Description

分段式多级高扬程潜水泵
技术领域：
本实用新型涉及潜水泵技术领域，尤其涉及一种分段式多级高扬程潜水泵。 
背景技术：
市场上使用的高扬程潜水泵，均采用泵轴穿过多级叶轮及导流部件，在其首级与末级之间采用螺杆（螺栓）或类似部件压紧，从而完成产品总装。由于高扬程泵级数多、高度高，且金属材料具有塑性，压紧过程中材料会拉伸延展，压紧力不足，在工况压力下，该结构的压紧方式会造成各级导流部件之间泄漏，潜水泵出水口压力不能满足工作要求，若不及时发现，冲刷井壁，会造成井内塌方，致使机井报废；此外高扬程潜水泵叶轮级数较多，泵轴均为细长轴，工作时叶轮产生的离心力，易造成泵轴弯曲，产生偏磨、卡滞现象。 
发明内容：
本实用新型解决的技术问题：设计一种分段式多级高扬程潜水泵，采用分段式安装结构，通过分段外壳两端的螺纹压紧，压紧更可靠，安装效率更高，防渗漏性能更佳。 
本实用新型的技术解决方案：一种分段式多级高扬程潜水泵，由进水节、分段外壳、轴承体及止逆阀体依次螺纹密封连接而成，泵轴通过橡胶轴承轴向安装在进水节及轴承体的中央，所述分段外壳内的泵轴上安装有叶轮总成；所述泵轴最下端装有联轴器。 
所述上、下级叶轮总成之间通过套装在泵轴上的轴套Ⅰ定位，且在泵轴的末端通过螺母压紧轴套，进而压紧各级叶轮总成，限制各级叶轮总成的轴向位移。 
所述所述叶轮总成由2-3级叶轮和导叶组成，且上、下级叶轮之间通过套装在泵轴上的轴套Ⅱ定位，上、下级导叶之间通过套装在泵轴上的支承体定位。 
本实用新型与现有技术相比具有的优点和效果： 
1、采用分段式安装结构，通过分段外壳两端的螺纹压紧，压紧更可靠，安装效率更高，防渗漏性能更佳。 
2、每个分段内装有多级叶轮及导流部件，泵轴穿过叶轮安装于各级导流部件中，各级导流部件之间平面接触，没有配合精度要求，加工简单。 
3、每个分段内多级叶轮之间安装有支承体部件，增加了长泵轴支承点数量，能有效防止叶轮偏磨、卡滞故障的发生，提高了高扬程潜水泵工作的可靠性。 
附图说明
图1为本实用新型的结构示意图。 
具体实施方式
下面结合附图1描述本实用新型的一种实施例。 
一种分段式多级高扬程潜水泵，由进水节1、分段外壳2、轴承体3及止逆阀体4依次螺纹密封连接而成，泵轴5通过橡胶轴承6轴向安装在进水节1及轴承体3的中央，所述分段外壳2内的泵轴5上 安装有叶轮总成7；所述泵轴5最下端装有联轴器13。所述上、下级叶轮总成7之间通过套装在泵轴5上的轴套Ⅰ8定位，且在泵轴5的末端通过螺母压紧轴套Ⅰ8，进而压紧各级叶轮总成7，限制各级叶轮总成7的轴向位移。所述所述叶轮总成7由2-3级叶轮9和导叶10组成，且上、下级叶轮9之间通过套装在泵轴5上的轴套Ⅱ11定位，上、下级导叶10之间通过套装在泵轴5上的支承体12定位。 
本实用新型根据扬程确定分段安装节数和叶轮级数，安装完成后通过联轴器13与潜水电机联接即可。 
上述实施例，只是本实用新型的较佳实施例，并非用来限制本实用新型实施范围，故凡以本实用新型权利要求所述内容所做的等同变化，均应包括在本实用新型权利要求范围之内。
