五一小長假FESTO氣缸*德國費斯托氣缸 氣缸常見問題及原因分析:
1．汽缸是鑄造而成的，汽缸出廠后都要經(jīng)過時效處理，使汽缸在住鑄造過程中所產生的內應力*消除。如果時效時間短，那么加工好的汽缸在以后的運行中還會變形。 　　
2．汽缸在運行時受力的情況很復雜，除了受汽缸內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對靜止部分的反作用力，以及各種連接管道冷熱狀態(tài)下對汽缸的作用力，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．汽缸的負荷增減過快，特別是快速的啟動、停機和工況變化時溫度變化大、暖缸的方式不正確、停機檢修時打開保溫層過早等，在汽缸中和發(fā)蘭上產生很大的熱應力和熱變形。 　　
4．汽缸在機械加工的過程中或經(jīng)過補焊后產生了應力，但沒有對汽缸進行回火處理加以消除，致使汽缸存在較大的殘余應力，在運行中產生*的變形。 　　
5．在安裝或檢修的過程中，由于檢修工藝和檢修技術的原因，使內缸、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，運行后產生巨大的膨脹力使汽缸變形。 　　
6．使用的汽缸密封劑質量不好、雜質過多或是型號不對；汽缸密封劑內若有堅硬的雜質顆粒就會使密封面難以緊密的結合。 　　
7．汽缸螺栓的緊力不足或是螺栓的材質不合格。汽缸結合面的嚴密性主要靠螺栓的緊力來實現(xiàn)的。機組的起停或是增減負荷時產生的熱應力和高溫會造成螺栓的應力松弛. 163447 DNC-80-25-PPV
