Turbocharger Impeller Function Failure Causes and Hazards

A diesel engine relies on a turbocharger to increase the engine's air intake. The turbocharger is essentially an air compressor. It uses the exhaust gas discharged by the engine as power to drive the turbine in the turbine chamber, which then drives the coaxial impeller located in the intake passage. The impeller compresses the fresh air delivered by the air filter pipeline and sends it into the cylinder. When the engine speed increases, the exhaust gas discharge speed and turbine speed also increase simultaneously, the degree of air compression is increased, and the engine's air intake is correspondingly increased, which can increase the engine's output power.

Common faults of generator set turbochargers include bearing burnout, impeller fracture, reduced boost pressure, excessive boost pressure, and compressor surge. Although the probability of impeller fracture is low, it is particularly important to master and understand the relevant fault causes. The specific causes and hazards of the impeller body of Dingbo Electric generator sets are as follows:

Blade fracture or damage is mainly caused by foreign objects. Because the turbine blades are exposed to high-temperature combustion and rotate at high speed, even a small hard object can generate a large impact, causing the blades to bend or crack.

If the impeller of the Dingbo Electric diesel generator set turbocharger breaks, when the unit's turbocharger is running stably at a certain moment, the air delivered to the combustion chamber is insufficient, and the generator set will make a panting sound, which is what we professionally call unit "surge". This will cause changes in the airflow channel, resulting in mismatching between the diesel engine and the turbocharger, affecting the normal operation of the diesel generator set.
