摘　　要：液力反馈型空心杆抽油泵在一定程度上缓解了抽油杆下行困难的问题。对流量和光杆载荷所作的分析表明 ,这种泵会大幅度增加上冲程悬点载荷 。Hydraulic feedback hollow sucker rod pump solves the problem of downward movement of the hollow rod on a certain extent. Analysis of the flow rate and polished rod load shows that, during the up stroke, polished rod load is increased greatly, flow rate is decreased greatly at the same time.
