摘要
针对目前传统游梁式抽油机存在能耗高、效率低等问题,提出了一种基于液压传动的抽油机,为验证其可行性,建立了液压并联驱动抽油机液控系统模型,推导了液压泵功率、流量和蓄能器总容积的数学模型,通过仿真分析验证了模型的正确性,讨论了液压杆负载和蓄能器容积对液压控制系统仿真结果的影响。最后通过现场试验验证了液压抽油机的节能效果。研究发现:在冲程冲次不变、产液量相近的情况下,液压并联驱动抽油机的地面效率远大于传统游梁式抽油机,能明显提升地面抽采设备的效率。
Aiming at the problems of high energy consumption and low efficiency of traditional beam pumping unit,a pumping unit based on hydraulic transmission is proposed.In order to verify its feasibility,the hydraulic control system model of hydraulic parallel drive pumping unit is established,and the mathematical models of hydraulic pump power,flow rate and total accumulator volume are derived.The correctness of the model is verified by simulation analysis,and the influence of hydraulic rod load and accumulator volume on the simulation results of hydraulic control system is discussed.Finally,the energy-saving effect of hydraulic pumping unit is verified by field test.It is found that the ground efficiency of hydraulic parallel driving pumping unit is much higher than that of traditional beam pumping unit under the condition of constant stroke times and similar liquid production,which can obviously improve the efficiency of ground pumping equipment.
