Abstract

本实用新型涉及对潜水轴流泵、潜水混流泵的吸入室结构改进。包括进水喇叭，其特征在于：进水喇叭上有四根环形加强筋，四根环形加强筋相互平行于进水喇叭的进口端面，导水锥与进水喇叭铸造连接。本实用新型的优点是铸造更方便，减少铸造模具数量，减少加工量及零件数量，节省时间，提高了工作效率。同时也加强了吸入导流功能，同时也提高了泵的效率，增强了结构强度。

Description

具有强导流功能的进水喇叭
技术领域
本实用新型涉及对潜水轴流泵、潜水混流泵的吸入室结构改进。
背景技术
如附图(1)所示的传统潜水轴(混)流泵吸入室为一个进水喇叭11，进水喇叭内部中空结构，强度不好，当水池流态不好时会产生旋涡，导水锥12用螺钉固定在叶轮上，增加了电机的负载，并且导水锥并不能完全消除旋涡，因此有必要设计一种新结构对此加以改进，以解决存在的旋涡问题。
发明内容：
本实用新型的目的是解决现有技术中传统潜水轴(混)流泵吸入室为一个中空结构的进水喇叭所存在的上述问题，提供一中具有强导流功能的进水喇叭。本实用新型设计具有强导流功能的进水喇叭，包括进水喇叭，其特征在于：进水喇叭上有四根环形加强筋，四根环形加强筋相互平行于进水喇叭的进口端面，导水锥与进水喇叭铸造连接。本实用新型的优点是铸造更方便，减少铸造模具数量，减少加工量及零件数量，节省时间，提高了工作效率。同时也加强了吸入导流功能，同时也提高了泵的效率，增强了结构强度。
附图说明：
图1为现有技术的结构示意图，
图2为本实用新型的结构示意图，
下面结合附图和施工实例对本实用新型作详细使用说明。
具体实施方式：
图中包括进水喇叭1，其特征在于：进水喇叭1上有四根环形加强筋2，四根环形加强筋2相互平行于进水喇叭的进口端面，导水锥3与进水喇叭铸造连接。
把导水锥与进水喇叭铸造时整体铸造好，中间铸造有有四个加强筋。这样的导水锥不用再打孔与叶轮联接，结构减少了联接螺钉及装配定位止，减少了加工量，安装、很方便，快捷，特别是导水锥不装在轴上，减少了电机的负载，节省了功率，提高了机组效率；同时进水喇叭上整体强度更好，而且加强筋且有消除水流吸入时产品的旋涡，与导流锥一起更加加强了导流功能，使吸入水流分布更均匀，提高了泵的效率。
