六大UHB化工泵機(jī)械密封檢修過(guò)程中存在的誤區(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(guò)大，可導(dǎo)致摩擦副急劇磨損，瞬間燒損；過(guò)度的壓縮使彈簧失去調(diào)節(jié)動(dòng)環(huán)端面的能力，導(dǎo)致密封失效。2、動(dòng)環(huán)密封圖越緊越好。其實(shí)動(dòng)環(huán)密封圈過(guò)緊有害無(wú)益。是加劇密封圈與軸套間的磨損，泄漏；二是增大了動(dòng)環(huán)軸向調(diào)整、移動(dòng)的阻力，在工況變化頻繁時(shí)無(wú)法適時(shí)進(jìn)行調(diào)整；三是彈簧過(guò)度疲憊易損壞；四是使動(dòng)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(duì)較緊密封效果會(huì)好些，但過(guò)緊也是有害的。是引起靜環(huán)密封因過(guò)度變形，影響密封效果；二是靜環(huán)材質(zhì)以石墨居多，般較脆，過(guò)度受力易引起碎裂；三是安裝、拆卸困難，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(jiàn)的。一般認(rèn)為，軸間泄漏就是葉輪鎖母沒(méi)鎖緊，其實(shí)導(dǎo)致軸間泄漏的因素較多，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(guò)長(zhǎng)等都會(huì)導(dǎo)致軸間泄漏。鎖母鎖緊過(guò)度只會(huì)導(dǎo)致軸間墊過(guò)早失效，相反適度鎖緊鎖母，使軸間墊始終保持定的壓縮彈性。馬鞍山格蘭富機(jī)械密封件CR10-05懷化格蘭富機(jī)械密封件。</p><div

柔性石墨填料等用于離心泵的軟填料，它們的性能好，適應(yīng)的范圍也廣，值得應(yīng)用。其三是散熱，冷卻能力的設(shè)計(jì)：例如圖中的圖結(jié)構(gòu)就存在散熱，冷卻能力不足的問(wèn)題，即便是圖中的圖結(jié)構(gòu)，由于水環(huán)的存水量太小，冷卻能力還是受限的，而圖中的圖結(jié)構(gòu)就比較完美地解決了散熱與冷卻能力的設(shè)計(jì)問(wèn)題。電站閥常用的自密封結(jié)構(gòu)有楔形墊組合密封應(yīng)力松弛造成密封工作穩(wěn)定性差泵用軟填料密封結(jié)構(gòu)中的軟填料在軸向壓緊調(diào)節(jié)裝置的作用下，內(nèi)部將產(chǎn)生軸向和徑向應(yīng)力，當(dāng)然，周向同樣會(huì)產(chǎn)生應(yīng)力。隨著泵的長(zhǎng)期工作，軟填料不斷在磨耗，若不及時(shí)調(diào)節(jié)，其將產(chǎn)生所謂“應(yīng)力松弛”。一旦產(chǎn)生應(yīng)力松弛，密封就會(huì)受到影響，將致使密封工作穩(wěn)定性變差。軟填料自動(dòng)補(bǔ)償能力問(wèn)題既然軟填料在工作中與軸形成滑動(dòng)摩擦，其磨損是較大的，磨損后填料與軸桿，填料箱內(nèi)壁之間的間隙加大，如果沒(méi)有自動(dòng)補(bǔ)償機(jī)構(gòu)，則隨著軟填料的磨損，泄漏量將逐漸增大。但未達(dá)到流淌程度成批生產(chǎn)某種幾何形狀的密封墊片時(shí)，應(yīng)利用模具沖壓；批量少的可用法蘭密封面涂顏料貼印的方法進(jìn)行剪裁制造。結(jié)構(gòu)設(shè)計(jì)的合理與優(yōu)化①改進(jìn)密封結(jié)構(gòu)，在填料環(huán)之間加入自動(dòng)補(bǔ)償機(jī)構(gòu)。填料沿填料長(zhǎng)度涵方向的徑向應(yīng)力分布不均勻。馬鞍山格蘭富機(jī)械密封件CR10-05</p></p><br
