Why do automobile turbocharger wheel need to do dynamic balance testing? Turbocharger is actually a kind of air compressor, by compressing air to increase the air intake. It is the use of the engine exhaust gas inertial impulse to push the turbine indoor turbine, turbine and drive the coaxial impeller, impeller pressure to send the air from the air filter pipe, so that the pressurization into the cylinder. When the engine speed increases, the exhaust gas discharge speed and turbine speed also increases simultaneously, the impeller will compress more air into the cylinder, the air pressure and density increases can burn more fuel, correspondingly increase the amount of fuel and adjust the engine speed, you can increase the engine output power.

Now more applications are engine exhaust gas turbocharger, turbocharger rotor shaft used in a high-speed operating environment, up to 10,000 to more than 200,000 revolutions per minute, in this high-speed rotation will have to do dynamic balancing.

Turbocharger impeller rotor shaft and the body has sufficient mechanical strength to withstand the torque from the prime mover and the huge electromagnetic torque of the sudden short circuit at the generator outlet, and has good magnetic conductivity forgings for the main magnetic pole of the generator carrier.

With the continuous development of automotive turbocharging technology, the turbocharger rotor assembly can now work at speeds of 60,000r/min to 240,000r/min. supercharger rotor as the core component of the supercharger, in the high-speed rotation, the rotor imbalance will cause greater vibration and noise, which directly leads to wear of the floating bearings, thrust bearings and even sealing parts, which in turn reduces the The life of the supercharger, but also for the safety of driving laid a hidden danger. Therefore, turbocharger rotor to do dynamic balance testing and correction, is very necessary.

REFONE has strict control standards for the balancing of turbochargers and their components, and not only sells turbocharger series, but also supplies turbocharger balancing machines. Feel free to contact us(market9@cnrefone.com) if you have a need in this area
