Pneumatics is derive from the Greek word, which means breath. In technology, it is a method of using pressurized air or gas and is a part of physics. Compressed air and compressed inert gas use to power the square type pneumatic cylinders system found widely throughout the industry.
Electric compressors use to power the air motors and cylinders along with other types of pneumatic devices in the center of the machine. Using an automatic or manual solenoid valve, a pneumatic system can either be low-cost or flexible, depending on the choice.
Furthermore, they can provide a safer alternative than actuators and electric motors. pneumatic devices also use in the mining, construction, and dental sectors.
The benefits of pneumatic systems
You can use pneumatics for air brakes, air compressors, vacuum pumps, barostats, dental drills, HVAC control systems, player pianos, pipe organs, pneumatic actuators, and pneumatic motors.
Pneumatic systems in fix installations such as factories use compress air since it is in abundant supply and can be obtained by compressing atmospheric air.
By removing the moisture in the common air and adding a small quantity of oil to the compressor, it ensures no corrosion will occur and that it also lubricates the mechanical components of the compressor.
Pneumatic power users in factories should be aware that poisonous leaks may occur, however, it is just air. Unlike nitrogen, the compressed gas used by stand-alone systems or smaller systems can pose an asphyxiation hazard.
Asphyxiation is a risk whenever any of these compressed gases use instead of air. Compressed oxygen may not cause asphyxiation, but it cannot use in pneumatic powered devices due to the possibility of fire and the cost, while it has no other advantages over the air normally use.
In small pneumatic tools and vehicles that have been fitte with fire extinguishers and soda streams, carbon dioxide may be use since the containers use to hold them are already in place.
It may be possible to get enough gas in a small container due to phase transitions between gas and liquid. In the use of carbon dioxide, the user should know that it is asphyxiating and may cause freezing if it is not vented properly. Both hydraulic and pneumatic systems use fluid power.
When it comes to square type pneumatic cylinders, it uses compressible gases like pure gases and air, while hydraulic uses incomprehensible liquids like oil. It is not uncommon for pneumatic devices to use pressures exceeding 80 pounds per square inch in industrial applications.
In hydraulics, 5000 psi is possible, but in specialized applications, 10,000 psi can be reach. Pneumatics have the advantage of being easy to control and design. Machines are simple to design, using only standard cylinders and a few other components.
Their only function is to turn on and off control that turns the system on and off. Pneumatic systems are more durable and do not require excessive maintenance. Having the ability to compress the gas easily prevents equipment damage from shocks.
A gas is capable of absorbing a lot of force, whereas a hydraulic fluid may transfer the force directly. It is easy to store compressed gas, and the machine may continue to run even when power is out. When compared to hydraulic oil, pneumatic does not pose too much fire risk. There is no risk of overloading with the new machine.
Benefits of Compressed Air
- The air is essential to the pneumatic system. As it is available throughout the entire world around us and it is not limit by time or place.
- Air is a substance that can easily pass through small pipes. It is also a substance that can move from one place to another in a flexible manner at different temperatures. Despite the fact that the equipment was design to operate under certain conditions. Air continues to function even under extreme conditions.
- It is safe: air is loaded in a safe manner, it is not flammable, does not cause a short circuit, and will not explode. Air protects against these two things, in contrast to an electrical system, which can cause a fire.
- The air use is clean and there is no potentially harmful chemicals use. If it is not clean, it can also be cleaned with some cheap method.
- Pneumatic systems are safe for pharmaceutical, textile, and food and beverage industries.
Nevertheless, pneumatic systems have some disadvantages as well
- The air producing equipment need to assembled: compress air has to be prepared so that it meets the requirements. Among the criteria are cleanliness and dryness, as well as the proper lubricant to use in pneumatic equipment. This is why there are some pneumatic systems that are extensive to install, such as regulators, dryers, lubricators, air filters, and compressors.
- The pressurized air leaks easily: its properties include being able to fill any empty space. It is difficult to maintain the air pressure. A seal must always be in place in order to prevent the air from leaking out. When a seal leaks, the energy is lost. In order to minimize air leaks within the pneumatic system, the equipment must be airtight.
- When pneumatic use an open system, the air is thrown out loudly, and the noise is usually found in the exhaust system. Every dump line will have a silencer to solve this problem.
- The air can easily be condens when it is under pressure and it just needs to process to meet new requirements like being dry or adding lubricants to reduce friction on actuators and valves.
A pneumatic cylinder, also known as a pneumatic actuator, is use to produce linear or rotary motion and force for automated systems, machines, and processes, such as those found in the industry.
Airmax Pneumatics Ltd offers various types of pneumatic components and they are an expert manufacturer of pneumatic cylinders. They offer round body and square type pneumatic cylinders in various strokes and ranges. Compress air has several advantages over the traditional method of power, including the fact that it is portable, quiet, and can produce in any place. While there are a few disadvantages to compress air, the most common issue is easily overcome.
