เครื่องทำลมเย็น: หลักการ & การใช้งาน

Good air source quality is necessary for the laser cutting industry. If there are water mist and oil, they will be sprayed on the protective mirror surface. So it will seriously affect the transmission of the laser beam. Ultimately will also affect the cutting quality. The workpieces will have problems such as burrs and rough cutting surfaces. ในเวลาเดียวกัน, oil and water will adhere to the laser cutter. This affects aesthetics. More seriously, it may cause damage to the laser head.

We need to remove three types of compressed air pollutants in the laser cutting industry.

① Water —— Use a refrigerated air dryer and a desiccant dryer. Removes most of the water content in compressed air. Bring the pressure dew point to around -20 ถึง -40°C.

② Oil vapor —— Use a precision oil-removal filter. It can remove oil from compressed air.

③ Dust —— use the post-dust removal filter. It’s to ensure that dust does not enter the laser cutting equipment. Avoid dust contamination on optical lenses.

ดังนั้น, we recommend the following compressed air system: เครื่องอัดอากาศ + ถังเก็บอากาศ + refrigerant dryer + adsorption dryer + precision filters. ทางนี้, it can guarantee the air quality for laser cutting. To improve the efficiency and quality of laser cutting!

What’s PET bottle molding? Injection molding of thermoplastic resin. Get tubular plastic parison. หลังจากนั้น, please place it in a split mold while still hot. Immediately after the mold closing, introduce compressed air into the parison. Inflate the plastic parison against the inner wall of the mold. ในที่สุด, cool and de-mold. So we obtain various plastic bottle products.

In the blow molding industry, the working pressure of compressed air is relatively high. โดยทั่วไป, reach 3.0MPa or 4.0MPa. Under this pressure, many gaseous water and oil pollutants will accumulate. This causes defects in various blow molding products. It will cause pockmarks or dirt on the surface of plastic bottles. นอกจากนี้, it will also affect the stability of PET bottle stereotypes.

ดังนั้น, it is essential to use a refrigerant air dryer. It effectively removes moisture and impurities. And help PET bottles fully crystallize at the moment of setting. แน่นอน, we must use medium and high-pressure refrigerated air dryers here.

The textile industry is inseparable from air compressors. The rotary screw compressor is a significant power source for the production of textile enterprises. There are many production processes in the textile industry. The demand for air consumption in different processes is quite different. ดังนั้น, the demand for air compressors is also relatively large.

Air-jet looms are the equipment that uses the most compressed air. ในเวลาเดียวกัน, air-coated wire and texturing machines also require compressed air. And so do the drying and transportation of chips in the chemical fiber industry. These machines require a stable air supply. It also requires the compressed air to be dry, oil-free, and clean. Refer to the operating requirements of various air-jet looms. The quality indicators of the compressed air are mainly as follows:

① ประการแรก, remove the liquid water effectively. And remove as much gaseous moisture as possible. The pressure dew point should be below 10℃;

② ประการที่สอง, remove the oil vapors 0.8~1.0 μm;

③ ประการที่สาม, remove dust particles above 0.3~1.0 μm;

ดังนั้น, we have to install a refrigerated air dryer and precision filters. Use them to ensure the quality of compressed air. Only in this way it can guarantee the stability of textile production. ในเวลาเดียวกัน, it can reduce the harm to textile equipment products to a minimum standard.

Compressed air has wide applications in the food industry. ตัวอย่างเช่น, beer, monosodium glutamate, lactic acid, beverages, and food fermentation require it as a power source. All pneumatic components and solenoid valves also need compressed air.

We need it to control the filling, packaging, and bottling automation. The transportation, fermentation, and spraying of powdered substances also require completely pure compressed air.

If there contains oil or other impurities, it will cause pollution. In the food industry, there cannot be any minor contamination. มิฉะนั้น, it may bring physical hidden danger to consumers. On request, the air quality must meet the Class 2 standard in the food industry. นอกจาก, the compressed air dew point should be below -40°C.

So it would be best if you cleaned it first. The compressed air system includes an air compressor, เครื่องรับอากาศ, filters, dryers, เป็นต้น. The pressure dew point of a refrigerant air dryer can only reach +2°C to +10°C. It cannot meet the air quality requirements of the food industry. ดังนั้น, it must also add a desiccant air dryer. แน่นอน, a refrigerated air dryer is also necessary. มิฉะนั้น, it is impossible and difficult to meet the requirements.

ในขณะที่เราทุกคนรู้ว่า, the spraying industry relies heavily on compressed air. ดังนั้น, it is also very important to pay attention to the quality of compressed air. We generally have certain requirements for the aesthetics of the sprayed appearance. For example in car spray painting, if there are bubbles and pitting, it basically needs to be reworked. แน่นอน, spraying in different industries has different requirements for the moisture content of compressed air.

① Car Spraying And Metal Spray Paint

The requirements for automotive spraying are the highest. ประการแรก, there must use a refrigerated air dryer. But it also needs to install a desiccant dryer. อย่างไรก็ตาม, there is no need for a dryer in many car beauty shops. Because the air consumption is too small, using it is unnecessary.

Metal products generally require a smooth appearance. It is the same as the requirements for car spraying. It is not recommended to use only a refrigerant dryer for drying.

② Wood Product Spraying, Building Decoration

Most of the wood products are furniture spraying. Its requirements are not high. นอกจากนี้, architectural decoration, such as stair railings and wall spraying, do not have very high requirements for appearance. ดังนั้น, it only needs to use the refrigerated dryer as a separate drying machine.

③ Nano Spraying, Art Spray Painting

This is the high-end spraying industry. This type of spraying has high requirements for appearance aesthetics. And the spray material is relatively expensive. Rework costs are also high. ดังนั้น, it is not recommended only to use the refrigerated air dryer. In many cases, it is necessary to install an adsorption dryer.

In pharmaceutical factories, compressed air is also widely used. ตัวอย่างเช่น, filling machines and granulators of preparations need it. นอกจากนี้, pulping, filling, and packaging machines are also required it. There are two types of compressed air in the pharmaceutical industry: one is a general oil-lubricated compressed air system. It’s for the pneumatic components of the instruments. They do not come into direct contact with medicines. The other is an oil-free compressed air system. They come into direct contact with medicines. It is important to note that even oil-free air contains a lot of water and impurities.

แน่นอน, the latter is currently most used by drug manufacturers. To ensure the air quality, its purification requirements are stringent. Compressed air systems are subject to validation. Only in this way can we meet the production requirements and pass the GMP certification inspection. Air sources in the pharmaceutical industry should meet the ISO8573.1-2001 standard. นั่นคือ, the dew point should be at least -40°C. Solid particle sizes ≤ 0.1 ไมครอน. Oil content≤0.1mg/m³.

So we must use a refrigerated air dryer and a desiccant dryer to remove moisture. And it also requires the installation of precision filters. นอกจากนี้, their materials must be 304 สแตนเลส.
