Description

对角叶片泵
技术领域
本实用新型涉及一种泵，具体涉及一种对角叶片泵。
背景技术
泵广泛应用于农田灌溉，抗旱排涝、南水北调等使用领域，现有的低扬程叶片泵，水泵的效率受到水泵流道的限制，普谝不高，因而在各领域使用的经济效益受到限制。
发明内容
本实用新型的目的是为了克服现有技术的不足，提供一种高效率对角叶片泵。
本实用新型的技术方案是：一种对角叶片泵，包括主轴、水导轴承、转轮和导叶体，所述转轮由叶片和转轮体组成，转轮体安装在主轴上，主轴套入水导轴承中，水导轴承安装于导叶体中心，所述叶片采用对角布置，即叶片轴线与主轴中心线成70-85度的夹角。
所述转轮体的形状最好采用锥体形，可以与叶片的对角布置相适应，所述导叶体的内流道壁最好采用与转轮体相匹配的锥体形状，使得流道设置更加合理，所述叶片的角度最好可以调节，通过调节可以改变叶片的安放角，使之效率更宽。
本实用新型可以适用于低扬程立式泵，也可以适用于贯流式泵。
有益效果：本实用新型极大的改善了水泵中水的流态，减小了水力损失，提高了水泵效率，而且高效率区范围宽。
附图说明
附图为本实用新型具体实施方式的结构示意图。
具体实施方式
