Accumulator Precharge Pressure

The pressure you precharge a hydraulic accumulator to depends on the system requirements. Generally, you should precharge the accumulator to a pressure between 10% and 25% of the maximum pressure of the system. For example, if the system maximum pressure is 1,500 psi (10,345 kPa), then the accumulator should be precharged to between 150 psi
