Two Stage Piston Air Compressor

two stage piston air compressor

two stage piston air compressor definition
The two-stage piston air compressor uses graded compression technology to complete the initial compression through the low-pressure cylinder, and then transports the gas to the high-pressure cylinder for secondary compression. The two-stage piston air compressor can reduce the single-stage workload and improve efficiency.

Two stage piston air compressor working principle
1. Primary compression
The gas is first compressed in the low-pressure cylinder, sucked in through the intake valve and pushed to push the piston to complete the initial compression.

2. Cooling
The gas temperature is reduced through an external cooler to reduce the power consumption of the secondary compression

3. Secondary compression
The compressed gas after cooling enters the high-pressure cylinder for deeper compression, and is discharged from the cylinder after reaching a higher pressure.


Advantages of two-stage piston air compressor compared with single-stage piston air compressor

1. Low energy consumption
Two-stage compression reduces exhaust temperature through intercooling, reduces the risk of lubricating oil carbonization, and is close to isothermal compression theory, saving about 34% energy compared with single-stage compression.

2. Long service life
The pressure difference per stage is reduced, the piston force is reduced by 42%, reducing mechanical wear and increasing the service life of the piston air compressor.

3. Low maintenance cost
The structural complexity is higher than that of the single-stage model, but the operation is more stable, and the comprehensive maintenance cost is lower than that of a single-stage piston air compressor.

Application of two-stage piston air compressor
1. Manufacturing industry
Mostly used to provide power source for pneumatic tools of factory machinery and equipment, such as spray guns, grinders, etc.

2. Construction
Generally used for construction equipment such as concrete spraying, drilling, vibrators, and also for site cleaning and dust removal.

3. Medical industry
Provide stable supply of oxygen, nitrogen, etc. for medical departments, and provide power for medical equipment such as ventilators and operating rooms.


4. Food and beverage industry
Filling, packaging and other production processes, as well as gas separation and sanitation cleaning.
