1、 8型型双滚筒式双滚筒式超长冲程抽油机超长冲程抽油机动力与主体结构设计与分析动力与主体结构设计与分析 摘摘 要要：为了适应稠油开采，设计了超长冲程双滚筒抽油机。首先，描述了滚筒抽油 机在国内外的发展概况，对滚筒抽油机的结构、性能及优缺点进行阐述，从而提出了 双滚筒抽油机的设计。其次，从原始数据开始计算设计了配重机构，选定了电动机, 为了克服，传统滚筒抽油机的换向装置不稳定的缺点，选用了变频调速器，来实现电 机的正反转，并调节电机的转速以改变冲次及冲程。然后根据，抽油杆的最小曲率半 径设计了工作滚筒，并且在此基础上，设计了结构简单重量轻的导向轮。最后，设计 滚筒式抽油机的零部件结构，包括减速器，

2、机架等，并绘制了装配图和零件图。 通过此设计降低了能耗，增大了抽油机的冲程，实现了通过变频调速器调节电机 调速及换向。 键词：键词：双滚筒抽油机；变频调速器；超长冲程； The design and analysis of the dynamics and main body structural of 8 double-drum drum long stroke pumping unit Abstract: In order to meet the heavy oil, designed long-stroke double drum pumping unit. First of all,

3、described the development of long-stroke double drum pumping unit at home and abroad , expound the structure , performance , advantages and disadvantages of the drum pumping, and then come up with the design of long-stroke double-drum pumping unit. Secondly, designed of the balance weight mechanism

4、and selected electromotot in the premise of the raw data. In order to overcome the shortcomings of instability of the traditional drum pumping unit, selected the VVVF (variable voltage and variable frequency device), the choice of a VVVF make it easy to reverse the motor and adjust motor speed to th

5、e changing speed and long stroke of the pumping unit. Then, according to the minimum radius of curvature of Carbon fiber rods, designed the working roller. and on this basis, design a simpler and lighter guide rollers. Finally, designed components of long-stroke double-drum pumping unit, including r

6、eduction gear and framework ect, and mapped the assembly and part drawings. This design reduces energy consumption and increase the pumping stroke, realized the speed adjustiment and orientation shift.
