Unreasonable operation, long operation, lack of maintenance and maintenance are the root cause of the failure of gas turbine. To strengthen the maintenance and repair of the unit is a key factor in maintaining the normal operation of the unit, China today is to introduce factors affecting the life of gas generator:
1, the fuel is not pure, easy to cause the nozzle carbon burn; piston top carbon carbon combustion engine valve seat, sealing system bad dynamic performance decline;
2, the working environment is poor, such as multi dust, etc, easy to cause air filter plug, the engine heat sink blocked, resulting in high temperature engine;
3, the engine is cold not hot, sudden throttle, lubrication system didn't work properly, causing rapid wear of engine parts;
4, the quality of lubricating oil is not up to the standard, the quality of lubrication can not meet the engine's work needs, resulting in early wear of the engine;
5, the engine for a long time, overload fatigue, resulting in excessive wear and tear of the engine parts;
6, not on time maintenance.
The factors that affect the life of the gas turbine are various, and the introduction may not be comprehensive, but it includes most of the reasons.
