Abstract

L'invention concerne un véhicule ferroviaire et un système de pulvérisation de sable associé. Le système de pulvérisation de sable comprend des pulvérisateurs de sable (7) disposés au niveau d'essieux dans un bogie de véhicule. Un module de commande de pulvérisation de sable (5) est relié à chaque pulvérisateur de sable (7). Chaque module de commande (5) commande le fonctionnement d'un seul pulvérisateur de sable (7). Le module de commande de pulvérisation de sable (5) comprend un ensemble soupape de commande. Le pulvérisateur de sable (7) est en communication avec une source de gaz au moyen de l'ensemble soupape de commande. Le module de commande de pulvérisation de sable (5) est prévu indépendamment sur chaque pulvérisateur de sable (7) disposé au niveau de l'essieu. Chaque pulvérisateur de sable (7) est commandé indépendamment par l'ensemble soupape de commande dans le module de commande de pulvérisation de sable (5). Différents modules de commande (5) sont également utilisés pour des pulvérisateurs de sable (7) qui doivent effectuer la même fonction sur des différents essieux, de telle sorte que le travail de chaque pulvérisateur de sable (7) est efficacement garanti, c'est-à-dire que l'indépendance d'un pipeline est commandée, et l'influence mutuelle entre différents pulvérisateurs de sable (7) provoquée par la communication d'une structure de pipeline est empêchée. De plus, l'indépendance de la structure de pipeline garantit que la quantité de déchargement de sable du pulvérisateur de sable (7) sur un certain essieu peut être particulièrement réglée sans altérer les autres pulvérisateurs de sable environnants (7).
