| Abstract: | The original surface morphology and the worn surface morphology of static ring end-face of mechanical seal was analyzed by metallographic microscope. The wear form and the differences between inner diameter and outer diameter were obtained. The contact stress and temperature field distribution on the seal end-face are analyzed by means of simulation. The influences of rotating speed, medium pressure and other conditions on end-face contact stress and temperature field are also analyzed by means of ANSYS software platform. The effect of end-face contact stress and temperature variation on the properties of wear was verified. The wear mechanism of mechanical seal was expounded. |
