一、 SH型单级双吸离心泵产品概述
双吸离心泵供抽吸清水或物理化学性质类似于水的其它液体之用。双吸离心泵目前主要分为SH型双吸离心泵和SOW型蜗壳式中开双吸离心泵两种。SH型双吸离心泵被输送液体温度不得高于80℃如果输送的温度更高可以选用SOW蜗壳式双吸离心泵。SH双吸泵适用于工厂、厂矿、城市给水、电站、农田排灌和各种水利工程。
二、SH型单级双吸离心泵结构说明
单级双吸泵的吸入口与吐出口均在水泵轴心线的下方，与轴线垂直成水平方向。检修时无需拆卸进出口水管及电机。从传动方向看去，离心泵为顺时针方向旋转（根据用户需要亦可改为逆时针方向旋转）。
双吸离心泵主要零件有：泵体、泵盖、叶轮、轴、双吸密封环、轴套等。
双吸离心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。水泵进出水法兰的下部，制有放水的管螺孔。
经过静平衡校验的叶轮，用轴套和两边的轴套螺母固定在轴上，其轴向位置可通过轴套螺母进行调整。
双吸离心泵轴由两个单列向心球轴承支承。轴承装在轴承体内、安装在泵体两端，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。
双吸离心泵通过弹性联轴器由电动机直接传动，必要时亦可用内燃机传动。
轴封为软填料密封（根据用户需要可采用机械密封结构）。
三、SH型双吸离心泵型号意义
例如：300S-58A
300-单级双吸离心泵入口直径（mm）
S型单级双吸离心泵
58-设计点扬程（m）
A-叶轮外径改变标志
