1. Store air to meet the demand of sudden and instantaneous increase in gas consumption of gas consuming equipment;

2. Store air and eliminate the pulsation of air flow in the pipeline;

3. The air is initially cooled and a part of the liquid water is separated out. Therefore, the air storage tank shall be drained regularly;

4. It can ensure the automatic shutdown of the air compressor. The air compressor will stop automatically as soon as the air storage tank is filled with air under the set pressure, so as not to waste electric energy by running the air compressor all the time.

Theoretically, the larger the air storage tank, the better, which can reduce the number of frequent starts of the air compressor. Star delta startup belongs to power frequency startup, and the instantaneous current of motor startup is about 7 times of the rated current. Frequent startup will cause great damage to the electrical part of the air compressor, which will reduce the service life of the electrical part, and have great impact on the power grid, affecting the normal use of other electrical equipment.
