S、SH型中开双吸泵
S、SH型中开双吸泵的性能及优点
中开双吸泵的吸入口和吐出口均在水泵的轴心线下方,与轴线垂直成水平方向。维修方便,无须拆卸进、出水管路及电动机,高效节能、应用范围广。
S型单级双吸水平中开式离心泵是新型节能卧式中开泵,主要由泵体、泵盖、轴、叶轮、密封环、轴套、轴承部件等组成,其吸入口和排出口均在水泵轴心线下方,检修时,只要将泵盖揭开,即可将全部零件拆下进行维修。供输送清水或物理化学性质类似水的其它液体,根据用户需求,通过改变泵结构及材质可用于输送多泥沙水或各类腐蚀性液体。其性能符合JB/1050-93《单吸双吸清水离心泵型式与基本参数》标准。
S、SH中开双吸泵的应用范围
适用于工厂、矿山、城市给水、电站、自来水、农田灌溉和各种水利工程。
