液压系统1和2液压油使用位于后设备舱的单个空气/液压热交换器冷却。 以下适用于所描述的系统的是:Hydraulic systems 1and 2 hydraulic fluids are cooled using a single air/hydraulic fluid heat exchanger which is located in the aft equipment bay. The following applies to the described system.
A. 尽管系统1和2共享同一套热交换器,但两套系统之间没有液压油混合。Although systems 1 and 2 share the heat exchanger there is no mixing of hydraulic fluid of the two systems.
B. 由于只有一个热交换器,两个系统都必须被增压以防止两个系统之间的液压油混合。Since there is only one heat exchanger both systems must be pressurized to prevent mixing of hydraulic fluid between the two systems.
C. 在地面上必须避免使用液压系统1和2,因为液压滑油冷却不充分,而与外部空气温度无关。On ground use of hydraulic system 1 and 2 must be avoided because of insufficient cooling of hydraulic oil, independent of the outside air temperature.
D. 在启动期间的极低温度(10℃和更低)下,热交换器冷却空气旁通热交换器。At very low temperatures (10C and lower) during start-up the heat exchanger cooling air is by- passed around the heat exchanger.
