【摘要】 在气动设备的配气装置设计中确定的参数，往往难以与实际工况完全吻合。因此，需对设计出来的样机进行测试，绘出其有关性能曲线，将实际工作状态的参数与设计参数相比较，找出二者之间存在的差异和原因，然后依此对某些结构尺寸和部位进行调整和改进，使设计者的主观意图与客观实际统一起来。更多还原

【Abstract】 Generally the parameters, determined in the design of air distribution devicefor pneumatic equipment,are difficult.to conform with the practical operating conditionscompletely.Therefore, it is necessary to test the designed prototype,draw up its curvesrelatie to the performance,compare,the actural parameters of working state with the de-eign parametera,analyze the differences between the two kinds of parameters and seek thecause,then adjust and inodjfy some structure sizes and locations,so that the designer con-cepr is unified with the practice.更多还原
