6 FAQs about [Excavator pilot energy storage tank]
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.
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).
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.
Does Xing use a storage accumulator for a 70-ton excavator?
Xing designed an EERS for a 70-ton excavator that uses a storage accumulator as a reversible energy storage element and a variable pump/motor as an energy conversion element, achieving good energy regeneration results through simulation analysis.
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.
How much energy does a hydraulic excavator need?
The enough energy is also needed to drive the hydraulic excavator by electric motor. Based on the above analysis, a battery of 0.02 kWh is selected for the test bench.
