The invention relates to a novel vortex elimination measure for high-speed water flow in a water jet propulsion pump device, hub vortex can be monitored and judged through a real-time pressure sensor, and a plurality of flow guide pipes arranged on the surface of a water guide cone are dynamically controlled through an electromagnet, so that the tails of the arc-shaped flow guide pipes enter the edge of a low-pressure area of the hub vortex; water flow is accelerated by means of pressure difference between the head end and the tail end of the arc-shaped flow guide pipe to form high-speed water flow to disperse hub vortexes. On the other hand, the arc-shaped flow guide pipe enables internal water to have vorticity opposite to hub vortex rotation, and the internal structure of the hub vortex is further collapsed. Therefore, generation and evolution of hub vortexes are effectively restrained, stability of a tail flow field of the water jet propulsion pump device is improved, and propulsion efficiency and operation stability of the pump device are guaranteed.
本发明涉及一种借助喷水推进泵装置内部高速水流的新型消涡措施,可通过实时压力传感器监测判断毂涡的发生,通过电磁铁动态控制导水锥表面布置的多个导流管,使得弧形导流管尾部进入毂涡低压区边缘,借助弧形导流管首尾端压力差对水流进行加速,形成高速水流冲散毂涡。另一方面弧形导流管使得内部水体带有与毂涡旋转相反的涡量,进一步瓦解毂涡内部结构。从而有效抑制毂涡的发生及演化,提高喷水推进泵装置尾部流场稳定性,保证泵装置推进效率以及运行稳定。
