PROCEDIMENTO DI EQUILIBRATURA E MACCHINA BILANCIATRICE DI GRUPPI TURBOCOMPRESSORI IN PARTICOLARE PER MOTORI SOVRALIMENTATI

摘要

The process consists in associating a substantially complete turbosupercharger unit with an unbalance-detecting device, supplying the turbosuperchager unit with lubricating oil at the same temperature and pressure as the operating ones, setting the rotor of the turbosupercharger unit in rotation by a compressed air flow, and carrying out detection of unbalances under these conditions. The machine comprises an unbalance-detecting device (2) adapted to engage a turbosupercharger unit (7), a feeding device (20) for feeding oil at the operating temperature and pressure, and a delivery device for delivering compressed air (23) to the rotor (11) of said turbosupercharger unit (7). $$
