How does a pressure accumulator work
WebThe function of an accumulator is to: Dampen pressure surges in the hydraulic system caused by actuation of a unit and the effort of the pump to maintain pressure at a preset level. Aid or supplement the power pump when several units are operating at once by supplying extra power from its accumulated, or stored, power. WebMay 23, 2024 · When the valve is closed thermal expansion of the oil in the unit will result in a build up of pressure inside your Accusump. Since air is highly compressible, if you have an adequate pre-charge of air in the Accusump it will likely accommodate this expansion without too much added pressure.
