The air compressor market in China is mainly composed of piston type, screw type, centrifugal type, sliding vane type and other air compressors, among which the piston type accounts for the largest proportion, followed by screw type, centrifugal type, sliding vane type, scroll type and so on.In recent years, with the development of screw air compressor and centrifugal air compressor, the proportion of piston air compressor in the industry has decreased, but it still dominates the market.
Screw type air compressor
Compared with piston type air compressor, screw type air compressor with low operating cost, from the perspective of the whole life cycle of the machine, screw machine investment recovery rate than the piston machine 20%, energy-saving effect is obvious and other advantages, therefore, screw type air compressor in many areas began to gradually replace the piston type air compressor.
Especially in the "low carbon environmental protection", under the development trend of energy saving of domestic mining, metallurgy, electric power, electronics, machinery manufacturing, medicine, food, textile and light industry and the rapid development of petrochemical industry, will also accelerate the backward technology, production equipment, promote compressor equipment from low value-added upgrade to high added value, and thus further for screw compressor industry development opportunities.
"The eleventh five-year plan" period, our country screw machine to the piston machine realized the partial substitution, anticipates the screw machine to the piston machine substitution will continue to carry on, the piston machine demand will decline gradually, but in view of the piston type air compressor more extensive application domain and the relatively low price, its market demand still will maintain certain level.Qianzhan industry research institute predicts that the market size of screw air compressor in China will maintain an annual growth rate of 15% from 2014 to 2018.
Piston type air compressor
In recent years, although the proportion of piston air compressor in air compressor has decreased, it still occupies the main position.In 2008, the proportion of piston air compressor in the air compressor accounted for 81.8%, although the proportion has declined in the past two years, but the overall remains above 75%.In 2011, the market size of piston air compressor in China was about 100.137 billion yuan, and in 2012, the market size of piston air compressor was about 108.039 billion yuan.
Forward-looking industry research institute "in 2014-2018 in China's air compressor industry transformation and upgrading of production and marketing demand forecasting and analysis report, the data shows, the west developed countries screw air compressor market share is about 80%, Japan screw compressor in 1976 accounted for 27%, rising to 85% in 1985, the future of our country's strength of piston compressor have been replaced will continue to increase, but considering the equipment replacement costs, the replacement process still needs a period of time.
Centrifugal air compressor
As the centrifugal compressor is oil-free compressor, it has good safety and sanitary performance, and can be used in food, pharmaceutical, mining, air separation and other industries with higher environmental requirements.At present, centrifugal air compressor is mainly used in steel, petroleum chemistry, shipbuilding, electric power and automobile, and its demand can account for more than 70% of the total demand of centrifugal air compressor.At present, steel, shipbuilding, electric power, automotive industries in the downturn trend, is expected to downstream growth slowdown, will make centrifugal compressor industry growth slow down.
Scroll compressor
Vortex type air compressor is developed in recent years, the latest model of air compressor, compared with the traditional air compressor, it has the advantages of novel structure, small volume, light weight, low noise, long life, stable gas continuous and easy operation, less maintenance and a series of excellent technical performance, was the industry known as "without air compressor maintenance" and "the new revolution of air compressor", is an ideal model below 50 HP air compressor.At present, scroll compressor is still mainly used in the field of refrigeration.
In recent two years, affected by the economic downturn, the decline in sales of air conditioners led to a decline in sales of turbine air compressors. However, with the improvement of the economic situation and the improvement of consumer confidence index in the future, turbine air compressors can still maintain a certain market growth rate.
