Q: What is the difference between a cold dryer and a suction dryer?
Answer: The working mode of the cold dryer is different from that of the suction dryer. The cold dryer condenses the moisture in the air by reducing the air temperature to obtain dry compressed air.
The suction dryer uses the principle of pressure swing adsorption. When wet air passes through the adsorbent, moisture is adsorbed by the adsorbent to obtain dry air.
The pressure dew point is also different: the pressure dew point of the cold dryer is 2~10°C; the pressure dew point of the suction dryer is -20 ~-70°C.
Refrigerants (R22, R600, R134a, etc.) are used for cold dryers, and adsorbents (molecular sieves, activated alumina) are used for suction dryers.
For medicine, food, semiconductor, chemical industry, fermentation and other industries, oil-free and clean compressed air must be the first choice. Oil-free oil-free screw air compressor, water-lubricated oil-free screw air compressor, oil-free scroll air compressor and oil-free centrifugal air compressor are common oil-free.
In the case of permanent magnet variable frequency screw air compressor which is good to use (commonly used single-stage compression screw machine), the permanent magnet variable frequency air compressor is often unfamiliar with the equipment of permanent magnet variable frequency air compressor and does not know what brand of permanent magnet variable frequency compressor to choose.
There are many types of air compressors. If they are divided into two types according to the lubricating oil method: one is an oil-free air compressor and the other is an oil-lubricated air compressor. These two kinds of air compressor equipment have their own advantages and disadvantages. Today we will analyze the advantages of oil-free air compressor.
Compressed air can be pressurized, cooling, adsorption and other methods to remove the water vapor, and can be through heating, filtration, mechanical separation and other methods to remove liquid moisture. Refrigerated dryer is a kind of equipment that cools the compressed air to remove the water vapor contained in it and obtain relatively dry compressed air. The rear cooler of the air compressor also uses cooling to exclude the water vapor contained therein. Adsorption dryer is the use of adsorption principle to remove the water vapor contained in compressed air.
Air compressor is very common in our daily work, mainly used in pharmaceutical manufacturing, food processing, industrial pneumatic equipment, painting, textile, industrial and mining equipment and so on.
View detailsWhat air compressor is good for bottle blowing machine? Each industry has different pressure requirements for air compressors, and different bottle blowing machines are the same. What air compressor is good for bottle blowing machines? Granklin air compressor manufacturers recommend using screw-type medium pressure oil-free air compressors.
View detailsThe food industry should use environmentally friendly oil-free screw air compressors. The main engine of the domestic oil-free screw air compressor is manufactured by itself. Shanghai granklin is currently a high-quality choice for food, pharmaceutical factories and tap water. It also
Q: What is the difference between a cold dryer and a suction dryer? A: The working mode of a cold dryer is different from that of a suction dryer. The cold dryer condenses the moisture in the air by lowering the air temperature to obtain dry compressed air.
All the time, is the quotation of high air compressor? Then how to effectively reduce the maintenance cost of air compressor? 1. Ensure the quality of equipment parts The quality of equipment parts can also determine the quality of air compressor, and can improve the performance of equipment.
Permanent magnet frequency conversion air compressor has become a hot spot and bright spot in the industry due to its energy-saving and high-efficiency characteristics. The original energy-consuming air compressor on the market is gradually being replaced or replaced by permanent magnet frequency conversion air compressor, which can directly bring users 20%-40% cost savings.
