Efficient and energy-saving road sweeper hydraulic system
The invention provides an efficient and energy-saving road sweeper hydraulic system, and belongs to the technical field of road sweepers. The efficient and energy-saving road sweeper hydraulic system comprises a hydraulic pump, a hydraulic oil tank, an oil inlet pipe, an oil return pipe and an execution module, wherein the oil inlet pipe is connected with the hydraulic pump, the oil return pipe is connected with the hydraulic oil tank, and a plurality of execution oil cylinders are arranged in the execution module. All throttling speed regulating valves in a traditional road sweeper hydraulic system re omitted, the movement speed of each execution oil cylinder is completed through one hydraulic element of a flow-adjustable reversing valve, the system cost is reduced, the overflow pressure of each execution oil cylinder is adjusted according to the actual requirement of the overflow pressure of each execution oil cylinder, by means of a pressure-adjustable overflow valve, power consumption can be generated according to the actually calibrated overflow pressure value in the pressure building process after the execution oil cylinders move in place, and compared with a traditional system which generates power consumption according to the maximum pressure value, power consumption is greatly reduced, and system efficiency is improved.
本发明提供了一种高效节能的扫路车液压系统，属于扫路车技术领域。它包括液压泵、液压油箱、进油管、回油管和执行模块，所述的进油管与液压泵连接，所述的回油管与液压油箱连接，所述的执行模块内设有若干个执行油缸。取消了传统扫路车液压系统中的所有节流调速阀，各个执行油缸的运动速度通过可调流量换向阀一个液压元件来完成，降低了系统成本，根据各个执行油缸的溢流压力的实际需求，通过可调压力溢流阀能够使各执行油缸运动到位后的憋压过程以实际标定的溢流压力值来产生功耗，相比传统系统以最大压力值来产生功耗，大大减小了功率损耗，提高了系统效率。
