Estimating the term…
A single or multiple stage mechanical seal assembly in which one seal ring is resiliently coupled to a rotatable shaft and the other seal ring is resiliently urged toward the first seal ring by axially-arranged identical springs received in spring pockets in a spring retainer, some pockets opening at one radial surface of the retainer and others opening at the other radial surface of the retainer. The outer surfaces of the seal rings are protected against deflection by being encircled by cylindrical members and one seal ring is resiliently coupled to its encircling cylindrical member. A balance sleeve means partly supports the axially movable seal ring and is capable of angular adjustment to compensate for shaft misalignment.
A mechanical seal assembly for separating a high pressure fluid and a lower pressure fluid, and associated with a rotatable shaft and a stationary housing, said assembly comprising:
A mechanical seal assembly for use with a pump shaft subject to axial and radial deflections and for substantially preventing the flow of fluid along at least a portion of said shaft, said assembly comprising the combination of a pair of relatively rotatable seal rings, each having a seal face which oppose one another, a series of circularly arranged springs defining first and second spring sets which combine to resiliently urge one seal ring axially toward the other to maintain their seal faces in a closely opposing relationship, the springs defining the first spring set being mounted such that their ends engage surfaces which are axially spaced from those surfaces engaged by the ends of the springs defining the second spring set, a sleeve means surrounding and spaced from said shaft supporting said one seal ring, and resilient sealing means interposed between said one seal ring and said sleeve means permitting limited axial movement of said one seal ring relative to said sleeve means.
A self-compensating mechanical seal assembly for separating a high pressure fluid and a lower pressure fluid, and associated with a rotatable shaft and a stationary housing, said assembly comprising:
