Electric loader hydraulic system and control method thereof
The invention relates to the technical field of electric loaders, in particular to an electric loader hydraulic system and a control method thereof. In the application, corresponding monitoring sensing devices are respectively arranged aiming at a movable arm lifting/descending travel switch, a bucket retracting/tipping travel switch, a forward/backward gear switch and a hydraulic system pressure switch in a hydraulic system of the electric loader, so that the actual intention of an operator of the electric loader is judged; and according to a preset oil pump motor control method, the oil pump motor controller starts the oil pump motor and adjusts the operation speed of the oil pump motor by receiving the monitoring signals corresponding to the monitoring sensing devices so as to adjust the input power of the oil pump, and under the condition that the use working condition of the electric loader is met, the energy consumption waste of the hydraulic system is reduced, and the energy consumption is reduced. And finally, the efficiency of the hydraulic system is improved.
本发明涉及电动装载机技术领域，具体涉及一种电动装载机液压系统及其控制方法。本申请中，通过针对电动装载机液压系统中的动臂提升/下降行程开关、铲斗收斗/翻斗行程开关、前进/后退挡开关以及液压系统压力开关，分别设置对应的监测传感装置，以判断电动装载机操作人员的实际意图；以及，根据预设的油泵电机控制方法，油泵电机控制器通过接收每个监测传感装置对应的监测信号，启动油泵电机并对其运转速度进行调节，以调节油泵的输入功率，在满足电动装载机使用工况的情况下，通过减小液压系统能耗浪费，最终实现液压系统效率的提高。
