Structural Design and Parameter Influence Study on Vibration Damping of Rotating Distributor Disk for Alternating Flow Distribution Pump
In order to solve the problem of severe vibration of the pump due to the larger pulsations of the output flow caused by the continuous change of the relative phase between the plunger and the rotating disk,a triangular damping groove-type rotatingdistributor disk vibration damping structure was designed.The vibration damping structure overflow area model was established,and the simulation model of the alternating flow distribution pump containing the rotating distributor disk vibration damping structure was built by using AMESim.Based on the simulation model,the influence of structural parameters such as depth angle,width angle and circumferentialangle ofthe triangular groove on the flow pulsation was analyzed,and the optimal scheme of the rotating distributor disk vibration damping structure of the alternating flow distribution pump was formed.The results show that the addition of a triangular damping groove in the transition region of the rotating distributor disk can significantly reduce the flow pulsation,and the pulsation rate of the alternating flow distribution pumpis 31.4%with the triangular groove circumferential angle of 21°,the width angle of 100°,and the depth angle of 16°.The study provides a reference for the design and parameter selection of the vibration damping structure of the rotating distributor disk of the alternating flow distribution pump.
