| Abstract: | This paper presents a new kind of conic mechanical seals. It is different from end face ones which are widely used in our country. It can satisfactorily solve the difficult sealing problem of viscous liquid which contains hard particles.It has been fitted on sand pumps in oil fields with good performance, long life, low leak and power loss. In addition, it can be easily fitted and repaired, and the spring pressure can be in adjusted running condition. |
