T- TPL77 Turbocharger Nozzle Ring For Diesel And Gas Engines Turbo Repair Parts

T- TPL77 Turbocharger Nozzle Ring For Diesel And Gas Engines Turbo Repair Parts

T- TPL-A series turbocharger design features:

T- TPL77 turbocharger nozzle ring is one part of T- TPL-A series turbocharger with the design features as below:

• The T- TPL-A series turbocharger is for large medium-speed diesel and gas engines,with a power output range ​​from 2,500kW ​​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:

T- TPL77 turbocharger nozzle ring description:

The turbine is driven by the engine exhaust gas, which enters via the gas inlet casing. The gas expands through a nozzle ring where the pressure energy of the gas is converted to kinetic energy. This high velocity gas is directed onto the turbine blades where it drives the turbine wheel, and thus the compressor at high speeds (10 -15000 rpm). The exhaust gas then passes through the outlet casing to the exhaust uptakes.

• The nozzle ring need to bear the extremely high temperature and high pressure, so it's very crucial for its material selection.
• The turbocharger nozzle ring is usually fabricated from a creep resistant chromium nickel alloy, heat resisting moly-chrome nickel steel or a nimonic alloy which will withstand the high temperatures and be resistant to corrosion.
• Furthermore, due to its function is to convert the exhaust gas into kinetic energy, the precision processing of the nozzle ring is highly deded.
