| Abstract: | Based on the results of prototype and model tests of three locks, the hydraulics characteristics of the filling and emptying system,hawser force,and valve hydraulics which includes culvert pressure, cavitation number,operating load of valve and valve vibration, are analyzed and compared. As shown in this paper, there is a differece in hydraulic characteristics between the prototype and the model of the three locks. The chambers are filled and emptied faster in prototype than in model. The average pressure downstream from valve of the prototype is 20-30kPa lower than that of the model. This paper is for reference of researchers and designers. |
