The top ten centrifugal air compressor brands are:
1, Atlas Copco (referred to as AC)
The multinational conglomerate, headquartered in Sweden, air compressor manufacturers are just one of its subordinate groups. Due to years of continuous acquisition, AC can produce almost all forms of air compressors, quite famous. The strength of the largest and most extensive products, the first screw machine manufacturer. Oil-free and centrifugal machines are unrivaled and have a large market share.
2, Ingersoll Rand (referred to as IR)
The earliest joint venture in China to produce screw machine company, founded in Shanghai in 1987. Started as a construction machinery and refrigeration machine, the market share is second only to Atlas. IR's most profitable product in China is centrifugal air compressor. Another profitable product is the mobile air compressor, which is widely used in China.
3, the United States Shouli (Sullair)
The United States, a large aerospace (military) companies affiliated with the company, the machine is certainly good. The main products are oil screw and mobile, its mobile in recent years, the main localization, will increase its market share. Shouli company mainly through the agent sales, recently the number of its agents has increased greatly, in the textile, automotive and other industries have considerable performance. The main advantage is reflected in the factories have been set up in China, the price of its high-horsepower type products is cheaper. The product runs reliably and has a long life.
4, Kaiser
Germany's largest air compressor manufacturer, strong production capacity, enjoy a good reputation in Europe. There is no factory in China. It has set up a branch in Shanghai, China, and an agent in Shenzhen, and has not yet established a sales network in the country. Advantage is very famous in Europe and its price is competitive. The disadvantage is that it does not produce oil-free type, the network is not sound, and the sense of innovation is not strong.
5, Compair / Demag (referred to as Compair)
British company, mainly in the production of sliding vane air compressors (≤ 50HP) and known in the industry. In recent years, Compair has become a global air compressor company by acquiring the screw compressor division of Demag in Germany and Leroi in the U.S. In 1993, it set up a factory in Shanghai, but its nationwide sales network in China has not yet been established, so it does not have a great influence.
6, the United States Quincy
From 1920 has been committed to the compressed air technology industry, specializing in the manufacture and sale of the highest quality air compressors and vacuum pumps. The products are widely used in global manufacturing, medical and climate control systems, and any industry that requires the use of a safe and reliable air source. The rotor of the main engine is independently and carefully designed and manufactured by Quincy, using an oversized diameter rotor for high mechanical reliability and durability.
7, Japan's Shinko
Started at the beginning of the last century, so far there has been nearly a century of long history. 1915 production of Japan's first high-pressure reciprocating compressor, 1956 and successfully introduced to the market Japan's first oil-free screw air compressor. 1966 began to get involved in the production of centrifugal compressors, so far as the world has become one of the few can independently produce the piston type, Since then, we have become one of the few compressor manufacturers in the world that can independently manufacture piston, screw, centrifugal process compressors and air compressors.
8, Fusheng
Joint venture, China's domestic three factories: Zhongshan, Shanghai, Beijing, in China has been a highly recognized air compressor manufacturers. Through its good quality small piston machine to open up the Chinese market, dealers throughout the country, but its screw machine is still a representative of the low-grade machine. The biggest advantage is cheap price and high visibility. The disadvantage is the poor quality and high failure rate of large horsepower type machine.
9, Liu two air
By Liuzhou second air compressor factory restructured into a joint-stock company, is China's gas compressor, air drying and purification equipment and plastic molding machinery production key backbone enterprises. 1996 through the ISO9001 quality system who. The products have been awarded the national quality silver medal and the title of Ministry of High Quality Products for many times. Now has 6 categories, 16 series, 119 varieties of specifications of products.
10, Shanghai Oriental
Founded in 1921, has nearly 90 years of experience in manufacturing compressors and a number of high-quality management personnel and experienced compressor technology experts. In good faith, strength and product quality recognized by the industry, and has passed the ISO9001 international quality system certification, business outlets throughout the country.
Expanded Information:
Centrifugal air compressor mainly consists of two main parts: rotor and stator. The rotor includes the impeller and the shaft. The impeller has blades, in addition to a balance disk and a part of the shaft seal. The main body of the stator is the casing (cylinder), and the stator is also arranged with diffusers, bends, refluxers, bursting pipes, exhaust pipes and part of the shaft seal. The centrifugal compressor works on the principle that when the impeller rotates at high speed, the gas rotates along with it, and under the action of centrifugal force, the gas is thrown into the diffuser at the back, and a vacuum is formed at the impeller, and then the fresh gas from the outside enters into the impeller. The impeller keeps rotating, and the gas is continuously sucked in and thrown out, thus maintaining a continuous flow of gas.
