A model of letting out of no oil ubricated double whirlpools vortex air compressor was set up,The length of leak line of one cycle was calculated the change of the leak line at work,The change of the length of leak line varying with the crank corner,and the change of the leak amount varying with the pressure of revealing atmospheric and crank corner were analyzed.
建立了无油润滑双涡圈涡旋压缩机的泄露模型,根据型线的几何理论计算了一个周期内泄漏线的长度,分析了在工作过程中泄漏线的变化,泄漏线长度随曲柄转角的变化,以及泄露量随排气压力,曲柄转角的变化情况。

The main components of the double-eddy-generator vortex flowmeter are two eddy- generators placed sequentially in the flow direction.
双涡体涡街流量计，是将两个涡发生体沿来流方向顺序排列在流量计壳体中，迎流第一个涡发生体用来产生强烈的旋涡，其后第二个涡发生体与第一个涡发生体之间产生流体相互作用，达到增强、稳定旋涡的目的，并提供有效的检测方式和手段，同时使用压力传感器、温度传感器和ＭＣＳ－８０９８单片机，对流体的密度因压力、温度变化而引起的测量误差进行自动补偿，从而提高了测量的准确度和重复性。
