单级双吸中开泵概述
S型泵是取代Sh型单级双吸、卧式中开离心泵,供输送清水及物理化学性质类似于水的液体(液体高温度不超过80℃)。适合工厂、矿山、城市、电站的给排水,农田排涝灌溉和各种水利工程。SM、SF、SY型泵均是在S型泵基础上通过改变材质、密封、结构等措施而形成的分别适应于输送多泥砂水质或有耐磨要求、耐腐蚀要求或油类等介质。

1、S、SM、SF、SY型泵的吸入口与吐出口均在水泵轴心线下方,与轴线垂直呈水平方向,泵壳中开,检修时无需拆卸进水、排出管路及电动机(或其他动机)。从驱动端向泵的方向看,水泵均为顺时针方向旋转,根据需要也可生产为逆时针方向旋转,订货时应特殊提出。
2、S、SM、SF、SY型泵的主要零件有:泵体、泵盖、叶轮、轴、双吸密封环、轴套、轴承等。
3、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,残余轴向力则由轴端的轴承承受。
4、泵轴由两个单列向心球轴承或四个向心推力球轴承支承,轴承装在泵体两端的轴承体内,用黄油或稀油润滑。
5、水泵通过弹性套柱销联轴器由电动机直接驱动。
6、轴封为软填料密封,为了冷却润滑密封腔和防止空气进入泵内,在填料之间装有填料环,水泵工作时少量高压水通过泵盖中开面上的梯形凹槽或外部的不封管部件流入填料腔,起水封作用。

单级双吸中开泵结构图
1、本型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。
2、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。
3、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。
4、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。
5、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。
6、水泵通过联轴器由电动机直接传动。
7、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。
