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?
Die Feuchtigkeit in der Druckluft stammt hauptsächlich aus der Atmosphäre. Dies ist der natürlichen Luft eigen. Unabhängig von der Jahreszeit, the atmosphere has a certain relative humidity. Zusätzlich, nach Kompression oder Abkühlung, the water vapor in the air will become liquid. Dies beeinträchtigt die Qualität der Druckluft.
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.
Vor dem Betreten des Luftkompressors, Die Feuchtigkeit in der Luft besteht hauptsächlich aus Wasserdampf. Und es ist ungesättigt. Wie im Blatt gezeigt 1, die relative Luftfeuchtigkeit ist 69%, und die Temperatur beträgt 20°C. Nach der Komprimierung (7 Bar), Der Wasserdampf in der Druckluft wird durch die Kühlung des hinteren Kühlers des Luftkompressors gesättigt. Und 42% Es fallen 100 % flüssiges Wasser aus. A gas-water separator and storage tank can remove this liquid water. Der Rest 58% of water is in the compressed air as water vapor.
Wenn kein Luftkompressor-Trockner vorhanden ist, the direct use of compressed air will be bad for production. Deshalb, refrigerated and desiccant air dryers have become the preferred air treatment equipment.
Es gibt drei allgemeine Anforderungen an den Wassergehalt von Druckluft.
① The air compressor discharges compressed air. Wenn es einen Kühler gibt + Luftbehälter, then it can lower the temperature by 3 Zu 10 ℃. This can meet customers with low-quality air, wie Bohrinseln, Luftkanonen, usw.
② But most industrial enterprises generally have such requirement :10℃>Drucktaupunkt>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℃, and 70℃.
What Are The Specific Problems That Arise?
Der Luftkompressor gibt die Druckluft ab, aber es ist nicht sauber. There are many contaminants, wie zum Beispiel Feuchtigkeit, Staubpartikel, Öl, usw. They will enter the production process if they are not purified and dry. Darüber hinaus, Viele Schraubenkompressoren sind Ölkompressoren. This leads to many problems.
Production Capacity Decline
If there is no air dryer compressed air, Feuchtigkeit, and oil will clog and rust pneumatic equipment and tools. Dies führt zu einem langsamen Betrieb. Neben, Verstopfte Leitungen und Teile führen zu einem niedrigeren Druck. Und die Werkzeuge werden an Effizienz verlieren. In a long time, die Ausrüstung wird kaputt gehen. In schweren Fällen, Dies kann zu Produktionsausfällen führen.
Increase Product Defect Rate
Ein hoher Wassergehalt in der Druckluft führt zu einer erhöhten Produktausfallrate. Zum Beispiel, spray painting and electronic product processing. In Laser- oder Plasmaschneidmaschinen, Feuchtigkeit verunreinigt die Linsen unserer Schneidköpfe. So, it will directly affect the cutting efficiency.
Zusätzlich, various influence exists in the food industry. Bei der Verpackung und dem Transport von Lebensmitteln spielt häufig Druckluft eine Rolle. Auch, Druckluft kommt häufig mit dem Produkt in Berührung.
Wenn kein Luftkompressor-Lufttrockner vorhanden ist, then much moisture or oil can damage our food. Vor allem in der Trockenfutterindustrie, Es gelten strengere Anforderungen an die Luftfeuchtigkeit. ISO-Normen sehen unterschiedliche Klassen für die Druckluftqualität in der Lebensmittelindustrie vor. Different levels have different contents of solids, Wasser, und Öl.
Air Aerodynamic Loss
Wasser in der Druckluft führt zur Korrosion der Rohre. Dies führt zu Rohrverstopfungen. Darüber hinaus, mixing water, Öl, and dust can exacerbate blockages. Neben, in kalten Regionen, Durch das Einfrieren von Feuchtigkeit können Rohre einfrieren. Dann sinkt der Druck und die Druckdifferenz wird groß. Letztlich, it will affect the safety of production. Zusätzlich, it will lead to air leakage from the pipeline in serious cases.
Zur Wasserentfernung sind daher ein gekühlter Drucklufttrockner und ein Adsorptionsluftkompressortrockner erforderlich.
Increase Production And Maintenance Costs
Feuchtigkeit und Öl schädigen unsere pneumatischen Komponenten direkt. Neben, they will also corrode our equipment. Dann müssen wir die Ersatzteile durch neue ersetzen. Dies erhöht sowohl die Wartungskosten als auch die Produktionszeitkosten.
To improve compressed air quality, you must install precision filters to remove oil and water. Dann, install an air compressor air dryer to remove the water deeply. Dadurch wird der Taupunkt auf die Anwendungsanforderungen gebracht.
What Can Compressed Air Dryers Bring You
A compressor air dryer is a device used to process compressed air. It improves compressed air quality by removing moisture and other impurities from the air. Below are some of the main functions the air compressor dryer can perform.
Dehumidification
Compressed air often contains significant amounts of moisture, harming many applications. Compressed air dryers remove moisture from the air through technologies such as cooling, Adsorption, or membrane separation. This prevents moisture from corroding, icing, or other problems with equipment and processes.
