General industrial control compressed air requirements
The quality of compressed air in industrial control systems is directly related to equipment operation stability and production safety. In order to ensure the reliable operation of various pneumatic components and actuators, compressed air must meet the following basic requirements:
1. Keep it dry
Moisture in the air is an invisible threat to corrosion of the air path system. Humid air may cause problems such as stuck solenoid valves and failed cylinder seals, just like immersing precision parts in “invisible sweat” for a long time. It is recommended to control the air humidity within a reasonable range through professional dehumidification devices to avoid the generation of condensed water.
2. Ensure cleanliness without impurities
Particles such as dust and oil in the air are like “sandpaper” in the air path, which will accelerate the wear of pipes and block precision filter elements. A multi-stage filtration system is needed to effectively intercept fine particulate pollutants, ensure that the cleanliness of the air entering the equipment reaches the “medical grade” standard, and avoid impurities causing chronic damage to the executive components.
3. Maintain constant pressure
Fluctuations in air pressure are like “irregular heart rhythm” in equipment operation, which may cause inaccurate movements of pneumatic components and even cause equipment to shut down. The compressed air pressure is required to continue to be stable within the allowable range of the equipment to avoid sudden increases and drops in pressure and provide a stable “power pulse” for the automated control system.
4. Achieve oil-free supply
Oil-containing air will pollute pneumatic components, form viscous oil scales, and increase the frequency of equipment maintenance. It is necessary to use an oil-free lubricating compressor or a deep oil removal device to ensure that the air flow is pure and oil-free, so as to avoid secondary pollution caused by oil stains to the processing environment and products, just like providing “pure breath” to the equipment.
Meeting the above basic requirements can significantly reduce equipment failure rates, extend the service life of pneumatic components, reduce the risk of unplanned downtime, and build a safe and reliable “air lifeline” for industrial control systems.
