原裝*日本SMC氣缸上海折扣出售
1.汽缸是鑄造而成的,汽缸出廠后都要經(jīng)過(guò)時(shí)效處理,使汽缸在住鑄造過(guò)程中所產(chǎn)生的內(nèi)應(yīng)力*消除。如果時(shí)效時(shí)間短,那么加工好的汽缸在以后的運(yùn)行中還會(huì)變形。 2.汽缸在運(yùn)行時(shí)受力的情況很復(fù)雜,除了受汽缸內(nèi)外氣體的壓力差和裝在其中的各零部件的重量等靜載荷外,還要承受蒸汽流出靜葉時(shí)對(duì)靜止部分的反作用力,以及各種連接管道冷熱狀態(tài)下對(duì)汽缸的作用力,在這些力的相互作用下,汽缸易發(fā)生塑性變形造成泄漏。 3.汽缸的負(fù)荷增減過(guò)快,特別是快速的啟動(dòng)、停機(jī)和工況變化時(shí)溫度變化大、暖缸的方式不正確、停機(jī)檢修時(shí)打開(kāi)保溫層過(guò)早等,在汽缸中和發(fā)蘭上產(chǎn)生很大的熱應(yīng)力和熱變形。 4.汽缸在機(jī)械加工的過(guò)程中或經(jīng)過(guò)補(bǔ)焊后產(chǎn)生了應(yīng)力,但沒(méi)有對(duì)汽缸進(jìn)行回火處理加以消除,致使汽缸存在較大的殘余應(yīng)力,在運(yùn)行中產(chǎn)生*的變形。 5.在安裝或檢修的過(guò)程中,由于檢修工藝和檢修技術(shù)的原因,使內(nèi)缸、汽缸隔板、隔板套及汽封套的膨脹間隙不合適,或是掛耳壓板的膨脹間隙不合適,運(yùn)行后產(chǎn)生巨大的膨脹力使汽缸變形。 6.使用的汽缸密封劑質(zhì)量不好、雜質(zhì)過(guò)多或是型號(hào)不對(duì);汽缸密封劑內(nèi)若有堅(jiān)硬的雜質(zhì)顆粒就會(huì)使密封面難以緊密的結(jié)合。 7.汽缸螺栓的緊力不足或是螺栓的材質(zhì)不合格。汽缸結(jié)合面的嚴(yán)密性主要靠螺栓的緊力來(lái)實(shí)現(xiàn)的。機(jī)組的起停或是增減負(fù)荷時(shí)產(chǎn)生的熱應(yīng)力和高溫會(huì)造成螺栓的應(yīng)力松弛,如果應(yīng)力不足,螺栓的預(yù)緊力就會(huì)逐漸減小。如果汽缸的螺栓材質(zhì)不好,螺栓在長(zhǎng)時(shí)間的運(yùn)行當(dāng)中,在熱應(yīng)力和汽缸膨脹力的作用下被拉長(zhǎng),發(fā)生塑性變形或斷裂,緊力就會(huì)不足,使汽缸發(fā)生泄漏的現(xiàn)象。 8.汽缸螺栓緊固的順序不正確。一般的汽缸螺栓在緊固時(shí)是從中間向兩邊同時(shí)緊固,也就是從垂弧zui大處或是受力變形zui大的地方緊固,這樣就會(huì)把變形zui大的處的間隙向汽缸前后的自由端轉(zhuǎn)移,zui后間隙漸漸消失。如果是從兩邊向中間緊,間隙就會(huì)集中于中部,汽缸結(jié)合面形成弓型間隙,引起蒸汽泄漏
