泵用機(jī)械密封種類繁多，型號各異，但泄漏點主要有五處：1）軸套與軸間的密封；2）動環(huán)與軸套間的密封；3）動，蚌埠化工機(jī)械密封、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，蚌埠化工機(jī)械密封.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，蚌埠化工機(jī)械密封，會壓制介質(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：（l）操作中，因抽空、氣蝕、憋壓等異常現(xiàn)象，引起較大的軸向力，使動、靜環(huán)接觸面分離；。新吳區(qū)波紋管機(jī)械密封件。蚌埠化工機(jī)械密封</p><div
