Factory compressed air standards are mainly related to pressure, temperature, humidity and quality. The following is a detailed summary of these criteria:
1. pressure standard
the pressure standard of factory compressed air is usually determined according to the specific application. In general, the pressure of compressed air for industrial use is usually between 0.7MPa and 1.0MPa. However, there is also a view that the normal range of the outlet pressure of the compressor is 0.7MPa to 1.2MPa. In addition, according to the relevant national standards, the normal pressure range of industrial compressed air is 0.6MPa ~ 0.8MPa. It should be noted that the specific pressure should be selected according to the actual needs of the factory and the specific application.
2. temperature standard
the temperature of the compressed air is also an important criterion. At room temperature (about 25 ° C), the temperature of compressed air will rise above 60 ° C during use. Therefore, it is necessary to cool the compressed air to prevent damage to equipment and pipelines caused by high temperature. At the same time, the national standard stipulates that the basic temperature of the compressed air of the air compressor should be controlled within 80°C.
3. humidity standard
the humidity of the compressed air is also an important parameter to be controlled. Excessive humidity may cause pipeline corrosion, equipment failure and product quality problems. National standards stipulate that the relative humidity of compressed air should be controlled within 50%.
4. quality standards
in addition to the pressure, temperature and humidity criteria mentioned above, the quality of the compressed air is also a key criterion. ISO8573 is a widely used compressed air quality standard, which specifies the content of solid particles, water vapor and oil in compressed air. For example, according to ISO8573 standards, the size of solid particles in compressed air is strictly controlled, and the water vapor content is also clearly required to prevent the appearance of liquid water. In addition, for the oil content, there are corresponding regulations to ensure the cleanliness and stability of compressed air during use.
To sum up, the standard of compressed air in the factory involves pressure, temperature, humidity and quality. These standards are designed to ensure the stability, reliability and safety of compressed air during use. When selecting and using compressed air, the factory should formulate corresponding standards according to its actual needs and specific applications.
Today, with the highly developed automation of food enterprises, compressed air has been widely used. For some special processes in the food industry, compressed air may also come into direct contact with the product. Like some special chemical areas, the air may have been polluted, such
The formula for calculating the oil content of air compressors in ppm(parts per million, parts per million) is not directly given because it involves the mass content of lubricating oil in unit volume of air. However, we can understand this plan through some indirect methods or transformation relationships.
The use of medical compressed air mainly includes the following aspects: Medical equipment power source: Medical compressed air is often used as a power source for various medical equipment, such as ventilators, pneumatic surgical tools, etc. It provides stable and reliable air pressure power, To ensure that medical equipment can
The air consumption of the punch is to calculate the volume of each air cylinder, multiply it by the number of actions per minute, add it all together, and add a margin of 20% to 30 to obtain the required air compressor size. The water lubricated air compressor because the output of the air does not contain oil, can keep the air system of the punch clean, reduce the failure, is a very good choice for the punch air supply.
The quality standard of compressed air for food blown film is that the total oil content is below 0.01mg/m3. Compressed air for food film blowing has a standard oil content of 0.01mg/Nm3 and a gas production of 10 Nm3/min. The cumulative oil content in one hour is 6mg and 180g a month.
The water-lubricated oil-free air compressor itself uses water for lubrication, cooling and sealing, the compression process is closer to the ideal compression state, and its energy efficiency is higher than that of other oil-free models. After matching with frequency conversion technology, the energy-saving advantage can be further enlarged under the working condition of gas fluctuation, frequent loading and unloading are not required, additional energy consumption loss is also reduced, and the overall operation cost will be lower.
In order to continuously provide 6bar (I. e. 0.6MPa) of air pressure, choosing the right air compressor needs to consider a number of factors, including the displacement, power and actual use requirements of the air compressor. Here are some recommended steps to consider and related information: 1. understand the basics of air compressors
The gas storage tank is a special equipment, and the 10-year warranty given by the manufacturer is actually the "recommended service life", which does not mean that it will be automatically scrapped in the 10th year and 1st day. For example, just like the recommended maintenance mileage of a car, it does not mean that the engine will break down immediately. The key is to look at the actual state.
The industry standards for medical air compressors mainly include the following aspects: Safety: Medical air compressors must comply with relevant national safety standards. Standards to be followed include ISO 7396-1, Air and Oxygen Piping Systems for Medical Institutions
Air consumption is a key consideration when selecting an air compressor. Air consumption refers to the air flow required by the compressed air system during production, usually measured in cubic meters per minute (m & sup3;/min) or standard cubic feet per minute (scfm). Root
