Studied the relationship of elastic vib ration of rod and working conditions of pump, proposed a method to analyze indic ator diagram, calculate parameters such as swab rate, depth of plunger and depth of break by elastic vibration rule.

• 为此,研究了抽油杆弹性振动规律和泵工作状况的内在联系,提出了利用弹性振动规律来分析示功图及计算抽汲速度、泵挂深度和断脱深度等参数的方法。
