含沙水水轮机导水部件模型实验装置

Model Test Equipment of the Wicket-Gate of Water Turbine in the Silt Carrying Flow

叙述了新研制的含沙水水轮机导水部件模型实验装置的设计、功能及测试方法。该装置简单、功能多,可用于水轮机引水、导水部件的流场研究与方案对比,也可用于含沙水流在管路及阀门中的流动及水泵工作特性研究;提出的含沙水时流场测压的内外平衡法,解决了测压孔易堵塞的难题。

This paper recounts the design, function and measuring method of newly manufactured model test equopment for the wicket-gate of water turbine in silt carrying flow. The equipment is simple intuitional and with multiple functions, and it may be used to not only investigate the flow field and scheme comparison of the wicket-gate, but also analyse the flow characteristic of the silt earring flow in pipeline, valve and pump. The balance method, inside and ourside, of measuring pressure in the flow field has been developed with an advantage to be able to solve the stoppage problem of the pressure measuring holes.
