                                        2016-11-08 0

                                        我司專業研發生產閥門靜壓壽命試驗機,適用于閥門帶(靜)壓狀態下的開關壽命、脈沖(疲勞/壓力交變)壽命測試。今天給大家簡單介紹關于閥門靜壓壽命試驗機工作原理,如下:

                                        連接好被測試閥門→通過控制臺上調壓閥設定好系統的介質壓力→人工測定閥門正常開關扭矩→設定好輸出扭矩并連接好閥門→調整好轉速、行程、設定好限位開關→開始→介質壓力上升→去動機構帶動閥門開啟→達到設定的開啟位置后反向關閉→泄掉后段壓力→閥門再開啟、關閉、循環。

                                        閥門靜壓壽命試驗機可以程序設定好循環次數,在多少次停止后通氣檢查氣密性,通過泄漏量判斷是否合格。

                                        下面是原理圖:
