How Accumulators Absorb Hydraulic Shocks

An accumulator is an important component in a hydraulic system that is used to absorb shocks and peak pressures in a hydraulic system. Hydraulic shocks in a hydraulic system usually occur due to sudden closure of valves, slow closure, or sudden stopping of other moving parts in the system.

Accumulators can store energy in a hydraulic system by isolating compressed gas or springs from the hydraulic fluid. When a hydraulic shock occurs in the system, the accumulator quickly releases the stored energy, thereby absorbing the shock and slowing down the rapid change in system pressure, protecting other components in the system.

Accumulators typically absorb hydraulic shocks in several ways:

1.Compressed gas accumulator: This type of accumulator uses a gas (usually nitrogen) isolated from the hydraulic fluid. When a shock occurs in the hydraulic system, the gas in the accumulator is compressed, which absorbs energy. When the system needs to release energy, the compressed gas pushes the hydraulic fluid back into the system, equalizing the pressure.

2.Spring Accumulator: This type of accumulator uses a spring to store energy. When a shock occurs in the system, the spring is compressed, absorbing energy. When the system needs to release energy, the spring pushes the hydraulic fluid back into the system.

The choice of accumulator depends on the specific application scenario and performance requirements. Whether using compressed gas or springs, accumulators are effective in absorbing hydraulic shocks and protecting other components in the hydraulic system from damage.
