Abstract
This study analyzed the internal flow structure of a small ejector and the major design factors that affect suction force. The ejector had a limited total length of 45 mm, and the primary nozzle had a diameter of 1 mm. This study investigated the effect of the main parameters on optimum nozzle opening ratio based on injection flow as well as the influence of the mixing chamber design on vacuum suction performance. The second nozzle had a significant effect when the diameter was 18 mm. Other parameter values were studied to identify design elements that determine the shape of the mixing chamber. The effect of the pad opening gap and the change in ambient pressure on the control state of the inflow ratio and the possibility of non-contact gripping were also examined.
