涡旋压缩机径向迷宫密封迷宫槽的优化研究
Research on the Optimization Labyrinth Groove of Scroll Compressor’ s the Radial Labyrinth
摘要
Abstract
Many kinds of the labyrinth groove structure for scroll compressor’ s straight radial sealing was presented.Two-di-mensional unstructured girdmodel of labyrinth groove was set up bymean of GAMBIT,the internal flow and leakage loss of laby-rinth groove was simulated by FLUENT,the smoke tracer’ s experiment device of labyrinth groove was built,the leakage flow state and leakage of gas leakage loss was analyzed through experimental verification.The result of shows that the leakage loss of theoret-ical analysis and Simulation calculation was consistented,with the increase of clearance and vortex,the leakage become large,with the increase of clearance, the influence of groove structure for leakage become small, the best sealing performance of double stepped groove in the 0.002mm clearance was got.The idea was broadened for optimization design of the scroll compressor laby-rinth seal.关键词
