【Abstract】 Based on dependence tests, the flow field in a scroll vacuum pump during operation was simulated and analyzed by means of the software ANSYS and programming by C++ language. The field distributions of both pressure within enclosed crescent compression chamber and velocity at exhaust outlet were therefore obtained for an operating scroll vacuum pump. The correlated results revealed that the analysis done can reflect basically the flow field distribution and its variation in an operating scroll vacuum pump, which will provide an efficient approach to the setting of various parameters in design and correlated influencing factors.更多还原
