这是一份描述关于简化灯泡式水轮发电机组进口设计对能量损失与流量分布的影响研究报告.灯泡式或全贯流式水轮发电机组的进水口尺寸与转轮直径相比是非常大的.由于进口断面流速很低,损失也很小.在布置方面利用水平的流道代替弯曲喇叭管进口,并缩短进口的长度,可有效地降低建筑物造价.另外,缩小进口尺寸将减小拦污栅、闸门和辅助操作设备的尺寸.
This is a study describing the impact of simplifying bulb design on the energy loss and flow distribution of a bulb turbine. The bulb size of the bulb or full-flow turbine is very large compared to the diameter of the rotor . Due to the low inlet flow velocity, the loss is also very small .In the layout of the level of the flow channel instead of bending the horn inlet, and shorten the length of the import, which can effectively reduce the cost of the building.In addition, reducing the size of the import will be reduced Trash, gate and auxiliary equipment dimensions.
