A turbocharger is actually an air compressor that increases the intake volume by compressing air. The impeller pressure delivers air from the air filter pipeline, which is pressurized and enters the cylinder. When the speed increases, the exhaust emission speed and impeller speed also increase synchronously. The impeller compresses more air into the cylinder, and the air pressure and density increase, which can burn more fuel. Correspondingly, the fuel amount is increased, the speed is adjusted, and the locomotive output power is increased.
The turbocharger rotor shaft is used in high-speed operating environments, with a speed of 10000 to 200000 revolutions per minute. Under such high-speed rotation, it is necessary to achieve dynamic balance. Efficient dynamic balance detection can be achieved through intelligent turbocharger balancing.
The rotor shaft and body refer to forgings with sufficient mechanical strength to withstand the torque of the prime mover and sudden short circuits at the generator outlet, and have good magnetic permeability. They are the carriers of the main magnetic poles of the generator.
At present, the working speed of the turbocharger rotor assembly can reach 60000 r/min to 240000 r/min. The turbocharger rotor, as the core component of the turbocharger, can cause significant vibration and noise due to rotor imbalance during high-speed rotation, directly leading to wear of floating bearings, thrust bearings, and even sealing components, thereby reducing the service life of the turbocharger and laying hidden dangers for safe driving. Therefore, it is necessary to perform dynamic balance detection and calibration on the turbocharger rotor.
