【摘要】：针对油田在用数字化抽油机存在自平衡范围小,手动补充平衡块调整不及时,造成抽油机经常处于不平衡状态,以及游梁尾部太长引起的整机稳定性较差和故障多等缺陷。研制了一种新型电动平衡调节装置,其安装在数字化抽油机不受平衡重冲击力的部位,仅传递转矩,且结构简单、工作可靠、无易损件。该装置的内部设有调节平衡范围的放大机构,避免了人工手动调整的弊端,可满足抽油机额定载荷50%~100%的平衡能力。经过近2a的运转试验,抽油机的平衡度始终保持在90%~110%,工作可靠。应用该装置设计的大摆角抽油机结构紧凑、后臂短、稳定性好、可靠性高;还可对油田在用常规抽油机进行数字化改造,使其实现数字化抽油机的功能,具有较好的经济效益和社会效益。
[Abstract]:In view of the small self-balance range of digital pumping units in use in oil fields and the untimely adjustment of manual supplementary balancing blocks, the pumping units are often in unbalanced state. As well as the defects such as poor stability and many faults caused by the too long end of the beam, a new type of electric balancing and regulating device is developed, which is installed in the position where the digital pumping unit is not subjected to balanced heavy impact and only transmits torque. The utility model has the advantages of simple structure, reliable operation and no easily damaged parts. The inside of the device is equipped with a magnifying mechanism to adjust the balance range, thus avoiding the drawback of manual adjustment. It can satisfy the balance ability of the pumping unit with rated load of 50% and 100%. After nearly 2 years of operation test, the balance of the pumping unit has been kept at 90% and 110%. The large swing angle pumping unit designed by this device has the advantages of compact structure, short rear arm, good stability and high reliability. The conventional pumping unit can also be digitally reformed to realize the function of the digital pumping unit, which has good economic and social benefits.
