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。
