Abstract

本实用新型涉及一种新型立式无密封自控自吸泵。包括电机、进水管、出水管、吸水室、泵体、叶轮、泵轴、副叶轮、支架、停车密封、导叶盖板,其特征在于:泵轴连接叶轮,在叶轮的轮毂相对处有导叶后盖板,导叶后盖板与导叶盖板为间隙配合。本实用新型的优点是密封住了压水室的液体泄漏,从而减小了泵的容积损失,提升水泵效率。由于去除了滑动轴承,即去除了易损件,降低了水泵维护成本。

Description

一种新型立式无密封自控自吸泵
技术领域
本实用新型涉及一种自吸泵,特别是一种新型立式无密封自控自吸泵。
背景技术
目前国内立式无密封自控自吸泵结构,主要由进水管、吸水室、泵体、叶轮、轴、轴套、水导轴承、轴承座、副叶轮、支架、停车密封等组成。该结构存在以下缺陷:由于采用了水导轴承,即滑动轴承,则不适用于输送含固体颗粒浓度较大的液体,如污水、含铁屑水、含结晶液体等介质。泵效率低。叶轮空置于泵腔中,容积损失较大,泵组效率低。
发明内容
本实用新型的目的是解决现有技术中立式无密封自控自吸泵因采用水导轴承所存在的上述问题,提供一种新型立式无密封自控自吸泵。本实用新型设计一种新型立式无密封自控自吸泵,包括电机、进水管、出水管、吸水室、泵体、叶轮、泵轴、副叶轮、支架、停车密封、导叶盖板,其特征在于:泵轴连接叶轮,在叶轮的轮毂相对处有导叶后盖板,导叶后盖板与导叶盖板为间隙配合。本实用新型的优点是密封住了压水室的液体泄漏,从而减小了泵的容积损失,提升水泵效率。由于去除了滑动轴承,即去除了易损件,降低了水泵维护成本。
附图说明
下面结合附图和实施例对本实用新型作详细说明,
附图为本实用新型的结构示意图,
具体实施方式
图中包括电机1、进水管2、出水管3、吸水室4、泵体5、叶轮6、泵轴7、副叶轮8、支架9、停车密封10、导叶盖板11,其特征在于:泵轴7连接叶轮6,在叶轮6的轮毂相对处有导叶后盖板12,导叶后盖板12与导叶盖板11为间隙配合,增设导叶后盖板12结构,导叶后盖板12与导叶盖板11为间隙配合、与叶轮6轮毂间隙很小。这样就密封住了压水室的液体泄漏,从而减小了泵的容积损失,提升水泵效率。由于去除了滑动轴承,即去除了易损件,降低了水泵维护成本。
