Turbo Dynamics are equipped with the latest balancing technology to balance every turbocharger using VSR High Speed Core Balancing and four-plane Dynamic Balancing machines. Four-plane Dynamic Balancing technology is used to balance turbochargers using computerised state of the art machines with rotor capacities of up to 20kg and 400mm diameter.
Turbochargers are assembled from component parts which are separately balanced using conventional low-speed, hard bearing balancing machines, and both the turbine wheel and compressor wheel are normally balanced in two planes. At the turbine end, the balance is not effected by assembly into the cartridge, but at the compressor end, small errors in the wheel, the shaft, the thrust collar and the nose nut can cause an accumulation of balance error. At high speed, this can result in a noisy turbocharger, and can cause premature bearing failure.
This imbalance can be corrected by running the assembled cartridge at high speed on a flexible suspension, measuring the vibration response, and either changing the assembly position or removing metal from the nose to achieve an acceptable balance. This operation usually requires the unit to be run at speeds close to the normal service operating speed, typically 100,000 to 200,000 rev/min, depending on wheel size.
