随着生产技术的发展与进步,液压技术和液压元件得到越来越广泛的应用。目前,我国有许多科研单位、大专院校在研究液压技术,生产液压元件的工厂已有上百家。元件质量的优劣直接影响液压传动系统使用的稳定性和可靠性,影响工程效率,甚至危及操作者的人身安全。下面用在钻车上的液压元件在使用中的问题和改进情况介绍如下: 1.油缸双向液压锁的改进 (1)弹簧与阀孔我厂生产的CLQ15型履带式露天潜孔钻车的液压传动系统用的油缸,是国内专业厂家生产。在使用中发现钻车钻臂有下降现象,最严重的为24小时下降300毫米。装配
With the development of production technology and progress, hydraulic technology and hydraulic components are more and more widely used. At present, there are hundreds of scientific research institutes and tertiary institutions in our country which are engaged in the research of hydraulic technology and the production of hydraulic components. The quality of the components directly affects the stability and reliability of the hydraulic drive system, affects the engineering efficiency, and even endangers the safety of the operator. Below used in the drilling of the hydraulic components in the use of the problems and improvements are described below: 1 cylinder bi-directional hydraulic lock improvements (1) spring and valve hole I plant CLQ15 crawler open-air DTH drill hydraulic Transmission system with the cylinder, is a professional manufacturer of domestic production. In use, it was found that there was a drop in the drill arm of the drilling rig, the most serious of which was a drop of 300 mm in 24 hours. assembly
