摘要
A hydrostatic mechanical seal assembly includes a locally deployed pump for pressurizing a lubricant fluid between the opposing faces of a mating ring and a sealing ring. In one exemplary embodiment, such pressurization may be achieved via a device that converts the rotational motion of a drive shaft into fluid pressure. The locally deployed pump is intended to advantageously provide a stable positive pressure on the sealing interface between the mating and sealing rings, which may provide improved sealing characteristics, especially in demanding downhole environments.
