Abstract

一种风机进风口密封装置,涉及离心式风机密封装置的技术领域。本发明包括进风口、叶轮,进风口与叶轮相对布置,靠近叶轮一侧的进风口上设置凸出装置。本发明实现了结构简单,密封效果好,提高风机效率的目的。

Description

一种风机进风口密封装置
技术领域
本发明涉及离心式风机密封装置的技术领域。
背景技术
风机的机壳上布置有进风口,叶轮布置在机壳内部,通常为了减少回流损失,采用减少进风口与叶轮之间的间隙,但是不能碰撞到叶轮,对加工工艺要求较高,且不易操作。
发明内容
本发明目的是提供一种结构简单,密封效果好,提高风机效率的风机进风口密封装置。
一种风机进风口密封装置,包括进风口、叶轮,进风口与叶轮相对布置,靠近叶轮一侧的进风口上设置凸出装置。
本发明采用上述技术方案,与现有技术相比具有如下优点:本发明在进风口与叶轮配合处加一密封凸出装置,有效防止回流现象,并提高了进风口与叶轮配合的圆度及同心度,工艺相对简单,节约成本,提高了风机的效率。
附图说明
图1是本发明的一种结构示意图。
具体实施方式
下面结合附图对本发明的技术方案进行详细说明:
如图1所示,一种风机进风口密封装置,包括进风口1、叶轮2,进风口1与叶轮2相对布置,靠近叶轮2一侧的进风口1上设置凸出装置3。
