二、泵用機(jī)械密封檢修中的幾個誤區(qū)1．彈簧壓縮量越大密封效果越好。其實(shí)不然，彈簧壓縮量過大，可導(dǎo)致摩擦副急劇磨損，瞬間燒損；過度的壓縮使彈簧失去調(diào)節(jié)動環(huán)端面的能力，導(dǎo)致密封失效。2．動環(huán)密封圖越緊越好。其實(shí)動環(huán)密封圈過緊有害無益。一是加劇密封圈與軸套間的磨損，泄漏；二是增大了動環(huán)軸向調(diào)整、移動的阻力，在工況變化頻繁時(shí)無法適時(shí)進(jìn)行調(diào)整；三是彈簧過度疲勞易損壞；四是使動環(huán)密封圈變形，影響密封效果。3．靜環(huán)密封圈越緊越好。靜環(huán)密封圈基本處于靜止?fàn)顟B(tài)，相對較緊密封效果會好些，但過緊也是有害的。一是引起靜環(huán)密封因過度變形，影響密封效果；二是靜環(huán)材質(zhì)以石墨居多，一般較脆，過度受力極易引起碎裂；三是安裝、拆卸困難，黑河安德里茲泵用機(jī)械密封ACP125-250，極易損壞靜環(huán)。4．葉輪鎖母越緊越好。機(jī)械密封泄漏中，軸套與軸之間的泄漏（軸間泄漏）是比較常見的。一般認(rèn)為，軸間泄漏就是葉輪鎖母沒鎖緊，其實(shí)導(dǎo)致軸間泄漏的因素較多，黑河安德里茲泵用機(jī)械密封ACP125-250，如軸間墊失效，偏移，軸間內(nèi)有雜質(zhì)，軸與軸套配合處有較大的形位誤差，接觸面破壞，軸上各部件間有間隙，軸頭螺紋過長等都會導(dǎo)致軸間泄漏。鎖母鎖緊過度只會導(dǎo)致軸間墊過早失效，相反適度鎖緊鎖母，黑河安德里茲泵用機(jī)械密封ACP125-250，使軸間墊始終保持一定的壓縮彈性。銅仁安德里茲泵用機(jī)械密封JCS1C-43-QREO-GA-192038。黑河安德里茲泵用機(jī)械密封ACP125-250</p><div

使彈簧旋緊而不是旋松，這是必須指出的。旋轉(zhuǎn)式機(jī)械密封傳動座和動環(huán)的傳動方式1）銷釘傳動。通過推環(huán)，在推環(huán)和動環(huán)之間用銷釘實(shí)現(xiàn)傳動（圖35），這種傳動方式多用在小彈簧的結(jié)構(gòu)上。2）突耳傳動。國內(nèi)生產(chǎn)的104型密封即采用此種結(jié)構(gòu)。在動環(huán)外緣制成圓弧槽，而將與此接觸的傳動座壓成突耳，使之嵌入動環(huán)的槽中，實(shí)現(xiàn)傳動（圖13）。這種結(jié)構(gòu)可用于大彈簧，也可用于小彈簧的密封結(jié)構(gòu)。3）并圈彈簧傳動。傳動座與彈簧以及彈簧和動環(huán)之間，完全依靠大彈簧內(nèi)徑的過盈值實(shí)現(xiàn)傳動（圖34），當(dāng)然也有旋向的要求。這種結(jié)構(gòu)都用在大彈簧的密封結(jié)構(gòu)上。4）勾圈彈簧傳動。為了增加并圈彈簧傳動的可靠性，彈簧的兩個端頭制成彎勾形，分別鉤住傳動座和動環(huán)（圖36）。5）離合器傳動。傳動座和動環(huán)（或通過推環(huán)）分別制成方形的凸起和缺口，組裝好后凸起插入缺口中實(shí)現(xiàn)傳動（圖37）。6）波紋管傳動。這種方式是波紋管型密封的特有結(jié)構(gòu)，波紋管兩端分別與傳動座和動環(huán)聯(lián)接，至于聯(lián)接方式依波紋管材料而定。例如，對金屬波紋管，則采用焊接；對于橡膠和四氟波紋管，則采用整體或其他方式聯(lián)接。