IHI/MAN Martine Turbocharger NR/TCR Series Compressor Wheel for
Ship Diesel Engine
NR series supercharger is radial-flow turbocharger, which consists
of single-stage radial-flow turbine and centrifugal compressor,
adopts inboard support roller bearing and centrifugal compressor,
adopts inboard support roller bearing and external lube oil supply
structure. Flow range is this series turbocharger is 0.6-4.0m3/s,
compression ratio range 1.504.0 and total efficiency higher than
80%. Single turbocharger can cooperate with 250-2500kw high speed
diesel engine and gas engine. NR turbocharger are used widely in
shipbuilding, locomotive, land power station and petroleum drilling
industries. They are extensively applicable to in-land and coastal
transportation and fishing due to its high efficiency, small size,
light weight, favorable maintainability and serviceability,
adequate supply of spare parts.
