摘要
针对EBZ230型悬臂式掘进机在工业性试验中出现液压油缸损坏现象进行了分析,通过改进液压油缸结构的方法,有效地解决了掘进机液压油缸的损坏问题。满足了井下掘进巷道的使用要求,达到了预期的使用效果。
The phenomenon of cutting institutions of the EBZ230 boom-type roadheader in industrial test was analysed and the problem was solved by improving the stucture of cutting institutions oil cylinder and adjusting the flow of hydraulic system, which met the requirements of underground tunneling ,and achieved the desired result.