靜止式機(jī)械密封的動環(huán)的旋轉(zhuǎn)靜止式機(jī)械密封的動環(huán)直接固定在軸（軸套）上，隨軸一起旋轉(zhuǎn)。</p><p> 機(jī)械密封的密封環(huán)之間應(yīng)有一層液體薄膜，具有下列三個作用：1.支持密封受到的大部分水壓負(fù)荷。2.作為潤滑劑，減少密封環(huán)生成的摩擦熱。3.使粗糙接觸小化，從而降低磨損率。4.作為傳熱介質(zhì)，轉(zhuǎn)移密封環(huán)直接區(qū)域的熱能。首先我們要研究密封失效的原因，根據(jù)我的經(jīng)驗(yàn)，有如下：生產(chǎn)上的缺陷；設(shè)計(jì)上的缺陷；缺少培訓(xùn)/技術(shù)；在我們拆卸機(jī)械密封的之前，我們先要想好以下幾點(diǎn)：1.主要的泄漏在哪里?2.在外部件上是否有碎片？3.是否觀察到軸或旋轉(zhuǎn)的密封部件有偏心現(xiàn)象？4.有否與系統(tǒng)相關(guān)的震動/噪音（如氣穴，接合錯位）？5.在“泵”或密封是否存在局部的熱生成？6.在不同的情況下泄漏是否是間歇的，如在不同的溫度下？7.屬何種泄漏，噴射，小滴，水流或流往管道？8.軸承是否有軸向間隙？9.如果是雙端面密封，則檢查隔離液供應(yīng)是否完好。10.密封在軸上的相對位置？拆除密封過程中，我們要注意以下幾點(diǎn)：1.墊片和磨合端面的狀態(tài)？2.軸的情況和尺寸？3.機(jī)器的阻塞/密封氣穴？4.裝到軸上松還是緊？5.機(jī)器的腐蝕？6.機(jī)器里是否有密封碎片？7.在密封安裝到軸上的位置是否有基準(zhǔn)標(biāo)記？8.密封部位的軸的相對硬度？拆除密封的時(shí)候，我們就要注意以下幾點(diǎn)：1.在拆除過程中。韶關(guān)安德里茲泵用機(jī)械密封JCS1C-43-QREO-GA-192038。</p><div

對于離心泵，轉(zhuǎn)速在2950r／min和直徑小時(shí)，可忽略離心力的影響；當(dāng)直徑較大時(shí)，環(huán)座產(chǎn)生的離心力較大，會抵消一部分過盈值，不容忽略。此外，環(huán)座材料的彈性模量不同，采用的過盈值也不同，對于彈性錯量小的材料（如4J42和鈦合金等），過盈值可相應(yīng)大些。我們引用計(jì)算過盈值的公式e=dm（a2一a1）（t—t0），取e=0．002dm有0．002=（a2一a1）（t—t0）可得高使用溫度t=（a2一a1）+t0對于3Cr13、1Cr18Ni9Ti、Icr18Ni12Mo2Ti和哈氏合金B(yǎng)與C，其彈性模量相近，當(dāng)它們與YG6和YGS熱裝時(shí)，高使用溫度見表2(取t。＝22℃)?？紤]離心力的影響和高溫下環(huán)座材料的應(yīng)力松弛后，各種環(huán)座材料的允許使用溫度見圖28，超出此溫度在密封腔中就應(yīng)采取措施，降低溫度。八、輔助密封圈種類動環(huán)和軸（軸套）以及靜環(huán)和壓蓋之間的密封靠輔助密封圈來實(shí)現(xiàn)。它們基本上屬于靜密封，當(dāng)密封端面和軸中心線不垂直時(shí)，動環(huán)密封圈沿軸向有很小的軸向運(yùn)動，其位移量取決于密封端面和軸中心的垂直度誤差、運(yùn)動的次數(shù)和軸轉(zhuǎn)速等。輔助密封圈的種類很多，從材料角度分類有合成橡膠、聚四氟乙烯和柔性石墨等；從斷面形狀分類有圓形、方形、V形、楔形及包覆形密封圈。濱海新區(qū)SAB-35-QRXG-GA121489安德里茲泵用機(jī)械密封。黑河安德里茲泵用機(jī)械密封ACP125-250</p><p
