Simulation of Cam Tri-proportion Controller

凸轮式三组元燃料配比器是某种热动力水下航行器推进系统的关键组件,其配比精度直接影响燃料的效率和动力系统的性能。因此其各项指标之间的关系,是三组元燃料配比器工作中的重要问题。通过对该型燃料配比器的性能仿真,得出该配比器转速、压差、流量和配比精度之间的关系,用以研究其在一定压差和流量范围内的工作性能。

Cam tri-proportion controller is one key part of a kind of under-water craft engine propeller system. The proportional precision of the tri-proportion controller is very important for exploiting the energy efficiency of thefuel, and determining the performance of engine systerm. So the relationship between the indicators of cam tri-pro- portion controller is the important issues of tri-proportion controller research. According to the simulation of a tri-proportion controller, the figure between rotational speed, differential pressure, flow rate and accuracy of tri-proportion controller is got, the performance of cam tri-proportion controller in a certain range of differential pressure andflow rate is researched.
