[0033] In the embodiment, the intelligent rolling oil steady-state device further comprises a first pipeline 510 and an oil return pipeline 520, the first pipeline 510 is provided with a working pump 511 and a three-way valve 512; wherein the input end of the three-way valve 512 is connected with the crude oil tank 30 through the working pump 511, the first output end of the three-way valve 512 is connected with the crude oil tank 20, and the second output end of the three-way valve 512 is connected with the crude oil tank 30 through the oil return pipeline 520.
