Oil free air compressor factory air compressor is the abbreviation of the air compressor, is the basic product of industrial modernization, often said in the electrical and automation has the meaning of all pneumatic; And air compressor is to provide air source power, is the core of the pneumatic system equipment mechanical and electrical air source device in the main, it is the original motion (usually motor) mechanical energy into the gas pressure energy device, is the compressed air pressure generating device.

The market size of China's air compressor industry has increased by more than 8%, and even exceeded 28% from 2010 to 2011. The market size is expanding rapidly. However, in such a large market, most of the market was controlled by foreign companies for a long time. 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 is about 6 billion yuan, accounting for 40% of the 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.

Structural characteristics of air compressor:

The compressor is directly driven by the motor, so that the crankshaft produces rotary motion, driving the connecting rod makes the piston reciprocate motion, causing the change of cylinder volume. Due to the change of pressure in the cylinder, through the inlet valve to make the air through the air filter (silencer) into the cylinder, in the compression stroke, due to the cylinder volume reduction, the role of compressed air through the exhaust valve, the exhaust pipe, one-way valve (check valve) to storage tanks, when the exhaust pressure to achieve the rated pressure of 0.7 MPa is controlled by a pressure switch and automatic stop. When the pressure of the gas storage tank drops to 0.5-0.6mpa, the pressure switch will automatically start the connection.
