Where do car factories need compressed air?

There are quite a lot, the power supply of stamping equipment, spraying equipment is also used, and pneumatic instruments are also needed.

Where else does air be used in our lives?

Taiwan DPC answers for you: the use of compressed air has been basically popularized in every factory, so what problems will arise in use? Common problems are compressed air leakage and equipment damage and production process impact caused by substandard quality.

The problem of compressed air leakage is very important, although it is inexhaustible, but the electrical energy used for its compression cannot be ignored, and a small leakage hole with a diameter of 1mm can cause a loss of up to about 3525 kWh of electricity per year.

In fact, basically every factory has had the problem of compressed air leakage, but it was discovered sooner or later. In order to prevent compressed air leakage, it is necessary to ensure the quality of the pipeline and the perfection of the compressed air purification system, and the compressed air that meets the quality standards will not corrode the pipeline.

When it comes to leaks, leaks in a plant typically account for 10 to 30 percent of the gas supply, and can be as high as 50 percent in a poorly managed plant. Sometimes there are 20,000 leaks in an automobile assembly shop, and more than 90% of the leaks come from aging or broken parts in the use of the equipment. To the point of being particularly serious, site managers far underestimated the damage caused by the leak.

For example, a leaking hole with a diameter of 1 mm in the air pipe at the supply pressure can cause a loss of about 3,525 kWh of electricity per year.

Reasonable configuration and operation of the compressor are very important to save electricity. In general, in order to make the output pressure fluctuate small, many compressors use suction valve adjustment. In the absence of gas supply, this method still needs to consume 40% of 70% of the rated power, which is a serious waste.

To this end, the introduction of frequency conversion control, number control, and the use of energy-saving monitoring system in the air compressor room are very effective in reducing electricity. These are largely ignored in the actual operation of the plant, and ensuring pressure becomes the only requirement for compressor management in most plants.

Due to the uncertain pressure loss in the pipeline, the flow peak in the start-up of the equipment, etc., the supply pressure of the compressor is sometimes higher than the pressure required on site. For every increase in the terminal equipment, the power consumption of the compressor increases by 4% to 8%, which is a huge energy cost. Sometimes the pressure on the whole system is increased due to the high requirements of a few machines, which is extremely unreasonable in terms of energy use configuration.

In the process of using compressed air, we must pay attention to the problem of compressed air leakage, as the second largest power source of productivity, the cost can not be ignored.

If the compressed air leaks, it will become air, and there is no harm. Unless you're ultra-high-pressure.

1. The main uses of the power industry: compressed air system for instrumentation, compressed air system for ash removal, compressed air system for factory miscellaneous use, water treatment including boiler make-up water treatment and industrial wastewater treatment system, and there will be compressed air system for equipment power in hydropower station. Second, the main use of chemical fiber industry:

The cotton spinning industry mainly uses clean compressed air as the power source, which has high requirements for oil content; The chemical fiber industry is mainly used for instrument gas and wire suction gun, and printing and dyeing is mainly used for power and instrumentation. 3. Light industry 1. Food and beverage: non-contact, indirect contact and direct contact with gas without contact

The scroll compressor can provide the air source, such as the direct contact between the cleaning of locust cans and beverage bottles: such as raw material mixing, fermentation, etc., which has high requirements for oil content, and it is necessary to deodorize the compressed air. 2. Pharmaceutical industry:

Non-contact is mainly power execution and instrument gas, direct contact due to the large amount of gas and stable victory, while requiring high air quality, generally centrifugal type, if the gas volume is not very large, you can choose a scroll machine plus a post-processor, or an oil-free screw. 3. Cigarette industry: compressed air is the main power source in addition to electricity, which is generally used in wire injection machine equipment, cigarette rolling, splicing and packaging equipment, and is also used with instruments, power execution, and equipment cleaning.

4. Rubber and plastic products: mainly used for power execution and instrument gas, and plastics are also used in the bottle blowing process. Fourth, the metallurgical industry:

The metallurgical industry is divided into iron and steel industry and non-ferrous metal smelting and production industry 1, iron and steel industry: let if it is power execution, instrument gas, purge instrument 2, non-ferrous metal smelting and manufacturing: mainly used for power execution, instrument gas, spraying 5, waterworks are mainly used for power execution.

Compressed air is generally used in factories, and air compressors are generally used.

What you said is demanding, I'm afraid the hospital, I don't know what equipment to use.

I know Shanghai Kaiboer Gas Technology ****, they are specialized in the production of compressed air dryers, especially their modular dryers and integrated air compressor system, which is very good.

After the free air in the atmospheric environment is compressed by the air compressor, the harmful substances such as water vapor, dust, oil mist and so on are sent into the pneumatic devices and instruments with the compressed air, and the high-temperature, high-humidity and high-pressure airflow will cause serious corrosion and pollution to the expensive pneumatic devices, instruments and pipelines, which will not only cause equipment and personal accidents due to the inaccuracy of the instruments and devices, but also seriously affect the quality of drug production. There are several risks associated with the DPC reminder:

1) the risk of non-compliance with regulatory requirements;

2) the risk of contaminating the product;

3) The risk of equipment and personal safety accidents.

According to the quality risk assessment, the risk level of the pharmaceutical compressed air system is high risk, and the compressed air must be further purified and dried (equipped with dryers and filters) to remove water vapor, dust, and oil mist to meet the production requirements.

The oil and water contained in the compressed air of the air compressor will be mixed into the production process, resulting in impure drugs and affecting product quality.

Take Kobayashi Pharmaceutical as an example: two oil-free vortex XA-8 + refrigeration dryer + precision filter + stainless steel pipeline.
