The mechanical sealing apparatus (300) includes a static ring (310), a sliding ring (320), a movable ring (330), and a drive structure (340). The sliding ring (320) is disposed inside the static ring (310) or is sleeved outside the static ring (310) in a radial direction of the static ring (310), the sliding ring (320) and the static ring (310) are fastened in a circumferential direction of the static ring (310) and can move relative to each other in an axial direction of the static ring (310), and hardnesses of the static ring (310) and the sliding ring (320) are different. The movable ring (330) is disposed at one end of both of the static ring (310) and the sliding ring (320) in the axial direction. The drive structure (340) is configured to drive the sliding ring (320) to move toward the movable ring (330) in the axial direction. Through disposing of the sliding ring, different sealing surfaces may be formed between the movable ring and both of the sliding ring and the static ring that have different hardnesses, so that the mechanical sealing apparatus, the fluid mechanical device, and the mechanical sealing method are applicable to different fluid environments and improve sealing effect.

摘要： Provided is a slide component that can prevent deposit formation on a sealing face as well as promoting circulation of a fluid on sealing faces while fulfilling both conflicting conditions of sealing and lubrication, to maintain the sealing function of the sealing faces for a long period of time. One slide part 5 is provided, on a low-pressure side of a sealing face thereof, with a negative pressure generation mechanism 10 including a negative pressure generation groove 10. The negative pressure generation groove 10a communicates with a high-pressure fluid side and is separated from a low-pressure fluid side by a land portion R. The other slide part 1 is provided, in a sealing face thereof, with at least one interference groove 15 communicating with the high-pressure fluid side for producing pressure variations in a fluid in the negative pressure generation groove 10a. The at least one interference groove 15 has an end 15a on an inside-diameter side extending to a position to radially overlap the negative pressure generation groove 10a.
