1、基本結(jié)構(gòu)副葉輪動(dòng)力密封通常由副葉輪、副葉片（又叫背葉片）、固定導(dǎo)葉和停車(chē)密封裝置等組成，如圖1所示。2、主要部件的作用（1）副葉片的作用是減低泵腔的壓力，達(dá)到平衡軸向力和防止顆粒進(jìn)入密封裝置的目的，常用于抽送含有雜質(zhì)的泵。（2）副葉輪實(shí)際是一個(gè)小離心泵葉輪，靠它產(chǎn)生的壓頭頂住工作葉輪出口的高壓液體向外泄漏。（3）固定導(dǎo)葉的作用是消除液體的旋轉(zhuǎn)，在無(wú)固定導(dǎo)葉時(shí)，副葉輪光背側(cè)的液體以角速度旋轉(zhuǎn)，壓力呈拋物線規(guī)律分布。副葉輪光背側(cè)下部的壓力小于副葉輪外徑處的壓力。如果有固定導(dǎo)葉，則可防止液體旋轉(zhuǎn)，忻州IHE襄樊五二五機(jī)械密封，光背側(cè)下部的壓力和副葉輪外徑處的壓力差不多，這就提高了副葉輪的封堵壓力。（4）油封（停車(chē)密封）作用。因?yàn)楦比~輪只在泵運(yùn)行時(shí)起密封作用，停車(chē)密封裝置可以在泵停車(chē)時(shí)，擋住該余壓液體往外泄漏，忻州IHE襄樊五二五機(jī)械密封。因此，停車(chē)密封應(yīng)具備兩種功能：當(dāng)停車(chē)時(shí)應(yīng)確保及時(shí)封堵，以防泄漏；而運(yùn)行時(shí)則應(yīng)能及時(shí)松開(kāi)，忻州IHE襄樊五二五機(jī)械密封，以免密封面磨損而耗能。在實(shí)際應(yīng)用中，停泵密封采用了三道油封一道擋水環(huán)來(lái)起密封作用。將動(dòng)力密封總成組裝好后替換離心泵機(jī)械密封總成即可。根據(jù)改進(jìn)對(duì)象相應(yīng)改變軸套及前后蓋板外型尺寸。泵除機(jī)械密封（或其它密封裝置）被替換外。LCP7S6-S/SV3-11/61襄樊五二五機(jī)械密封。忻州IHE襄樊五二五機(jī)械密封</p><div

泵用機(jī)械密封是精密的部件，制造精度及安裝精度要求都很?chē)?yán)格，如果裝配不當(dāng)就會(huì)影響密封性能，要正確安裝必須注意以下幾點(diǎn)：一、泵用機(jī)械密封的冷卻和沖洗1、第一種冷卻形式由水泵的出口或高壓端，將輸送的干凈介質(zhì)，直接沖洗密封端面，然后進(jìn)入泵腔內(nèi)，通過(guò)介質(zhì)的不斷循環(huán)，將磨擦端面的的磨擦熱帶走達(dá)到冷卻的效果。2、第二種冷卻方式在第一種冷卻形式的基礎(chǔ)上在靜環(huán)的背部增加一冷卻水套，冷卻效果有所改善，并可以沖洗，收集泄露出來(lái)的液體。當(dāng)密封介質(zhì)溫度＞150℃時(shí)除了在冷卻水套中通過(guò)冷卻水及靜環(huán)背部冷卻外，應(yīng)采取強(qiáng)制冷卻措施。即從泵出口的干凈介質(zhì)應(yīng)預(yù)先經(jīng)熱交換器冷卻至50℃時(shí)。再進(jìn)入密封腔冷卻沖洗，該形式是冷卻效果良好的一種。3、如介質(zhì)中含有顆?；螂s質(zhì)，必須采用過(guò)濾措施，把常溫干凈沖洗液輸入密封腔內(nèi)。二、泵用機(jī)械密封的安裝和技術(shù)要求1、對(duì)機(jī)、泵以及機(jī)械密封的配合部分技術(shù)要求：a.軸彎曲度大不得超過(guò)。b.部件內(nèi)各零件均符合圖紙要求。上緊壓蓋時(shí)應(yīng)在聯(lián)軸器找正后進(jìn)行，壓緊螺絲應(yīng)均上緊，防止法蘭面偏斜。c.彈簧的壓縮量按圖紙規(guī)定進(jìn)行允許誤差±2mm。軸在安裝機(jī)械密封處的振擺量不得大于。軸的軸向竄動(dòng)量不允許大于。</p><p> 而大多數(shù)是由于工況變化較大引起的,如抽空導(dǎo)致密封破壞髙溫加劇泵體內(nèi)油氣分離,導(dǎo)致密封失效。造成的原因有:抽空、彈簧折斷、防轉(zhuǎn)銷(xiāo)切斷、靜環(huán)損傷、環(huán)的密封表面擦傷或損壞、泄漏液形成的結(jié)晶物質(zhì)等使密封副損壞。采取辦法:應(yīng)及時(shí)調(diào)換損壞的密封零部件;防止抽空現(xiàn)象發(fā)生;采取有效措施消除泄漏液所形成的結(jié)晶物質(zhì)的影響等。④停車(chē)后啟動(dòng)漏損造成的原因有:彈簧銹住失去作用、摩擦副表面結(jié)焦或產(chǎn)生水垢等消除的辦法:更換彈簧或擦去彈簧的銹漬,采取有效措施消除結(jié)焦及水垢的形成⑤安裝靜試時(shí)發(fā)生泄漏不銹鋼耐腐蝕泵機(jī)械密封安裝調(diào)試好后,一般要進(jìn)行靜試,觀察泄漏量。如泄漏量小于10滴/min,則可認(rèn)為在正常范圍內(nèi):如泄漏量比⑩0滴/min大,一般為動(dòng)環(huán)或靜環(huán)密封圈存在問(wèn)題:泄漏量較大時(shí)且向四周?chē)娚?則表明動(dòng)、靜環(huán)摩擦副間存在問(wèn)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(pán)車(chē)觀察。若泄漏量無(wú)明顯變化,則靜、動(dòng)環(huán)密封圈有問(wèn)題;如盤(pán)車(chē)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(wèn)題。如泄漏介質(zhì)沿軸向噴射,則動(dòng)環(huán)密封圈存在問(wèn)題居多;泄漏介質(zhì)向四周?chē)娚浠驈乃鋮s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。LCF40/250襄樊五二五機(jī)械密封。</p><div
