Hydraulic accumulators store pressurized hydraulic fluid and release it as needed to maintain steady pump flow and pressure, dampen vibrations and shocks, and compensate for leaks or thermal expansion in the system. They can also accommodate for lost pressure if the system's pump fails or there is fluid loss in the system. Diaphragm accumulators are designed for low-volume applications with relatively low flow rates. Bladder accumulators are used in hydraulic systems that have medium flow rates and experience pulsation and shocks. Piston accumulators store large volumes of hydraulic fluid and are used for applications with high flow rates. Hydraulic accumulator charging and gauging kits are used to charge and monitor the pressure in hydraulic accumulators. Hydraulic accumulator safety blocks include shut-off and discharge valves to separate the accumulator from the hydraulic system for maintenance or in an emergency.
