FLOW D Dynamic Flow Bench with Precision Flow and Oil Leak Test

The dynamic flow test represents an evolution over static flow testing, introducing a fundamental condition: the actual turbine rotation during the test.

This is possible thanks to an integrated lubrication system that:

• feeds the turbo with oil at approximately 5 bar pressure
• maintains the oil temperature around 50°C

The result is an extremely realistic simulation of operating conditions present on the vehicle.

Analyzed Parameters

In addition to data already detected in static flow testing, the dynamic system allows for a much more comprehensive analysis.

Parameters shared with static testing

Air flow rate entering the turbine (liters/minute)

Measurements taken in three conditions:

• open geometry
• intermediate position
• closed geometry

Additional parameters of the dynamic test

Thanks to turbine rotation, it is possible to acquire additional fundamental data:

• Rotation speed (RPM) detected by optical sensor measured at three operating points compared with target values in the database
• Air flow rate on compressor side measured in liters/minute represents the air flow actually sent to the intercooler

These data provide a complete view of turbo behavior, both on the turbine side and compressor side.

Operational Advantages

The main advantage of dynamic flow testing is the greater reliability of diagnostics.

More Precise Control

The combination of multiple parameters allows you to:

• objectively verify performance
• compare results with reference data
• identify any anomalies with greater accuracy

Ideal for Rebuilt Turbines

In the case of regenerated turbines, where not all components are replaced, dynamic flow testing offers a decisive advantage:

• allows validation of components with prior use
• provides objective feedback on their suitability
• reduces dependence on operator experience

In contrast, with static flow testing, some assessments remain partially linked to technical interpretation.

Summary

Dynamic flow testing allows you to move from theoretical verification to actual performance validation, ensuring:

• greater precision
• greater reliability
• greater control over the final result
