1、异相型游梁式抽油机设计摘要抽油设备中，以游梁式抽油机最为普遍，数量也最多。游梁式抽油机具有机构简单、可靠性高等优点，因而在油田得到了广泛应用。随着石油工业的发展，目前，为了增加抽油机的适应性、可靠性、经济性和先进性，提高抽油效率，减少动力消耗，改善抽油机的运动特性、动力特性与平衡特性。因此国外抽油机的总的发展趋势是向着超大载荷，长冲程，低冲次，精确平衡，自动化，智能化，节能化，高适应性方向发展。异相型游梁式抽油机是油田应用最为广泛的一种节能型抽油机。它的设计原理与方法对抽油设备具有通用性。本文介绍了异相型游梁式抽油机工作原理与节能原理，进行了运动学和动力学分析
2、计算、平衡计算。为此，将曲柄回转运动分成24等分，逐点计算悬点的光杆因数、扭矩因数、加速度、载荷值；曲柄扭矩计算、平衡率计算及交变载荷系数计算等。由于计算工作量大，在手算基础上采用了计算机的Excel软件优选了抽油机的几何尺寸。对主要部件进行了选择计算，合理选择电动机和双圆弧齿轮减速器，设计了窄V带传动装置。最后对各结构进行了应力和强度校核。设计显示：如果异相型游梁式抽油机的几何尺寸得到优化，节能效果是显著的。关键字：异相型抽油机，扭矩因数，悬点载荷，净扭矩AbstractPumpingequipment,withthemostcommonbeampumpin
