Description

新型泵的首级双吸叶轮
技术领域
本实用新型涉及一种叶轮结构。
背景技术
现行的多级泵吸入段叶轮结构包括首级叶轮和次级叶轮。其中首级叶轮采用两侧双吸,液体的流动是泵吸入口的液体分别流入双吸叶轮的两侧吸入口,经过双吸叶轮和进水端盖导入次级叶轮,完成吸入和增加液体能量的功能,其缺点是结构体积大、设计布置困难,组装拆卸困难,不方便维修。
实用新型内容
本实用新型针对上述缺陷,目的在于提供一种布置简单、组装拆卸方便的叶轮结构。
本实用新型的技术方案是:本实用新型包括多级叶轮,设置在泵轴上,首级叶轮采用双吸叶轮,其余级叶轮采用单吸叶轮,首级叶轮采用同侧双吸叶轮结构形式。
本实用新型的有益效果是:本实用新型具有体积小、结构紧凑、安装维修方便等特点。同时具有低汽蚀余量和高效率等优点,可广泛适用于多级离心泵的吸入段。
附图说明
附图为本实用新型的结构示意图
图中1为泵轴、2为双吸叶轮、3为单吸叶轮。
具体实施方式
本实用新型包括多级叶轮,设置在泵轴1上,首级叶轮采用双吸叶轮2,其余级叶轮采用单吸叶轮3,首级叶轮采用同侧双吸叶轮结构形式。
