在工程机械的使用中,液压缸油封的损坏是常见的故障,修理更换时由于无专用工具,一些修理工常用薄铜皮或薄铁皮导向而强行打入,但因卡键槽离液压缸缸口太远,加之油封张力的作用,常使装配极为困难或剪坏油封,不得不重新装配或更换油封。通过实际工作,我们找到了一种简便可靠的更换液压缸油封的办法,具体操作如下: (1)正确地选用油封,即应分清孔用和轴用油封,并保证尺寸正确。 (2)拆卸液压缸。 (3)更换密封件。对于国产机型,可一次性全套更换;对于进口机型,可酌情
In the use of construction machinery, the hydraulic cylinder seal damage is a common failure, there is no special tool for repair and replacement, some mechanics often use thin copper or thin metal guide and forced into, but because of the keyway from the cylinder cylinder mouth too Far, combined with the role of oil seal tension, often make the assembly extremely difficult or cut oil seal, had to reassemble or replace the oil seal. Through practical work, we found a simple and reliable way to replace the hydraulic cylinder oil seal, the specific operation is as follows: (1) The correct choice of oil seal, that is, should distinguish between hole and shaft seal, and ensure the correct size. (2) Disassemble the hydraulic cylinder. (3) Replace the seal. For domestic models, a one-time full replacement; for imported models, discretionary
