C. The oil drain port drains the oil from the APU oil tank.
洩油孔從APU的滑油箱將滑油洩出
The location of oil drain port is at the bottom of the APU oil tank.
洩油孔的位置在APU滑油箱的底部
The oil drain port has an oil pump screen, two packings, an adapter
assembly and slotted cover.
洩油孔包含一個濾網 兩個油封 一個轉接器總成跟一個開孔的cover
是說圖中我也沒看到濾網及另一個油封在哪
可能藏在adapter assembly裡吧XD
The adapter assembly and slotted cover increase the rate of oil drainage
from the APU oil tank and prevent accidental oil spillage during the oil
drainage procedure.
轉接器總成及開了孔的cover會增加APU滑油箱的排油速率
並防止在洩油過程中發生意外性的漏油
The oil filler cap is located on the top right side of the APU oil tank.
APU滑油箱的加油蓋在APU滑油箱的右上方
The APU oil Tank is full when the oil level is at the center of the
top sight glass.
如果油面達到上窺視孔的中間 APU滑油箱就滿了
用小畫家畫起來應該是像這樣
不太專業的翻譯
希望能幫到你 考試加油
