摘要
目前,现场平衡调整主要依靠人工调整平衡块实现,一方面需要停井操作,影响生产;另一方面频繁调整造成工作量大、调整不及时,也存在安全隐患。针对上述问题,应用了抽油机在线平衡调整装置。在线平衡调整装置通过在抽油机的游梁上加装配重,由遥控器控制太阳能驱动系统使配重前后移动,改善系统受力状况,达到平衡调整的目的。经现场试验及其应用效果分析表明:该装置可实现抽油机不停井平衡调整,在配重调整范围内,可调整电流2A、功率2 kW;平均日节电9.8 kWh;当平均功率平衡度控制在70%~120%范围时,抽油机既能达到最佳平衡范围,又能实现最佳能耗状态。
At present,the adjustment of balance on site mainly relies on manual adjustment of the balance blocks.On one hand,the operation needs to stop the pumping well,which affects the production;on the other hand,heavy workload is caused by frequent adjustments,and if the adjustment is not in time,security risks would occur.According to the above problem,the online balance adjustment technology for pumping units is applied.Through adding weight to the beam of the pumping unit,it controls the solar powered system by remote control to remove the weigh and improve the system stress state,and then the purpose of balance adjustment can be achieved.The field test and application effect analysis show that the device can adjust the balance of pumping units without stopping,and 2 A of current and 2 kW of power can be adjusted within the range of the additional weight;it can save power of 9.8 kWh averagely per day;when the average power balance is controlled in the range of 70%to 120%,the pumping unit not only can achieve its best range of balance,but also can achieve its best state of energy consumption.
