🛠️ Main Air Compressor System Overview
The main air compressor supplies high-pressure air to the main air reservoir, where it is stored and used to start diesel engines. The air from this reservoir is passed through a pressure-reducing valve to provide low-pressure air for various other systems, such as the driving air motors for the gangway.
🌬️ Control Air Compressor and Its Role
The control air compressor supplies low-pressure air to the control air reservoir, where it is stored for use in control systems. The system also includes an air dryer to remove moisture completely, ensuring the air remains dry.
🔗 Interconnecting Valve for Air Supply
An interconnecting valve links the control airline with the service airline, providing low-pressure air to control systems during maintenance operations on the control air compressor.
🚨 Emergency Air Compressor Function
The emergency air compressor operates independently of the ship's main power system and supplies air to the emergency air reservoir. This air is used to start generators in case of power failures or emergencies, ensuring backup power supply.
