T- IHI / T- RH143 Turbo Bearing Bush turbo seal For Marine Turbocharger Parts

T- IHI / T- RH series marine turbocharger:

T- RH143 Turbo Bearing bush belongs to T- IHI / T- RH series exhaust gas turbocharger, which 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 performance: 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.

The definition of bearing bush:

A bush, also known as a bushing, is an independent plain bearing that is inserted into a housing to provide a bearing surface for rotary applications; bush is the most common form of a plain bearing. It’s commonly designed to be solid (sleeve and flanged), split, and clenched bushings.

Brief introduction of Marine turbocharger:

Marine turbocharger / Exhaust gas turbochargers operate at high speeds, high exhaust gas temperatures, high air and exhaust gas flow rates, and high flow rates. Generally, the pressure of the exhaust gas is 0.25-0.45 MPa, and the exhaust gas temperature is 500-600 °C. The speed varies with the size of the Marine turbocharger / supercharger. The maximum speed of the large-sized supercharger is 10000 r/min, and the maximum speed of the small-sized supercharger can reach 40,000~50000r/min. Therefore, the marine turbocharger/exhaust gas turbocharger is a precision machine.
