摘  要:
建立了往复泵自动阀运动的二阶微分方程组,并用龙格-库塔法由计算机求得阀运动的数值解。研究了阀簧参数和泵转速对泵容积效率的影响,得到了泵容积效率随阀簧刚度、初始长度和泵转速变化的规律,对提高植保机械用泵的容积效率有参考价值。

摘  要:
In this paper a set of second order differential equations for the valve motion of reciprocating pumps is set up. The solutions are drawn from numerical calculations of these differential equations by using Runge-Kutta method on computer. The paper also discusses the effects of both the valve spring parameters and the pump rotating speeds on the volume efficiency. Therefore, the patterns of the relationship between the rigidity, the initial length of the valve spring and the rotating speeds can be found.It gives a reference to the work of improving the volume efficiency of the pump used for plant protec-tion.
