| 摘 要： | 抽油机电液伺服模拟系统伺服阀前压力脉动的主要原因是油泵输出压力的脉动和伺服阀输出流量的变化．伺服阀前压力脉动和伺服阀输出流量的变化．伺服阀前压力脉动会影响抽油机悬点运动规律的模拟精度且冲次愈高影响愈严重．抑制和减弱伺服阀前压力脉动的途径是合理选用液压滤波器件，对有蓄能器滤波和无蓄能器滤波两种工作过程中的伺服阀前村力脉动进行了数字仿真，仿真结果与理论分析基本相符

| Abstract: | The main reason of pressure pulsation before the servovalve of electro hydranlic servo simulation system of well pumping unit is the output pressure pulsation of the oil pump and flow change of the servo valve.The simulation precision of hanging point movement will be influenced by the pressure pulsation before the servovalve,and the more the stroke occurs,the more serious the influence will be.The way of restraining and weakening the pulsation is to select rational hydraulic parts for the valve filter.Numerical simulations of pressure pulsation before the servovalve were made for the two working processes with and without accumulator filter.The results of the simulations comform basically with the theoretical analysis. |
