Abstract

本发明公开了一种变速水轮泵,属农业灌溉机械技术领域,所述变速水轮泵主要由水轮机、增速器和水泵组成,它可以在低落差水位下正常运行,还可通过改变增速器的传动比获得不同的扬程,以适应水利工程的需要,本发明扩大了水轮泵的使用范围。

Description

变速水轮泵
技术领域
本发明涉及农业灌溉技术领域,尤其是一种可变速的水轮泵。
背景技术
目前生产和使用的水轮泵是由水轮机跟水泵同轴安装组合成的,是不可变速的,当水落差低时,水轮泵转速变低,扬程也变低,效率也低,有时还抽不上水耒。
发明内容
本发明要解决的问题是提供一种低落差水位也能正常运行的变速水轮泵。
为解决上述问题,本发明采用的方案是:水轮机通过一个增速器来传动水泵高速运转来提高扬程,水轮机和水泵不再是同轴安装。
由于采用上述方案,本发明有如下有益效果:
1.水轮泵在低落差水位也能正常运行,扩大了水轮泵的使用范围。
2.通过改变增速器的传动比可获得不同的扬程,可适应不同水利工程的需要。
附图说明
说明书附图是本发明的结构示意图。
具体实施方式
以下结合附图实例对本发明的结构作进一步说明:
在附图所示的结构中,水轮机1的轴与增速器2的输入轴相连接,增速器2的输出轴与水泵3的轴相连接,水轮机1通过增速器2传动水泵3。
