汽缸是鑄造而成的，汽缸出廠后都要經過時效處理，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。
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下對汽缸的作用力，在這些力的相互作用下，汽缸易發生塑性變形造成泄漏。
汽缸的(de)負荷增減過快，特別是快速的(de)啟動、停機(ji)和(he)工況變(bian)化時溫度變(bian)化大、暖缸的(de)方式不正(zheng)確、停機(ji)檢(jian)修時打開保(bao)溫層(ceng)過早(zao)等，在汽缸中和(he)法蘭上產生很大的(de)熱應(ying)力(li)和(he)熱變(bian)形。

編碼器（encoder）是將信號（如比特流）或數據編制、轉換為可用以通訊、傳輸和存儲之形式的設備。編碼器是把角位移或直線位移轉換成電信號的一種裝置。前者稱為碼盤，后者稱為碼尺。按照讀出方式編碼器可以分為接觸式和非接觸式兩種；編碼器產生電信號后由數控制置CNC、可編程邏輯控制器PLC、控制系統等來處理。這些傳感器主要應用在下列方面：機床、材料加工、電動機反饋系統以及測量和控制設備。在ELTRA編碼器中角位移的轉換采用了光電掃描原理。讀數系統是基于徑向分度盤的旋轉，該分度由交替的透光窗口和不透光窗口構成的。此系統全部用一個紅外光源垂直照射，增量式編碼器是將位移轉換成周期性的電信號，再把這個電信號轉變成計數脈沖，用脈沖的個數表示位移的大小。編碼器的每一個位置對應一個確定的數字碼，因此它的示值只與測量的起始和終止位置有關，而與測量的中間過程無關。旋轉增量式編碼器以轉動時輸出脈沖，通過計數設備來知道其位置，當編碼器不動或停電時，依靠計數設備的內部記憶來記住位置。這樣，當停電后，編碼器不能有任何的移動，當來電工作時，編碼器輸出脈沖過程中，也不能有干擾而丟失脈沖，不然，計數設備記憶的零點就會偏移，而且這種偏移的量是無從知道的，只有錯誤的生產結果出現后才能知道。解決的方法是增加參考點，編碼器每經過參考點，將參考位置修正進計數設備的記憶位置。在參考點以前，是不能保證位置的準確性的。為此，在工控中就有每次操作先找參考點，開機找零等方法。這樣的編碼器是由碼盤的機械位置決定的，它不受停電、干擾的影響。編碼器是把角位移或直線位移轉換成電信號的一種裝置。前者成為碼盤，后者稱碼尺．按照讀出方式編碼器可以分為接觸式和非接觸式兩種．接觸式采用電刷輸出，一電刷接觸導電區或絕緣區來表示代碼的狀態是“1”還是“0”；非接觸式的接受敏感元件是光敏元件或磁敏元件，采用光敏元件時以透光區和不透光區來表示代碼的狀態是“1”還是“0”。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。
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，如果應力不足，螺栓的預緊力就會逐漸減小。如果汽缸的螺栓材質不好，螺栓在長時間的運行當中，在熱應力和汽缸膨脹力的作用下被拉長，發生塑性變形或斷裂，緊力就會不足，使汽缸發生泄漏的現象。
