Can a four-chamber cylinder system save energy?
The power of the four-chamber cylinder system slowly approaches that of the two-chamber one at the end of the lift phase. It is inferred that the recovered energy from the high-pressure accumulator is run out of for assisted lifting. Therefore, significant energy saving can be achieved with the proposed system. 7. Conclusion and future work
When a hydraulic cylinder is in assistive retraction phase?
When the hydraulic cylinder is in the assistive retraction phases for 2– 5 s, the pump is in the motor mode, such that the pump does not consume energy.
How does a hydraulic cylinder work?
The state of each valve and the effective piston area of the hydraulic cylinder are the same as (3), but with an opposite flow direction. In addition, the high-pressure oil in the C B chamber flows into the high-pressure accumulator to store the potential energy.
What is a centralized hydraulic system?
In such a centralized hydraulic system, a diesel engine drives variable hydraulic pumps as power sources, to provide high-pressure oil fluid.
