Abstract

一种自吸泵吸入箱体,涉及自吸泵领域。它是在泵体内侧设吸入箱体,箱体内设竖直装置逆止阀,箱体分别与泵吸入管路和泵叶轮进口连接。泵停机时,泵和吸入管路内的液体均能得以保存,泵再次启动时,可以快速实现自吸功能。

Description

一种自吸泵吸入箱体
一、技术领域
本实用新型涉及一种自吸泵吸入箱体,用于自吸泵,尤其适用于立式自吸泵。
二、技术背景
通常的立式自吸泵,为了在停泵时存住泵内的液体,在进口处装水平放置的逆止阀(拍门),在或安装电磁阀,泵停机时切断虹吸,以防泵内液体倒流至吸入池,这些措施存在很多不足,最大缺点是可靠性差,容易出现故障,使自吸功能失效。
三、发明内容
本实用新型提出一种自吸泵吸入箱体,它是在泵体内设吸入箱体,吸入箱体的侧面或下面与泵的吸入管连接,另与泵叶轮进口相连接,箱体内竖直方向安装逆止阀。具有工作可靠,同步吸排(开机出水)的功能。
本实用新型的目的是这样实现的:立式自吸泵由叶轮、压水室(蜗室或导叶),轴和含吸入箱体的泵体等组成。泵运行时,液体从吸入管进入吸入箱体,通过逆止阀进入泵叶轮经压水室排出。泵停机时,液体倒流,逆止阀关闭,逆止阀出水侧连同泵内液体得以保存,逆止阀进口侧的液体,由于液体倒流形成的空位(真空)而被吸引住,这样吸入管路内也有液体。由于泵内和吸入管内都有液体,泵一开机便可出水,开始正常工作了。
四、附图说明
下面结合附图对本实用新型进一步说明
图1是本实用新型结构的示意图
叶轮1,压水室2,泵轴3,吸入箱体4,逆止阀5,吸入管6,泵体7。
五、具体实施方案
如图所示,启动泵,液体经吸入管6进入吸入箱体4,经逆止阀5流到叶轮1进口,从压水室2排出。泵停机时,液体倒流,逆止阀5关闭,泵体7和吸入管6内的液体得以保存,供下次启动泵时快速完成实现自吸。
