摘要: 以气动系统中最典型的回路为对象对系统内部结露进行研究,提出气动系统发生内部结露的机理,即当系统内的水分向系统末端移动的能力大于水分向系统外部排出的能力时,系统发生内部结露,反之则不发生。用凝结水滴的质量密度描述水分向系统末端移动的能力,用容积比来代表水分向系统外部排出的能力,确定了凝结水滴的质量密度和容积比平面上的内部结露分界线。对一气动系统的内部结露现象进行试验研究,验证了该方法的正确性。

Abstract: The internal condensation is investigated by taking single driving system as an example, and the mechanism of internal condensation is unveiled as follows:When the ability of moving condensed vapor toward the blind end is greater than the ability of moving it out of the system, internal condensation occurs; Otherwise, it does not occur. By using mass density to represent the formmer ability and volume ratio to represent the latter one, a dividing curve is obtained on the plot of mass density versus volume ratio. The experiment of the internal condensation in a pneuamtic system is carried out, the results are verified by the experiment.

Key words: Internal condensation, Judging methods, Mechanism, Pneuamtic system
