The interior circulating oil path of first pipeline 2 and the second pipeline 4 composition cabin, the temperature for being mainly used for lubricating oil in gear-box 1, which is less than, to be set
The case where definite value (such as 45 degree), the first pipeline 2 and third pipeline 5 form the outer circulation oil circuit of cabin, and third pipeline 5 is by heat dissipation
Device 6, when the temperature of the lubricating oil in gear-box 1 is higher than setting value, radiator 6 works, main to be realized by outer circulation to profit
The heat dissipation of lubricating oil, and then guarantee the normal work of gear-box.
But in certain extremely frigid zones when outer circulation circuit stops working, part third pipeline 5 is due to being exposed to cabin
Outside, the lubricating oil in third pipeline 5 can freeze, and cause outer circulation circuit oil pressure abnormal, machine group alarm shut down influence generated energy and
Availability.
