【 摘 要 】
In order to reduce the leakage of the axial clearance, the sealing strip is mounted at the top of the scroll tooth. For achieving the axial displacement compensation seal, it is put forward to open a hole that it is in one side of the high pressure chamber at the bottom of sealing groove. The high pressure chamber gas is introduced into the bottom of the seal. It can form a pressure difference. The article begins with the design of sealing groove structure. The stress analysis was carried out on the sealing strip, and sealing strip was established displacement calculation model of change. Secondly, through the simulation experiment, the friction and wear properties of several kinds of seal materials are compared and analysed. To select PEEK as sealing strip material is the most appropriate. Finally, taking typical parameters of involute scroll compressor as an example, the compressive performance of scroll teeth with sealed structure and non-sealed structure is simulated. The results show that the sealing displacement and axial clearance are basically the same under the two schemes. The sealing scheme is proved to be feasible. This lays the foundation for the further study of the axial seal of the variable section scroll compressor.【 预 览 】
