Abstract

本实用新型涉及一种单级单吸旋涡泵的泵盖。它包括泵盖,泵盖上设计有O形槽,O形槽内设有O形密封圈,泵盖的外圆法兰上设有三个丝孔和三个通孔。该泵盖能在叶轮磨损后,方便地进行轴向调整,使间隙达到设计要求,显著地延长了泵的使用寿命,(比普通泵盖可延长使用寿命3-5倍)且不需拆卸泵。

Description

一种单级单吸旋涡泵的泵盖
技术领域
本实用新型涉及一种单级单吸旋涡泵的泵盖。
背景技术
现有的旋涡泵的泵盖,存在一定的缺陷:该结构在泵使用一段时间后,叶轮与泵盖、泵体发生磨擦,轴向间隙增大,导致泵的流量、扬程降低、达不到工况要求,以致泵不能使用,需重新更换泵体、叶轮、泵盖,影响了正常生产,且维修费用昂贵。
发明内容
本实用新型的目的是针对现有技术存在的不足,提供一种能显著延长泵的使用寿命,且不需拆卸泵的单级单吸旋涡泵的泵盖
本实用新型的技术方案是:一种单级单吸旋涡泵的泵盖,包括泵盖,泵盖上设计有O形槽,O形槽内设有O形密封圈,泵盖的外圆法兰上设有三个丝孔和三个通孔。
本实用新型的优点是:1、能在叶轮磨损后,方便地进行轴向调整,使间隙达到设计要求,显著地延长了泵的使用寿命(比普通泵盖可延长使用寿命3-5倍);2、不需拆卸泵。
附图说明
图1是本实用新型一种旋涡泵部分剖视图
图2是本实用新型的一种旋涡泵的泵盖的剖视图
图3是本实用新型图2的A向视图
具体实施方式
如图1、图2、图3所示,一种单级单吸旋涡泵的泵盖,包括泵盖1,泵盖1上设计有O形槽6,O形槽6内设有O形密封圈9,泵盖1的外圆法兰上设有三个丝孔7和三个通孔8。
泵盖1与泵体3采用间隙配合(H7/f6)通过三个螺栓5联接,三个螺钉2旋入在泵盖1的丝孔7内;调节间隙的方法是,当叶轮4磨损而间隙增大后,停机,将泵盖1上的三个螺钉2旋松,然后拧紧螺栓6;这是泵盖1向前移动调到叶轮4与泵体3、泵盖1不发生磨擦后,再拧紧螺钉2,即可。
