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.
