活塞式空压机和气动冲击器的工作效率,在使用气液混合物作为工作介质时有所提高。空气和水的混合物是其中应用得最广泛的一种气液混合物。这是因为这种工作介质无毒、价廉,而且其组成元素在自然界中比比皆是。文献中关于活塞式空压机和气动冲击器压缩和膨胀过程的理论及实验研究的一些数据表明:以介质形式存在于空气中的水和不规则分散的水珠蒸发得极少,因此不能采用以水完全蒸发为条件的这些过程的一般计算方
The working efficiency of piston air compressors and pneumatic impactors has been improved when using gas-liquid mixtures as the working medium. A mixture of air and water is one of the most widely used gas-liquid mixtures. This is because the working medium is non-toxic, inexpensive, and its constituent elements abound in nature. Some of the theoretical and experimental studies in the literature on the compression and expansion of piston air compressors and pneumatic impactors show that water present in the medium and irregularly dispersed water droplets evaporate very little and can not be used The general calculation of these processes, conditional on the complete evaporation of water
