Gas storage tanks can be divided into many types according to different pressures, including low pressure, medium pressure, high pressure, negative pressure and so on. There is no direct connection between the gas volume and air pressure of the gas storage tank, but the two complement each other.
　　 The capacity of the air storage tank is mainly based on two basis: First, it is determined according to the air output of the air compressor. Because if the gas storage tank is directly connected to the back of the air compressor, its role is to play a buffer role. At this time, the size of the air storage tank can be calculated according to the exhaust volume of the air compressor. Generally, the volume of the air storage tank is equal to one-third to one-fifth of the exhaust volume of the air compressor. The second is to determine the capacity of the gas storage tank according to the gas consumption of the gas equipment. The larger the gas tank, the longer it can be maintained. This is mainly to consider that when the air compressor fails or is repaired, the gas volume of the gas storage tank must be maintained to continue normal operation of the gas equipment to ensure normal operation of production. Determine the capacity of the gas storage tank according to the gas consumption per unit time and the time to be maintained.
　　 The pressure of the air storage tank is OK as long as it is equal to or greater than the pressure of the air compressor. For example, an air compressor with a pressure of 8 kg should be equipped with an 8 kg air tank. Or 10KG is fine, but it can't be too much, otherwise it will cause unnecessary waste. It can also cause damage to the air compressor.
