一、问题的提出 某一三级压缩、V型、风冷的微型、高压、高速活塞式空气压缩机,其性能检查是这样的:在一定容积储气罐下,当排气压力由零充至14.7MPa时,其时间不大于30min。在寿命试验过程中,充填时间差别较大,每次测量的排气量有差别,如果用图表示的话,如图1。为了寻找原因,我们在Ⅱ、Ⅲ级吸气阀处 First, the issue put forward A three-stage compression, V-type, air-cooled miniature, high pressure, high speed piston air compressor, the performance check is this: under a certain volume of gas tank, when the exhaust pressure from zero charge To 14.7MPa, the time is not more than 30min. In the life test process, filling time difference is larger, each measured displacement of the difference, if the chart shows, as shown in Figure 1. In order to find the reason, we are in the Ⅱ, Ⅲ level inhalation valve
