摘要
建立考虑过载的流量调节器静态数学模型,研究过载影响调节器静态特性的规律,为预估过载对发动机性能的影响提供参考。研究表明:纵向过载单一因素引起的流量偏差、启调压降偏差与过载系数近似呈线性关系,过载不改变流量特性的线性度和负载特性差率。
Static mathematics models taking overload into account for liquid-flow regulator were constructed to study the effects of overload on static characteristic of the liquid-flow regulator, and to provide a reference for estimating the effects of overload on the engine performance in advance. The research shows, both the mass flow rate deviation andthe lowest operating pressure-drop deviation caused by longitudinal over/oad are approximately linear with the overload coefficient, and the overload does not affect the linearity of the flow characteristics or the error rate of load characteristics.
