不知320客舱门助推气瓶的压力有多大？

手册里描述是分有没有执行SB25-1613的
** ON A/C ALL
PRE SB 25-1613 for A/C 851-852

The damper and emergency-operation cylinder, installed on the support arm, damps door movement during opening/closing especially under abnormal conditions (heavy wind loads). Damping is effected by hydraulic fluid which pass through a restrictor as the operating rod extends or retracts.
The damper and emergency-operation cylinder is also an emergency actuator and assists the opening of the door in emergency condition.
This is effected by a gas cylinder installed on the body of the damper and emergency-operation cylinder. The gas which operates the cylinder is released when the door upward movement causes the pivoting stop lever to actuate the gas release lever, if the escape slide release system is armed.
The damping function is automatic at the end of the door travel (door open). It is possible to close the door again after a complete emergency opening.

A320一般在门的助推作动筒（门上）附件有一个有温度对应压力的表，按那个表上的压力来勤务
比如温度是20摄氏度，压力应该在1740PSI左右
Slowly open the filling system valve. Fill to the pressure indicated on the chart for the ambient temperature.
NOTE: Make sure that the pressure is not more than the maximum pressure indicated on the label.

4楼的太详细啦

压力温度对照表贴在门上的

那天感受了下助推气瓶有压力和没压力的门开关，没觉得有压力的助推气瓶门开起来有多大感觉。

谢谢四楼的详细解释，不同温度，充不同气压，也与不同机型的客舱门大小有关

他厉害了

应该最大起得作用是阻尼作用吧

747~400门上的助推气瓶是在门在预备位时辅助推开客舱门的，正常开关门助推气瓶不做动，气瓶气压在3000psi

不错啊呵呵。

恩说的很对压力那么大啊我们这的空客都是1700左右要看温度对应表

3000？这么大？如果充气的话有这么大压力的气瓶吗？我们这的气瓶压力高氮也就2000多

辅助开舱门的。

可以用泵增压的

客舱门预位时开门会触发，协助人员将门推出去，拉出滑梯释放钢索。
