TASK 29-10-00-810-804
External Leakage found on Components of the Hydraulic System
1. Possible Causes
2. Job Set-up Information

A. Referenced Information

REFERENCE DESIGNATION
AMM 29-00-00-280-006  Check of the Green or Yellow Hydraulic System after Operation in a Possible Cavitation Condition of the Engine Pump
AMM 29-00-00-790-001  Check of the External Leaks of the Hydraulic Components

3. Fault Confirmation

A. Do a check of external leakage of the related component AMM TASK 29-00-00-790-001 .

NOTE: Do the check of the Green or Yellow hydraulic system after operation in a possible cavitation condition of the engine pump if the hydraulic engine pump of the related hydraulic system has operated for more than 5 minutes:
- with closed engine pump fire valves and/or
- with the RSVR LO LVL warning on the upper ECAM DU
AMM TASK 29-00-00-280-006 .

4. Fault Isolation

A. If the fault confirmation gives that the leakage is out of tolerance:

- repair or replace the component as necessary.
B. Do the check as given in Para. 3. A. to make sure that no leakage occurs.
随便找了一个不知道可以吗？

液压系统故障很多，请你参见FIM。
现举一例：ELEC 1电门在ON位时LOW PRESSUER灯亮，发动机次显示器上无压力指示。很显然，电动液压泵不工作，把ELEC 1电门放OFF位，此时你需要打开P6-1跳开关面板，在面板内部有SYS B ELEC HYD PUMP GRD FAULT RESET电门，按压该电门后再把ELEC 1电门放ON位，此时电动泵工作，说明SYS B ELEC HYD PUMP MOTOR线路有磨擦接地，使P6-4 内T 196 CT电流互感器感受到大于2~4AMP的电流。

关于液压油箱串油的方法以前我在“技术交流”板块里已讲的很清楚了，你可以去找一下，很实用的。
液压系统具体有什么问题可发上来，我们共同学习研究解答好吗。
