Working principle of high pressure pump accumulator

When the hydraulic pump forces fluid into the accumulator, the fluid compresses the nitrogen gas, reducing its volume and increasing its pressure, thereby storing energy. When system pressure drops, the compressed gas expands, pushing the stored fluid back into the hydraulic. Hydraulic accumulators store hydraulic fluid under pressure to supplement pump flow and reduce pump capacity requirements, maintain pressure and minimize pressure. Accumulators come in a variety of forms and have important functions in many hydraulic circuits. They serve as crucial components in various industrial systems, providing energy storage, shock absorption, and pressure regulation capabilities. Their operating principle is based on the Boyle-Mariotte‘s law (P x V = constant) and the compressibility difference between fluids and gases.
