VTR 4 Series VTR 254 Turbine Casing For ABB Turbocharger

ABB Turbocharger / VTR 4 Series/VTR 254 Turbin Casing For Turbo Rebuild Parts

ABB / VTR series exhaust gas turbocharger design advantages:

The VTR..4 series of turbochargers is designed for two-strokelow-speed and four-stroke medium-speed, heavy-duty diesel and gas engines with ratings ranging from 700 kW to about 18,500 KW per turbocharger.The advantages are as following: 

• The VTR 4 series is capable of high pressure-charging, the pressure ratio from 3.7 even to 4.2.
• 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%.
