베인형 진공 펌프의 유동 특성 해석 평가

Recently, the electric driven auxiliary vacuum pump is becoming widely used to assist braking performance of vehicle. In this paper, the performance of the vane type vacuum pump is analyzed by computational fluid dynamic method. The characteristic of the flow rate and pulsation of discharge pressure is predicted on the vacuum pump including an vane, rotor and cam ring. Also, the influence on the performance of the various design factors of discharge port has been investigated such as position size and number of hall.
