                                        氣瓶水壓試驗機的試驗步驟介紹

                                        1、排氣:

                                        建議人工進行氣瓶預充,之后可進行低壓預充排氣。

                                        2、耐壓試驗:

                                        裝夾好工件,增壓泵開始工作,當壓力保壓壓力時,增壓泵停止工作,保壓一段時間后,記錄量杯及電子秤的數據。開啟卸荷閥,試壓結束。

                                        3、異常卸壓:

                                        系統壓力不斷增加,在試驗過程中強行按“停止”按鈕,PC發出指令,PLC做出相關動作,高壓泵由于沒有氣源,而停止工作,不再產生動力,同時氣動閥開啟,系統缷壓。
