The invention relates to a vacuum mechanical seal mechanism, and belongs to the technical field of sealing devices special for vacuum and fluid delivery pumps. The vacuum mechanical seal mechanism comprises a transmission shaft, a pump body, a rotating ring and a static ring, the transmission shaft is installed in the pump body, the rotating ring is installed on the transmission shaft in a sleeving mode, and the rotating ring, the transmission shaft and the pump body are in seal connection; one end of the static ring faces the rotating ring, the other end of the static ring is fixed to the pump body through a ring base, and an oil storage groove is formed in the face, facing the rotating ring, of the static ring and is used for supplying seal oil to the contact face between the static ring and the rotating ring and dividing the static ring and the rotating ring into two annular seal faces with the oil storage groove as the interface. The vacuum mechanical seal mechanism is applied to a vacuum machine and has
