Turbocharger core balancing machine DBST-20

Low-speed turbocharger core balancing machine meets the needs of turbocharger repair workshops.

Machine is used for balancing common truck and passenger car turbos. It is multi-functional and universal, so it is suitable for many large turbochargers of special vehicles, railroad and marine turbines, and even for industrial turbochargers of gas and diesel power plants.

The DBST-20 is used for balancing common truck and car turbochargers. It is multifunctional and universal, so it is suitable for many large turbochargers of special vehicles, railway and marine turbines, and even industrial turbochargers of gas and diesel power plants.

This stand allows for the final balancing of cartridges due to the specific design features of large turbines.

The stand is used for balancing turbocharger cartridges at low speeds, as well as for checking turbocharger cartridge oil leaks.

This is a larger version of the DBST-10 model that our company has developed specifically for large turbochargers weighing up to 30 kg.

HIGHLIGHTS

High accuracy of determining the unbalance of the rotor (0.4 g ∙ mm / kg).

Reinforced torsional vibration suspension - high accuracy of vibration transmission, quality balancing results.

Mounting the cartridges on their standard surfaces (as on the engine) allows the installation of almost all turbochargers.

Wide range of accessories and adapters for installing any kind of turbos.
Includes adapters for installing turbochargers with lower oil inlet.

Oil system with oil heating allows to recreate similar conditions to the real one during balancing.

3-stage system of oil filtration allows to eliminate an unbalance directly on the machine by portable grinders.

The measuring system displays the balancing process in real time and monitors the rotor unbalance behaviour on the screen to achieve the best possible result.

Rotor adjustment and machine calibration are performed by the operator, ensuring maximum machine sensitivity at all times.

Safe turbo shaft speed allows risk-free quality running-in of assembled cartridges, which significantly increases cartridge reliability after repair.
