Laser shaft alignment is a process of aligning the rotational centerlines of two or more shafts in rotating machinery, such as pumps, motors, compressors, and turbines. The goal of laser shaft alignment is to ensure that the shafts are perfectly aligned to minimize vibration, reduce wear and tear, and improve the overall efficiency and reliability of the machinery. The laser shaft alignment process involves the use of a laser alignment tool, which emits a laser beam that is directed at a detector mounted on the opposite shaft. The laser tool measures the relative positions of the shafts and provides real-time feedback to the operator, who can then adjust the alignment as necessary.
