Description

液体泵
技术领域
本发明涉及泵类,详细讲是一种液体泵。
背景技术
我们知道,现有的液体泵,在泵体内设有泵轴,泵轴前端设有叶轮,与叶轮轮毂相对应泵体内壁上设有密封环,密封环与泵体为一体铸造。这种液体泵,工作时,液体内的杂质与叶轮和密封环相互摩擦,磨损密封环,密封环与叶轮的间隙越来越大,泵的效率逐渐下降,使用一定时间后,需要更换密封环,由于密封环与泵体为一体铸造,只能更换整个泵体,泵体使用寿命短,维修、使用成本高。
发明内容
本发明解决的技术问题是,解决泵体使用寿命短,维修、使用成本高的问题,提供一种泵体使用寿命长,维修、使用成本低的液体泵。
本发明的技术方案是,泵体内设有泵轴,泵轴前端设有叶轮,与叶轮的轮毂相对应泵体内壁上设有密封环,主要结构特点是,密封环与泵体分体铸造,密封环通过过盈配合安装在泵体上。
本发明的有益效果是,由于密封环与泵体分体铸造,密封环通过过盈配合安装在泵体上,当使用一定时间密封环磨损严重时,只要单独更换密封环即可,泵体使用寿命长,维修、使用成本低。本发明适用于液体泵。
附图说明
附图是本发明的一种结构示意图,也是一种实施例的示意图。
具体实施方式
如图所示的液体泵,泵体2内设有泵轴4,泵轴4前端设有叶轮1,与叶轮1的轮毂5相对应泵体2内壁上设有密封环3,密封环3与泵体2分体铸造,密封环3通过过盈配合安装在泵体2上,由于密封环3与泵体2分体铸造,密封环3通过过盈配合安装在泵体2上,当使用一定时间密封环3磨损严重时,只要单独更换密封3环即可,泵体2使用寿命长,维修、使用成本低。
