T- TPL73 Turbo Bearing For Axial Turbine Marine Diesel And Fuel Engines

TPL73 Turbo Bearing For Axial Turbine Marine Diesel And Fuel Engines

T- TPL73 turbo bearing belongs to a part of  T- TPL series exhaust gas turbocharger while T- TPL series are devided into T- TPL-A series and T- TPL-B series with the following features as below:

T- TPL-A series turbocharger design features:

• 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.

The function of T- TPL73 turbo bearing:

Turbo Bearings play an important role in turbochargers. They not only ensure safe and reliable high-speed rotation of the rotor, but also ensure that the rotor is fixed in the correct position.

Turbocharger bearings work under high temperature, high speed and light load conditions to ensure reliable operation of the bearings under working conditions. In addition to ensuring that the structural design, materials and manufacturing of the bearings to meet the requirements, good maintenance management is also critical important.
