压力开关动作和从泵输送的加压油将呈红色进入累积，直到被充注的压力达到压力开关的最高限值。
Whenever a hydraulic line or system requires a pressurized oil, it can be automatically delivered from the accumulator, then the hydraulic equipment can keep the operation and the necessary pressure can be maintained within a certain pressure range required.
每当液压管路或系统需要加压油时，都可以自动从蓄能器输送，然后液压设备可以保持运行，并且可以将必要的压力保持在所需的一定压力范围内。
This means that the accumulator will supply a pressurized oil stored in its inside to the hydraulic line or system while the charge pressure changes from the highest to the lowest.
这意味着蓄能器将向液压管路或系统供应储存在其内部的加压油，同时增压压力从最高变为最低。
