【摘要】 通过对旋叶式压缩机中背压腔、工作容积和压缩机内油路之间的泄露、和能量的转化研究,得出了一种背压腔压力的计算方法。对不同转速、排气压力、蒸发温度下背压腔的压力进行了测试,分析了其变化规律对压缩机性能的影响。更多还原

【Abstract】 Considering the leakage and mass transfer between back - pressure cavity, compression chamber and oil system, the thermodynamic model of the back - pressure cavity for rotary vane compressor has been developed. To analyze the effect of back- pressure cavity on compressor performance, a test rig is built, in which the pressure can be measured under the conditions of various speed, discharge pressure and evaporating temperature.更多还原
