Conclusion: The annual output of 400000 tons of aluminum alloy requires about 100 to 110 cubic meters of compressed air per minute, and the total annual consumption is about 10 million to 11 million cubic meters.
How did this number come about. There is an actual project data for reference: the workshop with an annual output of 150000 tons of aluminum alloy ingots has a calculated compressed air load of 40 cubic meters per minute and an annual consumption of 3.82 million cubic meters. According to this ratio, the scale of 400000 tons is about 2.67 times that of it, so the gas demand is about 107 cubic meters per minute, and the annual consumption is about 10.19 million cubic meters.
Compressed air is mainly used in these places in aluminum alloy production: mixing and blowing refining in smelting process, sand blowing cleaning and pneumatic control in casting process, feed gas of nitrogen station (aluminum alloy smelting protection needs a large amount of nitrogen, while nitrogen making machine needs compressed air as raw material), and various pneumatic tools and instruments. Among them, the amount of nitrogen is very large. The annual nitrogen consumption of the first phase of the project alone is close to 50000 cubic meters, and the total of the two phases is 86000 cubic meters. This is only nitrogen, not compressed air itself.
Water-lubricated oil-free air compressors are very suitable in this scenario. Aluminum alloy castings have high requirements for gas cleanliness. The gas discharged from the traditional oil-injected air compressor will contaminate the surface of the casting. When the water-lubricated oil-free air compressor works, pure water is used instead of oil for lubrication and sealing. The discharged gas is completely oil-free, and because the cooling effect of water is better than that of oil, the exhaust temperature is only about 40 ℃, which belongs to isothermal compression. The gas production per unit horsepower is about 15% higher than that of a dry machine. Cooperate with the air-water separator and dryer to remove the moisture, the air pipe is clean and dry oil-free air, the casting quality is more guaranteed.
In the actual selection, it is recommended to match 110 cubic meters per minute, plus a margin of about 20% to deal with production fluctuations and pipeline leakage. That is to say, with a water-lubricated oil-free air compressor of about 130 cubic meters per minute, plus a cold dryer or a suction dryer for post-treatment, it is basically enough.
In the pharmaceutical industry, the choice of air compressor is a very particular link. When it comes to micro-oil air compressor, although it is a right-hand man in some industrial fields, in the field of pharmacy, which requires extremely high purity, it seems to be somewhat "weak".
Safety Operation Regulations for Air Compressors Before 1. Startup 1. Check whether each moving part is flexible, whether each connecting part is fastened, whether the lubrication system is normal, and whether the motor and electrical control equipment are safe and reliable. 2. Check the air compressor before operation
When selecting a compressor based on gas consumption, the following key factors need to be considered: Determine gas consumption: First, accurately calculate or estimate gas consumption, which includes the use of compressed air, the use of the process and the future development of space. The calculation of gas consumption shall be based on the equipment's
In PCB (printed circuit board) factories, the type of air compressor depends on the specific needs and configuration of the factory. Generally speaking, PCB factories will choose to use oil-free air compressors, mainly because of the high requirements for the purity of compressed air. In the PCB production process,
In the field of air compressors, Shanghai Grankering Group has won wide market recognition for its advanced water-lubricated oil-free screw air compressor technology, with its excellent performance and environmental protection characteristics. Shanghai Granklin Group's water-lubricated oil-free screw air compressor, using the first
Reciprocating compressor outlet oil content is an important index, it is affected by many factors. The following are some key points about the oil content at the outlet of the reciprocating compressor: Influencing factors: The working state of the compressor: The working state of the compressor will directly
There are significant differences between the air compressor integrated machine and the split machine in many aspects, which are mainly reflected in the structure, ease of use, application scenarios and maintenance costs. The following is a detailed analysis of the difference between the two: 1. structure difference one
To remove the moisture from the air compressor, the following strategies can be adopted: Pre-cooling using cold and heat exchange technology: Pre-cooling the hot compressed air just generated, which helps to reduce the moisture content in the air. By reducing the temperature of the compressed air, you can reduce
There is a close relationship between air compressor gas production and air consumption, but they are not completely equivalent concepts. The following is a detailed explanation of the relationship between the two: definition and measurement: gas production: refers to the pressure that the air compressor can produce in a unit of time.
The cleanliness of compressed air in the semiconductor workshop is extremely high, mainly due to the zero tolerance characteristics of small pollutants in chip manufacturing, packaging and testing processes. The specific requirements of the adaptation scheme of the water lubricated single screw air compressor in Gillanklin are as follows: 1. Core cleanliness
