The author: Time:2020/12/16

当气源压力通入气缸上室时,检查漏气情况:
        ①气缸盖漏气,通常发生在与定位器连接的两螺纹孔内,表明气缸盖有铸造气孔、砂眼,必须更换新的气缸盖,重做试验;
        ②气缸盖与气缸体、气缸盖与上导套或滑套与上导套的配合面处漏气,其原因可能有两种:一是0形密封圈不合格,二是气缸盖或上导套安装0形密封圈的内槽尺寸加工超差,必须分别检查,更换合格品,重做试验; 
        ⑧支架上小管接头处漏气,其原因有三种:一是活塞本身漏气,二是活塞上0形密封圈与气缸体内壁密封面处漏气,三是装在活骞推杆上的小0形密封圈与活塞内孔的密封面处漏气,必须根据以上原因分别检查处理。
