How to choose the most suitable pressure vessel gas Storage Tank?

The main role of air Storage Tanks in air compression systems is to ensure a stable air supply. Compressed air in the tank to precipitate water, adjust the pneumatic equipment due to unbalanced air volume and air pressure fluctuations, increase the pressure stability of air equipment, or reserve part of the compressed air, in the event of a compressor failure, so that the user with this part of the compressed air for pneumatic equipment or pneumatic control system for emergency purposes, therefore, the selection of a suitable pressure vessel storage tank, is to protect the entire air system The key link. How to choose the most suitable pressure vessel storage tank? We offer some guidance from 3 aspects: pressure, volume and material.

Pressure selection

Depending on the pressure of the tank, it can be divided into high pressure tanks, low pressure tanks and atmospheric tanks. Selection of gas storage tank pressure as long as it is greater than or equal to the exhaust pressure of the air compressor, that is, the pressure is 8 kg, the choice of gas storage tank pressure is not less than 8 kg.

Volume selection

The volume size of the optional storage tank is approximately in the range of 0.3-0.5 of the exhaust volume of the air compressor; if the environmental conditions allow, you can choose a large volume storage tank, which helps to store more compressed air and better pre-distribution of water. Example: If the air compressor exhaust volume is 1 cubic metre per minute and the pressure is 8 kg. According to the formula for selecting a storage tank, the volume of the tank = the exhaust volume of the compressor * 0.3 or the exhaust volume of the compressor * 0.5 range, (not less than one-third or one-fifth of the exhaust volume), the recommended volume of 0.3 cubic meters or 0.2 cubic meters of storage tank; if the subsequent still need to increase the amount of air, the volume of the tank can also be appropriate to enlarge the space, such as the choice of 0.5 cubic meters, or 0.6 cubic metres, or 1 cubic metre, etc.

Material selection

Depending on the material chosen, gas storage tanks can be divided into carbon steel tanks, low-alloy steel tanks and stainless steel tanks, which are used in conjunction with air compressors, cold dryers, filters and other equipment to form compressed air stations as a power source for industrial production. Most industries choose carbon steel tanks and low-alloy steel tanks (low-alloy steel tanks have higher yield strength and toughness than carbon steel tanks and are relatively more expensive); stainless steel tanks are mainly used in the food industry, medical and pharmaceutical, chemical industry, microelectronics and other equipment and machine industries that require high overall performance (corrosion resistance and formability). Users can choose according to the actual situation.
