The turbocharger rotor shaft / rotor assembly / rotor complete consists of compressor impeller, blade shaf/turbine shaft / rotor shaft and partition wall complete.
The turbocharger rotor shaft is equipped with components such as a compressor and a turbine impeller, and has a complicated structure and a large weight. If the ship is parked for a long time, the turbocharger rotor will be bent and deformed due to the long-term non-operating self-weight, which will break the matching gap between the rotor and the casing, the gas seal and the casing, and the rotor will be lost. In severe cases, the rotor is difficult to rotate and the friction is severe. A large centrifugal force is generated during operation to cause the supercharger to vibrate.
Therefore, if the ship is suspended for a long time, attention should be paid to the management of the supercharger to prevent deformation of the rotor.
After a period of operation, the turbocharger is deformed or broken due to severe carbon deposits on the turbine blades; the compressor impeller, blade deformation or damage will change the rotor mass distribution, changing the original center of gravity of the rotor and destroying the original dynamic balance accuracy of the rotor produces severe vibration and the work is not stable.
The marine diesel 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%.
