失效后也容易發(fā)現(xiàn)，本文不再贅述。螺紋密封螺紋密封在泵上一般有兩種形式，一種是螺紋聯(lián)接墊片密封，一種是螺紋加填充濟(jì)密封，二者皆用于小直徑螺紋連接的密封場合。螺紋聯(lián)接墊片密封的密封件是墊片，而螺紋只起提供壓緊力的作用。密封的效果除了墊片的本身性能外。密封面的粗糙度以及與螺紋孔的相對幾何位置精度對密封效果影響也很大。于由密封墊片在擰緊螺紋時不僅承受壓緊力，還承受扭矩，使墊片產(chǎn)生變形甚至損壞，因此，當(dāng)墊片為非金屬時，一般只適用于壓力不高的場合，如果墊片為金屬則適用壓力可達(dá)30Mpa以上。泵上經(jīng)常使用的絲堵，則是另一種螺紋密封形式。由于考慮到絲堵制造的經(jīng)濟(jì)性，一般單靠螺紋的配合不能起到密封作用，往往用生膠帶，密封膠等填充物填充螺紋的密封間隙。其承壓能力取決于螺紋的制造精度和材質(zhì)，與絲堵和螺紋孔的配合形式?jīng)]有關(guān)系。螺紋孔與絲堵無論采用'錐對錐'還是'柱對錐'，密封效果相同，只是使用地域不同而已。我國目前兩種形式同等采用。影響密封效果的常見原因是在加工螺紋底孔時尺寸偏大，使螺紋牙形變短，牙頂變寬，造成密封面減小，當(dāng)密封壓力升高后產(chǎn)生泄漏，甚至將絲堵壓出。青島格蘭富機(jī)械密封件。南昌格蘭富機(jī)械密封件CR45-6</p><p style="text-indent:25px">長春格蘭富機(jī)械密封件。南昌格蘭富機(jī)械密封件CR45-6</p><p> 泵用機(jī)械密封種類繁多，型號各異，但泄漏點(diǎn)主要有五處：1)、軸套與軸間的密封；2)、動環(huán)與軸套間的密封；3)、動、靜環(huán)間密封；4)、對靜環(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，多為動環(huán)或靜環(huán)密封圈存在問題；泄漏量較大時，則表明動、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，再手動盤車觀察，若泄漏量無明顯變化則靜、動環(huán)密封圈有問題；如盤車時泄漏量有明顯變化則可斷定是動、靜環(huán)摩擦副存在問題；如泄漏介質(zhì)沿軸向噴射，則動環(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)時出現(xiàn)的泄漏泵用機(jī)械密封經(jīng)過靜試后，運(yùn)轉(zhuǎn)時高速旋轉(zhuǎn)產(chǎn)生的離心力，介質(zhì)的泄漏。因此，試運(yùn)轉(zhuǎn)時機(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、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：1)、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、靜環(huán)接觸面分離。南昌格蘭富機(jī)械密封件CR45-6</p></p><br
