The VSR  GRAND SBR-20 is a Vibration Sorting Rig that was designed for entry level turbocharger repair workshop including medium re-manufacturers and OEM producers.

The purpose of the machine is to measure the vibration specifically for passenger cars and lightweight cartridges by boosting the rotor rotation up. It also allows checking turbocharger for oil leakage.

SBR-20 made it possible to achieve maximum operating rotation frequencies in some cases reaching 250 000 rpm. However, reaching 50 000 rpm, a turbocharger begins to behave like a “flexible type” rotor, sausage alike. This leads to obtaining an unnecessary vibration level which interferes turbocharger operation.

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.

Design features of the machine

  • Turbocharger cartridge is set to the standard mounting surface with the oil supply to the slide bearings at operating pressure and temperature.

  • Design allows to connect cartridges of all types and all manufacturers to the hydraulic system of the machine using equipment supplied with the machine. The adapter for turbines with bottom oil supply are included in a standard set.

  • Free-standing oil tank 12 liters, 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 to move the turbine cartridge from the machine.

  •  Heating of oil up to 65 °C that allows to use inexpensive semi-synthetic brands.

  • Adapters to accelerate the turbine to the operating speed is specifically designed for ease of manufacture in a repair shop, and maximally unified.

  • All electrical equipment of industrial performance, is located in a cabinet.

Special balancing system PAK-SBR

  • Displaying of imbalance measurement in real time (during rotation) – prevents possible collapse of the turbine during test.
  • Determination of vibration of the turbocharger center housing – up to the size of 10G that surpasses the European analogues twice.
  • Graphical display of vibration acceleration and phase depending on the rotational speed of the turbine during acceleration.
  • Simultaneous display of the results of two measurements on the same graph for analysis.
  • Display of phase in the pie chart to simplify the determination of the place of unbalance.
  • Access to self-edit turbines base.
    • Creation and printing of reports on the rotor balancing.
