摘要：【中文】本发明提供了一种局部圆弧织构化机械密封，包括动环和静环，所述动环和/或静环的密封端面均布若干微织构形貌。任一所述微织构形貌包括引流槽和圆弧沟槽，所述引流槽一端与密封介质连通，所述引流槽另一端指向动环或静环的圆心；两个所述引流槽之间连通若干圆弧沟槽。本发明提高了密封端面的流体介质润滑膜刚度，改善了流体动压润滑效应，圆弧织构可以存储润滑油并收集固体颗粒，减少了密封端面的磨粒磨损，减少工作过程过热的影响，提高了机械密封的使用寿命和运行稳定性。 【EN】The invention provides a local circular-arc textured mechanical seal which comprises a moving ring and a static ring, wherein a plurality of micro-texture appearances are uniformly distributed on the sealing end surface of the moving ring and/or the static ring. Any microtexture morphology comprises a drainage groove and an arc groove, wherein one end of the drainage groove is communicated with a sealing medium, and the other end of the drainage groove points to the circle center of the movable ring or the stationary ring; and a plurality of circular arc grooves are communicated between the two drainage grooves. The invention improves the rigidity of the fluid medium lubricating film of the sealing end surface, improves the hydrodynamic lubrication effect, can store lubricating oil and collect solid particles by the arc texture, reduces the abrasive wear of the sealing end surface, reduces the influence of overheating in the working process, and improves the service life and the operation stability of the mechanical seal.
