The overall development status of China's screw air compressor
China's air compressor market is mainly composed of screw, piston, centrifugal, sliding vane and other air compressors, of which piston type accounts for the largest, followed by screw type, centrifugal type, slide type and so on. Due to global energy shortages, the prices of energy and raw materials continue to rise, coupled with the rising cost of local labor, which has led to an increase in operating costs for manufacturing companies and a shrinking profit margin, which has led to a reduction in demand for compressors.
In order to reduce the extent of profit decline, manufacturing companies will accelerate the improvement of production automation, reduce manpower input and extend equipment life in the future. Under this trend, oil-free screw air compressors with high automation, energy saving, environmental protection and high cost performance will be widely used in the market in the future. Below Dongguan Hua Hong briefly commented on the development status of screw air compressors.
According to different lubrication methods, screw air compressors can be divided into three types: oil lubrication, oil-free water lubrication, and oil-free dry screw air compressor. According to relevant research and research, in 2008, the demand for screw air compressors in China was about 70,000 units, and the market scale was about 9 billion yuan. Among them, oil-lubricated screw air compressors accounted for the vast majority of market share. Water-lubricated screw air compressors At present, the market size has not yet been formed, and the market share of dry screw air compressors is small, but from the development in recent years, the growth rate is much higher than the average growth rate of screw air compressors.
At present, there are about 150 manufacturing companies producing screw air compressors in China, but the main market is occupied by foreign and Taiwan-funded enterprises. According to relevant data, the market size of dry screw air compressors in 2008 was close to 1 billion yuan, mainly occupied by two brands, AC and IR, and two brands of IR and AC entered the Chinese market for many years in the dry screw air compressor industry. In the past, the brand layout of dry screw air compressors has been relatively stable, and no other brands have attempted to enter the domestic market on a large scale.
The five major industries of steel, textile, automotive, petrochemical, and shipbuilding are the main application industries for small dry screw air compressors. The demand for these five industries can account for 70% of the total demand for small dry screw air compressors. At the same time, these five industries are also the industries most affected by the world. As the impact of the financial crisis continues to deteriorate, the demand for small dry screw air compressors in 2009-2010 is expected to be the same as in 2008. As the financial crisis gradually declines, There will be a recovery in market demand, and annual demand is expected to increase year by year with an average growth rate of 15% after 2010.
In summary, the screw air compressor has a certain development market in China.
