活塞式空气压缩机低频调速时的气阀运行特性分析

Analysis on Air Valve Movement Characteristic in Low Frequency Adjustment in the Piston Air Compressor

对空气压缩机在低频运行时气阀工作特性进行了数学分析与模拟,确定了使压缩机气阀正常工作及不发生延迟关闭的频率下限,可供变频调节压缩机选择频率范围作参考。

Carried out the mathematical analysis and the simulation to' air valve in low frequency working. The lower frequency limit was determined when the compressor air valve works normally and does not presents delay closure. It can offer a reference for frequency range selection of the variable frequency adjustment compressor.
