上图所示为漏风口质量流量以及出口质量流量随抽风负压大小变化情况,从图中可知,漏风口质量流量以及出口质量流量随抽风负压大小增大而增大,但出口质量流量增大速度高于漏风口质量流量增大速度。
The above figure shows the change of air leakage port mass flow and outlet mass flow with the suction negative pressure. From the figure, it can be seen that the air leakage mass flow and outlet mass flow increase with the increase of suction pressure, but the outlet mass flow increases. The high speed is higher than the increase speed of the mass flow at the air leakage opening.
