一、 概述
SH型泵系单级、双吸、泵壳中开式离心泵。供吸送清水及物理化学性质类似于水的液体。
本型泵扬程在9米至140米时，流量为126米3/时至12500米3/时。液体最高温度不得超过80℃。适用于工厂、矿山、城市给水、电站、大型水利工程、农田灌溉和排涝等用，48SH－22型大型泵还可作热电站循环泵用。
泵型号的意义：如10SH－13A…
10－吸水口直径被25除（即该泵吸水口直径为250毫米）。
SH－单级双吸卧式离心清水泵
13－比转数被10除（即该泵的比转数为130）
A…表示该泵换了不同外径的叶轮。
S型泵流量范围更广：50－18000米3/时。如500S35A…
500－泵的吸入口径（mm）
S－单级双吸、中心离心清水泵
35－设计点扬程（m）
A…－叶轮第一…次切割
SH型泵及S型泵统称为双吸泵，其工作性能及配用电机大体相同。需要说明的是泵的旋转方向不同，从电机端看SH型泵为逆时针旋转，而S型泵则顺时针。在实际使用中SH型泵更加广泛，故以下介绍以SH型泵为主。
二、 结构说明
SH型泵的吸入口与吐出口均在水泵轴心线下方，成水平方向，与轴线成垂直位置。水泵泵盖用双头螺栓及圆锥定位螺钉固定在泵体上，可以便于揭开检查水泵内全部零件，无需拆卸进水，排出管路及电动机，因此检修极为方便。
SH型泵主要零件有：泵体、泵盖、叶轮、轴、双吸密封环、轴套、轴承体。
泵体：铸铁制成。与泵盖构成叶轮的工作室，进、出水通道的法兰上制有安装真空表和压力表的管螺孔。管颈最低处制有放水的管螺孔。
泵盖：铸铁制成。在上部制有安装水封管及入气管的管螺孔和起吊泵盖的钓钩。
叶轮：铸铁制成。其形状是对称的，在两壁间有扭曲的叶片。液体从两侧面进入叶轮。制造时，经过静平衡试验。
轴：优质炭素钢制成。轴的中央是叶轮，用键、轴套和两边的轴套螺母固定。轴的右端是安装联轴器的，与电动机直接联接。在联轴器端不允许用皮带传送，若需用皮带传动时，必须另设支架支持皮带轮。
双吸密封环：铸铁制成。防止水泵中高压水漏回进水部分。在双吸密封环上制有突起的半圆款环，嵌在泵体内，用来固定双吸密封环。为易损零件，可多备件以便更换。
轴套：铸铁制成。用作固定叶轮位置及保护填料室内轴的磨损，亦为易损零件应多备件。
SH型泵有两个支撑、使用单列向心球轴承，装在轴承体内靠近联轴器一端的统称轴承体甲部件，另一端称轴承体乙部件，用黄油润滑。由于叶轮是完全对称的，在理论上水泵不产生轴向力，但在制造上很难做到水泵两侧的水流通过部分及密封环处间隙完全一样，因此水泵有轴向力产生的可能，产生的轴向力及振动力由轴承部件中的单列向心球轴承承受。
填料起着密封的作用，防止空气透入泵内和大量液体的渗出，填料密封由泵体和泵盖合成的填料室、填料压盖、填料环、填料套及填料组成。泵盖内少量高压水通过外部水封管（或内部水槽）及填料环流入填料室中，起水封冷却作用。
填料的松紧程度必须适当，不可太紧或太松，以液体能够逐滴渗出为准，填料太紧，轴承易热，同时耗费功率；填料太松，液体渗漏大，都要降低水泵效率。
