摘要
游梁式抽油机的优化设计必须充分考虑抽油机载荷的特殊性。根据对所选择的各种目标函数优缺点的分析,提出了以有效扭矩作为目标函数,并通过约束条件对峰值扭矩及绝对值最大负扭矩进行限制的数学模型。分析了按各种方案对冲程4.2m10型抽油机进行计算的结果,指出该模型可使抽油机整体设计达到最佳状态。
The specific characteristics of the load on pumping unit must be carefully thought over in the optimum designing of beam pumping units. After analyzing the advantages and disadvantages of different objective functions selected, a mathematical model taking the effective torque as objective function with peak torque and negative maximum torque as restraint conditions is presented. Checking calculations show that the pumping unit designed by means of this mathematical model provides optimum conditions.
