无油润滑双涡圈涡旋空压机的泄漏研究

Research of Leak of No Oil Lubricated Double Whirlpools Scroll Air Compressor

建立了无油润滑双涡圈涡旋压缩机的泄漏模型,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,以及泄漏量随排气压力、曲柄转角的变化情况。

Sets up a model of no oil lubricated double whirlpools scroll air compressor,calculates the length of leak line of one cycle according to geometric theory of profile, analyzes the change of the leak line at work, the change of the leak line length varying with the crank comer,and the change of the leak amount varying with the discharge pressure and the crank comer.
