High-pressure hydraulically controlled system with a piston accumulator for the inlet valve

Stepwise Heating Furnace Thermal Energy Storage Electro-Hydraulic Energy-Saving System

In response to the operating conditions of the walking beam, such as its work cycle, an accumulator‑based system is employed to replace the oil pump‑motor unit as the primary power source for lifting and other motions of the heating furnace’s walking beam. This upgrade transforms the system into an energy‑saving hydraulically controlled system with potential‑energy recovery capability, significantly reducing the installed capacity and enabling recovery of potential energy during the descent phase. Furthermore, by appropriately upgrading and modifying the hydraulic control valve assemblies, hydraulic balance within the walking‑beam hydraulic system is achieved, providing a stable balancing force for the furnace’s walking beam and compensating for the weight of both the beam and the steel billets. As a result, the installed power of the hydraulic system is substantially reduced, while overall system operation becomes more balanced.

Hydraulic Control System for the Power Source of the Blast Furnace Accumulator

Piston accumulators equipped with energy‑monitoring systems from Xiwel are widely used in the hydraulic control systems of blast furnaces. These hydraulic control systems serve as the core power and control hub for blast furnace machinery, providing high‑pressure, stable hydraulic power to support top‑of‑furnace charging, front‑of‑furnace iron tapping operations—such as mud guns, taphole openers, and slag skimmers—and valve switching, thereby ensuring safe, continuous, and efficient blast furnace operation.

Adopting an accumulator‑based power source with reliable energy monitoring: building a green, energy‑saving pathway.

In many industrial applications, instantaneous high flow rates are required as the driving power source—for example, in metal forming, electro-hydraulic systems for walking-beam furnaces, converter shrouds, and the opening of valves and circuit breakers. If conventional oil pump‑motor units were used as the actuation power source,

What are the causes of severe pressure drop and shortened service life in bladder-type accumulators?

What are the causes of severe pressure drop and short service life in bladder-type accumulators? The structure of a bladder-type accumulator is quite simple, consisting mainly of an oil chamber surrounding the bladder and a gas chamber equipped with a gas‑tight seal. During operation, the hydraulic fluid must be connected to the hydraulic circuit; when the system pressure rises, the fluid flows into the accumulator, compressing the gas until the pressure in the system pipeline stabilizes.

How can we reduce failures when an accumulator malfunctions?

If an accumulator malfunctions, its performance will be directly affected, potentially leading to abnormal pressures and system failure. Therefore, it should receive close attention during routine operation, and appropriate measures must be implemented to mitigate risks. So, how can we minimize failures when an accumulator malfunctions? The following sections address this issue.
