该研究成果属应用理论研究范畴,它在理论上阐明了液压管路及元件节流气穴发生的机理,指出了在液压系统中存在扩散型和蒸汽型两种可能的气穴类型以及相应的形成条件,建立了描述高压管路及元件节流气穴起始条件的数学模型、判别准则及主要影响因素,证明了以节流口前后压力比作为衡量气穴状态的合理性及可行性,表明了影响气穴临
The research results belong to the field of applied theory. It theoretically illustrates the mechanism of throttling cavitation in hydraulic piping and components, and points out that there are two possible types of cavitation in diffusion and steam formation in hydraulic system and corresponding formation Conditions, established a mathematical model describing the initial conditions of high pressure piping and components throttling cavitation, criteria for discrimination and the main influencing factors, proved the rationality and feasibility of measuring the cavitation state before and after the throttle orifice, Affect cavitation Pro
