The working principle of an accumulator

An accumulator is a device used in hydraulic systems to store and release hydraulic energy. Its working principle involves storing hydraulic fluid under pressure for later use. Here’s how it typically operates:

  1. Storage Phase: The accumulator starts in a charged state. During this phase, a hydraulic pump delivers fluid into one side of the accumulator, compressing the gas or displacing the separator (such as a piston or bladder) on the other side. As fluid enters, it compresses the gas or moves the separator, increasing the pressure within the accumulator. This pressurization stores potential energy in the form of pressurized hydraulic fluid.
  2. Energy Storage: The accumulator stores this potential energy until it’s needed. It acts as a reservoir of hydraulic energy that can be released quickly when demand arises.
  3. Discharge Phase: When there’s a demand for additional fluid or pressure within the hydraulic system, the accumulator discharges. This can occur automatically when system pressure drops below a certain threshold, triggering the release of pressurized fluid from the accumulator. Alternatively, it can be manually activated or controlled by system controls.
  4. Work Performance: The pressurized hydraulic fluid released from the accumulator is directed to the actuators, valves, or other components in the hydraulic system. It provides the necessary force or motion to perform the required work, such as moving cylinders, operating machinery, or controlling system functions.
  5. Recharging: After discharge, the accumulator needs to be recharged to restore its energy storage capacity. This is achieved by allowing fluid to enter the accumulator again, either passively through normal system operation or actively through a charging mechanism. The hydraulic pump compresses the gas or displaces the separator again, repressurizing the accumulator for future use.

In summary, accumulators play a critical role in hydraulic systems by providing supplementary hydraulic energy, absorbing shocks, maintaining pressure, and improving system efficiency and responsiveness.
