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?
Kelembaban di udara terkompresi terutama berasal dari atmosfer. Ini melekat di udara alami. Terlepas dari musim, the atmosphere has a certain relative humidity. Selain itu, setelah kompresi atau pendinginan, the water vapor in the air will become liquid. Ini mempengaruhi kualitas udara terkompresi.
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.
Sebelum memasuki kompresor udara, kelembaban di udara terutama uap air. Dan itu tidak jenuh. Seperti yang ditunjukkan pada Lembar 1, kelembaban relatif udara adalah 69%, dan suhunya 20°C. Setelah kompresi (7 batang), uap air di udara terkompresi menjadi jenuh karena pendinginan pendingin belakang kompresor udara. Dan 42% air cair akan mengendap. A gas-water separator and storage tank can remove this liquid water. Yang tersisa 58% of water is in the compressed air as water vapor.
Jika tidak ada pengering kompresor udara, the direct use of compressed air will be bad for production. Karena itu, refrigerated and desiccant air dryers have become the preferred air treatment equipment.
Ada tiga persyaratan umum untuk kadar air udara bertekanan.
① The air compressor discharges compressed air. Jika ada pendingin + penerima udara, then it can lower the temperature by 3 ke 10 ℃. This can meet customers with low-quality air, seperti rig pengeboran, meriam udara, dll..
② But most industrial enterprises generally have such requirement :10℃>titik embun tekanan>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℃, dan 70℃.
What Are The Specific Problems That Arise?
Kompresor udara melepaskan udara terkompresi, tapi itu tidak bersih. There are many contaminants, seperti kelembaban, partikel debu, minyak, dll.. They will enter the production process if they are not purified and dry. Lebih-lebih lagi, banyak kompresor udara ulir adalah tipe oli. This leads to many problems.
Production Capacity Decline
If there is no air dryer compressed air, kelembaban, and oil will clog and rust pneumatic equipment and tools. Ini menyebabkan operasi lambat. Di samping itu, saluran dan bagian yang tersumbat akan menyebabkan tekanan lebih rendah. Dan alat akan kehilangan efisiensi. In a long time, peralatan akan rusak. Dalam kasus yang parah, ini dapat menyebabkan downtime produksi.
Increase Product Defect Rate
Kandungan air yang tinggi di udara terkompresi menyebabkan peningkatan tingkat kegagalan produk. Misalnya, spray painting and electronic product processing. Dalam mesin pemotong laser atau plasma, kelembapan akan mencemari lensa pada kepala pemotong kita. Jadi, it will directly affect the cutting efficiency.
Selain itu, various influence exists in the food industry. Udara terkompresi sering berperan dalam pengemasan dan transportasi makanan. Juga, udara terkompresi sering bersentuhan dengan produk.
Jika tidak ada pengering udara kompresor udara, then much moisture or oil can damage our food. Terutama di industri makanan kering, ada persyaratan yang lebih ketat untuk kelembapan udara. Standar ISO memiliki kelas yang berbeda untuk kualitas udara terkompresi dalam industri makanan. Different levels have different contents of solids, air, dan minyak.
Air Aerodynamic Loss
Air di udara terkompresi akan menimbulkan korosi pada pipa. Hal ini menyebabkan penyumbatan pipa. Lebih-lebih lagi, mixing water, minyak, and dust can exacerbate blockages. Di samping itu, di daerah dingin, pembekuan kelembaban dapat menyebabkan pipa membeku. Kemudian tekanan turun dan perbedaan tekanan menjadi besar. Pada akhirnya, it will affect the safety of production. Selain itu, it will lead to air leakage from the pipeline in serious cases.
Sehingga dibutuhkan pengering udara tekan berpendingin dan pengering kompresor udara pengering untuk menghilangkan air.
Increase Production And Maintenance Costs
Kelembaban dan oli akan langsung merusak komponen pneumatik kita. Di samping itu, they will also corrode our equipment. Maka kita harus mengganti suku cadang dengan yang baru. Hal ini meningkatkan biaya pemeliharaan dan biaya waktu produksi.
To improve compressed air quality, you must install precision filters to remove oil and water. Kemudian, install an air compressor air dryer to remove the water deeply. Ini membawa titik embun untuk mencapai persyaratan aplikasi.
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, adsorpsi, or membrane separation. This prevents moisture from corroding, icing, or other problems with equipment and processes.
Purify
The air may contain particulate matter, grease, bacteria, dan kotoran lainnya. These impurities can cause problems in some sensitive applications. Air dryer compressed air can filter these impurities and provide cleaner and purer compressed air.
Improve System Efficiency
Dehumidification and purification of compressed air can improve the efficiency of compressors and pneumatic equipment. Dry air transports energy more efficiently, reduces corrosion on pipes and equipment, and reduces maintenance costs.
