DESIGN OF AUTOMATED SYSTEM FOR ADJUSTING THE SPAN BETWEEN THE BUNDLES OF IDLERS/ ROTATORS FOR SUPPORTING HEAT EXCHANGER SHELLS

Idlers and Rotators are used for supporting and rotating the heat exchanger shell during its manufacturing process. The shell is rested on Bundles which needs to be adjusted according to the diameter of the heat exchanger shell. The distance between the bundles is adjusted by rotating a lead screw manually with spanner or striking it with hammer, thus an automated system is needed to be design to automate this process in order to ensure safety of this operation, reduce the cycle time and fatigue caused to workmen to perform this activity.
