液压缸作为工程机械的一个重要组成结构,是促使机械正常运行的动力结构,因此保证液压缸的良好性能是非常有必要的。但是在实际的工程机械检查维修中,却常常发现液压缸的内壁以及活塞或其他结构表面上常常会出现一些孔穴,这些孔穴呈现出蜂窝状,给液压缸的内部结构造成严重损坏。而造成这一现象的根本原因正是气蚀作用。现本文就针对工程机械液压缸气蚀的成因进行分析,继而探讨预防气蚀现象产生的对策措施。 Hydraulic cylinder as an important component of construction machinery structure is to promote the normal operation of mechanical power structure, so to ensure the good performance of the hydraulic cylinder is very necessary. However, in the actual inspection and maintenance of construction machinery, it is often found that there are often holes in the inner wall of the hydraulic cylinder and on the surface of the piston or other structures. These holes are honeycomb-shaped and cause serious damage to the internal structure of the hydraulic cylinder. The root cause of this phenomenon is the cavitation effect. This article is aimed at the cause of formation of hydraulic cylinder hydraulic corrosion analysis, and then explore the prevention of cavitation phenomenon countermeasures.
