油泵空穴是液压基础理论中的一个比较重要的内容。对这个问题进行探讨,有利于本单元教学内容的深化,加强基本理论;同时,对正确设计吸油管道,或合理确定油泵的安装高度,以保证油泵的正常工作,有着实际意义。所谓“空穴”,或称“气穴”,是指液体中出现气泡,占据部分空间,致使液体变为不连续的介质的现象。在液压系统中,压力低于空气分离压的区域,原来溶解于油液
Pump cavity is a hydraulic theory of the more important content. The discussion of this issue is conducive to the unit deepening of teaching content, strengthen the basic theory; the same time, the correct design of the suction pipe, or reasonable to determine the installation height of the pump to ensure the normal operation of the pump, of practical significance. The so-called “hole”, or “cavitation”, refers to the phenomenon of bubbles in the liquid, occupy part of the space, resulting in liquid into a discontinuous medium. In the hydraulic system, the pressure is lower than the pressure of air separation area, the original dissolved in the oil
