  ①坚持电扇的一般任务机能。风冷柴油机完整依托电扇产生的壮大气流来冷却机体。有的机型(如fl912/913系列柴油机)经由进程电扇胶带来驱动电扇高速扭转,固然设有张紧滚轮,但若是张紧弹簧的弹力缺乏,也会呈现胶带跳动、拓滑致使冷却效力降落的结果。应实时调剂,以胶带中部属沉量至10-15mm为好。有的机型(如8f8l413f型柴油机和俄制t-330型推土机上的b-400型风冷柴油机)无电扇胶带,其电扇的驱能源来自液力巧合器,是以可按照机温的凹凸增减机油流量,以对巧合器停止调理来转变电扇转速,到达主动节制风量的目标。这类冷却系的排时令温器和油压调剂螺钉在柴油机出厂前已调好,操纵或颐养机械时不可随便调剂。如有毛病,应由谙练技工检验。
