T- Turbocharger / T- RH Series Turbocharger Casing Includes Turbine Housing, Bearing Casing And Compressor Housing

T- / T- RH series turbocharger features:

T- / T- RH series turbocharger casings include turbine housing, bearing casing and compressor housing belongs to one part of T- / T- RH series exhaust gas turbocharger. T- / T- RH series turbocharger consists of single-stage mixed flow turbine and radial flow compressor. This series of turbocharger can be used to match high-speed diesel engine. Inboard plain bearing is lubricated by the engine oil system. A seal plate and seal ring located in compressor side in order to prevent the air and oil leaking. The turbocharging efficiency is 60%-62%, and its compressor pressure ratio up to 3.6. T-RH series turbochargers are widely used in automotive, heavy truck, construction, marine and industrial engine.

• Superior perforce: the special design for its compressor wheels and turbine wheels make the high flow rate, wide operating ranges and super response possible.
• Two types of journal bearing: semi-floating type and full-floating type, in order to prevent the shaft to move.
• Compact design: T-RH series is developed to reduce in size and weight, but maintain the necessary strength.

T- / T- RH series turbocharger casing (turbine housing, bearing casing and compressor housing) description:

The turbocharger includes turbine part, bearing part and compressor part, so the turbine housing, bearing casing and compressor housings cover and protect all the important parts safely in the turbocharger to ensure a premium perforce of the engine.

The turbine casing, bearing casing and compressor housing are made by cast iron. Some casings are water cooled which complicates the casting. Water cooled casings are necessary for turbochargers with ball and roller bearings with their own integral LO supply (to keep the LO cool). Modern turbochargers with externally lubricated journal bearings have uncooled casings.

A turbine housing (casing) includes a central aperture for containing a turbine blade assembly and directing exhaust gases past the turbine blades in a turbocharger. The turbocharger consists of a single stage impulse turbine connected to a centrifugal impeller via a shaft. The turbine is driven by the engine exhaust gas, which enters via the gas inlet casing. The gas expands through a nozzle ring where the pressure energy of the gas is converted to kinetic energy. This high velocity gas is directed onto the turbine blades where it drives the turbine wheel, and thus the compressor at high speeds (10 -15000 rpm). The exhaust gas then passes through the outlet casing to the exhaust uptakes.
