S.SH系列泵单级.双吸.泵壳水平中心开式离心泵。供输送清水及理化性质类似是
的液体之用，介质温度不高于80度，若两端轴承通似冷却水，介质温度可达130度。改变叶轮.机封环和轴套的材料，可以汲送含有泥沙的浑水。绷得轴封一般采用软填料，如有特殊定货要求，也可装机械密封。
双吸泵作为离心泵的一种重要形式，因其具有扬程高、流量大等特点，在工程中得到广泛应用。这种泵型的叶轮实际上由两个背靠背的叶轮组合而成，从叶轮流出的水流汇入一个蜗壳中。双吸泵具有如下一些特点：它相当于两个相同直径的单吸叶轮同时工作，在同样的叶轮外径下流量可增大一倍；泵壳水平中开，检查和维修方便，同时，双吸泵进出口在同一方向上且垂直于泵轴，利于泵和进出水管的布置与安装；双吸泵的叶轮结构对称，没有轴向力，运行较平稳。在我国黄河沿线地区提灌泵站流量较大、扬程都较高，大多采用双吸离心泵。南水北调中线惠南庄泵站也采用了双吸泵进行供水。
产品简介
SH型双吸清水离心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，水泵均为逆时针方向旋转。如根据用户特殊订货需要也可改为顺时针旋转。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，进出水法兰的下吝降制有放水的管螺孔。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，水泵工作时少量高压水通过水封管流入填料腔起水封作用。
