Abstract
In order to verify the correction of the friction factor fractal model of the end faces for mechanical seals, some tests for mechanical seal were conducted on the self-designed mechanical seal testing device. Experimental sealed medium was 15°C water. A series of experimental data of friction factor were obtained under different spring pressures and sealed fluid pressures as well as at various rotating speeds. Compared the theoretical calculation data with those of experimental, the results show that the friction factor variation of theoretical was the same as those of experimental with the change of the working parameters, the relative error decreased with the increase of rotating speed and sealed fluid pressure, and the maximum relative error was less than 5.5% when the rotating speed reached the normal working speed of 2900 rpm.
