Abstract：In order to obtain the maximum wall-attachment moment and decrease the friction force moment,an optimization design on fluidic component was made to ensure the normal running of the sprinkler.The driving and friction force moment of the sprinkler were analyzed.The driving moments of the sprinkler was arised from the jet offset impacting to the wall and the outlet cover board of the fluidic component.The friction resistance moment of the sprinkler was generated by the resistance between sections of hollow shaft,hollow shaft and its cover,and sealing set.The equation of center streamline of offset jet was deduced according to momentum equation.A formula to calculate the distance of attachment point and the angle of the attachment jet was also deduced.The relation between the maximum attaching moment and geometric parameters was obtained theoretically.The moment equation and rotating angle equation of fluidic sprinkler were also deduced.
