6 Frequently Asked Questions about “Monaco Micro Hydraulic System Accumulator”
What is a diaphragm accumulator?
A freely moving piston separates the compressible gas cushion from the hydraulic fluid. The diaphragm accumulator type AC is used as a source of pressurized oil. It supports or increases the pump delivery flow or stores pressure energy, e.g. for an accumulator charge circuit. The type AC is available as a miniature hydraulic accumulator.
What are hydraulic miniature accumulators used for?
The hydraulic miniature accumulators with a capacity of 0.013 dm³ and 0.040 dm³ are used for applications including clamping hydraulics for volume compensation in the event of temperature fluctuations, covering possible oil losses due to leakage or oscillation damping of functional parts activated by pressure difference.
Why do hydraulic accumulators work?
When kept under constant pressure, they allow the hydraulic system to operate instantly as needed, without the delays or pulsing that would usually be generated by using a pump alone. The smoother process created by the accumulator increases the lifespan of a hydraulic system as it is less demanding for valves, seals and other components.
