一、产品概述: s、sh型单级双吸泵壳中开之离心泵(s型中开泵),供抽送清水或物理化学性质类似于水的其它液体之用。被输送液体温度不得高于80℃。适用于工厂、矿山、城市给水、电站、农田排灌和各种水利工程。
二、s型中开泵结构图:
s型中开泵的吸入口与吐出口均在水泵轴心线下方,水平方向与轴线成垂直位置、泵壳.中开,检修时无需拆卸进水,排出管路及电动机(或其他原动机)从联轴器向泵的方向看去,水泵均为逆吋针方向旋转。如根据用户特殊订货需要也可改为顺吋针旋转。本型泵的主要另件有:泵体、泵盖、叶轮、轴、双吸密封环、轴套、轴承等。除轴的材料为优质碳素钢外,其馀多为铸铁制成。泵体与泵盖构成叶轮的工作室,在进出水法兰上制有安装真空表和压力表的管螺孔,进出水法兰的下部制有放水的管螺孔。叶轮经过静平衡校验,用轴套和两侧的轴套螺母固定,其轴向位置可以通过轴套螺母进行调整,叶轮的轴向力利用其叶片的对称布置达到平衡,可能还有一些剩馀轴向力则同轴端的轴承承受。泵轴由两个单列向心球轴承支承,轴承装在泵体两端的轴承体内,用黄油润滑,双吸密封环用以减少水泵压水室的水漏回吸水室。水泵通过联轴器由电动机直接传动。轴封为软填料密封,为了冷却润滑密封腔和防止空气漏入泵内,在填料之间有水封环,水泵工作时小量高压水通过水封管流入填料腔起水封作用。
