After our technical team's disassembly and analysis of the damaged turbocharger, as well as on-site inspection of the turbocharger's usage, we found a common problem, which is that the equipment with the problem of turbocharger impeller explosion works for a relatively long time every day, averaging over 20 hours per day. The turbocharger works under high load for a long time, and the high temperature of the turbocharger causes damage to the impeller due to fatigue
After our company's technical dismantling and inspection of the damaged turbocharger, we found that there is a common point that the turbocharger is all due to bearing wear caused by high-temperature burning of the shaft, resulting in the failure of the turbocharger. After communicating with the customer, we have reported that the engine temperature is higher than normal.
