1986年以来,我厂研究出常规及异相曲柄偏置型抽油机的平衡块最优位置和曲柄销最优偏置角公式。此后又导出了双驴头抽油机的最优平衡重的计算公式及曲柄销最优偏角的计算方法。今天又传出喜讯,旋转驴头的光杆位置函数PR及悬点加速度a的计算公式被推导出来了,而且旋转驴头的运动分析和最优参数计算软件运行成功。至此,我厂已具备上述四种类型抽油机的运动分析、尺度综合和选优软件。
Since 1986, our factory has developed the optimal position of balance weight and the optimal offset angle formula of crank pin for conventional and out-of-phase crank-biased pumping units. After that, the calculation formula of the optimal balance weight of double donkeyhead pumping unit and the calculation method of the optimal declination angle of the crank pin were derived. The good news came again today that the formula for calculating the position of the light bar and the acceleration a of the donkey head was deduced. Moreover, the motion analysis of the donkey head and the calculation of the optimal parameters were successful. So far, I plant has the above four types of pumping unit motion analysis, standardization and optimization software.
