Method for adjusting perpendicularity of sleeve of AP1000 refueling machine

The invention discloses a method for adjusting the perpendicularity of a sleeve of an AP1000 refueling machine, which is characterized by comprising the following steps of: 1, adjusting the perpendicularity of an outer sleeve; 2, adjusting the levelness of an inner sleeve balance arm; 3, adjusting the concentricity of the inner sleeve and the outer sleeve; 4, adjusting the gap between the inner sleeve and the guide wheel and ensuring that the guide wheel assembly is on the same plumb line; and 5, carrying out acceptance check. By means of the method, the perpendicularity of the outer sleeve can be ensured, it is ensured that the guide wheel is installed on a plumb line, it is ensured that the gap between the guide wheel and the inner sleeve meets the drawing requirement, and the operation perpendicularity and friction force of the inner sleeve can also meet the requirements. 本发明公开了一种AP1000装换料机套筒垂直度调整方法，其特征在于，包括以下步骤，步骤一：调整外套筒垂直度；步骤二：调整内套筒平衡臂水平度；步骤三：调整内外套筒同心度，步骤四：调整内套筒与导向轮之间的间隙并确保导向轮组件在一条铅垂线上；步骤五：验收。本发明的方法能确保外套
