Decatur Industrial Electric is regularly scheduled at a customer site to inspect and maintain their equipment to ensure optimal performance. Our routine inspections help reduce unexpected downtime and extend equipment life.This particular inspection included an air flow measurement of a large DC motor forced air cooling system. Our reliability specialists determined the air flow was not within normal value and further investigation was needed to determine the cause. Upon disassembly, we could readily see an excessive buildup of oily dirt in the impeller and the housing.
A D.I.E. technician cleaned both the impeller and the housing on-site and restored the cooling fan to its optimal performance levels. When cleaning these components it is very critical that all the contamination be removed from the impeller. The blower was returned to service in just a short period of time.
Through routine maintenance, this issue was discovered before it became a larger more costly problem or caused downtime.
