Abstract

Abstract:

The microstructures between the relatively sliding friction pair surface-interface can reduce attrition and improve lubricity. Computational domain model of cross scale lubrication film with micro-holes and micro-grooves on static and move rings were established. The lubrication film structured grids were meshed by the software ICEM with unique block mapping technology. Then the Fluent was used for numerical simulation. Taking the working conditions of the seal as the starting point, combined with the size of the micro-modeling structure, the paper discusses the four factors: the film opening force, the leakage amount, the friction coefficient of the lubricating film and the wall shearing force. The results showed that under the same medium pressure and rotational speed, the coverage ratio of micro-holes have a greater impact on the performance of gas sealing, and the increase is 5% to 8%, the gas sealing performance can achieve the best level when the coverage ratio of micro-holes is 50%. After that, the density, depth and diameter of the friction pair interface of the model were changed according to this criterion. It was found that the density and diameter of the micro-hole could significantly improve the sealing performance by 7% to 8%. And the gas seal performance can reach the best level when the micro-hole density is 12.5%, the depth is 10 μm and the diameter is 400 μm.
