An air compressor is a device used to compress gas. Air compressors are similar in construction to water pumps. Most air compressors are reciprocating piston type, rotating blades or rotating screws. Centrifugal compressors are very large applications.
The basic information
· Chinese name: Air compressor
· Foreign name: Air Compressor
· Energy consumption type: electricity
· Principle: Compressed air
Air compressor (English: Air compressor) is the main body of the air source device. It is the device that converts the mechanical energy of the prime mover (usually the motor) into gas pressure energy. It is the pressure generator of compressed air.
Development of air compressor
Forward-looking Industry Research Institute released "China air compressor industry production and sales demand forecast and transformation and upgrading analysis report" data show that the market size of China's air compressor industry is more than 8% growth, 2010-2011 growth rate even exceeded 28%, the rapid expansion of the market size. However, in such a large market, foreign companies have long controlled most of the market. According to the prospectionnet data show that in 2009, China's air compressor industry has nearly 400 production enterprises, of which the number of domestic enterprises is nearly 90%, the total sales revenue of about 6 billion yuan, accounting for 40% of the whole industry; The number of foreign-funded enterprises is close to 10%, and the total sales revenue is about 9 billion yuan, accounting for 60% of the whole industry.
However, domestic enterprises continue to strengthen technological innovation. The leading domestic enterprises in the industry, such as Kaishan Stock, continue to make progress in technology, the company's product performance has reached the international level, and has made gains in the high-end market dominated by foreign investment. With the continuous improvement of product performance and technological upgrading, the market share of domestic enterprises is also increasing year by year. Taking screw air compressor as an example, from 2009 to 2011, screw air compressor sales increased by 14,800 units by 32,800, the compound annual growth rate was 48.87%, the market share increased from 14.10% in 2009 to 19.40%; The sales volume increased from 0.08 million units to 20,100 units, and the market share increased from 0.80% to 11.90%. The development is very rapid.
