Read how SAM4 caught a loose blast wheel belt guard before it caused damage to this steel manufacturer’s shot blasting machine.
Failure mode
A loose belt guard in one of the blast wheels disturbed the operation of that blast wheel and its neighbor.
How SAM4 helped
SAM4 flagged a sudden spike at the rotational frequency for two of four blast wheels in this shot blasting machine. In the days that followed, the intensity continued to rise for both wheels. The machine’s other two blast wheels showed no such trend. The customer inspected both wheels five weeks later, during a planned maintenance stop. The belt guard on one of the blast wheels had come loose; there was no visible problem on the other. The customer tightened the belt and replaced the damaged belt guard on the faulty wheel, after which both machines returned to normal operation.
Outcome
“SAM4 kept us from overlooking parts that needed attention but weren’t originally scheduled for inspection during this stop.”
