Semiconductor equipment compressed air plant requirements are the core elements to ensure chip manufacturing accuracy and product yield, from the gas purity, dryness, stability and system reliability four aspects of the establishment of strict standards:
1. Gas purity control
semiconductor production has zero tolerance for oil pollution, and compressed air must meet the "oil-free and dust-free" standard. Through the water-lubricated single screw compression technology, the traditional lubricating oil is replaced by pure water, and the risk of oil pollution is eliminated from the source. With the multi-stage precision filtration system, particles above 0.01μm can be effectively removed to ensure that the solid impurity content in the gas is less than 0.001 mg/m & sup3;, which fully meets the gas demand of semiconductor clean room.
2. Dryness depth guarantee
the water vapor content of the compressed air shall be controlled to an ultra-low dew point level. Adopting the combination scheme of adsorption drying device and freezing dryer, the dew point of gas pressure can be stably reduced to below -70 ℃, so as to avoid the risk of corrosion or short circuit caused by condensate water on the inner wall of the pipeline to precision equipment. Supporting dew point sensor real-time monitoring to ensure that the dryness continues to meet the standards.
3. Pressure stability requirements
semiconductor equipment is sensitive to the pressure fluctuation of compressed air, and the pressure fluctuation should be controlled within ± 0.01MPa. By configuring the gas storage tank and intelligent pressure regulating valve, the peak fluctuation of gas consumption can be buffered; the frequency conversion control technology is adopted to make the output pressure of the compressor match the terminal demand in real time, so as to avoid the impact of excessive pressure on the equipment.
4. System reliability design
Application Value of Granklin Water Lubricated Single Screw Compressor
relying on the precision meshing technology of single screw and star wheel, combined with the natural cleaning characteristics of water lubricating medium, it provides continuous and stable high-quality compressed air for the semiconductor industry. Its oil-free design eliminates the risk of oil pollution. The intelligent control system can accurately adjust the output pressure. With the deep drying device and high-efficiency filtration system, a complete clean air solution is built to provide reliable gas power guarantee for chip manufacturing.
In the process of using the screw air compressor, some factories will have insufficient gas supply. In fact, the selection of the machine, air leakage, gas production standards, machine wear and other aspects may produce insufficient gas supply, resulting in the production workshop equipment can not operate normally.
Medical air compressors play a vital role in the medical field. It mainly provides high-quality compressed air for medical scenes such as medical equipment and operating rooms. The following are the main functions of medical air compressors: 1. provide power and support for medical equipment
In Jiangsu, many enterprises are faced with the challenge of choosing efficient and reliable oil-free air compressors. Among the many brands, Shanghai Grankering Group has become a large number of enterprises with its excellent technical strength and product quality, especially its water-lubricated oil-free air compressor products.
Screw air compressor start and stop intermittent only 30 seconds may be caused by a variety of reasons. First, this intermittent work may be related to changes in load demand. When the load demand fluctuates or changes in a short period of time, the screw air compressor may start according to the demand.
Nitrogen is widely used in the electronics industry, mainly as a protective gas, clean gas and process gas, and its purity usually needs to reach more than 99.999 percent to meet the stringent requirements of the electronics industry for product quality. The following is the specific application of nitrogen in the electronics industry and
Screw machine explosion-proof mainly need to consider the following aspects: First, due to the unique structure and working principle of the screw machine, it has explosion-proof requirements. For screw machines working in flammable and explosive environments, their motors need to meet explosion-proof requirements. Common
The hospital is a place with very high requirements for the air environment. High-quality oil-free air can be applied to the hyperbaric oxygen chamber treatment in the hospital and other medical equipment. Granklin oil-free water lubrication air compressor, suitable for various applications, including medical, pharmaceutical air cleanliness requirements are very high.
View detailsThe quality standard of compressed air in clean workshop and the adaptability of granklin air compressor are analyzed. As a production site with high requirements for environmental cleanliness (such as electronic component manufacturing, pharmaceutical production, precision instrument assembly, etc.), the quality of compressed air in clean workshop needs to meet strict requirements.
Air compressor does not drain will have a wide range of effects, including the following: 1. on the quality of the gas 1. increase in water content: air compressor at work will produce a lot of water vapor, these water vapor in the storage tank in the cold condensation into water. If not timely drainage, condensate
