According to the Department of Commerce, there about 12.4 million electric motors in use in industrial operations across the United States that operate at 1hp and above. Approximately 25% of these motors will fail in the coming year. Machine alignment can help those motors run more efficiently, which saves costs in energy consumption and reduces the punitive costs that can come with excessive harmful emissions.
What is Machine Misalignment?
Misalignment is the leading cause for machine failure. It occurs when the center lines of two shafts do not line up as they should. Misalignment can destroy seals, bearings, couplings, stators, rotors, shafts, and more. It destroys components by adding stress forces that are transferred throughout the entire machine and reduces its productive life. Misalignment causes more rotating equipment failure then the next two issues combined: unbalance and poor bearing install.
Signs of Machine Misalignment
Machines that are misaligned are not always easily diagnosed. However, they may show mild to severe signs of one or more of the below:
You shouldn’t solely rely on visual inspections to check the alignment of your machines. The dial indicators can be more accurate, but do not provide real-time values to help measure the correct alignment simultaneously. In fact, dial indicators should be removed and reinstalled after each alignment is completed. It is essential to have the proper technology and tools in order to properly diagnose a misalignment.
Types of Misalignment
The two types of misalignment include:
It is possible for a machine to simultaneously experience both parallel and angular misalignment at the same time. Both need to be corrected before it can be put back in use.
How to Diagnose Misalignment
There are several methods for detecting misalignment, that include:
