メカニカルシールの防塵装置。[Claims for Utility Model Registration] (1) A seat ring fitted into a hole in a housing, a rotating shaft passing through this seat ring, and a driven ring provided on this rotating shaft and slidingly contacting the seat ring, In a mechanical seal comprising a pulley fixed to the rotating shaft and rotating together with the rotating shaft, the pulley is integrally formed with a cylindrical part that is loosely fitted into a hole in the housing, and the surface of the cylindrical part is A dustproof device for a mechanical seal, characterized in that the dustproof device is arranged close to at least either the inner peripheral surface of a hole in a housing or the surface of a seat ring. (2) The outer circumferential surface of the cylindrical portion of the pulley is close to the inner circumferential surface of the hole in the housing, and the rotation of the cylindrical portion causes the atmosphere to flow between the seat ring and the driven ring. A dustproof device for a mechanical seal according to claim 1, characterized in that a spiral groove is formed to guide the mechanical seal away from the sliding surface. (3) The outer circumferential surface of the cylindrical portion of the pulley is close to the inner circumferential surface of the seat ring, and the rotation of the cylindrical portion allows air to flow between the seat ring and the driven ring. A dustproof device for a mechanical seal according to claim 1 or 2, characterized in that a spiral groove is formed to guide the mechanical seal away from the sliding surface of the mechanical seal.
