Balancing
After repair, it is required to test the balance of the assembled turbocharger at operating speed
Balancing is done on a SCHENCK CAB950T-S machine – the absolute leader in this area
The maximum value of effective scanning is 250,000 rotations per minute
Balancing of a wide range of turbochargers
Possible to use for turbochargers designated for sport applications
Imbalance causes noise and vibrations – unpleasant and dangerous at high speeds
Output is a graphical diagram – illustration of progress and imbalance
Imbalance can affect:
Lifetime – bearings can be highly stressed by vibrations, subject to major wear and tear
Safety – vibrations can cause disconnections, risk to both humans and machines
Quality – affected by vibrations and trembling, high-speed machines do not work in a “clean” way
Competitiveness – quiet and silent running is always a sign of quality = competitiveness
One of the most important options of the complex offer of services related to turbochargers is testing
Consists in the physical revving of the turbocharger and subsequent identification of the following:
Vibration level Brüel & Kjaer sensor
Casing tightness verification – oil leakage in certain points of pressure
Control function verification
Radial and axial clearance measurement
The testing laboratory output identifies the turbocharger condition along with testing protocol completion
