When the accumulator pressure drop s below a minimum pressure p 1 = 100 bar the pump charges the accumulator up to a maximum pressure p 2 = 150 bar. The charged accumulator supports the hydraulics of the tool clamp as long as the pressure drops below p 1 again. In this case the energy (volume) of one accumulator filling is sufficient

Release any pressure at the accumulator inlet. Most accumulators have a dump valve that can be opened to drain oil to the tank. Screw the charging rig onto the accumulator’s Schrader valve and turn the gas chuck handle clockwise to depress the pin. The current pre-charge can then be read on the charging rig.

Accumulators can increase efficiency, provide smoother, more reliable operation, and store emergency power in case of electrical failure. Accumulators usually are installed in hydraulic systems to store energy and to smooth out pulsations. Typically, a hydraulic system with an accumulator can use a smaller pump because the

Now if we tweak our requirements a little, we can gain more advantage. I want to hold my load at 2000 psi. If my accumulator charge pressure is still 2000 psi but I only apply 2500 psi of hydraulic fluid to the accumulator, I increase my discharge volume. To calculate this we will need to see what volume is available at each pressure.
