College of Marine Engineering of Northwestern Polytechnical University, Xi′an 710072, China

摘要

摘要: 三组元比例控制器是水下热动力能源供应系统的关键组件, 其配比精度的高低, 对推进剂能效的发挥起着决定性的作用。对罗茨式比例控制器, 其比例控制精度主要受每路流体泄漏量的影响。通过对罗茨式三组元比例控制器的力学和泄漏量分析, 建立了罗茨比例控制器的数学模型, 在MATLAB环境下, 对其工作过程进行了数值仿真, 获得了诸如面积利用系数、定子内径、叶轮总高度以及端面间隙等重要参数的变化规律, 并分析了这些参数变化对比例(控制)精度的影响, 为其研制提供了理论依据。

Abstract: Tri-propellant proportion controller is a key part of underwater heat engine energy supply system, its proportional precision is very important for exploiting the energy efficiency of the propellant. And for Roots tri-propellant proportion controller, its proportional control precision is mainly affected by the leakage volume of each way. In this paper, based on the analysis of mechanics and leakage volume of Roots tri-propellant proportion controller, a mathematical model is established, and numerical simulations are performed via MATLAB. Consequently, the variation rules of the important parameters, such as the utilization factor of area, the interior diameter of stator, the total height of impeller, and the end face clearance, are obtained. And the influences of these parameters on proportional precision are analyzed. This study may be applied to the development of Roots tri-propellant proportion controller.
