一、DF型锅炉给水泵产品概述:
DF型锅炉给水泵,供输送清水及物理化学性质类似于水的液体之用。本型水泵扬程在46至576米时,流量为6至55米/小时,液体的最高温度低于110适合于锅粮给水,轼厂及城市给水之用。水泵配用Y型电动机。目前所制造的DF型泵有:11/2D-5,21/2D6及4D8等共4种。 结构说明:DF型不锈钢水泵为多级分段式,其吸入口位于进水段上,吐出口在出水段上均垂直向上,其扬程机根据使用而增减水泵级数。水泵装配良好瑟否,对性能影响关系很大,万其是各个叶轮的出口与导叶进口之宁肯对位置,每级叶轮的吐出口中心必须对准导叶的中心,其中稍有偏差即将使水段上均直向上,其扬程可根据使用而增减水泵级数。水泵装配良好与否,对性能影响关系很大,尤其是各个叶轮的出口与导叶进口之相对位置,每级叶轮的吐出口中心必须对准导叶的中心,其中稍有偏差即将使水泵的流量减少,扬程降低,效率差,故在检修装配时务必注意,若有偏差必须调整。
