Then, a hydraulic excavator energy saving system based on three-chamber accumulator is proposed, which can store and reuse the energy loss from throttling and overflow of the hydraulic system without changing the hydraulic system of the excavator.
In order to address these issues, a hydraulic excavator energy saving system based on a three-chamber accumulator is proposed. Firstly, the conventional piston-type hydraulic accumulator is integrated with the hydraulic cylinder to form a three-chamber accumulator, which has a pressurizing function during energy storage.
First, potential recoverable energy sources in excavator mechanisms are analyzed. Next, energy regeneration systems are classified according to energy storage devices and their development is comprehensively reviewed through the state-of-art.
The regeneration system always requires at least one energy storage device. However, using a single storage device is difficult to meet the need for energy recuperation as well as performance satisfaction of excavators. Some researches combine two independent energy storage devices to form a combined energy storage system.
The energy is stored by being compressed to high pressure inside the accumulator. So that recovered energy can be used immediately to actuators in emergencies. Fig. 15. Schematic of the ERS using hydraulic storage. The energy regeneration efficiency of hydraulic ERS is proportional to the volume of the hydraulic accumulator.
Currently, the mainstream hydraulic energy recovery methods for excavators mainly include the electric energy regeneration system (EERS) and the hydraulic energy regeneration system (HERS).
