摘  要:闡述了一種雙螺旋擺動結(jié)構(gòu)的工作原理和力學(xué)性能。比較分析了常見轉(zhuǎn)槳式水輪機(jī)和雙螺旋擺動結(jié)構(gòu)的轉(zhuǎn)槳式水輪機(jī),提出了“單獨(dú)控制、協(xié)同工作”的同步精確控制葉片轉(zhuǎn)角方法。通過某電站實(shí)際工況,計(jì)算并驗(yàn)證了該結(jié)構(gòu)在轉(zhuǎn)槳式水輪機(jī)上應(yīng)用的可行性。

關(guān)鍵詞:雙螺旋擺動結(jié)構(gòu);轉(zhuǎn)槳式水輪機(jī);葉片轉(zhuǎn)角調(diào)整

Abstract: The working principle and mechanical properties of a double helix swing structure are described. In this paper, the common Kaplan turbine and the Kaplan turbine with double helix swing structure are compared and analyzed, and the synchronous and accurate blade angle control method of "separate control and cooperation" is put forward. Through the actual working conditions of a power station, the feasibility of the application of the structure to Kaplan turbine is calculated and verified.

Keywords: double helix swing structure; Kaplan turbine; blade angle adjustment
