Turbocharger description:

Turbocharger cover ring (also called turbine diffuser or gas outlet guide) belongs to the series. The series marine turbocharger is created for two-stroke, low-speed and four-stroke, medium-speed heavy-duty diesel engines. The engine power output is from 700 kW to 18,500 kW per turbocharger. Turbocharger has been widely applied to marine propulsion engines (esp. at part load), stationary power plants and units burning heavy oil and in continuous operation. The advantages are as following:

• Optimum engine performance in part-load operation

• the optimum match with all types and designs of engines due to the modular concept adoption

• Connectors on the compressor side allow water cleaning during operation

• External bearing

• Integrated lubrication system

• The rotor shaft can be removed without dismantling the gas manifolds, or pulling of the compressor wheels

• Low friction losses of the external antifriction bearings

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%.
