In this project, due to the compressor bearing failure and damage to the second crankpin journal, and the lack of facilities and heavy cost of removing the crankshaft from the compressor location, grinding was performed on-site. Due to the loss of the crankshaft fillet radius and the lack of a guide for grinding, the installation of the portable grinding machine had encountered problems. Khuzestan Water and Power Company used the Laser Tracker services of Abad Deghat Markazi Company to adjust the position of the grinding machine and correct the fillet radius.
Initially, by measuring the crankshaft and obtaining the location of the damaged part, the portable grinding machine was adjusted in its original place and position relative to the crankshaft axis, and the grinding machine proceeded to create a new fillet radius.
After creating a guide for the final grinding, the final grinding operation was carried out with online geometric and dimensional control by the Laser Tracker device.
Finally, the project was completed with the repair and successful testing of the compressor.
