The air compressor tank is a pressure vessel specially used to store compressed air. The main function of the air tank in the air compression system is:

1. Let the compressed air buffer, make the air supply more stable, reduce the frequent start-up of the air compressor, and let the compressed air settle in the air storage tank is more conducive to water removal and pollution removal. It is mainly used with air compressors, refrigeration dryers, filters and other equipment, and also plays a very important role in the compressed air of the air compressor.

The air storage tank at the outlet of the air compressor plays the role of stabilizing the air outlet pressure and buffering. Since the air consumption at the end of the compressed air system is generally not stable at all times, the air storage tank should be used to balance the stability and reduction of the system pressure. Frequent loading and unloading of air compressors.

2. Prevent the compressed air pipeline from returning liquid for some reason during the shutdown period of the air compressor, and backflow into the air compressor due to its damage.

3. Cool the dried compressed air again to reduce the moisture content in the compressed air. At the same time, letting the compressed air settle in the air storage tank is more conducive to water and pollution removal.

The basic requirements for gas storage tank selection are as follows:

1. The volume of the air storage tank should be between 10% and 20% of the compressor displacement. We generally choose 15%. When the air volume is large, the volume of the air storage tank should be appropriately increased. When the on-site gas consumption is small, it can be less than 15%, preferably not less than 10%.

2. The processing capacity of the dryer and filter should be consistent with the compressor's discharge capacity.

3. The filter before the dryer should be equipped with an automatic drain.

4. When using an adsorption dryer, the compressor should reserve corresponding air consumption.

5. After the dryer is installed in the gas storage tank, the function of the gas storage tank is fully reflected, playing the role of buffering, cooling and sewage, which can reduce the load of the dryer, and is used for the working condition of the system with more uniform air supply. The dryer is installed before the gas storage tank, the system can provide a large peak adjustment capacity, and is mostly used in working conditions with large fluctuations in gas consumption.

Therefore, it is very necessary for the air compressor to install the air storage tank. Only when the air storage tank and the supporting equipment of the air compressor are used reasonably, can the mechanical equipment exert greater efficiency.
