Analytical and Experimental Investigation of Laser-Textured Mechanical Seal Faces
TLDR
An analytical model is developed to predict the relation between the opening force and operating conditions in a mechanical seal with laser textured micro surface structure in the form of micropores.Abstract:
An analytical model is developed to predict the relation between the opening force and operating conditions in a mechanical seal with laser textured microsurface structure in the form of micropores The model is valid for any desired shape of the micropores An optimization is performed for spherical shape micropores evenly distributed on one of the mating rings face to maximize the opening force and fluid film stiffness Results of a parametric study are presented showing the effect of the main design parameters on the seal performance Some results of an experimental investigation with water-lubricated seal rings are also shown and compared with the theoretical model Presented as a Society of Tribologists and Lubrication Engineers paper at the ASME/STLE Tribology Conference in Toronto, Ontario, Canada, October 26–28, 1998read more

State of the Art in Laser Surface Texturing
TL;DR: Laser Surface Texturing (LST) is probably the most advanced surface texturing technique as mentioned in this paper and it produces a very large number of micro-dimples on the surface and each of these microdimples can serve either as a micro-hydrodynamic bearing in cases of full or mixed lubrication.

The effect of laser surface texturing on transitions in lubrication regimes during unidirectional sliding contact.
TL;DR: In this article, the impact of laser surface texturing on friction transition was investigated with a pin-on-disk apparatus at sliding speeds in the range of 0.015-0.75m/s and nominal contact pressures that ranged from 0.16 to 1.6m/a.

A Model for Mechanical Seals with Regular Microsurface Structure
Izhak Etsion,Leonid Burstein +1 more
TL;DR: In this paper, a mathematical model is developed to allow performance prediction of all-liquid noncontacting mechanical seals with regular micro-surface structure in the form of hemispherical pores, and an optimum pore size is found that depends on the other variables and corresponds to maximum axial stiffness and minimum friction torque.
