1) hydraulic feedback
液压反馈<液>
2) hydraulic feedback
液压反馈
1.
Speed control system with high speed spring coil slice and hydraulic feedback of steam turbine;
汽轮机高速弹簧片调速器调节系统及液压反馈
2.
Because of existing heavy oil pump swabbed heavy oil,usually the resistance of plunger downwards was great,and hydraulic feedback was small,resulting in flexural deformation of sucker rod and pump efficiency low,seriously,eccentric wear of rod and pipe in operation of oil well.
现有抽稠泵抽吸稠油时,往往出现柱塞下行阻力较大,液压反馈力小,致使杆柱下行屈曲变形,泵效低,严重时杆管之间的偏磨倒井问题突出。
3) double-way hydraulic feedback force

4) Inverse hydrostatic control
液压反馈控制
5) hydraulic feedback
液力反馈
1.
Study of hydraulic feedback and non-tubing production technology;
液力反馈无油管采油技术
2.
A new hydraulic feedback subsurface pump for viscous oil recovery;
新型空心液力反馈稠油泵及其结构优化设计
3.
Analysis of flow rate and polished rod load for hydraulic feedback hollow sucker rod pump;

6) electric liquid feedback
电液反馈
补充资料：液压式液面计（liquidpressurelevelgauge）
液压式液面计（liquidpressurelevelgauge）
金属的杜瓦容器、低温的液化器、贮槽以及槽车等用来观察内部液面高度的装置为液面计。盛有密度为ρ、高度为h的液体的容器底部的压强等于液体表面的压强P0加上液体的静压强ρgh，将此表面和底部的压强分别用毛细管引出到另一盛常温液体的指示容器的两端，在这压力差的作用下指示容器的液面出现一高度差，通过校正即可指示出低温容器中的液面高度。
