How do you use laser alignment tools to improve accuracy and efficiency?

1 What are laser alignment tools?

Laser alignment tools are devices that use a laser beam and a detector to measure the angular and offset misalignment between two or more shafts or couplings. The laser beam is mounted on one shaft and the detector on the other, and the device displays the results on a screen or a software interface. Some laser alignment tools can also measure the soft foot, thermal growth, and dynamic movement of the equipment.

2 Why use laser alignment tools?

Laser alignment tools offer several advantages over traditional methods, such as dial indicators, straight edges, or feeler gauges. Laser alignment tools are more accurate, faster, easier, and safer to use. They can also provide graphical and numerical feedback, data storage, and report generation. Laser alignment tools can help you achieve the best possible alignment within the tolerance specified by the equipment manufacturer or industry standards.

3 How to prepare for laser alignment?

Before using laser alignment tools, you should lock out and tag out the equipment to prevent accidental start-up or injury. Additionally, remove any guards, covers, or couplings that may obstruct the laser beam or the detector. Clean the shafts and the mounting surfaces of the laser alignment tools and check the condition and alignment of the bearings, seals, and bases of the equipment. Furthermore, correct any soft foot or base bolt issues that may affect the alignment and pre-align the shafts manually to reduce the gross misalignment and the number of corrections.

4 How to perform laser alignment?

In order to perform laser alignment, you must adhere to the instructions of the laser alignment tool manufacturer or supplier. Generally, this process involves attaching the laser beam and detector to the shafts or couplings using brackets, chains, or magnets. You must then turn on the laser alignment tool and enter parameters such as shaft diameter, coupling type, and alignment tolerance. Subsequently, you should rotate the shafts together by hand or with a jacking device, taking measurements at 0, 90, 180, and 270 degrees. After viewing the results on the screen or software interface and making any necessary adjustments with shims, bolts, or wedges, repeat the rotation and measurement until the alignment is within tolerance. Finally, confirm the alignment by running the equipment and checking vibration, temperature, and current.

5 How to maintain laser alignment tools?

To keep laser alignment tools in good condition, it is essential to store them in a dry, clean, and secure place when not in use. They should also be protected from dust, moisture, shock, and extreme temperatures. Cleaning them regularly with a soft cloth and a mild solvent is important for maintenance. Additionally, calibrating them periodically according to the manufacturer's recommendations or industry standards is necessary. Before and after each use, you should check them for any damage or defects, and replace any worn or broken parts as soon as possible. By following these best practices and tips, you can use laser alignment tools effectively and safely while improving accuracy and efficiency in rotating equipment.
