摘要
根据螺杆式压缩机滑阀容量调节的特点,建立螺杆式压缩机部分负荷性能计算模型,并用螺杆式压缩机性能的实测数据对模型的预测精度进行验证。结果显示:模型预测的螺杆式压缩机部分负荷性能与实测数据吻合,在测试数据范围内,模型预测的最大误差小于2%。
According to the characteristics of capacity regulating for screw compressor with slide valve,sets up the part load performance calculation model for screw compressor.Validates its prediction precision compared with the test data.The results show that the predictive value is consistent with the test data,and the maximal error is less than 2%.
