油井泵体用直缝电阻焊钢管 - According to non - newtonian fluid mechanics theory and mathematical method , conbined with plunger moving property , the hypothesize fluid is imcompressive , hydraulic radius of flow of liquid in crevice is very little , and it is laminar flow , the flow is treated fixed continuous flow at every instant position of plunger , equation of motion and boundary condition were set up in condition of concentric and eccentric of pump barrel and plunger
运用非牛顿流体力学理论和数理方法，结合抽油泵柱塞运动特点，假设液体为不可压缩的，液体在缝隙中流动的水力半径很小，呈层流流动，柱塞在每一位置的瞬间，流动做定常流处理，建立了泵筒与柱塞同心和偏心两种情况下运动方程和边界条件，引入无量纲坐标、无量纲速度和柱塞与泵筒偏心配合时的缝隙高度，并给出缝隙流流速、流量的解析解。
