With the increasing requirements of the sealing industry and the development of the industry, the design and manufacturing technology of mechanical seals is one of the most important key objects in the field of fluid transmission and control. Besides，higher requirements of the development of mechanical seals was also put forward. In order to promote the development of mechanical seal technology, the paper briefly introduces the future development of mechanical seal from the perspective of solving the problems of mechanical seal.The main development trends of mechanical seals are point out, such as higher sealing performance under extreme working conditions, service life and stability under conventional working conditions. In view of controllable mechanical seal, combination of mechanical seal intelligence and seal will become the development trend of mechanical seal in the future.
