First, the metallurgical industry: iron and steel metallurgy industry sub-sector and non-ferrous metal smelting and production industry a steel industry: air compressor power is mainly performed by the gas meter, 2 meter sweep, nonferrous metal smelting and manufacturing: air compressor is mainly execution for power, gas meter, spraying two power industry main purposes: instrument with compressed air system, ash handling system with compressed air, compressed air plant hybrid systems, compressed air treatment systems, water treatment to include in boiler feed water treatment and industrial wastewater treatment systems, hydropower station will have the power to use compressed air system equipment. Third, a light industry, food and beverage: no contact points, indirect contact and direct contact with the gas. Not in contact: the main power actuator, such as control cylinders, etc indirect contact: mainly provided by oil-free reciprocating compressor gas source, such as cans, bottles of cleaning direct contact: as raw material mixing, fermentation, oil content of the request is high, cutting the need for compressed air sterilization deodorant treatment 2, the pharmaceutical industry: Do not contact the main driving force execution and instrument air, direct contact with the gas consumption due to large and stable gas, colleagues require high air quality, the general election centrifugal type, if the volume is not large, the choice of oil-free screw. 3, the cigarette industry: Compressed air is a major addition to the electric power source, usually used in the injection wire machine equipment, cigarette volumes, access and packaging equipment, and also with the execution and instrumentation, power, equipment cleaning. 4, rubber and plastic products: mainly used for dynamic execution, gas meter, plastic is also used for blow molding processes. Fourth, the chemical fiber industry main purposes: the cotton industry as the main power source to use clean compressed air, for oil content is relatively high; chemical fiber industry is mainly gas meter and gas suction gun silk dyeing mainly power and instrument air. Fifth, the water plant is mainly used for dynamic execution. 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, the following were introduced: run thermal power units requires a lot of control instruments to support operations. These actions are controlled by compressed air pressure meter controlled. For systems with compressed air control instrumentation Cottle air compressor, air pressure is usually hired 0.65-0.70mpa. The size of the gas consumption can be determined according to the size of the fire 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 Qin Wei compressor, according to ISO / DP8573 / 1-88 quality rating Which standard air compressor brand cattle, instrument grade compressed air requirement is generally solid particles 2, a water content of 3, an oil content of 2.
