High Wear Resistance Turbocharger Rotor Assembly Uniform Structure

Seals are located at both ends of the bearing housing. These seals represent a difficult design problem due to the need to keep frictional losses low, the relatively large movements of the shaft due to bearing clearance and adverse pressure gradients under some conditions.

These seals primarily serve to keep intake air and exhaust gas out of the center housing. The pressures in the intake and exhaust systems are normally higher than in the turbocharger’s center housing which is typically at the pressure of the engine crankcase. As such, they would primarily be designed to seal the center housing when the pressure in the center housing is lower than in the intake and exhaust systems. These seals are not intended to be the primary means of preventing oil from escaping from the center housing into the exhaust and air systems. Oil is usually prevented from contacting these seals by other means such as oil deflectors and rotating flingers.

It consists of single stage mixed-flow turbine, centrifugal compressor, external engine lubricating oil system.
it can be matched with high-speed diesel engine and gas engine of 500-3000kw.
cooled & uncooled bearing casing design.
The constant pressure mixed turbine is used to increase the volume flow through the nozzle ring with the pulse application.
The compressor wheel adopts after sloping shunt blades and provide three different periods of pressure.
The overall efficiency of turbocharger is 62%-64%, the maximum pressure ratio is 4.5.
It is compact structure, easy to maintain and widely used in marine main engines, marine auxiliary machines, generating sets, railway locomotives and other application areas of diesel engines.

Turbocharger design features:

bladed shaft belongs to the turbocharger. The turbocharger is for large medium-speed diesel and gas engines, with a power output range from2,500kW to 12,500kW.

Turbine: The turbocharger is axial turbine for high efficiencies and high volume flow rates.
Compressor: The compressors 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 bearing assembly lubricated directly by the engine lube oil system, plain bearings can run up to 36,000 hours before being overhauled.

Brief introduction of Marine turbocharger:

The marine turbocharger, also known as exhaust gas turbocharger, is the main equipment in the diesel engine boosting system. It consists of a single-stage exhaust gas turbine and a centrifugal compressor. They are mounted on the same shaft to form the moving part of the marine turbocharger/exhaust gas turbocharger - the rotor. The function of the marine turbocharger/exhaust gas turbocharger is to use the diesel exhaust energy to drive the turbine to drive the compressor on the coaxial to increase the air pressure into the cylinder, so that the diesel engine power is greatly improved. The exhaust turbocharger approximately doubles the power of the diesel engine, but its weight is only increased 10%.
