Key Product Features

1. 1:1 OEM Flange, Oil Inlet & Outlet Interface Design
   Totally consistent with original mounting dimension, pipeline thread and installation hole position, plug-and-play bolt-on installation without pipe or bracket modification, greatly shortening equipment maintenance downtime.
    
2. Precision High-Speed Dynamic Balanced Rotor Assembly
   Strict dynamic balance calibration effectively reduces axial vibration and running noise, prevents premature shaft sleeve abrasion and oil seal damage, avoiding turbo blue smoke oil-burning faults.
    
3. Heat-Resistant Cast Turbine Housing + Reinforced Alloy Impeller
   Withstands high exhaust temperature from heavy-load continuous operation, anti-thermal deformation and anti-fatigue fracture, suitable for long-time harsh industrial and marine working scenarios.
    
4. High-Temperature Resistant Dual Oil Sealing Structure
   Double-layer oil seal design effectively prevents lubricating oil leakage from compressor and turbine ends, eliminating engine blue exhaust smoke and oil consumption rising issues.
    
5. Strict Factory Quality Inspection System
   Each turbo passes air tightness test, boost pressure stability test, high-low temperature aging and vibration endurance tests to guarantee consistent stable supercharging performance.
    

Common Equipment Failures Solved

• Severe engine power shortage, slow acceleration and weak climbing performance under heavy load
• Excessive black smoke from exhaust, incomplete diesel combustion and sharply increased fuel consumption
• Turbo shaft seal leakage leading to engine burning oil, blue smoke emission and frequent oil top-up
• Abnormal whistling, grinding friction noise during acceleration caused by worn turbo bearings
• Turbo aging leading to unstable boost pressure, engine overspeed or protection shutdown under variable loads
