Most turbine designs are based on the continuous rotating turbine structure. In this paper, a novel hydraulic balanced turbine (HBT) with a symmetrical blade structure that can be used in a hydro-environment is proposed. The turbine, which uses the hydraulic impact of the nozzle jet and balanced turbine blade design in stability control, could be used to control stability in certain applications, e.g. in drilling engineering. This is a completely new way of thinking about turbine design. Because of the special blade design of the HBT, when the nozzle deviates from the balance position, the HBT will be restored to the balance position under the action of external moment. The follow-up performance of the HBT is directly related to the rotational speed of the nozzle. The theoretical and numerical solutions in this paper have good consistency. Modern computational resources allow computational fluid dynamics to be an integral part of turbine design. The simulation results proved that this innovative design is feasible and has potential application prospects. The HBT realizes the ‘soft’ connection between the controlled stable platform and the actuator in the vertical drilling tool, which can significantly improve the control precision of mechanical vertical drilling.

大多数涡轮机设计基于连续旋转涡轮机结构。在本文中，提出了一种新型水力平衡涡轮机（HBT），其具有对称叶片结构，可用于水力环境。在稳定性控制中使用喷嘴射流的水力冲击和平衡涡轮叶片设计的涡轮机可用于控制某些应用中的稳定性，例如在钻井工程中。这是一种全新的涡轮设计思维方式。由于HBT特殊的叶片设计，当喷嘴偏离平衡位置时，HBT会在外力矩的作用下恢复到平衡位置。HBT的随动性能与喷嘴的转速直接相关。本文的理论解和数值解具有良好的一致性。现代计算资源允许计算流体动力学成为涡轮设计的一个组成部分。仿真结果证明，这种创新设计是可行的，具有潜在的应用前景。HBT实现了受控稳定平台与垂直钻具中执行器之间的“软”连接，可显着提高机械垂直钻具的控制精度。
