Abstract:
1. A mechanical seal assembly, comprising: a stationary seal ring connected to a stationary component; a rotating seal ring connected to a rotating component, wherein the stationary and rotating seal rings are engaged together to seal between a high pressure region and a low pressure region; a divided power absorption ring arranged at the rotating component, wherein the divided power absorption ring is divided in a radial direction into two circumferential half-ring parts; and a compensation ring unit comprising a first ring, a second ring and a third ring, wherein the first ring and the second ring have a higher strength than the third ring, and wherein the compensation ring unit is arranged in a force path defined between the high pressure region and the divided power absorption ring, wherein the first ring comprises a first step and the second ring comprises a second step and the third ring is arranged in an axial direction between the first step and the second step, wherein the inner diameter of the divided power absorption ring is smaller than that of the first, second, and third rings for seating of the divided power absorption ring in a groove of the rotating component to absorb axial forces transmitted from the high pressure region to the divided power absorption ring.
