Design of Energy-saving Device for Energy Recovery and Reuse of Hydraulic Excavator

In order to save energy and reduce emission for hydraulic excavator, a kind of energy-saving device for hydraulic energy recovery and reuse of hydraulic excavator was designed by using flow regeneration and electro-hydraulic proportional throttle valve control technology. The working principles of the energy-saving device and three working conditions were introduced.The electronic control system was composed of motion controller, sensors, solenoid valves and corresponding signal conditioning boards.The measurement and control software of upper computer and lower computer was developed respectively by using C# language and CODESYS programming language. After processing the valve block and purchasing components, a test bench was set up, the excavator energy recovery simulation test and installation test were carried out. The test results show that the device can be used to effectively recover the potential energy of boom descending and the kinetic energy of slewing brake, and the overflow loss is reduced.It lays foundation for further research on the performance of the energy-saving device.
