摘要
建立一种基于实验数据的螺杆式压缩机容积效率计算模型,该模型可以在很宽的运行工况范围内较准确地预测螺杆式压缩机的容积效率,在回归数据范围内,预测最大误差小于1%。
The calculation model for volumetric efficiency of screw compressor is devel- oped. The model can predict the volumetric efficiency in a wide running scope with satis- factory precision. Compared with tested data,the maximal error is less than 1% in range of regression data.
