DEMONSTRATION OF TURBOCHARGERS BALANCING PROTOTYPE MACHINE FUNCTIONALITY IN RELEVANT OPERATING CONDITIONS

Sigismund BECZE, Petru BERCE, Nicolae PANC

Abstract


A turbocharger must be measured on a VSR (vibration sorting rig) and balanced in order to obtain a durable product who will withstand the service life specified by manufacturer (generally 1- or 2-years warranty depends by manufacturer or type of turbocharger). Unbalance of turbocharger rotor creates always vibrations which could be very destructive for the bearing. The purpose of experiment is to prove balancing is possible without any prediction algorithm still with good results. For the demonstration of manual balancing a prototype machine was built and 10 turbochargers were used.
