Abstract
In response to the problem of excessive mutual influence of water hammer pressures in dif-ferent valve branches during the operation of a multi-valve fuel delivery pipeline system,taking into ac-count the constraints of fast response requirements,lightweight and compact structure of the system,the water hammer characteristics of the pipeline under complex working conditions of multiple valves were studied through experiments.The relationship between the changes in water hammer pressure in the pipeline and the pulse working mode of the valve,as well as the combination of valves working si-multaneously,were researched.The relationship between water hammer pressure and the time interval between valve opening and closing,as well as the relationship between valve control cycle and the number of valves working simultaneously had also been deeply studied.Based on this,a water hammer suppression measure based on multi-valve working mode adjustment was proposed.The research results indicate that it is feasible to reduce water hammer pressure in the fuel delivery pipeline without increa-sing system complexity and weight.关键词
