Pneumatic systems are designs that use pressurized gas to power machines and tools. There are many disadvantages and advantages of pneumatic systems.
Disadvantages:
• Requires the installation of air production equipment.
Compressed air must be well prepared to meet the requirements. Meet certain criteria, such as dry, clean, and contain the lubricant needed for pneumatic equipment. Therefore they require the installation of pneumatic systems are relatively expensive equipment, such as compressors, air filter, lubrication tube, dryer, regulators, etc.
• Easy to filter
One of the properties of pressurized air is how to always occupy empty space and the pressure of the air remains in hard work. Therefore, we need a seal so the air does not escape. Seal leaks can cause loss of power. The pneumatic equipment must be equipped with airtight equipment to minimize compressed air leaks in the system.
• Potential noise
Tire with open system, which means that the air that has been used will be thrown out of the system, the air comes out quite noisy and noisy, so it will cause noise, especially in the exhaust tract. The solution is to put a muffler on each dump line.
• Easy to condense
The pressurized air is easily condensed, so before entering the system it must first be processed to meet certain requirements, such as dry, have sufficient pressure and contains a small amount of lubricant to reduce friction in valves and actuators .
