摘要
通过在龙抬头上两个平直段部位 (上弯段与斜向直线段 )分别设置孔板及偏心孔板 ,进行流态、压力、流速等项观测 ,并对消能系数和水流空化数做分析计算 。
After the separate installation of orifice plate and partial orifice plate on the two flat and straight part in Longtaitou, the writers made observations on flowform, pressure, flow rate, etc. and then analyzed and calculated the energy_dissapation coefficient and water cavitation number. Thus, the tentative conclusion, which the orifice plate isn't suited for the Longtaitou, is proved.
