Turbo and Core Assy Balancing Machine, with Dynamic Fluxing and DUO FLOW Oil Leak Tester

DUO FLOW combines two of the most important stages in turbocharger remanufacturing into a single platform: high-speed core assembly balancing and performance validation through dynamic flow testing.

The system not only corrects dynamic imbalances in the rotating assembly but also verifies the turbocharger's actual behavior during operation by simulating conditions extremely close to those encountered on the vehicle.

Balancing and Validation in a Single Process

After the high-speed balancing phase, the turbocharger can be directly subjected to dynamic flow testing without being transferred to other workstations.

This integration makes it possible to:

• reduce processing times
• eliminate additional setup operations
• increase productivity
• improve result repeatability

High-Speed Performance

DUO FLOW can operate at speeds of up to 250,000 RPM, allowing verification of the core assembly's dynamic behavior under conditions very close to real operating environments.

The analysis is performed using highly sensitive sensors that detect:

• vibrations
• dynamic imbalance
• rotational speed (RPM)

The acquired data makes it possible to correct any anomalies that could affect the turbocharger's reliability, noise levels, and service life.

Parameters Analyzed

Thanks to the integration of balancing and dynamic flow testing, the system can simultaneously monitor several operating parameters.

Turbine Side

• Inlet airflow rate
• Open geometry position
• Intermediate position
• Closed geometry position

Compressor Side

• Outlet airflow rate
• Rotating assembly efficiency

Dynamic Parameters

• Rotational speed (RPM)
• Vibration values
• Automatic comparison with reference database values

All of this information provides a complete overview of the turbocharger's behavior.

Operational Advantages

The combination of balancing and dynamic flow testing provides a more comprehensive verification process than traditional systems.

More Precise Control

The simultaneous acquisition of mechanical and fluid-dynamic data makes it possible to:

• objectively verify performance
• compare results with target values
• identify anomalies with greater accuracy
• validate correct turbocharger operation

Ideal for Remanufactured Turbochargers

For remanufactured turbochargers, DUO FLOW makes it possible to:

• verify the quality of the remanufacturing process
• validate components with previous service life
• reduce the risk of post-sale disputes and claims
• reduce dependence on operator experience

Summary

DUO FLOW is a complete solution for turbocharger verification, combining high-speed balancing and dynamic flow testing in a single process.

The result is more accurate performance validation that ensures:

• greater precision
• greater reliability
• reduced operating times
• higher final quality
