、設(shè)備抽空。4、密封面結(jié)晶。5、介質(zhì)粘度太大。（四）泵的問題1、軸的加工精度不佳、串軸、跳動(dòng)、安裝間隙過大。2、泵開啟后振動(dòng)太大。3、壓蓋墊環(huán)不佳。4、密封箱不平。5、機(jī)械密封安裝沒有達(dá)到應(yīng)有的壓縮量。十、常見的滲漏現(xiàn)象機(jī)械密封滲漏的比例占全部維修泵的50%以上，機(jī)械密封的運(yùn)行好壞直接影響到水泵的正常運(yùn)行，現(xiàn)總結(jié)分析如下：1、周期性滲漏（1）泵轉(zhuǎn)子軸向竄動(dòng)量大，輔助密封與軸的過盈量大，動(dòng)環(huán)不能在軸上靈活移動(dòng)。在泵翻轉(zhuǎn)，動(dòng)、靜環(huán)磨損后，得不到補(bǔ)償位移。對(duì)策：在裝配機(jī)械密封時(shí)，軸的軸向竄動(dòng)量應(yīng)小于0．1mm，輔助密封與軸的過盈量應(yīng)適中，在保證徑向密封的同時(shí)，動(dòng)環(huán)裝配后保證能在軸上靈活移動(dòng)（把動(dòng)環(huán)壓向彈簧能自由地彈回來）。（2）密封面潤(rùn)滑油量不足引起干摩擦或拉毛密封端面。威海國(guó)產(chǎn)機(jī)械密封</p><p
