Basically all the activities or anything in our lives, there must be advantages and disadvantages that are caused. And so is the pneumatic system.
These are the advantages and disadvantages of pneumatic systems:
Advantages
• Infinite source availability
Air is the most important thing in the pneumatic system, and as we all know, air is available in the world around us in unlimited quantities at all times and in all places.
• Easy channeling
Air is a substance that is easily passed or moved from one place to another through a small, long, sinuous tube.
• Temperature is flexible
Air can be used flexibly at various temperatures are required, through equipment designed for specific circumstances, even in very extreme conditions, the air was still able to work.
• Insurance
The air can be charged more safely than it is non-flammable and does not produce a short circuit (konsleting) or explode, so that protection against these two things quite easily, unlike the electrical system which could lead to konsleting fires.
Cleansed
The air around us tends to be cleaned without harmful chemicals, and can also be minimized or cleaned with some processes, so it is safe to use pneumatic systems for the pharmaceutical, food and beverage and textile industries.
• Power transfer and speed is very easy to set up
Air can move at speeds that can be adjusted from low to high or vice versa. When using a pneumatic cylinder actuator, the speed of the piston can reach 3 m / s. For pneumatic engines it can rotate at 30,000 rpm, while the engine turbine systems can reach 450,000 rpm.
• Can be stored
Air can be stored through the seat tube fed with excess air pressure. In addition, it can be installed so that the pressure limit or the safety of the system are safe.
• Easy to use
Air easily or directly used to clean surfaces such as metal and machinery, or indirectly, that is, through pneumatic equipment to produce certain movements.
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, lubricant tube, dryer, regulators, etc.
• Easy to filter
One of the properties of pressurized air is how to always occupy empty space and air pressure is maintained in hard work. Therefore, we need a seal so the air does not escape. Leakage of the seal can cause loss of energy. The pneumatic equipment must be equipped with airtight equipment to minimize compressed air leaks in the system.
• Noise potential
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 pipe. The solution is to put a muffler on each dump line.
• Easy to condense
Pressurized air condenses easily, 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.
