ROTAFLEX— 90 0胶带式抽油机是一种纯机械传动的链条 -胶带式抽油机 ,其最大载荷为 1 59 95kN ,最大冲程为 7 3m ,最低冲次为 0 5min- 1 ;采用长寿命重型胶带给抽油杆柱传递动力 ,其弹性缓冲作用可降低抽油机换向冲击对井下泵及抽油杆柱的不良影响 ,有利于降低峰值载荷、扭矩和电流。这种抽油机换向少 ,减少了冲程损失及管杆泵的磨损 ,从而可提高泵效 ,延长检泵周期。在中原油田的现场使用情况与常规 1 4型抽油机相比 ,产液量和产油量分别增加 49 8%和 48 6% ;采液单耗和采油单耗分别下降 4 4kW·h/t和 1 3 1kW·h/t,节能 1 0 %～ 40 %。
ROTAFLEX-90 0 Tape Dispenser is a purely mechanical transmission chain-tape pumping unit with a maximum load of 1 59 95 kN, a maximum stroke of 7 3 m and a minimum stroke of 0 5 min -1; long life Heavy-duty tape delivers power to the sucker rod string. Its elastic cushioning effect can reduce the negative impact of the reversing impact of the pumping unit on the downhole pump and sucker rod string, which helps to reduce the peak load, torque and current. This pumping unit commutation less, reducing the stroke loss and pipe pump wear and tear, which can improve pump efficiency, extend the pump cycle. In the field of Zhongyuan Oilfield, compared with the conventional 14 pumping unit, the liquid production and oil production increased by 49.8% and 48.6% respectively; the unit consumption of liquid production and the unit consumption of oil production decreased by 4 4 kW · h / t and 1 3 1kW · h / t, energy saving 1 0% ~ 40%.
