摘　　要：为深入理解异相型抽油机的工作特性,以10型机为研究对象,对比分析了常规机和异相机的运动特性、负载特性和扭矩特性。理论分析结果表明:异相机的扭矩因数曲线更接近正弦曲线,且峰值减小。悬点速度和加速度峰值都低于常规机,具有节能、降载及运行平稳等特点。In order to understand thoroughly the operating characteristics of phased beam pumping unit （PBPU）, we compare the conventional beam pumping unit（CBPU） and PBPU on movement characteris- tics to study 10 -type machine, loading characteristics and torque characteristics. The analysis results show that torque curve of PBPU is closer to sine curve than CBPU with smaller peak value. The peak val- ue of suspend velocity and acceleration are both lower than CBPU, which have characteristics such as en- ergy conservation, low load and steady working.
