Why Does Shaft Alignment Matter?
Alignment places connected shafts in the correct position for smooth operation.
Offset misalignment means the shaft centerlines are parallel but do not meet. Angular misalignment means they meet at an angle. Both can exist together. Soft foot happens when a machine foot does not sit flat on the base.
Alignment tools may use straightedges, dial indicators, or lasers. Skilled workers measure and adjust the machine under the approved procedure. Pipe strain must also be corrected. Pulling a pump into place with flange bolts can distort the casing.
After alignment, tighten bolts in the proper order and recheck. Run the equipment and verify vibration, temperature, current, pressure, and leakage. A precise tool does not help if the base, pipe, or fasteners move afterward.
Alignment should be checked under the conditions required by the procedure. Some machines change position as they warm. Large piping can also pull the pump after bolts are tightened. Final measurements and a documented test run show whether the complete installation stayed in place.
