Common Gas Turbine Engine Failures
Common Gas Turbine Engine Failures; Where Do They Come From?
A gas turbine engine is like a delicate creature;
that is, although its appearance looks very industrial, it is sensitive to the smallest error, dust, temperature, or even fuel quality.
In this article, we want to tell you what failures occur most often and what their causes are?
1. Problems in the compressor
Common Gas Turbine Engine Failures The compressor is the heart of the gas turbine engine.
When this part fails, the entire engine fails and fails.
In answer to the question of why does a compressor fail?
It should be said for several reasons, including:
Ingress of dust and small objects, wear of blades
Incorrect installation or imbalance
And its symptoms can be said to be
Decrease in efficiency
Excessive vibration
Excessive fuel consumption
If the engine consumes a lot of fuel for no reason, the first place you should check is the compressor.
2. Incomplete combustion
Incomplete combustion means the fuel does not burn properly.This causes a drop in engine power and even damage to subsequent parts. The reasons for this are: Low fuel quality, faulty fuel injectors, low air pressure, what happens next? The answer to this question is that the engine is hard to start, excessive smoke, abnormal temperatures inside the combustion chamber.
3. Turbine blade breakage
Turbine blades operate under extremely high pressure and temperature, so they become fatigued or cracked after a while. The reasons for this include: Excessive heat, poor raw materials or very long operation, impact or foreign body entry, symptoms: Strange noises, sudden power loss, abnormal value, This is one of the most expensive and costly failures because replacing or repairing a turbine blade is a very difficult and laborious task. 4.Excessive temperatures
When the cooling system does not work properly, the temperature rises above the permissible limit and the engine goes into thermal shock
What are the reasons for this?
Clogged air passages
Contamination on the blades
Damaged temperature sensors
If this is not taken seriously, it can cause sensitive parts to melt!
Summary:
Common Gas Turbine Engine Failures
How to control these failures?
Regular periodic service
Always replace or clean filters
Use high-quality fuel
Install a monitoring system
A gas turbine engine is like a race car; if it is well taken care of, it will work for years, but if it is not maintained properly, it will be spent in a short time.
