                                        井下安全閥液壓控制試驗系統的原理

                                        2015-02-05 0

                                        井下安全閥是一種安裝于油管特定位置與封隔器配合防止發生井噴等惡性事故,保證油氣井生產安全的裝置。井下安全閥系統是按照美國石油協會API 14A標準下完成井下安全閥的驗證試驗和功能試驗的設備。井下安全閥試驗系統中非常重要的一個部分就是液壓控制臺

                                        液壓控制實驗系統的主要功能是在井下安全閥進行性能試驗時提供所需的壓力油,控制井下安全閥在各種試驗狀態下完成預定的打開及關閉動作,并進行數據記錄和分析。

                                        液壓控制試驗系統主要由動力源,壓力泵,電氣及液壓控制閘閥,液壓輔助元件等部分組成。系統動力由壓縮空氣提供,采用氣動液體增壓泵增壓,利用電氣比例閥調節驅動氣壓從而控制氣動增壓泵輸出液壓,運用氣液聯合控制的方式進行壓力控制。
