VSR GRAND turbocharger balancer SBR-20

The machine is designed for the high-speed balancing of turbochargers at speeds reaching maximum operational values to eliminate the dynamic unbalance of the turbine rotor. Used for balancing large turbochargers of special equipment, railroad and marine turbines, industrial turbochargers for diesel generators. The SBR-20 simulates the same conditions during testing and balancing as during the operation of a turbocharger on a car; this allows you to guarantee the quality of the repair.

VSR tasks

The main task of the SBR-20 is to determine the intensity and direction of the deflection as well as in what exact period of time and at what frequencies it appeared. This information is being analyzed by measuring system and it is possible to balance the shaft of the turbine.

The second task is to prevent damaging the parts of the turbocharger during the balancing process. The hydraulic system is installed in machine in accordance with this task.
It helps to create an “oil wedge” in the gaps between the parts of the turbo compressor which prevents the parts from contacting each other and their reliable protection is ensured.

The SBR-20 emits the same conditions during testing and balancing as when the turbine is operating within a car and this allows us to guarantee the quality of repair of this unit

A well-balanced turbocharger has a long service life which reduces the return rate of turbochargers and helps to build up your reputation.

The universal 22 type adapter set and accessories cover mostly all turbocharger core types including reverse rotation ones.

PRODUCT HIGHLIGHTS

Design features of the machine

VSR GRAND turbocharger balancer features:

Not only the turbocharger cartridge is set to the standard mounting surface, but also with the oil supply to the slide bearings at operating pressure and temperature.
The design allows to connect not only cartridges of all types but also all manufacturers to the hydraulic system of the machine using equipment supplied with the machine. Moreover, the adapter for turbines with bottom oil supply are included in a standard set.
Freestanding oil tank capacity is 12 liters, so no refilling of oil is required.
3-stage system of oil filtration allows to eliminate an unbalance directly on the machine by portable grinders. This procedure does not require moving the turbine cartridge from the machine.
You can heat the oil up to 65 °C, i.e. that allows to use inexpensive semisynthetic brands.
In addition, adapters to accelerate the turbine to the operating speed are specifically designed for ease of manufacture in a repair shop, and also maximally unified.
Finally, all electrical equipment, of industrial performance, is located in a cabinet of the VSR GRAND turbocharger balancer.

Special balancing system PAK-SBR

In order to prevent possible collapse of the turbine during test, PAK-SBR displays imbalance measurement in real time (during rotation).
The balancing system determines the vibration of the turbocharger central housing up to 10G, that altogether surpasses most of the European analogues twice.
Graphical display shows vibration, acceleration and also phase, which depends on the rotational speed of the turbine during acceleration.
Simultaneous display of the results of two measurements on the same graph allows you to analyze problems with installed turbocharger quicker.
Display of phases in the view of pie chart simplifies the determination of the unbalance place.
Furthermore, you have access to edit turbines base.
Finally, the balancing system could create and print the report of the rotor balancing.
