Description

便拆型立式双吸离心泵
本实用新型步及一种泵，具体地说是关于一种立式离心泵。
现有的立式离心泵均采用中开式结构，包括电机、泵体、泵盖、底脚、叶轮、叶轮轴和轴承，泵体与底脚铸为一体，轴承装在叶轮上方的泵盖和电机内，这和结构的立式离心泵加工工艺复杂，且都是单吸式结构，效率较低，叶轮运转不稳定，维修时需先拆下电机和泵盖，非常费时、烦锁。
本实用新型的目的是设计一和效率高、叶轮转动稳定、维修方便的便拆型立式双吸离心泵。
实现本实用型目的的技术方案包括：电机、电机支架、泵体、底脚、叶轮、泵轴、轴承、密封件和安装件，其泵体与叶轮流道为双吸结构，泵轴的两端都有轴承定位，泵轴与电机轴由联轴器连接，联轴器外的电机支架开有窗口。
本实用新型与现有技术相比的有益效果在于采用双吸式结构，泵轴采用两端轴承定位，泵轴与电机轴由联轴器连接，提高了泵的工作效率和运行稳定性，维修方便、省时。
图1是本实用新型的总装图。
图2是本实用新型联轴器结构图。
图3是本实用新型图2E-E方向剖视图。
现结合附图详细描述本实用新型的实施例。
如图1所示的便拆型立式双吸离心泵，包括电机3、电机支架2、泵体1、底脚8、叶轮7、泵轴6、联轴器4、轴承5、9以及密封件和安装件，泵体1铸成一体型结构，泵体1与底脚8以及电机支架2之间分别由螺栓连接，相互之间用硬密封。泵体1和叶轮7制成双吸式流道，泵轴6穿过叶轮7伸到底脚8内，采用两端轴承定位，轴承5、9采用复合轴承。电机支架(2)开有窗口，可从窗口更换泵体内各部件。联轴器4由两半对称壳体10、11和卡环、键组成，壳体10和壳体11内圆臂相对位置分别制有两个卡环槽和一个键槽，电机轴和泵轴6上制有卡环槽和键槽，位置分别与联轴器4上的卡环槽和键槽相对应，壳体10和壳体11由紧固件紧固。
