T- TPL-77 series turbocharger design features:

T- TPL77 type turbocharger belongs to T- TPL-A series. The T- TPL-A series turbocharger is for large medium-speed diesel and gas engines, with a power output range ​​from2,500kW ​​to ​12,500kW.

• Turbine: The T- TPL-A turbocharger is axial turbine for high efficiencies and high volume flow rates.
• Compressor: The T- TPL-A comressors ensure the high volume flow rates which allow optimized matching to different engine applications. Its single-piece, splitter-bladed aluminum alloy wheels with backswept blades ensure high efficiencies and wide compressor maps. its pressure ratio is from 4.2 up to 5.0 based on different design.
• Bearing: The T- TPL-A bearing assembly lubricated directly by the engine lube oil system, plain bearings can run up to 36,000 hours before being overhauled.
• Casing: The T- TPL-A casings is optimized for 4-stroke engines application, include integrated waste gate flanges, temperature and pressure measurement connections. All-round insulation minimizes the turbocharger noise level and casing surface temperature.
• It's widely used on diesel marine engine as well as gas engines.

T- TPL-A Series includes:

Brief introduction of Marine turbocharger:

Marine turbocharger/Exhaust gas turbochargers operate at high speeds, high exhaust gas temperatures, high air and exhaust gas flow rates, and high flow rates. Generally, the pressure of the exhaust gas is 0.25-0.45 MPa, and the exhaust gas temperature is 500-600 °C. The speed varies with the size of the Marine turbocharger / supercharger. The maximum speed of the large-sized supercharger is 10000 r/min, and the maximum speed of the small-sized supercharger can reach 40,000~50000r/min. Therefore, the marine turbocharger/exhaust gas turbocharger is a precision machine.
