高壓油管是高壓油路的組成部分，要求油管需要承受一定的油壓而且有一定的疲勞強度，保證管路密封要求。需要進行高壓油管氣密性檢測，車用高壓油管主要出現(xiàn)在高壓噴射的柴油機和高壓噴射的直噴汽油機中，能承受發(fā)動機運轉過程中所需的油壓。那么廠家在生產(chǎn)中是如何檢測高壓油管氣密性檢測呢？要給大家分享的案例就是高壓油管氣密性測試方案。首先我們來分析一下高壓油管氣密性檢測的難點，高壓油管氣密性檢測的難點主要在于高壓油管接頭部位，它的接頭是由至少兩個部件相互焊接而成，這樣就必須保證焊接位置的密封性良好，只有保障焊接位置密封性良好，才能使整個油管接頭的密封性得到保障，這樣才可以安裝到汽車上使用，保障汽車的安全，消除不好的安全隱患。要檢測高壓油管氣密性，我們首先得選擇一臺壓力范圍大、精度高、穩(wěn)定性好的氣密性檢測設備，我們選擇的檢測儀器是深圳希立儀器設備有限公司的SLA直壓系列氣密性檢測儀，這個系列有多通道和單通道兩種儀器，這次我們選擇單通道儀器即可。因為高壓油管兩端連接著接頭，整體為彎管狀結構，無法直接充氣檢測，所以需要設計檢測輔助工裝，經(jīng)過模具工裝設計師的考慮，我們較終設計出的輔助工裝。太倉爾鑫起重設備配件有限公司致力于提供油管，歡迎您的來電哦！</p><div
