Description

自吸旋涡泵
本实用新型涉及一种自吸旋涡泵。它属于不装底阀的微型、小型开式旋涡泵，主要用于家庭供水、楼房给水。
本实用新型主要由后盖板、开式叶轮、前盖板、密封装置、止回阀、罩形泵壳及电机组成。
现使用的自吸旋涡泵有的结构复杂、不易制造，有的效率较低。同类自吸旋涡泵中有韩国产的PW-261M型。
为解决现有技术的不足，本实用新型提供一种结构简单、容易制造、效率较高的自吸旋涡泵。
本实用新型采用下述方法实现：在电机轴上安装一个开式叶轮，其前端及顶面与带有吸入口的前盖板配合、后端与带有环形流道及流道排出口的后盖板配合；前盖板及后盖板装配于罩形泵壳之中，组合成的蓄水室与进水管相邻、增容腔与出水座相通；后盖板后部与电机连接，中心部位安装密封装置。
本实用新型结构简单，效率较高。
附图给出本实用新型的最佳实施例。
附图为实施例的结构图。
附图中在电机轴2上安装一个开式叶轮7，其前端及顶面与带有吸入口8的前盖板9相配合、后端与带有环形流道6及流道排出口5的后盖板3配合连接；前盖板9及后盖板3装配于罩形泵壳11之中，组合成的蓄水室17与进水管12相邻、增容腔16与出水座15及排气孔14相通；后盖板3后部有定位孔13与电机1配合连接，中心部位安装密封装置4。
当泵内加满水启动电机1后，旋转的开式叶轮7便具有自吸能力。此时吸水管中的空气便由进水管12、止回阀10进入蓄水室17与水形成液气混合物。该混合物从吸入口8经开式叶轮7进入环形流道6。开式叶轮7将其加速后由流道排出口5压向增容腔16，空气即从水中分离、经由排气孔14和出水座15排出。液体返回环形流道后重复排气过程，直至空气除净泵进入正常供水。
