HG24混凝土布料机液压系统的改进

Improvement of the Hydraulic System of HG24 Concrete Placing Boom

本文阐述了HG24混凝土布料机日常工作状况和液压系统在使用过程中出现的臂架油缸啸叫问题,指出该故障对系统稳定性的危害,以第三臂油缸为例对其产生的机理作出详细的讨论,并通过在油缸上添加节流阀或在油缸上改用平衡阀等方法进行系统优化,得出较佳的解决方案。

The paper for HG24 concrete placing boom, which illustrates the normal working condition and the noise problem of hydraulic system during use. The third hydro-cylinder is the typical case, noise problem will be a hazard for system stability. Analyzing the cause for the problem and the solutions can be found in this paper. Adding the throttle and changing the balanced valve to improve the system is the better ideas for noise problem.
