    山东装载机油缸使用注意事项
    发布时间:2014-8-15 18:54:03    浏览:228次

    装载机油缸必须严格按技术要求安装,不得有任何松动,进出油口接头之间必须加上密封圈并紧固好,以防漏油。装载机油缸在使用时应该注意一下几点:

    1、为了防止活塞杆等细长件弯曲或变形,放置时应用垫木支承均衡。拆卸时应防止损伤活塞杆顶端螺纹、油口螺纹和活塞杆表面、缸套内壁等。
    To prevent the piston rod bent or deformed elongated member such as application support skids equilibrium placement. Demolition should prevent damage to the top of the threaded rod, screw and rod surface oil port, cylinder inner wall.
    2、油缸安装面与活塞的滑动面,应保持一定的平行度和垂直度。
    Fuel tank mounting surface and the sliding surface of the piston, should maintain a certain parallelism and verticality.
    3、油缸中心线应与负载力的作用线同心,以避免引起例向力。否则密封体或活塞易磨损。
    Cylinder centerline line of action should be concentric load force, in order to avoid cases of force. Otherwise, seal or piston wear.
    4、活塞杆端销孔应与耳环销孔(或耳轴)方向一致,否则油缸将受以耳轴为支点的弯曲负载,产生磨损、卡死等现象。
    Rod end pin hole should be the same direction with the earring pin hole (or trunnion), otherwise the cylinder will be subject to the trunnion as a fulcrum bending load, resulting in wear and tear,stuck and so on.
    5、在行程较大、环境温度较高的场合,油缸只能一端固定,另一端保持自由伸缩状态,以防热胀而引起缸体变形。
    In a large stroke, high ambient temperature applications, the cylinder can only be fixed at one end and the other end to keep the state free expansion, to prevent cylinder distortion caused by thermal expansion.
    6、行程较大的油缸,应在缸体和活塞杆中部设置支承,以防自重产生向下弯曲现象。
    Larger cylinder stroke, should be set bearing in the middle of the cylinder and the piston rod to prevent the weight of a downward bending phenomenon.
    7、拆卸时应按顺序进行。由于各种液压缸结构和大小不尽相同,拆卸顺序也稍有不同。一般应放掉油缸两腔的油液,然后拆卸缸盖,最后拆卸活塞与活塞杆,卸卸前后要设法创造条件防止液压缸的零件被周围的灰尘和杂质污染。
    Shall order the demolition. Due to the structure and size of various hydraulic cylinders vary slightly different order of removal. Generally should let go of the two chambers of the cylinder oil,then remove the cylinder head, piston and piston rod finally demolished, after unloading unloading to try to create conditions to prevent the hydraulic cylinder parts are contaminated dust and impurities around.
