Hydraulic system for controlling multiple rotary motors of land leveler and control method of hydraulic system
The invention discloses a hydraulic system for controlling multiple rotary motors of a land leveler and a control method of the hydraulic system, and belongs to the field of electro-hydraulic control of engineering machinery. The system comprises a hydraulic oil tank, a reversing valve, a diverter valve, a plurality of turbine boxes, a plurality of rotary motors, a plurality of bidirectional overload valves, a plunger pump, an oil suction filter and the like, and a plurality of rotary motor control loops are finally formed through connection of all the elements. The multiple rotary motors can move at the same rotating speed and the same pressure, so that it is guaranteed that the multiple turbine boxes move at the same rotating speed, stress is uniform, and movement is smooth.
本发明公开了一种平地机多个回转马达控制液压系统及其控制方法，属于工程机械的电液控制领域。所述系统包括液压油箱、换向阀、分流阀、多个涡轮箱、多个回转马达、多个双向过载阀、柱塞泵和吸油过滤器等，通过所述各元件的连接，最终形成多个回转马达控制回路。本发明可实现多个回转马达以相同转速，相同压力运动，从而保证多个涡轮箱以相同转速运动，受力均匀，运动平顺。
