Abstract
There is provided a sliding component that supplies a sealed fluid to a leakage side in a gap between sliding surfaces to exhibit high lubricity and has a small leakage of the sealed fluid. A sliding component that has an annular shape and is disposed in a place where relative rotation is performed in a rotary machine, includes a plurality of dynamic pressure generating mechanisms provided in a sliding surface of the sliding component, each of the dynamic pressure generating mechanisms including a deep groove portion that communicates with a leakage side, and a plurality of shallow groove portions that communicate with the deep groove portion and are arranged in a circumferential direction in parallel relationship to each other.
Claims (20)
1 . A rotary machine comprising a housing, a rotating shaft configured to rotate with respect to the housing and a mechanical seal disposed between the housing and the rotating shaft, wherein
the mechanical seal includes a first sliding component having a sliding surface and a second sliding component having a sliding surface which faces to the sliding surface of the first sliding surface,
the rotary machine further comprises a biasing member configured to bias the first sliding component toward the second sliding component,
a sliding surface of at least one of the first sliding component and the second sliding component is provided with a plurality of dynamic pressure generating mechanisms each including a deep groove portion that communicates with a leakage side, and a plurality of shallow groove portions that is shallower than the deep groove portion, at least a part of the shallow groove portions communicating with the deep groove portion and being arranged in a circumferential direction in parallel relationship to each other,
each of the dynamic pressure generating mechanisms further includes at least one sub-shallow groove portion that directly communicates with the leakage side, that is arranged on the leakage side of the shallow groove portions, and that is independent of the shallow groove portions,
the deep groove portion has a depth which is five times or more depths of the shallow groove portion and the sub-shallow groove portion,
the shallow groove portions and the sub shallow groove portions are arranged within an imaginary band-shaped region which has a constant radial width and extends in a circumferential direction in concentrical relationship with the mechanical seal,
part of the sub shallow groove portions extends up to an edge line of the imaginary band-shaped region extending in the circumferential direction on a sealed fluid side,
at least one of the shallow groove portion and the sub shallow groove portion is formed in an arc shape in a plan view, and
the arc shape is a shape in which an imaginary straight line connecting both ends of the arc is positioned on the sealed fluid side with respect to the arc.
2 . The rotary machine according to claim 1 ,
wherein the shallow groove portions extend from both sides of the deep groove portion in the circumferential direction.
3 . The rotary machine according to claim 1 ,
wherein the deep groove portion communicates with an inner diameter side.
4 . The rotary machine according to claim 2 ,
wherein the deep groove portion communicates with an inner diameter side.
5 . The rotary machine according to claim 1 ,
wherein the shallow groove portions extend toward a sealed fluid side.
6 . The rotary machine according to claim 1 ,
wherein the shallow groove portions toward the leakage side are curved in the circumferential direction.
