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.
