Directional control valves are critical to almost every hydraulic system on the market! Energy Hydraulics carries a wide selection of the most popular valves on the market.
Energy Mfg. Co. specializes in providing custom hydraulic cylinders, valves, and Williams pumps, tanks, and valves for demanding applications.
In contrast, HERS generally uses accumulators to store hydraulic energy directly in a hydro-pneumatic way, which shortens the energy transmission chain [ , , ]. Yang proposed a hydraulic excavator energy storage system based on three-chamber accumulators that can reduce energy consumption by 44.9 % [ 11 ].
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.
It is seen that the displacement and velocity of the two cylinders are nearly consistent throughout the entire work cycle, which means that the proposed system ensures the symmetric flow in the closed-circuit hydraulic system. Moreover, the speed of the four-chamber cylinder system is more stable with less oscillation.
In such a centralized hydraulic system, a diesel engine drives variable hydraulic pumps as power sources, to provide high-pressure oil fluid. Then, the hydraulic energies are distributed and delivered to multiple hydraulic actuators (e.g. Hydraulic cylinders or motors) through the pipelines and control valves.
However, multiple hydraulic cylinders are still controlled by a traditional multi-way valve, leading to a substantial throttling loss. An independent metering control valve is a promising technology compared with the traditional multi-way valve.
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.
