A pure electric mining dump truck hydraulic system comprises a hydraulic steering system and a hydraulic lifting system, and the hydraulic steering system comprises a steering plunger pump, an energy accumulator, a multi-way valve assembly, a steering valve, a two-way unloading valve, a steering cylinder and an electromagnetic reversing valve; the lifting system comprises a gear pump, an overflow valve, a lifting valve, an oil suction filter, a lifting control handle, a pilot valve block, a bounce valve, a lifting cylinder and a lifting hydraulic oil tank. And the steering plunger pump and the lifting plunger pump are driven by a double-shaft extension motor. A single motor can drive the two hydraulic systems to operate stably, space is saved, meanwhile, jamming and preparation time of the two systems during operation and switching are shortened, energy is saved, and efficiency is improved.

    一种纯电动矿用自卸车液压系统,包括液压转向系统和液压举升系统,所述液压转向系统包括转向柱塞泵、蓄能器、多路阀总成、转向阀、双向卸荷阀、转向缸和电磁换向阀;所述举升系统包括齿轮泵、溢流阀、举升阀、吸油过滤器、举升控制手柄、先导阀块、反跳阀、举升缸和举升液压油箱;所述转向柱塞泵和举升柱塞泵由双轴伸电机驱动。单个电机即可带动两个液压系统平稳运行,节省了空间的同时也使得两个系统在运行和切换时的卡顿和准备时间减少,节省能源、增加效率。
