Air 3.0

Question 1

Steps taken to prevent corrosion and erosion in cooling systems

Answer 1

1. Water flow control by pneumatic valve
2. Fresh water used in cooling system
3. Sacrificial anodes fitted in coolers

Question 2

Factors that affect efficiency of cooling systems

Answer 2

1. Air filters - blocked or dirty air filters prevent air from entering the compressor therefore reducing the output
2. Cooling arrangements - lack of cooling causes the cylinder walls to become hot. Air expands immediately on coming into contact preventing full discharge or air entering the chamber

3.Operation of cylinder valves - If the valves do not seat correctly , air will leak past and compression will be lost

4. Leaks - Air leaking from relief valves , pipe connections or joints will result in reduced output capacity.

5.Worn piston rings or cylinder liners- wear or damage to the piston rings or cylinder liners resulting in a loss of compression therefore reducing compressor output
