CCS Turbo Seal T- NA Series Inboard Plain Bearing Design Custom Size

T- MAN / T- NA series turbocharger design features:

T- NA series turbocharger sealing bush is the turbocharger replacement part for T- MAN / T- NA series turbocharger, which were developed comparatively simply with a cast axial turbine, which is suitable for heavy fuel oil engines, marine diesel oil engines, biofuel and gas operation enginess. T- NA series turbochargers are available for an engine power range from 1,650 kW to 24,500kW per turbocharger and with easy maintenace or overhaul.

• Axial flow turbine inboard plain bearing design;
• Lubricated by the engines lube oil system;
• Suitable for a wide variety of fuels, heavy fuel, diesel oil, biofuel and gas operation;
• Simple and durable design;
• Long service life；
• widely used in marine, power and industrial applications．

T- MAN / T- NA series turbocharger includes:

The function of turbocharger seals​:

The sealing devices of the exhaust gas turbocharger is divided into two types: gas seal and oil seal.

The function of the gas seal is to prevent leakage of compressed air at the compressor end and gas exhaust gas at the turbine end. A large amount of leakage of compressed air at the compressor end will reduce the boosting efficiency; leakage of the exhaust gas at the turbine end will cause the turbine power to drop, and high temperature gas leaking into the bearing housing will contaminate the lubricating oil and damage the bearing.

The function of the oil seal is to prevent leakage of lubricating oil in the booster bearing housing. Leakage of lubricating oil not only increases its consumption and affects bearing lubrication, but also causes the temperature of the gas to rise and even burn the turbine blades due to leakage of oil into the turbine inlet casing.

Therefore, a good sealing device is an indispensable part of the normal and reliable operation of the exhaust gas turbocharger.
