Upgraded Turbocharger Bearing ISO Certification Fully Automatically Balanced

Upgraded Turbocharger Bearing ISO Certification Fully Automatically Balanced

• The compressor wheel / compressor impeller is of aluminium alloy or the more expensive titanium.
• Manufactured from a single casting it is located on the rotor shaft by splines.
• Aluminium impellers have a limited life, due to creep, which is dictated by the final air temperature.
• Often the temperature of air leaving the impeller can be as high as 200°C.
• The life of the impeller under these circumstances may be limited to about 70000 hours.
• To extend the life, air temperatures must be reduced. One way of achieving this is to draw the air from outside where the ambient air temperature is below that of the engine room.
• Efficient filtration and separation to remove water droplets is essential and the impeller will have to be coated to prevent corrosion accelerated by the possible presence of salt water.

Turbo Bearing / turbocharger bearings play an important role in turbochargers. They not only ensure safe and reliable high-speed rotation of the rotor, but also ensure that the rotor is fixed in the correct position. Therefore, the reliability of the bearing is extremely relevant to the normal operation of the supercharger and the diesel engine. Turbocharger bearings are divided into rolling and sliding, marine superchargers mostly use rolling bearings, in addition to thrust bearings.

Marine turbocharger's features:

Turbo Bearing belongs to exhaust gas turbocharger, which is a axial-flow turbocharger with wide application range of two-stroke and four-stroke engines.

• For engine power output range from 2000 to 30000 kW per turbocharger;
• Axial flow turbine inboard high performance plain bearing design;
• Whispering silencer with air filter;
• Low-noise, Easy maintenance compressor wheel due to it special fastening method;
• Uncooled bearing casing;
• Easy access to thrust bearing;
• Integrated sealing air, oil pipe and venting systems;
• High efficient diffuser;
• Long-life and adjustable nozzle ring;
• High efficiency of turbine blades is designed to be possible to omit the otherwise usual damping wire in the blade ring both for 2-stroke and 4-stroke engines;
• Suitable for heavy fuel, diesel oil, biofuel and gas operation;
• widely used in marine, power and industrial applications of diesel-powered and gas-powered engines．
