Ship Diesel Engine Turbo Housing ABB VTR Series Gas Inlet Casing Four Hole

ABB Martine Turbocharger VTR Series Gas Inlet Casing-Four Hole for Ship Diesel Engine

Products Introduction

VTR series supercharger is axial-flow turbocharger, which consists of single-stage axial-flow turbine and centrifugal compressor, and adopts outborad supportroller bearing and self-supply system of shaft-end centrifugal lube oil pump or gear lube oil pump. Its majo casing can rotate freely in 15°or 30° interval according to installation angle. Flow range of this series turbocharger is 0.5-18m3/s, compression ratio range 2.0-4.0 and total efficiency up to 62%. Single turbocharger can satisfy requirement of 250-10000kw high speed diesel engine. VTR turbochargers are widely used for marine main engines, marine auxiliary machines, land-based generating set and other application areas of diesel engines due to their high reliability, stability and applicability.
