摘要
一般情况,工作闸门采用弧门,无门槽空化问题,但有的工程由于其它条件限制,而采用平板工作闸门,其门槽空化特性需要深入研究。本文结合积石峡水电站中孔泄洪洞,通过减压模型试验对平板工作闸门槽的空化特性进行了研究。利用空化噪声测量,分析了不同运行水位和不同闸门开度时,门槽体型的空化特性。试验结果表明,该工作闸门槽体型的空化特性良好,可以满足工程运行的需要。
Generally, there is without problem of gate slots cavitation when arch gate is used as the working gate, however, urder some restrictive conditions, the flat gate is used as the working gate in middle outlet in Jishixia hydropower station. The cavitation characteristic of working gate slot is studied by the decompression model test. By means of acoustics method, the flat working gate slots cavitation characteristic is studied at different water level with different gate opening. The test results indicate that the working gate slot hasn＇t cavitation and it can be put into operation.
