ABB Martine Turbocharger RR Series Silencer for Ship Diesel Engine
RR series supercharger is mixed-flow turbocharger, which consists
of single-stage mixed-flow turbine and centrifugal compressor,
adopts inboard support roller bearing and centrifugal compressor,
adopts inboard support roller bearing and external lube oil supply
structure. There is no nozzle ring on the turbocharger. The major
casing can rotate freely within 0-360° according to installation
angel. Flow range of this series turbocharger is 0.6-2.5m3/s,
compression ratio range 1.5-3.0 and total efficiency higher than
80%. Single turbocharger can cooperate with 250-1500kw high speed
diesel engine and gas engine. RR turbochargers are used widely in
shipbuilding, locomotive, land power generation 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.
