漏失量
1.
Study of the method for calculating the clearance leakage between the plunger and the barrel of oil well pump;
抽油泵柱塞与泵筒间隙漏失量计算方法的研究
2.
By studying the laws of fluid flowing in the wedged clearance, accurate and approximate equations are derived for calculating the annular leakages as pump barrel being concentric and eccentric with the plunger.
根据柱塞和泵简在井下工作时受井液压力、温度和轴向力等因素的影响,使环隙沿柱塞长度近似呈倒锥形,通过对液体在楔形缝隙中流动规律的研究,导出了泵简与柱塞同心和偏心两种情况下的环隙漏失量的精确和近似公式,这些公式可直观反映出间隙和偏心量的大小对漏失量的影响。
3.
Sucker pump with automatic compensate gap its plunger as nonmetal elasticity material was developed in order that friction between plunger and pump barrel was reduced, gap leakage between plunger and pump barrel was decreased, the cost of sucker pump and the expense of pump inspection and operation were reduced by aming at inelasticity was .
针对常规抽油泵应用时存在的不适应性入手,以降低柱塞与泵筒之间的摩阻、减少柱塞与泵筒的间隙漏失量、降低抽油泵成本和检泵作业费用为目的,研制了一种采用非金属弹性材料作为抽油泵柱塞弹性元件的间隙自补偿柱塞泵。
