Description

防堵塞式二级自吸泵
技术领域
本发明涉及一种泵，具体是一种防堵塞式二级自吸泵。
背景技术
自吸泵的工作原理是：水泵启动前先在泵壳内灌满水（或泵壳内自身存有水）。启动后叶轮高速旋转使叶轮槽道中的水流向涡壳，这时入口形成真空，使进水逆止门打开，吸入管内的空气进入泵内，并经叶轮槽道到达外缘。
传统的自吸泵容易造成堵塞，泵的吸力小，影响泵的工作效率。
发明内容
本发明目的是提供了一种结构简单，且能够有效防止堵塞，泵体的吸力更大的防堵塞式二级自吸泵。
本发明解决技术问题提供如下方案：
一种防堵塞式二级自吸泵，包括支撑座，其特征在于：所述支撑座的上端安装有泵壳，所述泵壳的下端设有进水口，所述进水口连接进水管道，所述进水管道一端向下延伸穿过支撑座的侧壁，所述进水管道的口部安装有防爆电磁阀，所述进水管的侧壁上设有放液孔，所述泵壳内竖直安装有传动轴，所述泵壳内分为上、下两泵腔，且上、下两泵腔之间连通，所述传动轴的下端固定安装有一级叶轮，所述一级叶轮位于下泵腔内，所述上泵腔内的传动轴上固定安装有二级叶轮，所述上泵腔的侧壁上设有出水管，所述出水管处固定安装有单向阀。
所述传动轴的上端通过轴承支架传动连接电机。
本发明在支撑座的上端安装有泵壳，在泵壳的下端设有进水口，在进水口处连接进水管道，在进水管道的一端向下延伸穿过支撑座侧壁，在进水管道的口部安装有防爆电磁阀，便于自控，在进水管道的侧壁上设有放液孔，发生堵塞时，便于检修，且在泵壳内设有上、下两腔室，且在上、下两腔室内分别设有叶轮，提高了泵体的吸力，提高了泵的工作效率。
附图说明
图1为本发明的结构示意图。
具体实施方式
参见附图，一种防堵塞式二级自吸泵，包括支撑座1，所述支撑座1的上端安装有泵壳2，所述泵壳2的下端设有进水口3，所述进水口3连接进水管道4，所述进水管道4一端向下延伸穿过支撑座1的侧壁，所述进水管道4的口部安装有防爆电磁阀5，所述进水管4的侧壁上设有放液孔6，所述泵壳2内竖直安装有传动轴7，所述泵壳2内分为上、下两泵腔8、9，且上、下两泵腔8、9之间连通，所述传动轴7的下端固定安装有一级叶轮10，所述一级叶轮10位于下泵腔9内，所述上泵腔8内的传动轴上固定安装有二级叶轮12，所述上泵腔8的侧壁上设有出水管13，所述出水管13处固定安装有单向阀14。
所述传动轴7的上端通过轴承支架15传动连接电机11。
