   河北鑫兴10sh-9双吸泵，离心泵结构说明
   
   sh系列单级双吸离心泵(中开泵)为单级、双吸、泵壳轴向中开的蜗壳式离心泵。泵吸入口与吐出口均在泵轴心线下方，呈水平方向。
   泵主要零件有泵体、泵盖、叶轮、轴、双吸密封环等。
   
   泵进出水法兰上，设有安装真空表和压力表的管螺孔，进出水法兰底部设有放水管螺孔。法兰按gb标准制作，也可采用iso、din、bs或ansi标准制作.叶轮经平衡校验合格后，用轴套及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。叶轮轴向力利用其叶片对称布置达到平衡。泵轴由两套滚动轴承支撑，安装在泵体两端。轴承采用油脂润滑。
   泵体上设有双吸密封环，拆卸更换方便。
   
   泵通过弹性柱销联轴器或金属迭片式联轴器由电动机直接传动。驱动机也可采用内燃机、气轮机。
   轴封可采用填料密封，也可采用机械密封。轴封冷却冲洗水可通过泵盖中开面上的凹槽进入轴封腔，也可通过外接冷却水管进入轴封腔。
