Guidelines for Understanding and Maintaining Hydraulic Accumulators
A hydraulic accumulator is used for one of two purposes: either to add volume to the system at a very fast rate or to absorb shock. Which function it will perform depends upon its pre-charge. If the accumulator is to be used to add volume to the system, its pre-charge must be somewhat below the maximum system pressure so oil can enter it.

Back to Basics: Accumulators
A hydraulic accumulator is a pressure vessel containing a membrane or piston that confines and compresses an inert gas (typically nitrogen). Hydraulic fluid is held on other side of the membrane. An accumulator in a hydraulic device stores hydraulic energy much like a car battery stores electrical energy.

Bladder Accumulators Standard design
Accumulators Standard design 1. DESCRIPTION 1.1. SB330/400/500/550/600, SB330H/SB330NFUNCTION Fluids are practically incompressible and cannot therefore store pressure energy. The compressibility of a gas is utilised in hydraulic accumulators for storing fluids. HYDAC bladder accumulators are based on this principle, using nitrogen as the
CHAPTER 16: Accumulators
Accumulators make it possible to store useable volumes of almost non-compressible hydraulic fluid under pressure. The symbols and simplified cutaway views in Figure 16-1 show several types of accumulators used in industrial applications.

Safety Blocks
Our accumulator safety block is a multi-functional valve placed between the hydraulic accumulator and the operating system. The safety block allows for isolation of the accumulator for maintenance or system testing, and will function as an emergency shut-off device or pressure relief valve to protect the hydraulic system from over-pressurization or system failure.

6 FAQs about [Hydraulic accumulator manual]
What is a hydraulic accumulator?
Hydro-pneumatic accumulators are the most widely used type of accumulator in industrial and mobile hydraulic systems. They use compressed gas to apply force to hydraulic fluid. Identical in their operating principle, Parker’s piston, bladder and diaphragm accumulators use different mechanisms to sepa-rate the gas from the fluid.
How to install hydraulic accumulators?
The installation must be carried out by qualified hydraulic personnel with the proper hydraulic system schematic. Carefully unpack the accumulators by removing them from their wooden crate or loosening the plastic strapping around the skid on a flat surface.
What gas should a hydraulic accumulator use?
Since hydraulic accumulators are pressure vessels, the installation, commissioning, disassembly, and maintenance should be performed by professionally trained and qualified personnel. Only use an inert gas like nitrogen for a pre-charging. Nitrogen that is 99.99 percent by volume is strongly recommended.
Why should you use HYDAC accumulators?
HYDAC Accumulators have played a key role in providing innovative solutions resulting in lowering operational costs and increasing hydraulic system performance in mobile, industrial and process applications. This application guidebook will serve as an overview and allow focus on helping solve customers’ problems.
How do you precharge a hydraulic accumulator?
Correct precharging involves accurately filling the gas side of an accumulator with a dry, inert gas such as nitrogen, before admitting fluid to the hydraulic side. It is important to precharge an accumulator to the correct specified pressure. Precharge pressure determines the volume of fluid retained in the accumulator at minimum system pressure.
What is a correct accumulator?
A correctly specified accumulator can: reduce shock effects in a system resulting from inertia or external mechanical forces maintain system pressure by compensating for pressure loss due to leakage provide a back-up supply of hydraulic energy to maintain a constant flow when system demand is greater than pump delivery.
