Customer ServiceIf a volume of fluid is confined and unable to expand or contract due to temperature changes, there could be very high pressure that could damage equipment or low pressure that could cause air bubbles in the hydraulic fluid. Accumulators can be used to absorb the expanding fluid and/or supply the contracting fluid. They also absorb and
Customer ServiceAccumulators Low pressure 1. DESCRIPTION 1.1. HYDAC low pressure bladder FUNCTION 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 compressible medium.
Customer ServiceParker EBV bladder accumulators are suitable for low pressure fluid systems, and are ideally suited for the energy, process and marine markets. They are available in volumes from 0.5 to 575 litres in carbon steel (20 to 80 bar), and in stainless steel (20 to 40 bar).
Customer ServiceWhen required, the accumulator pushes fluid into the hydraulic circuit to add to the pump flow. When the actuators in the hydraulic system are not in motion, the accumulator will refill. Accumulators can also operate as energy sources during normal operation of the system. Accumulators that are weight- or spring-loaded can also be used in industrial applications.

Customer ServiceA hydraulic accumulator is a pressure storage reservoir that stores hydraulic fluid under pressure, often using compressed gas. Key components include the shell, bladder/diaphragm, and gas pre-charge. Accumulators store energy in the form of hydraulic fluid, releasing it when needed to maintain pressure or deliver additional power to the system.
