Radial Flow Design Turbocharger Turbine Casing Well Dynamic Behavior

Turbocharger is an integral umpart of the ship's marine engine as it reuses the exhaust gases in order to increase the overall efficiency of the engine. It consists of two parts – blower and turbine sides, which need equal attention while carrying out routine maintenance procedures.

Turbocharging is one kind of supercharging by using exhaust gas turbocharger. In which the energy in the exhaust gas expelled from the engine cylinder is utilized in driven in gas turbine, which is connected to a centrifugal air blower and air is supplied to scavenge air trunk.

There are many different types of casings that are manufactured from high quality materials in order to resist in the high strength and temperatures for the longer possible life.

The marine turbocharger is a brand new, which consist of single-stage turbine and centrifugal compressor. This series of marine turbocharger can be used to match high-speed diesel engine which power is 300-1100KW. The marine turbocharger is widely being used in marine, drilling and mining industry.

turbocharger turbine housing (also called turbine casing or gas admission casing) belongs to one part of exhaust gas turbocharger.
Turbocharger consists of mixed flow turbine and radial flow compressor. This series of turbocharger can be used to match high-speed diesel engine.

Inboard plain bearing is lubricated by the engine oil system. A seal plate and seal ring located in compressor side in order to prevent the air and oil leaking. The turbocharging efficiency is 60%-62%, and its compressor pressure ratio up to 3.6. turbochargers are widely used in automotive, heavy truck, construction, marine and industrial engine.

1. High performance floating bearings for minimized mechanical losses and optimized damping behavior
2. Integrated oil piping , sealing air and venting system
3. Compressor wheel change with basic tools and no need of rebalancing the complete rotor
4. Reduced noise emission and increased efficiency

turbocharger turbine housing (turbine casing or gas admission casing) description:

A turbine housing (casing) includes a central aperture for containing a turbine blade assembly and directing exhaust gases past the turbine blades in a turbocharger.

The turbocharger consists of a single stage impulse turbine connected to a centrifugal impeller via a shaft. 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.
