Description
A scuba diving machine is commonly referred to as a Self-Contained Underwater Breathing Apparatus (SCUBA). It allows divers to breathe underwater by supplying compressed air or gas through a system of components.
Key Components of a SCUBA Diving Machine:
1. Air Tank (Cylinder):
Stores compressed air or gas mixtures like Nitrox or Trimix.
Made of steel or aluminum for durability.
2. Regulator:
Converts high-pressure air from the tank to breathable pressure.
Includes a first stage (connects to the tank) and second stage (mouthpiece for breathing).
3. Buoyancy Control Device (BCD):
Helps divers control their buoyancy underwater.
Allows inflation and deflation to ascend, descend, or stay at a specific depth.
4. Pressure Gauge:
Monitors the amount of air remaining in the tank.
5. Depth Gauge and Dive Computer:
Measures depth and dive time to ensure safety.
Prevents decompression sickness by tracking ascent rates.
6. Mask and Snorkel:
Provides clear vision underwater.
Snorkel is used for surface breathing to conserve tank air.
7. Fins:
Helps divers move efficiently through water.
Modern Advances:
Rebreathers: Recycle exhaled air by removing carbon dioxide and adding oxygen, extending dive times.
Full-Face Masks: Provide communication systems and enhanced protection.
