摘要: 为了研究鱼雷变量燃料泵的流动特性, 文中提出了一种使用标准模版实现静缸式柱塞泵的研究方法, 通过3D建模软件UG与计算流体力学(CFD)仿真软件PumpLinx完成对柱塞泵的仿真。在此基础上, 进一步对泵的流量、压力和空化进行了仿真和分析。仿真结果表明, 变量泵不会产生空化现象, 但流量脉动较大且高低压过渡不平稳, 这些结论对变量泵的改进设计有一定的参考价值。

Abstract: To reveal the flow characteristics of the variable fuel pump for a torpedo, this paper proposes a hydraulic simulation method of the static variable cylinder valve axial piston pump by using the rotary cylinder plunger pump template in the professional pump computational fluid dynamics(CFD) simulation software PumpLinx, and further simulates and analyzes the flow, pressure and cavitation of the pump. Simulation results show that this pump does not produce cavitation, but there exists obvious pulse offlux with unsmooth transition. This research may benefit the improvement and design of the fuel pump with variable valve angle.
