T- TPS Series Turbocharger Bearing Housing For Marine Diesel Engines
T- TPS Series Turbocharger Bearing Housing For Marine Diesel Engines
T- TPS series marine turbocharger features:
T- TPS series turbocharger bearing housing (also called bearing casing or bearing pedestal) is made by cast iron and which is one part of T- TPS series exhaust gas turbocharger. T- TPS series exhaust gas turbocharger has the design features as following:
- It consists of single stage mixed-flow turbine, centrifugal compressor, external engine lubricating oil system.
- it can be matched with high-speed diesel engine and gas engine of 500-3000kw.
- cooled & uncooled bearing casing design.
- The constant pressure mixed turbine is used to increase the volume flow through the nozzle ring with the pulse application.
- The compressor wheel adopts after sloping shunt blades and provide three different periods of pressure.
- The overall efficiency of turbocharger is 62%-64%, the maximum pressure ratio is 4.5.
- It is compact structure, easy to maintain and widely used in marine main engines, marine auxiliary machines, generating sets, railway locomotives and other application areas of diesel engines.

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%.
When the diesel-exhaust turbocharger combination is in operation, the marine turbocharger/exhaust gas turbocharger is prone to failures such as turbine casing corrosion, bearing damage, blade damage, gas seal damage, and supercharger vibration. The daily good maintenance agement can reduce these failures.
