SDS-5.6隧道射流风机发生列车火灾工况或阻塞工况时,根据列车及火源的位置,配合区间隧道风机进行正转或反转,进行气流组织。正常工况运行时, 风机能满足环境温度不超过45℃,相对湿度不超过95%的条件下,每天连续正常运行。火灾工况时,能满足在150℃条件下连续有效运行1h。风机在14s 内应能从启动达到额定转速,从正转到反转或从反转到正转的切换时间均不大于60s。
机壳与动叶轮的径向单侧间隙应在叶轮直径的0.15%~0.35%范围内,但蕞小值不小于2mm,同一台风机的间隙应均匀,任意两处间隙值相差不超过20%。
SDS-5.6隧道射流风机设置在隧道内,悬挂安装在隧道顶部,要求风机结构紧凑,且风机整体设计应考虑风机的拆卸维修,连接管式消声器、基础固定螺栓均可灵活拆卸;同时,不应影响风机的防振、防松要求。风机表面应清洁、平整、无碰伤、划痕及锈斑;漆层牢固、色泽均匀*,无起泡、缩皱和剥落现象。焊接应牢固,焊缝应光洁均匀,焊缝不得有砂眼,焊渣应去净。
可逆转射流风机包括风机本体、叶轮、内置式电机、接线盒、注排油装置、整流罩、两端管式消声器(每端管式消声器长度为2D)、必要的连接紧固件等组成。可逆转射流风机安装在区间隧道顶板下方,为方便安装并防止和减少风机振动影响,风机出厂时除风机本体和消声器外,还包括减振器、紧固件和吊装支架等。
