哈維微型蓄能器AC 40-1/4-60德國HAWE液壓油是一種不可壓縮的液體，因此無法利用液壓油來積累壓力能，必須依靠其他介質來轉換和積累壓力能。例如，利用氣體(氮氣)的可壓縮性研制的氣囊式充氣蓄能器，就是一種儲存液壓油的裝置。

　　哈維交流蓄能器壓力上升時，油進入蓄能器，氣體被壓縮，直至系統管路壓力不再上升；當管道壓力下降時，壓縮空氣膨脹，油被泵入回路，從而減緩管道壓力的下降。

　　Use:

　?、?When the load moves at a low speed, the required flow rate is less than that of the hydraulic pump, and the excess flow rate of the hydraulic pump is stored in the accumulator; when the required flow rate of the load is greater than that of the hydraulic pump, the liquid is released from the accumulator to make up for the shortage of the hydraulic pump flow rate.

　　(2) when the machine stops but still needs to maintain a certain pressure, the hydraulic pump can be stopped and the accumulator can compensate the leakage of the system to maintain the pressure of the system.
