Construction machinery turbocharger
Construction machinery turbochargers are manufactured from aluminum and high-strength steel alloys to ensure increased air pressure and engine efficiency under heavy loads. Compressor blades are designed with hardness of 50–55 Rockwell C and temperature resistance up to 650 degrees Celsius, capable of rotating at 100,000 RPM. Turbo outlet pressure is set between 1.5 and 2.2 bar, and central bearings with clearance below 0.005 millimeters ensure smooth, vibration-free operation. Anti-corrosion and thermal coatings on the blades enhance turbocharger lifespan in harsh environments.
The weight of construction machinery turbochargers ranges from 15 to 50 kilograms depending on model, with mounting using grade 12.9 bolts. Lubrication is provided by engine oil at 5–7 bar, and cooling is performed via water or oil systems to control blade temperature. Housing and impeller design is optimized with CAD software and CFD analysis to improve airflow and increase volumetric efficiency up to 87 percent. Estimated service life under standard operating conditions exceeds 12000 hours.
