Abstract
This project has been carried on so that the performance of a mechanical seal can be developed. Many studies were carried out in the improvement of the seal. The new development of the mechanical seal was started from the packing gland. But the performance of the seal due to wear caused by thermal loading is still in investigation. Some of the studies were not state clearly about the material used and the temperature distributions caused by the friction. In this thesis, reproduce method was used. Different kinds of seals will posses different performance. Hence, a method which was used in the previous work on other seals was applied in this thesis's interested seal. A mechanical seal's modeling was created by using SolidWorks. A finite element study was carried out to investigate the mechanical seal. Interface temperature distributions were carried out by using the finite element simulation in Ansys Workbench software with difference parameters. These parameters were included interface's temperature distributions cause by thermal conductivities effect, effect of coefficient frictions changed and effect of rotational speeds changed. Some of the formulas were applied in the simulation such as heat flux generation at the interface of seal. Verification of results was obtained and it showed that three parameters such as coefficient friction, thermal conductivities and rotational speeds had to be considered before seal's operations. The behavior of the temperature distributions was obtained which is the temperature at interface was increased when the coefficient friction and rotational speed increased. The temperature was decreased when the value of thermal conductivity increased.
