摘要
分析了目前掩护式支架普遍存在平衡千斤顶安全阀频繁卸液,经常"打高射炮"现象以及护帮千斤顶下腔增压而安全阀频繁卸液等问题,设计开发了矿用液压支架带压浮动控制系统。该技术填补了国内外空白,属创新型技术。
Analyzes a common phenomenon of the roof support whose canopy ram dump liquid frequently,roof support restrained under the lowest position and sprag ram dumping liquid because of the pressure increasing of lower chamber and other issues and meanwhile,it provides,the floating control system of roof support with pressure,a new technology.The technology is an innovative technology at home and abroad.
