Abstract: The structure of mechanical seal of boiler feed pump in a thermal power plant in India and the arrangement of its sealing circulating liquid pipeline were introduced. The working principle of the mechanical seal and the influence of the higher temperature of mechanical sealing liquid on the sealing property were expounded. Combining with practical project, the reasons of the higher temperature of sealing liquid caused by its leakage were analyzed, and relevant solving measures were put forward.
