We at Y.A. Marine Deals in all kind of MAN turbochargers, Used as well as new along with its New Spares as follows:
& other Spares on Requirements.
Main design features:
• One piece compressor wheel with spatially bent blades milled from high-tensile aluminum alloy material.
• The axial-flow turbine wheel is friction-welded to the rotor shaft which is short, achieving high rigidity and low mass.
• Flow-optimized turbine blades are mounted on turbine disc using the fir tree root principle. This design achieves positive connection between the turbine disc and the turbine blades which can be replaced individually without removing the rest.
• Inboard plain bearings with a floating bearing bush on the turbine side and an axial thrust bearing on the compressor side lubricated by the engine lubrication oil using the same oil circuit. The specific design promises a long service life (30.000+ hours) and simplifies maintenance because of the easy access to both turbine and compressor wheels and the inexistence of oil pumps, filters and coolers.
• Short bearing distance facilitating the precise rotor alignment.
• Single-walled, uncooled casings of waterless design minimizing corrosion of the turbine casing (no washing in HFO operation) and dissipation of process heat. As a result, no cooling water system is used and the casings are light.
Following NA series turbocharger:
MAN NA 29/S,
MAN NA 34/S,
MAN NA 40/S,
MAN NA 48/S,
MAN NA 57/T9,
MAN NA 70/T9.
• Compact, light and plain design facilitating the attachment to the engine and maintenance because of the few main components and promising increased operational reliability.
• Operational flexibility supporting both heavy and diesel fuel oil engine operation because of the high thermal tolerance (admissible exhaust gases of 650oC to the turbine side).
• Cost-effective supporting a wide output range with low operating costs and long service life.
