The development characteristics of mechanical seals are as follows:

①Continuous innovation in mechanical seal theory, technology and products. New technologies, new concepts, new structures, new materials, new processes and new standards are constantly emerging; high parameters (such as high pressure, high speed, high temperature, large diameter), high performance (such as dry running, zero leakage, zero escape, no oil Lubrication, sealing slurries) and high-level sealing products (such as sulphur value, large split type, condition monitoring) have been developed in large quantities; failure mechanisms (such as blisters, thermal cracks, cavitation-cavitation, rubber seal swelling and aging) ), failure analysis (frequent opening and shutting leakage problems, cavitation wear failure, failure reliability analysis, seal failure) and failure monitoring (such as fluid film, friction state and phase state) research and application.

②The sealing technology is transformed from empirical design to theoretical expert system design. Empirical design or value) is a traditional design method. Based on empirical knowledge, the geometric parameters and spring specific pressure of the seal are determined, and the contact torque, linear velocity, frictional power consumption, frictional heat, and flushing volume of the seal end face are sequentially calculated. And determine the corresponding auxiliary system; computer-aided design is mainly limited to the drawing of sealing parts. The theoretical expert system design (p-v-T-h-t) uses computers as tools,

According to the specific process conditions, the perfect professional database and professional software are used to carry out performance analysis, dynamic simulation, structural optimization, and parameterized design of the seal, so as to maximize the practical performance of the seal in the design stage and realize the design It is reasonable, accurate, fast and efficient to meet the needs of specialization and large-scale production of sealing.
