LECTURE 28 to 29 ACCUMULATORS FREQUENTLY ASKED
Accumulator as a hydraulic shock absorber One of the important applications of accumulator is the elimination of hydraulic shock. Hydraulic shock is caused by the sudden stoppage or declaration of a hydraulic fluid flowing at relatively high velocity in a pipe line. By rapidly closing a valve creates a compression wave.
How Hydraulic Accumulators Improve Efficiency in Hydraulic
Hydraulic accumulators help stabilize the pressure by absorbing shock loads and compensating for pressure drops, ensuring consistent operation. Shock Absorption:

6 FAQs about [Hydraulic shock absorber accumulator]
How do accumulators absorb flow shock?
To absorb flow shock, the accumulator is usually pre-charged at about 70 to 80% of system pressure. At this pre-charge pressure, only a small amount of fluid enters the accumulator subsequent to a shock situation. There is also little fluid transfer to take away from or add to the normal pump flow.
Can accumulators reduce damage from shock?
Accumulators can reduce damage from shock in some circuits if correctly applied. In other applications, an accumulator may add shock by releasing stored energy too quickly. The top half of Figure 1-28 illustrates one way shock is produced. Flow velocity in a hydraulic circuit may be 25 to 30 fps and not cause any problems.
Why are hydraulic accumulators important?
This helps in smoothing out the demand on the system, leading to more efficient energy use. Shock Absorption: Hydraulic accumulators are excellent for absorbing shock caused by sudden changes in hydraulic pressure.
Which accumulator should be used in a hydraulic system?
In modern, often mobile, hydraulic systems the preferred item is a gas charged accumulator, but simple systems may be spring-loaded. There may be more than one accumulator in a system. The exact type and placement of each may be a compromise [clarification needed] due to its effects and the costs of manufacture.
How do shock absorbers work?
Add valves between the accumulator and the cylinder to control the shock absorber after it finishes decelerating the load. Some large, slow-turning piston pumps send a shock wave into the circuit every time a piston discharges oil.
How does an accumulator work?
An accumulator absorbs excess pump flow with minimal pressure override or shock. While fluid from the pump compensates from full flow to no flow, as seen in Figure 1-19, it has a direct path to the accumulator.
