Key Technical Specifications & Features
-
Heavy-Duty High-Nickel Turbine Casing: Cast from high-nickel ductile iron to prevent structural cracking, warping, or exhaust gas leaks under continuous full-load digging and steep incline climbing.
-
Precision Factory-Calibrated Boost Control: Equipped with a precision-matched actuator mechanism that delivers exact boost modulation across varying engine load parameters, eliminating low-RPM sluggishness.
-
VSR Ultra-High-Speed Dynamic Balancing: The complete internal rotating assembly undergoes dynamic balancing on computerized Vibration Sorting Rigs (VSR) at full operational RPMs to eliminate micro-vibrations, ensuring smooth operation and extending journal bearing lifespan.
-
Inconel 713C Turbine Wheel: High-nickel turbine wheel metallurgy withstands continuous exhaust gas temperatures (EGTs) exceeding 850°C without blade tip erosion or deformation.
-
Advanced Internal Fluid Seals: Multi-piece piston ring oil seals prevent motor oil from passing into intake charge pipes or burning in the exhaust system.
