Among them, the runner of the impingement turbine is rotated by the impact of the water flow, and the pressure of the water flow does not change during the working process, which mainly realizes the conversion of kinetic energy. The impact turbine can be divided into two types according to the flow direction of the water flow: the cutting type (also known as the bucket type) and the oblique type; the structure of the oblique turbine and the bucket turbine is basically the same, but the direction of the jet of the oblique turbine Has an inclination and is only used for small units.
反击式水轮机的转轮是在水中受到水流的反作用力而旋转，在工作过程中水流的压力能和动能均有改变，但主要是压力能的转换。反击式水轮机可分为混流式、轴流式、斜流式和贯流式。在混流式水轮机中，水流径向进入导水机构，轴向流出转轮；在轴流式水轮机中，水流径向进入导叶，轴向进入和流出转轮，；在斜流式水轮机中，水流径向进入导叶而以倾斜于主轴某一角度的方向流进转轮，或以倾斜于主轴的方向流进导叶和转轮；在贯流式水轮机中，水流沿轴向流进导叶和转轮。此外，轴流式、贯流式和斜流式水轮机按其结构还可分为定桨式和转桨式。定桨式的转轮叶片是固定的；转桨式的转轮叶片可以在运行中绕叶片轴转动，以适应水头和负荷的变化。The runner of the impact turbine is rotated by the reaction force of the water flow in the water. During the working process, the pressure energy and kinetic energy of the water flow are changed, but the main point is the conversion of pressure energy. The impact turbine can be divided into Francis flow, axial flow, oblique flow and tubular flow. In a Francis turbine, the water flow enters the water guiding mechanism radially, and flows out of the runner axially; in an axial-flow turbine, the water flow enters the guide vane radially, and enters and exits the runner axially; in a diagonal-flow turbine, The water flow enters the guide vane radially and flows into the runner at an angle inclined to the main shaft, or flows into the guide vane and runner in a direction inclined to the main shaft; in a tubular turbine, the water flow flows into the guide along the axial direction. Leaf and runner. In addition, axial-flow, tubular and oblique-flow turbines can also be classified into fixed-blade and rotating-blade turbines according to their structure. The fixed-paddle runner blades are fixed; the rotary-paddle runner blades can rotate around the blade axis during operation to adapt to changes in water head and load.
然而，在这些现有的水力发电机中，不同类型的水力发电机需在不同的水流情况下才能取得较好的发电效率；例如，冲击式水轮机适用于高水位小水压的情况；混流式水轮机适用于高水位大流量的情况；贯流式水轮机适用于低水位大流量的情况。另外，现有水轮机都有一定的漏水率，从而降低了水轮机的效率。因此，开发一种能适用于各种水位和流量且结构简单效率高的水轮机就成了亟需解决的问题。However, among these existing hydroelectric generators, different types of hydroelectric generators need to obtain better power generation efficiency under different water flow conditions; for example, impulse turbines are suitable for high water level and small water pressure; Francis flow The hydraulic turbine is suitable for the situation of high water level and large flow; the tubular turbine is suitable for the situation of low water level and large flow. In addition, the existing water turbines have a certain water leakage rate, thereby reducing the efficiency of the water turbine. Therefore, it is an urgent problem to develop a water turbine with a simple structure and high efficiency that can be applied to various water levels and flow rates.
