Improving the pneumatic actuator of the locomotive sand feeding system by increasing the outlet flow velocity

Abstract

During the study, the main characteristics and parameters of the gas jet injector of the pneumatic actuator for the locomotive sand feeding system were calculated based on the specified input and output values of gas flows. The process of ejecting an additional volume of ambient air in order to increase the outlet flow velocity of the air-sand mixture from the outlet pipe of the locomotive sand feeding system was simulated by means of the FlowSimulation package tools of the SolidWorks CFD software for solid modeling. The reduction in the compressed air consumption relative to the standard locomotive sand feeding systems has been achieved.
