摘要
对液压支架的几种推移方式作了对比分析,认为采用插装阀构成的支架推移千斤顶差动控制油路,可优化液压系统的配置,提高推溜速度及液压系统的效率和工作可靠性,值得推广。
The several moving forms of hydraulic powered support were analyzed. It can conclude that differential control fluid of moving jack by using plug-in valve can optimize system configuration, improves moving velocity, efficiency and working reliability. It is worth popularizing.
