ABRO BALANCING MACHINES
HIGH SPEED BALANCERS
The ABRO HR Series has worked with M/S MAN Turbo to balance rotors at speeds of up to 18,000 RPM and achieve low vibration levels that were never thought to be possible. Those days are gone when in order to meet to meet specifications like API-612 on high speed balancing machine, one must employ API deviations. On the HR series you can meet all existing balancing and vibrations standards for turbines, compressors and armatures.
The ABRO high speed balancing machines combine high rigidity with high sensitivity. Site conditions can be created by selecting the desired stiffness and if necessary by using the actual bearings of the rotor. Therefore, accurate low speed and high speed balancing is possible for rotors with widely varying weights and speeds.
Here are some examples of high speed balancers manufactured by ABRO.
Balancing Turbomolecular Pumps at 90,000RPM
An ABRO soft bearing balancing machine has been supplied for the balancing of turbomolecular pumps in a vacuum level of 0.01m bar.
Burst testing of jobs in a spin pit
ABRO has manufactured an integral high-speed balancing machine and spin pit. This facility would be used to test jobs for their mechanical strength. Parts are run to high-speed till they disintegrate (burst). The machine is provided with 5 annular rings for containment of bursted particles.
Facility for balancing completely assembled motors
ABRO has developed a facility to balance completely assembled motors on the HR series high speed balancing machines which have high rigidity and sensitivity. Motors weighing 10 Ton can be balanced on the HR-5K machine at a speed of 3000 RPM without encountering any pedestal resonance.
