Accumulators are metallic storage pressure vessels, that stores inert gas (mostly nitrogen) and compressed hydraulic fluid in it., with the two medias being separated internally by means of a flexible barrier.
What are accumulators?These vessels are filled-in initially by the system pump and it delivers the fluid to the system under pressure whenever needed.
Hydraulic accumulators play a crucial role in maintaining system efficiency and performance by storing and releasing hydraulic energy as needed. Different types of accumulators are available, each suited for various applications in industrial systems.
Areas of Accumulator applications, incl
- Volume compensation
- Energy storage
- Emergency fluid back up
- Energy recovery
- Safety functions
- Pulsations damping
- Shock absorption
- Vibrations dampening
- Flow stabilisation
- Media separation
Use of Accumulators benefits:
- To improve performance of the whole system
- Increase in service life of system
- Reduction in operating & maintenance costs
- Smoothens operation by reduction of pulsations
Accumulators are available with wide variety of
- Materials for specialized applications – carbon steel of many grades, stainless steel etc.
- Seal materials and configurations available.
- Plating – Nickel and chrome plating, and epoxy/anti-corrosive coatings available.
- Connections – from standard threaded and flange port connections to specialised flange connections.
- Position measurement (possible with piston accumulator only) – Proximity switches, linear transducers, or mechanical indicating rods available for identifying piston location.
