What is the function of the diaphragm on an accumulator?

he diaphragm in an accumulator plays a pivotal role in its operation. This flexible membrane separates the stored fluid or gas from the surrounding environment, maintaining pressure stability within the accumulator.
The diaphragm's primary function is to expand and contract as the pressure inside the accumulator changes. When the accumulator is charged, the diaphragm contracts, storing energy efficiently. Conversely, during discharge, it expands, releasing the stored energy.
This flexibility not only enables the accumulator to function effectively but also prevents the stored media from contamination or degradation. Additionally, the diaphragm acts as a shock absorber, minimizing the impact of sudden pressure changes or vibrations on the accumulator's structure.
In essence, the diaphragm is the accumulator's guardian, maintaining pressure stability, preserving media integrity, and extending the accumulator's lifespan. Without it, the accumulator would be unable to perform its intended function effectively.
