The function of an accumulator is to store pressurized oil in the hydraulic system and release it again when needed. Its main functions are manifested in the following aspects.(1) Accumulators are used as auxiliary power sources to store overpressure oil from hydraulic pumps in hydraulic systems that operate intermittently or achieve periodic action cycles. When the system needs it, it is released by the accumulator. This can reduce the rated flow rate of the hydraulic pump, thereby reducing the
