Three solenoid valves on the excavator energy storage device

What is a hydraulic excavator energy saving system?

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.

Can intelligent control strategies improve the control precision of excavator energy saving systems?

Additionally, there is potential for research in developing intelligent control strategies for the TCA-based energy saving system, aiming to elevate the control precision of excavator energy saving systems to a higher level. Cheng Yang: Methodology, Formal analysis, Writing – original draft.

How intelligent hydraulic excavator control system based on PID method?

Design of Intelligent Hydraulic Excavator Control System Based on PID Method Abstract. Most of the domestic designed hydraulic excavators adopt the stant power design method and set 85%~90% of engine power as the hydraulic system adoption power, it causes high energy loss due to mismatching of between the engine and the pump.

Can a hydraulic excavator save energy?

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.

What is the difference between electronic control system and excavator?

Based on research with colleges and universities, domestic company has core technology on fault monitor system in excavator, while electronic control has a certain gap between domestic and foreign company. So, there is still and economic value for researching on electronic control system and energy for excavator.

Can a three-chamber accumulator save energy in excavator boom?

This study introduces a novel energy saving system for recovering and reusing the potential energy of excavator boom. The system is based on three-chamber accumulator (TCA) and offers high energy recovery efficiency while maintaining excellent boom speed control performance.
