Hydraulic control system and wetland excavator
The invention discloses a hydraulic control system and a wetland excavator. In the hydraulic control system, a main pump and a pilot pump are both communicated with an oil tank, a control valve is respectively communicated with the main pump and a switching valve group, the switching valve group is respectively communicated with a walking motor, an overturning oil cylinder and a lifting motor, a pedal pilot valve and an electromagnetic valve group are both communicated with the pilot pump, the pedal pilot valve is communicated with the pilot side of the control valve and can control the working position of the control valve; and the electromagnetic valve group is communicated with the pilot side of the switching valve group, and the electromagnetic valve group can control the working position of the switching valve group so that the switching valve group can control oil output by the control valve to enter the walking motor or the overturning oil cylinder or the lifting motor. According to the hydraulic control system provided by the invention, the personal safety of a driver in the operation process can be improved, the operation efficiency and convenience are improved, and the error rate is reduced.
本发明公开了一种液压控制系统及湿地挖掘机，该液压控制系统中，主泵和先导泵均连通油箱，控制阀分别与主泵和切换阀组连通，切换阀组分别与行走马达、翻转油缸和升降马达连通，脚踏先导阀和电磁阀组均与先导泵连通，脚踏先导阀与控制阀的先导侧连通，脚踏先导阀能控制控制阀的工作位置；电磁阀组与切换阀组的先导侧连通，电磁阀组能控制切换阀组的工作位置以使切换阀组能控制从控制阀输出的油液进入行走马达、翻转油缸或升降马达。该液压控制系统能提高驾驶员在操作过程中的人生安全，提高操作效率和便利性，降低出错率。
