摘　　要：论述了气体在液压系统中的存在形式、液压系统中三种形态气体的特点及相互转换关系;分析了油液中空气的来源,研究了油液含气的危害,重点描述了气穴的种类,气蚀产生的机理及易发生的部位;最后针对液压系统气体污染问题,提出防气、排气与脱气的方法。Three different status of air in hydraulic system, the characteristic and interchanging of different status air in hydraulic system were introduced. The source of air was analyzed and harm to the system was studied. The type of cavitation, cavitation wear process, and cavitation wear sites were discussed. Deaerator and degasser methods were suggested to prevent air contamination.
