液压反馈抽稠泵

液压反馈抽稠泵液压反馈抽稠泵
  1. 由于液压反馈式抽稠泵的特殊结构,在下冲程时,液柱载荷作用在泵上,以增大悬点载荷帮助抽油杆柱顺利下行,致使其杆柱设计方法与普通泵不同。

    The down stroke , due to the special structure of hydraulic feedback pump , the liquid column loads on the pump to increase rod load to help sucker rod smoothly downstream , resulting in the rod string design method is different from the ordinary pump .
