Description

平衡鼓
技术领域
本实用新型涉及一种平衡鼓。 
背景技术
在煤矿、铁矿、化工、电站等领域广泛使用着多级离心泵。目前市场上卧式、立式多级泵,其大多数采用平衡盘、平衡鼓和盘鼓结构。其平衡原理是靠节流产生压差工作的。但如果为了提高压差而减小径向间隙,这样会给装配等带来很大的困难,而且还容易出现故障,导致设备不能正常运行。如果增大径向间隙,就降低了泵的效率,额外消耗了电机的功率。 
实用新型内容
本实用新型提供一种结构简单、节流效果更高、工作效率高、运行更加平稳的平衡鼓。 
本实用新型解决技术问题提供如下方案: 
一种平衡鼓,包括平衡鼓本体,所述平衡鼓本体内侧壁上设有键槽,所述平衡鼓本体的前端具有法兰,所述法兰上设有多个螺栓安装孔,所述平衡鼓本体的前后两个端口都设有台阶槽,所述台阶槽内镶嵌有密封圈。 
所述平衡鼓本体的侧壁上设有沿半径方向的销孔。 
本实用新型解决了现有的技术中存在平衡鼓在安装后,由于大压力已经震动的环境下,出现松动以及漏水等一些情况。 
附图说明
图1为本实用新型的结构示意图。 
具体实施方式
参见附图,一种平衡鼓,包括平衡鼓本体1,所述平衡鼓本体1内侧壁上设有键槽2,所述平衡鼓本体1的前端具有法兰3,所述法兰3上设有多个螺栓安装孔4,所述平衡鼓本体1的前后两个端口都设有台阶槽5、6,所述台阶槽5、6内镶嵌有密封圈7,所述平衡鼓本体1的侧壁上设有沿半径方向的销孔8。 

Claims (2)
