Product Description:

Material:
Usually made of carbon steel and other materials, the accumulator possesses high strength and corrosion resistance, allowing it to endure the high pressure within the hydraulic system.

Structure:
Generally, it features a bladder type structure comprising an oil section and a gas section sealed by a gas sealing element. The oil surrounding the bladder connects to the oil circuit, while the compressible gas (typically nitrogen) is used to store and release energy.

Specifications:
Volvo accumulators are available in various specifications tailored to different application scenarios and system requirements, including diverse volume and working pressure ratings. Common volume specifications range from 0.075L to 3.5L, with working pressures reaching up to 33MPa.

Energy Storage and Release:
Within the hydraulic system, the accumulator functions to convert hydraulic energy into gas internal energy for storage once the system pressure increases, and release the energy thereafter when the system pressure decreases, thereby stabilizing the system pressure.

Absorption of Hydraulic Shock:
Effectively absorbs pressure shocks resulting from sudden directional valve reversals, abrupt actuator stops, and other causes in the hydraulic system. This helps safeguard instruments, components, and sealing devices, reducing vibration and noise.

Elimination of Pulsation:
For hydraulic systems utilizing piston pumps with few pistons, the accumulator can absorb pulsating pressure and flow energy generated by periodic pump flow changes to minimize pulsation and reduce potential damage to sensitive instruments and equipment.

Emergency Energy Source:
In special circumstances like engine shutdowns or hydraulic pump failures, the accumulator can function as an emergency energy source by supplying pressurized oil to the system. This enables safe lowering of working devices or other essential operations to ensure machine safety.
