| Abstract: | The causes of frequent failure of mechanical seal of LPG pump were analyzed.The main cause of failure is that the sealing medium is easy to gasify and a dry friction is easy to form on the sealing surface. To deal with this problem,the rehabilitation programs on the use of tandem dry gas seal was proposed according to the dry gas seal's working principles and characteristics.The precautions in the installation and operation of tandem dry gas seal are presented. |
