When discussing industrial manufacturing or other applications requiring compressed air, air quality is an often overlooked but crucial element. We often focus on ensuring our compressed air systems provide enough pressure to drive equipment. But we rarely consider the humidity and purity of the air. This is where compressed air dryers become essential.
This article explores why compressed air dryers are indispensable equipment in many situations. We’ll look at when you might need a compressed air dryer. Whether you are an industrial manufacturer or use compressed air daily, this article will help you better understand why you should consider investing in a quality compressed air dryer. Let’s explore how this seemingly small but important device can have a profound impact on a variety of applications.
Where Does The Water in Compressed Air Come From?
La humedad en el aire comprimido proviene principalmente de la atmósfera.. Esto es inherente al aire natural.. Independientemente de la temporada, the atmosphere has a certain relative humidity. Además, después de la compresión o el enfriamiento, the water vapor in the air will become liquid. Esto afecta la calidad del aire comprimido..
In industrial air compressor applications, many users are very sensitive to moisture. Since we can’t eliminate the water before the air compressor, it must remove moisture in the compressed air treatment system.
Antes de entrar al compresor de aire, la humedad en el aire es principalmente vapor de agua. y es insaturado. Como se muestra en la hoja 1, la humedad relativa del aire es 69%, y la temperatura es de 20°C. Después de la compresión (7 bar), el vapor de agua en el aire comprimido se satura debido al enfriamiento del enfriador trasero del compresor de aire. Y 42% de agua líquida se precipitará. A gas-water separator and storage tank can remove this liquid water. El restante 58% of water is in the compressed air as water vapor.
Si no hay secador de compresor de aire, the direct use of compressed air will be bad for production. Por lo tanto, refrigerated and desiccant air dryers have become the preferred air treatment equipment.
Hay tres requisitos generales para el contenido de agua del aire comprimido.
① The air compressor discharges compressed air. Si hay hielera + receptor de aire, then it can lower the temperature by 3 a 10 ℃. This can meet customers with low-quality air, como plataformas de perforación, cañones de aire, etc..
② But most industrial enterprises generally have such requirement :10℃>punto de rocío a presión>0℃. This requires using an air compressor refrigerated dryer to remove the water vapor.
③ If the need for dew point ≤ 0 ℃, choosing a desiccant air compressor air dryer is necessary. The common dew point requirements for adsorption compressed air dryers are -20℃, 40℃, y 70 ℃.
What Are The Specific Problems That Arise?
El compresor de aire descarga el aire comprimido., pero no esta limpio. There are many contaminants, como la humedad, partículas de polvo, aceite, etc.. They will enter the production process if they are not purified and dry. Además, muchos compresores de aire de tornillo son de tipo aceite. This leads to many problems.
Production Capacity Decline
If there is no air dryer compressed air, humedad, and oil will clog and rust pneumatic equipment and tools. Esto provoca un funcionamiento lento.. Además, las líneas y partes obstruidas conducirán a una presión más baja. Y las herramientas perderán eficiencia.. In a long time, el equipo se romperá. En casos severos, esto puede conducir a un tiempo de inactividad de la producción.
Increase Product Defect Rate
El alto contenido de agua en el aire comprimido conduce a un aumento en la tasa de fallas del producto. Por ejemplo, spray painting and electronic product processing. En máquinas de corte por láser o plasma, la humedad contaminará las lentes de nuestros cabezales de corte. Entonces, it will directly affect the cutting efficiency.
Además, various influence exists in the food industry. El aire comprimido a menudo juega un papel en el envasado y transporte de alimentos.. También, el aire comprimido a menudo entra en contacto con el producto.
Si no hay compresor de aire secador de aire, then much moisture or oil can damage our food. Especialmente en la industria de alimentos secos., hay requisitos más estrictos para la humedad del aire. Las normas ISO tienen diferentes clases para la calidad del aire comprimido en la industria alimentaria. Different levels have different contents of solids, agua, y aceite.
Air Aerodynamic Loss
El agua en el aire comprimido corroerá las tuberías.. Esto conduce a la obstrucción de la tubería.. Además, mixing water, aceite, and dust can exacerbate blockages. Además, en regiones frías, la congelación de la humedad puede hacer que las tuberías se congelen. Entonces la presión cae y la diferencia de presión es grande.. Eventualmente, it will affect the safety of production. Además, it will lead to air leakage from the pipeline in serious cases.
Por lo tanto, necesita el secador de aire comprimido refrigerado y el secador de compresor de aire desecante para eliminar el agua.
Increase Production And Maintenance Costs
La humedad y el aceite dañarán directamente nuestros componentes neumáticos. Además, they will also corrode our equipment. Entonces tenemos que reemplazar las piezas de repuesto por otras nuevas.. Esto aumenta tanto el costo de mantenimiento como el costo del tiempo de producción..
To improve compressed air quality, you must install precision filters to remove oil and water. Entonces, install an air compressor air dryer to remove the water deeply. Esto trae el punto de rocío para alcanzar los requisitos de la aplicación..
