T- Turbo Seal / T- VTR Series Sealing Bush For Marine Turbocharger Parts

T- Turbo Seal / T- VTR Series Sealing Bush For Marine Turbocharger Parts

T- / T- VTR series marine turbocharger features:

T- VTR series turbocharger sealing bush is one part of T- / T- VTR series marine turbocharger with following features:​

• The T- VTR series turbocharger is developed to match with two-stroke low-speed and four-stroke medium-speed heavy duty diesel engine and gas engine.
• The engine power output range from 700 kW to 18,500 kW per each T-VTR turbocharger.
• The T- VTR series turbocharges is consisted of single-stage axial turbines and radial compressors.
• Easy maintained external bearings and low friction losses of the external antifriction bearings.
• The T- VTR 4 series is capable of high pressure-charging, the pressure ratio from 3.7 even to 4.2.
• Uncooled gas casings are available which can be an alternative to water-cooled gas casing.
• The rotor runs in spring-mounted roling-contact bearings, and each bearing has its own lubrication system and oil cooling system.
• The rotor shaft can be removed in four easy steps without distling the gas ifolds, or pulling of the compressor wheels.
• The T- VTR series is modular type of design, which ensures the turbine baldes, nozzle rings, comperssor wheels and diffusers with various casing configurations to be optimum matched with all engine types.
• Optimum engine perforce in part-load operation
• Connectors on the compressor side allow water cleaning during operation
• The T- VTR series turbochargers are widely used in marine propulsion engines, especially at part load, and in stationary power plants, on units burning heavy oil and in continuous operation.

T- / T- VTR turbocharger types include:

The functions for turbocharger seals:

The sealing devices of the exhaust gas turbocharger is divided into two types: gas seal and oil seal. A good sealing device is an indispensable part of the normal and reliable operation of the exhaust gas turbocharger. The sealing device is divided into three types according to the structure: contact type, piston ring type and labyrinth type. Piston ring seals are commonly used in small boosters as an oil seal. There are y types of labyrinth seals, axial and radial labyrinth seal for the turbocharger used as a gas seal. The smaller the gap between the gas seal sheets, the better the sealing effect. When a pressurized air is introduced from the compressor end to the gas seal, the sealing effect is enhanced.
