Experimental Study on the Performance of Bi-Directional Diamond Pores Textured End Seals

Published: 14 March 2022 Publication History

Abstract

Under given operating environment conditions, the influences of size, shape, arrangement and depth of diamond pores textured on friction torque, cavity temperature and end surfaces temperature were studied through experiment. The motion form of liquid membrane between the end faces and film-forming mechanism were further explored, and the textures form of good lubrication and sealing performances were gotten. The results show that the friction torque, cavity temperature and end faces temperature of the mechanical seal with bi-directional diamond pores all showed an increasing trend with the increase of pressure. With the increase of rotating speed, the cavity temperature and end faces temperature increased continuously, while the friction torque showed a trend of decreasing first and then increasing. At the same pressure or speed, the order of friction torque, cavity temperature and end faces temperature of the three textured end faces seals was as follows: 3#2#1#, therefore, the best tribological performance was the 3# specimen, the friction warming was the lowest. It followed that the mechanical seals with appropriate pores structure would produce excellent dynamic pressure, cavitation, interface slip effect and secondary oil storage function, which could effectively improve the performance and service life of the mechanical seal.
