Air Power at Sea or Ground
The power is in the air! Well, I am not talking about aero planes or the military but on something we have taken for granted. It's about the air we breathe. Invisible to the naked eye, you can get a lot of power from it if you know how.
Do you know that the air compressor is a very important piece of machinery on board a diesel operated ship? It is the heart of the starting air system for the diesel electrical generators and the main diesel engine. Without these engines, everything comes to a standstill.
The compressed air that is stored at 25 to 35 bars in air reservoirs has the capacity to start the main engines for at least 13 times before it becomes too weak. The pressure in the compressed air is sufficient to push huge pistons and turn the crankshafts of engines so that enough momentum is created for the engine to start.
Below are some practices that engineers should observe when they are operating and maintaining air compressors:
Grit or dirt must be prevented from entering any part of the unit. As with any machines, these will give rise to numerous problems later. When opening any pipes, the ends need to be covered up to prevent dirt from entering the system. Any oil pipes need to be blown through with air. All air passages must be examined and cleaned, and blown through with high pressure air to remove loose material.
If crankcase oil is changed, clean the crankcase. Do not use waste that may leave lint because they can get trapped in the system. Never use any inflammable liquid to clean the crankcase.
Valves must be cleaned and examined for cracks, marks, or scratches. If found, the valves must be replaced, because if any small pieces from the valve were to break they can cause severe damage to the compressor.
The amount of oil must be checked at intervals. Too little of it will cause wear down of the parts. If too much, carbonizing of valves can occur, resulting in loss of compressor efficiency, and loss of cooler efficiency. Check on the oil condition. If unsuitable oil is used, it may emulsify with the water vapor contained in the air, resulting in loss of lubricating quality and wear down of parts. Unsuitable oil may also evaporate, condense and deposit at the cooler tubes resulting in poor heat transfer, which can lead to carbonizing of valves.
Keep records of the number of working hours so that oil can be changed at the correct intervals.
Engineers must take care of the compressors diligently, especially the cooling system. If the compressor becomes overheated, usually many other problems will occur.
Because of the overheating, carbonization of the valves and even tubes can take place. The latter will result in poor heat transfer and more overheating. The compressed air might become so overheated that even the valve springs may lose their elasticity and fail. In the worst case, the compressor may even explode due to heat, air and fuel present together.
Well folks, bring up your air power!
