Abstract

本实用新型公开了一种具有安装定位准确、振动小、密封好的井筒式污水泵。它包括潜水电机、设于潜水电机输出轴端的叶轮,所述叶轮外周设有导叶,所述导叶由上盖板、下盖板及上盖板与下盖板之间的多只叶片组成,所述下盖板外周设有定位面。本实用新型适用于井筒式污水泵。

Description

井筒式污水泵
技术领域
本实用新型涉及一种污水处理设备,尤其涉及一种用于浇性污泥的提升及回流的污水泵。
背景技术
目前国内污水处理厂浇性污泥的回流主要使用潜水轴流泵或潜水混流泵,这些泵具有流量大、扬程低、效率高等特点,但是同时存在以下一些不足或缺陷:一是性能不稳定。主要表现为输送污泥时流量大幅度下降;二是功率大、电机易损坏。而井筒式污水泵具有潜水轴流泵及潜水排污泵的优点,主要水力部件叶轮具有大通道、高效、无堵塞、全扬程等特性,因而推广应用优势明显。但由于其安装型式为井筒式,类似于潜水轴流泵,不同程度存在安装定位不准;振动较大;工作时污水回流等问题。
实用新型内容
本实用新型要解决的技术问题是提供一种具有安装定位准确、振动小、密封好的井筒式污水泵。
为了解决上述技术问题,本实用新型是通过以下技术方案得以解决的:
本实用新型包括潜水电机、设于潜水电机输出轴端的叶轮,所述叶轮外周设有导叶,所述导叶由上盖板、下盖板及上盖板与下盖板之间的多只叶片组成,所述下盖板外周设有定位面。
作为优选,所述下盖板外周还设有密封沟槽。
本实用新型与现有技术相比,具有以下明显优点和积极效果:
1、安装定位准确。由于本实用新型中导叶在下盖板外周增设了定位面,安装时定位面与安装部位接触,即可实现自动定位,不仅使安装方便,而且提高了定位的准确性。
2、运行振动小、密封好。由于本实用新型中导叶在下盖板外周增设了密封沟槽,安装时在密封沟槽上设O形密封环,由于O形密封环与安装部位良好接触,不仅有效减少运行振动,而且起到良好的密封效果,有效防止污水回流。
附图说明
图1是本实用新型的结构示意图;
图2是图1中导叶的结构示意图;
图3是图2的A-A向剖示图;
图4是图3中I处放大图。
具体实施方式
下面结合附图,对本实用新型的技术方案作进一步详细说明。
如图1至图4所示:本实用新型包括潜水电机1,潜水电机1输出轴端设有叶轮2,叶轮2外周设有导叶3,导叶3由上盖板4、下盖板5及上盖板4与下盖板5之间的多只叶片6组成,叶片6呈螺旋状分布,导叶3下盖板5外周设有定位面7,定位面7轴向剖面为斜面,定位面7与安装部位的形状相适配,安装时可实现良好接触,从而达到自动定位的目的;在下盖板5外周还设有密封沟槽8,密封沟槽8轴向剖面形状呈L型,密封沟槽8端部及转角处设有圆弧,这样既能保证O型密封圈的方便安装,又能有效防止O型密封圈的脱落,同时有利于减小运行振动。
