气阀是制冷压缩机重要部件之一.它对压缩机的性能有很大影响.气阀升程是气阀的主要尺寸.高升程使流经气阀的压力损失降低,但也由此而加大了余隙容积并降低了寿命.因此,必定有一个气阀升程的最佳值.本文提出了确定最佳升程的方法.
The air valve is one of the most important components of a refrigeration compressor and it has a great influence on the performance of the compressor.The valve lift is the main size of the valve.High lift reduces the pressure loss through the valve but also Increased clearance volume and reduced life, therefore, there must be an optimum valve lift.This paper presents a method to determine the optimal lift.
