Low Impact Gas Turbine Shaft Professional Vibration Resistant Low Running Noise

Low Impact Gas Turbine Shaft Professional Vibration Resistant Low Running Noise

The turbocharger bearing system appears simple in design but it plays a key role in a number of critical functions. Some of the more important ones include: the control of radial and axial motion of the shaft and wheels and the minimization of friction losses in the bearing system. Bearing systems have received considerable attention because of their influence on turbocharger friction and its impact on engine fuel efficiency.

With the exception of some large turbochargers for low-speed engines, the bearings that support the shaft are usually located between the wheels in an overhung position. This flexible rotor design ensures that the turbocharger will operate above its first, and possibly second, critical speeds and can therefore be subject to rotor dynamic conditions such as whirl and synchronous vibration.

1. It consists of single stage mixed-flow turbine, centrifugal compressor, external engine lubricating oil system.
2. it can be matched with high-speed diesel engine and gas engine of 500-3000kw.
3. cooled & uncooled bearing casing design.
4. The constant pressure mixed turbine is used to increase the volume flow through the nozzle ring with the pulse application.
5. The compressor wheel adopts after sloping shunt blades and provide three different periods of pressure.
6. The overall efficiency of turbocharger is 62%-64%, the maximum pressure ratio is 4.5.
7. 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%.
