Abstract

本实用新型涉及到管道泵的连接装置,由于管道泵输送介质时容易造成电机轴的腐蚀,从而造成电机的损坏,采用一种隔离装置,可以大大减少对电机轴的污染且互换性增强从而达到降低成本,提高效率的目的。

Description

管道泵
经检索有关文献,现有的管道泵均使用专用电机,也就是说电机轴加长,在电机轴顶端车有螺纹,叶轮套在电机轴上,这样电机的轴就与泵腔内的介质直接接触。如果输送腐蚀性的介质,电机的轴就需要作特别的处理。当机械密封失去功效时,介质就会顺着电机轴进入电机,造成电机的损坏,叶轮被腐蚀后,电机轴也会受腐蚀,这样整个电机就要报废,很不经济。
本实用新型的目的,就是针对上述缺陷,提供一种减少电机受腐蚀,降低其经济成本的装置。
为实现这个目的,在管道泵11与电机1之间使用支架相接,这样使用普通的电机就可以达到所需的要求。腐蚀性介质只与支架12接触,而与电机1无关,电机轴2与泵轴使用平键7和固定螺钉固定。在管道泵11与电机1间设一档水圈4,当泵内的机械密封遭损坏后,介质也不会流入电机,而当泵的叶轮10受腐蚀,不能正常运转时,可以换上新的管道泵,而无需更换电机,这样互换性就大大加强,从而降低了成本,提高了效益。
图1为管道泵结构示意图。
电机1的轴2与管道泵的泵轴8用平键7和固定螺钉3固定,电机1与管道泵用支架12相接,在泵轴8上设有挡水圈4和机械密封5并有轴承16固定,泵体11和支架2与电机1的连接均采用螺栓固定,使安装和维修均很方便。
