随着液压支架工作阻力越来越大,同时在高可靠性、耐久性等方面也提出了更高的要求。主要通过在新材料、新技术、新工艺等方面进行了试验和研究,在结构件、液压缸和系统清洁度方面进行了推广和应用,取得了良好的效果。
With the hydraulic support work more and more resistance, at the same time in the high reliability, durability, etc. also put forward higher requirements. Mainly through the new materials, new technologies, new technology and other aspects of the test and research, in the structure, hydraulic cylinder and system cleanliness has been promoted and applied, and achieved good results.
