摘要: 针对煤矿用特种防爆柴油机车辆全液压驱动车辆行走系统采用液控闭式系统所存在的弊端,在研究了非煤矿用车辆用全液压驱动闭式行走系统电液控制技术的基础上,设计出了适合于煤矿用特种防爆柴油机车辆用全液压驱动车辆防爆电控闭式行走控制系统并在矿用特种防爆全液压驱动车辆行走控制系统中得以应用。经过1年来的推广试验,结果表明该系统能实现防爆发动机与液压系统的自动匹配,能提高发动机的功率利用率,可获得比现有液控闭式行走系统更好的综合性能(爬坡能力提高10%以上,油耗降低5%以上)。

Abstract: Abstract: In view of vehicle hydraulic driven by hydraulic control defects existing in closed system of vehicle driving system of special explosion-proof diesel used in coal mine, in the study of the vehicle with full hydraulic drive based closed running system of electro-hydraulic control technology of non coal mines, design suitable for coal mine special explosion-proof diesel vehicle full hydraulic drive vehicle explosion-proof electric closed running control system and in the mining special explosion-proof hydraulic drive vehicle can be applied in the control system. After the promotion of a one-year experiment show that this system can realize the automatic matching of explosion-proof motor and hydraulic system, improve the utilization rate of engine power, can obtain the comprehensive performance than the existing hydraulic closed type walking system better. (climbing ability is improved by more than 10%, fuel consumption reduced by more than 5%).

Key words: Keywords: hydraulic closed running system, closed walking system explosion-proof electric control system, design, Research, Application
