6 FAQs about [Excavator system energy storage device]
How many energy storage devices do excavators need?
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.
What are hydraulic energy recovery methods for excavators?
Currently, the mainstream hydraulic energy recovery methods for excavators mainly include the electric energy regeneration system (EERS) and the hydraulic energy regeneration system (HERS).
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 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.
How do electric excavators work?
Firstly, the original battery of the electric excavator is used to recover the gravity potential energy of the boom. Secondly, accumulators with high power density are used as auxiliary energy storage elements.
Can hydraulic excavator boom energy recovery systems save energy?
Scholars have conducted much research into energy saving through hydraulic excavator boom energy recovery systems, but these research results are limited to only one kind of excavator power source.
