This module application advanced computation hydrodynamics (CFD) analyzed software NUMECA to carry on the turbocharger nozzle ring flow field analysis and the nozzle ring leaf blade profile simulation design, the module has applied the independent design new style air operated arc leaf blade. This is the air operated arc leaf blade's nozzle ring module, in domestic applies for the first time in the turbocharger.
The air operated arc leaf blade nozzle ring turbine wheel efficiency is higher than the symmetry leaf blade nozzle ring turbine wheel approximately high, peak efficiency 6.3%~6.9%. The air operated arc leaf blade's arc surface under the high temperature air current impact condition, as a result of its arc surface's rigid, is not easy to have the leaf blade distortion.
Module available in fuel gas temperature 400℃~850℃, pressure 0.01~0.35MPa, in stream velocity 0~400m/s operating mode.
The product assembly size and is suitable the type to see the next table:
| Specifications | Blades | The leaf-shaped | Blade length | Ye-type high | Installation disc diameter | Overall height after welding |
| 1065012 | 11 | Pneumatic | 17.5 | 5.3 | 83 | 18.3 |
