METHOD FOR DECREASING THE AMPLITUDE AND TIME OF THE PRESSURE FLUCTUATION IN PRESSURE PIPELINE FOR DELIVERING WATER TO TURBINES AND PUMPS

摘要

Device for reducing the amplitude and duration of pressure pulses in pressure pipes feeding water to water turbines and pump turbines operating in a block system, characterized in that the pressure pipes (1) of pump turbines (3) are connected together, in front of a cut-off fixture (2), by means of a connecting pipe (5) with a cut-off valve (6).IMAGE
