山東裝載機(jī)油缸使用注意事項(xiàng)

裝載機(jī)油缸必須嚴(yán)格按技術(shù)要求安裝，不得有任何松動，進(jìn)出油口接頭之間必須加上密封圈并緊固好，以防漏油。裝載機(jī)油缸在使用時(shí)應(yīng)該注意一下幾點(diǎn)：

1、為了防止活塞桿等細(xì)長件彎曲或變形，放置時(shí)應(yīng)用墊木支承均衡。拆卸時(shí)應(yīng)防止損傷活塞桿頂端螺紋、油口螺紋和活塞桿表面、缸套內(nèi)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、油缸安裝面與活塞的滑動面，應(yīng)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、油缸中心線應(yīng)與負(fù)載力的作用線同心，以避免引起例向力。否則密封體或活塞易磨損。
Cylinder centerline line of action should be concentric load force, in order to avoid cases of force. Otherwise, seal or piston wear.
4、活塞桿端銷孔應(yīng)與耳環(huán)銷孔(或耳軸)方向一致，否則油缸將受以耳軸為支點(diǎn)的彎曲負(fù)載，產(chǎn)生磨損、卡死等現(xiàn)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、在行程較大、環(huán)境溫度較高的場合，油缸只能一端固定，另一端保持自由伸縮狀態(tài)，以防熱脹而引起缸體變形。
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、行程較大的油缸，應(yīng)在缸體和活塞桿中部設(shè)置支承，以防自重產(chǎn)生向下彎曲現(xiàn)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、拆卸時(shí)應(yīng)按順序進(jìn)行。由于各種液壓缸結(jié)構(gòu)和大小不盡相同，拆卸順序也稍有不同。一般應(yīng)放掉油缸兩腔的油液，然后拆卸缸蓋，最后拆卸活塞與活塞桿，卸卸前后要設(shè)法創(chuàng)造條件防止液壓缸的零件被周圍的灰塵和雜質(zhì)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.
