York YK Chiller Motor’s Stator with loose fiber wedges. Rubbing on rotor caused by loose fiber wedges. Bearing fluting caused by improper motor shaft grounding. Both issues were found through use of vibration analysis, which is an essential tool in predicting wear in chiller compressors and motors. We recommend taking vibration samples on chillers at […]
Thermetrics technicians disassembling a York Chiller for an overhaul repair in Orlando. The high speed thrust was found out of allowable tolerances during inspection. Teardown to determine the underlying issues was recommended resulting in this repair. Chiller’s bearings were found out of tolerance, impeller nose seal damage, and minor damage to the high speed gear […]
