Question

针对目前现有的常规游梁式抽油机由于自身的结构限制，存在装机功率大，大马拉小车的现象，电动机效率低。其主要原因是常规游梁式抽油机为曲柄平衡，启动功率大。为了解决这一问题，设计了一种新型的无级变速抽油机，以达到节能降耗，降低运行成本的目的。
该新型抽油机的设计特点是：将常规游梁式抽油机的减速箱变为无级变速装置，曲柄平衡变为游梁平衡，可以进行软启动，降低装机功率，提高电动机的运行效率和功率的利用率。实现驴头上下往复摆动的方式很多，其中四连杆机构是最优选的结构。其结构简单，可靠性高。驴头摆动换向平稳（换向时速度等于零），所以新型无级变速抽油机仍然采用四连杆机构。
对新型无级变速抽油机驴头悬点运动规律进行精确分析，通过悬点冲程长度，估算四连杆尺寸，并着重对无级变速箱曲柄轴扭矩进行计算，编写了相应的计算程序，对不同数据下所得到了扭矩曲线进行比较，选择扭矩曲线比较平稳，峰值小且无负扭矩的一组作为设计参数，对主要零部件进行结构设计、力学分析及强度校核。
通过计算得出这种新型无级变速抽油机的优点在于：
1.无级变速箱扭矩的输出值比常规抽油机低32.9%；
2.无负扭矩、均方根扭矩要比常规型抽油机小30%；
3.电动机的平均启动功率比常规抽油机的启动功率低50.9%；
4.电动机实耗功率比常规型抽油机降低11.4%。

In view of the current existing conventional the beam pumping unit because of their limited structure, there are installed power is great, the phenomena of Malawi, motor efficiency is low. The main cause is the conventional the beam pumping unit for crank balanced, start big power. In order to solve this problem, design a kind of new stepless speed of the pumping unit, in order to achieve saving energy consumption, and reduce the operating cost purposes.
The new design characteristics of the pumping unit is: will the beam pumping unit of conventional reducer become stepless speed device, crank balanced to swim LiangPingHeng, soft start, reduce the installed power, enhancing the efficiency of motor and power utilization. Realize the donkey head down the way many swung repeatedly, including four bar linkage is the optimal structure. Its simple structure, high reliability. The donkey head swinging the reversing stable (the speed is equal to zero), so new CVT pumping unit still using four bar linkage.
For new CVT pumping the donkey head hanging point movement rule of accurate analysis, through the horsehead stroke length, estimate the four connecting rod size, and focuses on the crank shaft torque transmission stepless calculated, write the corresponding computational procedure for different data of income compared to torque curve, choose torque curve smoothly, peak and no small bear of a group of torque as design parameters, the main parts structure design, mechanics analysis and strength check.
The calculations this new type of stepless speed of the unit advantage is that:
1. Stepless transmission torque output value of the pumping unit is 32.9% lower than normal;
2. No negative torque, root mean square torque than conventional pumping unit type small 30%;
3. The average start motor power than conventional pumping unit start-up power low 50.9%;
4. Motor power consumption than conventional type of pumping unit is reduced by 11.4%.
