EXPERIMENTAL ANALYSIS AND SIMPLIFIED MODELING OF PRESSURE AND POWER IN ROTARY VANE AIR COMPRESSORS

对滑片式空气压缩机工作时的压力状态和功率组成进行分析研究,并通过与应用压力温度传感器和电流表的检测方法得到的试验数据进行比较来验证研究结果。在理论分析中,压力平衡状态被分成6个主要部分,功率组成分成4个主要部分,对每部分的压力和功率过程进行分析,建立理论计算模型,分别求解得到各个部分的参数:为验证理论分析的有效性,对两种不同类型压缩机在正常工作条件下的内部工作状态进行测试;将计算结果与试验数据进行比较后的结果表明,两者有较好的一致性,因此研究结果可用来预测滑片式压缩机的工作状态。

The pressure states and power compositions of rotary vane air compressors under working are analytically studied. The results are validated by comparing the theory data and experiment data, which come from pressure-temperature sensors and galvanometers equipped in the compressors. In pressure analysis, pressure process is divided into six sections and six simultaneous pressure equations are established for these six sections respectively. Similarly, four simultaneous power equations are established for four power sections respectively. Then, the pressure and power values are obtained by establishing the theory models. The pressures and powers of two different compressors are tested under normal working conditions, The analytical results are in good agreement with the experiment data, which validate the theory analysis. The study is useful to predict the working performance of rotary vane air compressors.
