摘要
针对普通游梁式抽油机存在悬点载荷波动、冲程短、悬绳磨损严重的缺点,设计了可随冲程变化对平衡力臂进行调节的游梁平衡滑轮,来改善电机功率负载曲线峰值。并采用钢带代替悬绳固定在平衡滑轮上,滑轮在改变力臂过程中驱使钢带随滑轮转动而绕在其上,以此来达到增大冲程、减小摩擦损耗的目的。对该抽油机机构尺寸进行了优化设计,确定了各个杆件,及重要平衡部件的结构尺寸。
The machine has suspended load fluctuation, short stroke, hanging rope wear serious shortcomings of ordinary beam pumping, the balance arm to adjust the balance beam with the change of the pulley stroke design, to improve the motor power load curve. The utility model is characterized in that the steel belt is used to replace the hanging rope to fix on the balance pulley, and the pulley drives the steel belt to rotate around the pulley in the process of changing the arm force, so as to achieve the purpose of increasing stroke and reducing friction loss. The size of the pumping unit is optimized, and the structural dimensions of each member and the important balance components are determined.
