摘要(Abstract):

为定量研究变截面无油涡旋压缩机轴向间隙泄漏,基于等熵层流流动理论,建立了变截面涡旋压缩机在任意主轴转角时轴向间隙泄漏量的计算模型。通过求解该模型,分析了泄漏量与泄漏线长度、涡旋齿齿厚、工作腔容积、腔体温度之间的数值关系,得出基圆半径、轴向间隙对泄漏量影响的变化规律。为了验证计算模型的准确性,利用FLUENT软件对涡旋压缩机的工作过程进行仿真模拟,得出泄漏气体的速度、密度,并计算出轴向间隙平均泄漏流量,将模拟结果和理论计算结果进行了对比。结果表明:2种方法所得到的泄漏量变化趋势基本一致,该研究为新型线涡旋压缩机涡旋盘的加工、装配和密封提供理论参考提供理论参考。
In order to quantitatively study the axial clearance leakage of oil-free scroll compressor with variable section,based on the isentropic laminar flow theory,the calculation model of axial clearance leakage of scroll compressor with variable section at any spindle angle was established.By solving the model,the numerical relations between the leakage amount and the length of the leakage line,the tooth thickness of the scroll teeth,the volume of the working cavity and the temperature of the cavity were analyzed,and the variation law of the influence of the radius of the base circle and the axial clearance on the leakage amount was obtained.In order to verify the accuracy of the calculation model,FLUENT software was used to simulate the working process of scroll compressor to obtain the velocity and density of the leaking gas,and calculate the average leakage flow of axial clearance.The simulation results were compared with the theoretical results.The results show that the variation trends of leakage quantity obtained by the two methods were basically the same,and present study provides a theoretical reference for the processing,assembly and sealing of scroll member of the new linear scroll compressor.
