Hydraulic accumulators would be like large flywheels but for machines that used hydraulic instead of electric power. They hold energy so that their machines can run without friction.
As the hydraulic system pumps fluid into the accumulator, it squashes the gas inside. This maneuver reserves energy for when the system needs a bit of a boost.
There are two sections inside of a hydraulic accumulator that are separated by a component known as a piston. One of its two sides contains gas, while the other holds hydraulic fluid. When the system requires more energy, the piston shifts and water and gas is released to help drive the machine.
The accumulator gives up its stored energy to aid the hydraulic system during heavy work. This is useful for the machine to operate in heavy loads or abrupt variations without the motor slowing down.
Think, for instance, of a balloon that has been blown up with air. When you compress the balloon, the air inside is compressed. That’s the idea of the hydraulic accumulator, which stores energy in the form of compressed gas, which can then be used to run the machine whenever necessary.
