在每次检测或调整蓄能器压力之前，请将蓄能器与系统断开并将液体放空。

Before each test or adjustment of accumulator pressure, please disconnect the accumulator from the system and vent the liquid.

充气时，氮气瓶中的压力必须足够高，以满足充气要求，否则，需要有充氮小车。

During inflation, the pressure in the nitrogen cylinder must be high enough to meet the inflation requirements, otherwise, a nitrogen charging trolley is required.

要遵守相应的安全法规，必须使用纯度大于99.8%的氮气。

To comply with the corresponding safety regulations, nitrogen with purity greater than 99.8% must be used.

阀体上的M28X1.5内螺纹是用来为隔膜式蓄能器充气的，为皮囊式或者活塞式蓄能器充气时，只要在阀体内螺纹处上连接对应的充气接头即可。

M28x1 on valve body 5 the internal thread is used to inflate the diaphragm accumulator. When inflating the bladder or piston accumulator, just connect the corresponding inflation joint on the internal thread of the valve body.

将充气接头拧到蓄能器充气阀上，同时保证卸压阀关闭，逆时针旋转芯轴的内六角螺丝来开启气阀。

Screw the charging connector onto the charging valve of the accumulator and ensure that the pressure relief valve is closed. Turn the hexagon socket screw of the mandrel counterclockwise to open the gas valve.

打开卸压阀，把充氮工具内氮气放尽。

Open the pressure relief valve and drain the nitrogen in the nitrogen charging tool.

还有需要注意的是严禁将氧气或者空气充入蓄能器中。

It should also be noted that it is strictly prohibited to charge oxygen or air into the accumulator.
