The author: Time:2020/12/16

當(dāng)氣源壓力通入氣缸上室時,檢查漏氣情況:
        ①氣缸蓋漏氣,通常發(fā)生在與定位器連接的兩螺紋孔內(nèi),表明氣缸蓋有鑄造氣孔、砂眼,必須更換新的氣缸蓋,重做試驗;
        ②氣缸蓋與氣缸體、氣缸蓋與上導(dǎo)套或滑套與上導(dǎo)套的配合面處漏氣,其原因可能有兩種:一是0形密封圈不合格,二是氣缸蓋或上導(dǎo)套安裝0形密封圈的內(nèi)槽尺寸加工超差,必須分別檢查,更換合格品,重做試驗; 
        ⑧支架上小管接頭處漏氣,其原因有三種:一是活塞本身漏氣,二是活塞上0形密封圈與氣缸體內(nèi)壁密封面處漏氣,三是裝在活騫推桿上的小0形密封圈與活塞內(nèi)孔的密封面處漏氣,必須根據(jù)以上原因分別檢查處理。
