The invention relates to an anti-eccentricity device for a pumping device. The anti-eccentricity device reduces free movement of a pumping rod and reduces eccentric movement of an internal part caused by external force at the same time. Disclosed is an anti-eccentricity device for a pumping device, comprising: a rod bracket coupled to a pumping rod; a housing having a clutch device disposed therein and coupled to a position facing the lever bracket by the clutch device; and an elastic member that provides an elastic restoring force in a direction that counteracts an eccentric movement in which the clutch device bends about the rotation axis, and that is elastically supported on the lever bracket.
本发明涉及一种用于泵送装置的防偏心装置,该防偏心装置在减少泵送杆的自由运动的同时减少由于外力引起的内部部件的偏心运动。公开一种用于泵送装置的防偏心装置,其包括:杆支架,联接到泵送杆;壳体,其中设置有离合器装置并通过离合器装置联接到朝向杆支架的位置;以及弹性构件,在抵消离合器装置围绕旋转轴线弯曲的偏心运动的方向上提供弹性恢复力,并弹性地支撑在杆支架上。
