Air Compressor Tank You Should Know

The air compressor air tank or receiver is an important part of the compressed air system. It is mainly used to store compressed air for use during peak demand periods.

Working principle of air compressor tank
The air tank stores compressed air to balance the contradiction between the continuous exhaust of the air compressor and the intermittent demand of the gas-using equipment, eliminating air pressure pulsation. When the gas consumption increases, the gas in the tank can be replenished instantly; when the gas consumption decreases, the excess gas is stored in the tank to avoid frequent start and stop of the air compressor, resulting in waste of resources.


Understanding of compressor air tank parameters
1. Pressure level
Working pressure ≥ maximum exhaust pressure of the air compressor, working pressure > 10Bar belongs to high pressure type, working pressure < 8bar belongs to low pressure type, and 8bar~10bar belongs to medium pressure type.

2. Material
1. Carbon steel: economical and durable, suitable for general industry
2. Low alloy steel: high strength and pressure resistance, used in special working conditions

The role of air compressor tank
1. Provide a constant pressure compressed air flow. Uniform airflow makes pneumatic tools easier to use and reduces the pressure on the compressor.

2. Temporary storage of compressed air. Storing compressed air allows the system to evenly distribute the peak of compressed air demand within a shift.

3. When the compressor is not running, the compressed air in the air tank is still available. Reduce the sudden demand for air compressors and extend the service life of air compressor equipment.

Notes on air compressor installation
1. It needs to be installed vertically and the foundation load-bearing capacity is ≥1.5 times the weight of the tank
2. Keep 3-5 meters from the air compressor, and a check valve needs to be installed in the middle
3. The inlet and outlet adopt a "low in and high out" layout to enhance water removal


Solutions to common problems of compressor air tanks
1. Large pressure fluctuations
Check whether the air tank volume is too small

2. Condensate accumulation
Check whether the efficiency of the precooler has decreased

3. The safety valve is frequently activated
Check whether the gas-using equipment is overloaded
