Description

定子可摆动的单螺杆泵
技术领域
本实用新型涉及螺杆泵,具体涉及一种定子可摆动的单螺杆泵。
背景技术
螺杆泵是容积式转子泵,它是依靠由转子和定子形成的密封腔的容积变化来吸入和排出液体的。传统单螺杆泵的驱动电机通过绕杆与转子连接,并在转子外固定套设定子,且定子为不可摆动,工作时,转子会做偏心的圆周运动,为了避免因扭转角度过急而使绕杆疲劳过快断裂,绕杆需要设计得很长,这就导致螺杆泵的整体体积大,占地面积大,不能广泛应用于各种场合,有一定局限性。另外,上述结构的螺杆泵还存在噪声大、震动幅度大、输送效率较低等缺点。
发明内容
鉴于背景技术的不足,本实用新型所要解决的技术问题是提供一种定子可以摆动,大幅缩短绕杆的长度,减小螺杆泵整体体积,并有效实现减噪、减震和提速的定子可摆动的单螺杆泵。
为此,本实用新型是采用如下方案来实现的:
一种定子可摆动的单螺杆泵,包括驱动电机,所述驱动电机通过绕杆与转子连接,所述转子外套设有定子,所述绕杆、转子和定子均设置在三通内,其特征在于:所述定子一端为球形并可摆动地设置在三通的进料口端,所述进料口端设有与定子的球形端匹配的球形内壁。
所述定子采用弹性橡胶材料。
采用上述技术方案,定子的球形端与进料口端的球形内壁配合,可以实现万向摆动,在螺杆泵工作时,转子转动的同时,定子也会伺服摆动,既减小了绕杆上受到的压力,有效缩短绕杆的长度,又能降低工作时的噪音和震动。而且定子的球形端与进料口的球形内壁配合后,防止泵在输送过程中液体的压力过高时,保护橡胶软体被拉伤或拉断。另外,相比传统的单螺杆泵,可以设定更高的转速,使螺杆泵的流量增大,提高输送效率。
附图说明
本实用新型有如下附图:
图1为本实用新型的结构图。
具体实施方式
如图所示,本实用新型公开的一种定子可摆动的单螺杆泵,包括驱动电机1,驱动电机1通过绕杆2与转子4连接,转子4外套设有弹性橡胶材料的定子5,绕杆2、转子4和定子5均设置在三通3内,定子一端为球形6并可摆动地设置在三通3的进料口端,进料口端设有与定子5的球形端6匹配的球形内壁7。这种定子的球形端与进料口的球形内壁配合后,防止泵在输送过程中液体的压力过高时,保护橡胶软体被拉伤或拉断。
