考虑了魏斯特法尔现象,本文介绍求泵阀运动公式的两类方法:近似解法和解微分方程法。这两类方法得到的结果均说明泵阀运动存在滞后现象。本文对解微分方程法得到的几个特解进行了较为详细的讨论,从而给出了更接近实际情况的泵阀运动今式,提出了一些新看法。
Considering the phenomenon of Weisitefar, this article describes two types of methods for calculating the pump valve motion formula: approximate solution and differential solution method. The results obtained by these two methods all indicate that there is a hysteresis in the pump valve movement. In this paper, some special solutions to the differential equation method are discussed in more detail, which gives a new approach to the valve movement that is closer to the actual situation.
