IHI Turbocharger RH183 Filter Silencer For Ship Diesel Engine

IHI Turbocharger replacement part/IHI 183 Silencer/Filter for ship Diesel Engine

The function of turbocharger silencer:

As all knew, turbochargers have been extensively used in diesel engines to improve their performance. However, due to their operation at high speeds, turbochargers are susceptible to noise generation such as whine (narrow band) and whoosh (broadband). While unbalanced blades contribute to the former, the latter is due to turbulence. Such noise can be radiated from the structure, especially from the duct segment between the compressor and intercooler. The characteristics of turbocharger noise have been addressed that the compressor outlet was a major contributor to the overall intake system noise and experimentally demonstrated the effectiveness of a thicker wall and a resonator to reduce turbocharger noise that is a silencer could reduce both whine and broadband noise. (Reference from article "Design of a Multi-Chamber Silencer for Turbocharger Noise" by I. J. Lee, A. Selamet and H. Kim)

The features of IHI / RH series turbocharger:

IHI/RH series turbocharger consists of single stage turbine and centrifugal compressor. This series of turbocharger can be used to match high-speed diesel engine power 300-110kw. Inboard plain bearing is lubricated by the engine oil system. The blade wheel of the compressor adopts the back bend and tilt Angle. The overall efficiency of T/C is 60%-62%, with the maximum pressure ratio of 3.6. IHI/RH series turbochargers widely used in Marine generator, drilling and mining field. Its design features is as following:

· High reliability: Excellent bearing stability system, high quality oil sealing performance, low temperature resistance setting and strict quality management to ensure the reliability and excellent performance of IHI turbine.

· Superior performance: with the use of advanced aerodynamics design turbine blade, minimized mechanical losses and low inertia design, IHI turbine has superior performance in high flow rate, large range and rapid pressure response.

· Lightweight design: IHI's RH series is reduced in size and weight and maintains the strength necessary for the turbine.

· Wide application: IHI turbines are available in a wide range of models to provide customers with the widest range of applications.

IHI turbocharger types include:
