Energy storage lubricating oil system

The invention relates to the field of lubricating oil, and provides an energy storage lubricating oil system which comprises a lubricating oil tank and a fluid conveying pressurization assembly. An oil return cabin and an oil outlet cabin which are isolated from each other are arranged in the lubricating oil tank, an oil return opening is formed in the top of the oil return cabin, and an oil outlet is formed in the bottom of the oil outlet cabin; the oil return cabin is connected with the oil outlet cabin through the fluid conveying and pressurizing assembly, and the fluid conveying and pressurizing assembly is used for adjusting normal-pressure lubricating oil in the oil return cabin into high-pressure lubricating oil, conveying the high-pressure lubricating oil to the oil outlet cabin and compressing gas in the oil outlet cabin. Low-pressure lubricating oil in the oil return cabin is converted into high-pressure lubricating oil after being pressurized by the fluid conveying and pressurizing assembly, and th
