Novel vacuum pump with high vacuum degree

The utility model relates to the field of vacuum equipment, in particular to a novel vacuum pump with high vacuum degree. A novel high-vacuum-degree vacuum pump comprises a vacuum pump all-in-one machine, an oil gas barrel is installed on one side of the vacuum pump all-in-one machine, a partition assembly is installed on the other side of the vacuum pump all-in-one machine, a supporting partition plate is arranged in the partition assembly, a heat insulation plate is installed on the supporting partition plate, and a cooling mechanism is connected to the front portion of the heat insulation plate. An air guide cover is arranged in the cooling mechanism, a cooler is fixedly embedded in the air guide cover, and a fan is installed below the cooler. The vacuum pump is divided into a cold area and a hot area under the cooperation of the partition assembly, meanwhile, in order to prevent the lubricating oil from being thick, oil is guided into the cooler to be cooled under the cooperation of the oil pump and the t
