摘要
异形游架式抽油机是以常规抽油机为基础模式而研制出的新机型，它采用变径圆弧状的游渠后臂，游梁与横梁之间采用柔性件连接结构，在主要结构上具有常规游渠式抽油机简单、牢靠、耐用等特．大．在性能上易于实现长冲程，并且具有突出的节能特点。。
The new type beam -pumping unit is developed on the basis of conventional beam-pumping u-nit- It uses the variable diameter ciucular-arc rear arm of walking beam, and the flexible connectionbetween the walking beam and the cronbeam. it has the advantuges campared with the conventionalbeam unit that are simple, firm, durable, easy to realize the long stroke and the outstanding energysaving etc
