Electricity is one of the most important energy of a country, but also the national economy and the lifeblood of everyday life. Whether the use of any form of power generation, power plants are inseparable from the compressed air. According to the different types of power generation industry, on different occasions, should choose different levels of air quality. Refers to different types of so-called power industry is divided into thermal power stations, water power stations and nuclear power stations. Refers to the so-called different occasions in the same station has different occasions using compressed air. Since there is so much attention to the use of compressed air, the following training for everyone classification introduced by Wuhan screw air compressor systems in the power industry application and configuration. 1, the main instrument air system air thermal power stations, factories miscellaneous compressed air systems, compressed air systems and water treatment systems with compressed ash four different occasions Cottle compressor, the following were introduced : run thermal power generating units requires a lot of control instruments to support operations. These actions are controlled by compressed air pressure meter controlled. Control instrumentation systems for compressed air, air pressure is usually hired 0.65-0.70mpa. The size of the gas consumption of the compressor can be determined according to the size of the fire cattle Which brand of power unit capacity, usually for two 300MW thermal power units multiplied by the instrument with compressed amount of 40m3 / min. Taking into account the thermal power of compressed air during operation requirements sometimes big, sometimes small, usually use two 20m3 / min air screw compressors. When the gas consumption of less than 20m3 / min screw compressor will automatically stop, in order to save energy, but because of the special requirements of power plant instrument air, that at any time can not stop the supply of compressed air, so the configuration requirements for both air compressors Open a preparation of a repair, so air compressor, air compressor Instrument number is four 20m3 / min, and screw air compressors of course many thermal power plants are not exactly the same configuration. After the compressor is selected, it is necessary to consider air quality problems, because the compressed air is supplied to the instrument used, the quality of compressed air also have higher requirements, in accordance with ISO / DP8573 / 1-88 grade quality standards, instrumentation Compressed air grade requirements normally solid particles 2, a water content of 3, an oil content of 2. Air compressor with a long, oil, coke head there will inevitably be a phenomenon. That carbon is how did this happen? And how to clean? The four main factors that affect coke formation: an air filter with dust particles in the air intake of the oil to thicken, increasing the time of oil oxidation reaction, thus accelerating the rate of coke formation. Therefore, care must be taken properly installed air filter, clean-up was found damaged and must be replaced. Second, the temperature of different grades and types of lubricants, the starting temperature oxidation are not the same. Compressor long run in the high temperature region will accelerate the oxidation of lubricating oil. Third, the quality of air compressor lubricants lubricants generally do not occur in the specified period of use coke phenomenon, but there is more oil in the original procurement channels, but also changing the different lubricants brand, its quality will inevitably be Which is a fair price difference between the air compressor, coke phenomenon is not uncommon in these situations. After four, extended use of lubricants lubricants exceed the prescribed period of use, according to the appearance of the situation may be extended lubricant life, even without a timeout should be shortened with increasing temperature the oil cycle. In this case the air compressor in a very short period of time due to carbon and can not run. The oil, coke head maintenance cleaning methods. Circuit, the host carbon less severe, you can use the online cleaning agent (compressor online carbon cleaner or cleaning oil), has been killed by a host or coke serious immersion cleaning pipes placed directly into the container; large host can be closed after the export pipeline, oil pipeline into the cleaning agent soak. When soaked in detergent requirements described prevail, generally 8-12 hours, and some corrosive cleaning agents should strictly abide by its requirements soaking time air compressor production Which is good, Qin Wei Air (certified), air compressor Limited by Wei Qin Xianyang compressor. Xianyang Qin Wei Compressor Co. (www.xykyj.cn/) is Xianyang, compression, separation equipment leader, over the years, the company implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Qin Wei Air leadership with the staff warmly welcome all inquiries negotiations to create Qin Wei Air a better future.
