Hydraulic Accumulators & Accessories: Function, Types & Applications
Hydraulic accumulators are essential devices in hydraulic systems that store energy and release it when needed. Their main function is to dampen pressure peaks and water hammer, protecting the system from damage and ensuring smoother operation.
How do hydraulic accumulators work?
Accumulators use the compressibility of a gas (usually nitrogen) or the elasticity of a spring to store energy. When the pressure in the hydraulic circuit increases, the accumulator charges, compressing the gas or spring. When the pressure decreases, the accumulator releases the stored energy, helping to maintain a constant pressure in the system.
Types of hydraulic accumulators
There are different types of hydraulic accumulators, each with specific characteristics suitable for different applications:
- Hydropneumatic accumulators: Use a gas (nitrogen) to store energy. They are the most common and versatile.
- Piston accumulators: Use a piston to separate the oil from the gas. They are suitable for high-pressure applications.
- Bladder accumulators: Use an elastic bladder to separate the oil from the gas. They are suitable for applications with volume variations.
Benefits of hydraulic accumulators
The use of hydraulic accumulators offers numerous advantages, including:
- Protection from pressure peaks and water hammer
- Improved system efficiency
- Increased component lifespan
- Ability to store energy for later use
