Embodiments of the present embodiment will be described below with reference to the drawings.
As shown in fig. 1, the pressure execution oil supply module 400 and the lubrication and cooling oil supply module 200 have the same composition, and the pressure execution control module 300 and the lubrication and cooling control module 100 have the same composition, and the operation principle of the pressure execution oil supply module 400 and the lubrication and cooling control module 100 will be mainly described below by taking the lubrication and cooling oil supply module 200 and the lubrication and cooling control module 100 as examples.
As shown in fig. 2, the lubricating and cooling oil supply module 200 is composed of an oil suction filter 5, a gear oil pump 6, a check valve 7, a coupling 8, a motor 9, a first filter 10, a second filter 11, an electromagnetic overflow valve 12 and a connecting pipeline.

Meanwhile, the fixed part of the pipeline is connected by a hard pipe, so that the stability is good; when the clutch coupling type motor is connected, the clutch coupling type motor is connected through a hose, so that the clutch coupling type motor is easier to disassemble.
