摘　　要：为了进一步提高鱼雷热动力系统启动的可靠性,在分析柱塞式燃料泵结构特性的基础上,从物理学角度得出了系统启动的理论必要条件,通过对柱塞式燃料泵的试验数据和鱼雷实航数据的比较分析,提出了使柱塞式燃料泵及燃料供应系统具有良好启动特性的设计准则,即燃料泵相关设计参数必须满足P1max/P0′<1/K(V1/V0+1)。研究得出,柱塞式燃料泵在启动阶段,燃料为气体状态时,其进出口压力的比值达到某一极限值时燃料泵就不能启动。To further enhance the starting reliability of torpedo thermal power system,the theoretical necessary condition of system starting is obtained in the view of physics by analyzing the structural feature of a plunger type fuel pump.By analyzing the data from test of the fuel pump and sea trial of a torpedo,a design criterion is offered to achieve better starting characteristics of the plunger type fuel pump and the fuel supply system,that is,the fuel pump＇s design parame-ters must satisfy P1max/P0＇1/K（V1/V0＋1）.It is found that the fuel pump can not start if the ratio of inlet to outlet pressure reaches a limit when the plunger type fuel pump works in starting phase and the fuel is in gaseous state.
