在阿道尔夫泵阀运动微分方程的基础上,研究了抽油泵泵阀的运动规律。为了解决阿道尔夫泵阀运动微分方程在泵阀开启初期的奇点问题,综合考虑了液体可压缩性、泵阀运动的魏氏效应对泵筒内液体连续流条件的影响以及泵阀运动的动力特性,建立了泵阀运动数学模型。同时,应用数值积分法建立了泵阀运动规律的仿真模型,并编写了泵阀运动的计算机仿真程序。室内台架模拟试验结果表明,建立的泵阀运动规律数学模型具有较高的仿真精度。
On the basis of Adolf’s differential equation of motion of pump valve, the movement rule of pump valve is studied. In order to solve the singularity problem of Adolf’s differential equation of pump valve in the early stage of valve opening, the influence of liquid compressibility, Wiegand effect of valve movement on the continuous flow of liquid in the pump cylinder and the valve movement The dynamic characteristics of the pump valve movement established mathematical model. At the same time, the simulation model of pump valve movement was established by numerical integral method and the computer simulation program of pump valve movement was compiled. The indoor bench simulation test results show that the established mathematical model of pump valve movement has high simulation accuracy.
