一种自吸泵
技术领域：
本发明涉及到一种泵，特别是涉及到一种自吸泵。
背景技术：
立式自吸泵广泛应用于电力、冶金、石化、采矿等行业， 现有的立式自吸泵流道进口流速不均匀，易形成涡带及由此引起的振动， 泵效率低，泵运行时产生的径向力、轴向力大，润滑装置散热效果不好， 成本高，大大降低了立式自吸泵的使用寿命。
发明内容：本发明的目的就是要提供一种自吸泵，它能很好 地克服目前立式自吸泵所存在的问题，本发明的目的是这样实现的， 一种自吸泵，是由进水段、吸水管、导水锥、喇叭管、首级泵体、轴 承座、滑动轴承等所组成，其特征在于：在首级泵体的外侧设置有进水段， 所述的进水段与吸水管相连，吸水管的另一端喇叭管设置在首级泵体的中 央，所述的喇叭管内设置有导水锥；喇叭管的上方设置有轴承座，轴承座 内设置有套在泵轴上的滑动轴承，由螺钉穿过轴承压盖对其密封，并对轴 承装置采用泵工作的自压液压循环润滑装置进行水润滑；泵轴的顶端分别 设置有首级叶轮和次级叶轮，所述的首级叶轮和次级叶轮采用反向对称设 置；所述的首级泵体的上段连接着次级泵体，首级泵体和次级泵体的水力设计采用双涡壳，并采用将首级泵体和次级泵体螺旋型压水室错开180度 的设置。本发明流道进口流速均匀，消除涡带及由此引起的振动，泵 效率高，能将泵运行时产生的径向力、轴向力减小到最低程度，润滑装置 散热效果好，大大提高了立式自吸泵的使用寿命。
