A Piston Accumulator is a compression device that stores fluid during a vehicle's engine operation. It's essential to use the correct precharge pressure for the accumulator. The correct precharge pressure is at least 80% below the hydraulic system's minimum operating pressure. The precharge pressure determines the amount of fluid that will be stored in the accumulator at minimum system pressure. Incorrect precharge pressure can cause the accumulator to fail prematurely.
Piston accumulators are available in different sizes and lengths. Some are customized, while others are offered in only one size per capacity. They can operate under a wide range of temperature conditions. They are also available in a variety of materials. When considering a Piston Accumulator, make sure to consider the design and size of the application you're considering.
Piston accumulators are typically used in hydraulic systems. They store energy to augment pump flow and system response and backup during periods of power outages. They also reduce the amount of heat generated in the system. They can also reduce oscillations, pulsations, and concussion.
Hydraulic accumulators are usually pre-charged with dry nitrogen. This gas is the least expensive of the inert gases, and does not react unfavorably with hydraulic oil under pressure. Nitrogen composes almost 78 percent of the earth's atmosphere. In comparison, argon makes up less than one percent of the atmosphere.
