Compressed Air Receiver Tank

Gas storage tank refers to the equipment specially used to store gas, and plays the role of stabilizing system pressure, according to the pressure of the gas storage tank can be divided into high-pressure gas storage tank, low-pressure gas storage tank, atmospheric pressure gas storage tank. According to the different materials of the gas storage tank can be divided into: carbon steel gas storage tank, low alloy steel gas storage tank, stainless steel gas storage tank. The air compressor's air receiver tank consists of end caps, a cylinder body, and several attached connections. The end caps and cylinder body are formed by bending plates. The tank includes a cylinder body, and the tank body is connected to the upper and lower end caps through flanges. The outer sides of the upper ellipsoidal end cap are equipped with interfaces for pressure gauges, air outlets, and safety valves that communicate with the tank's interior. The cylinder body contains an air storage chamber, and the bottom of the lower end cap is equipped with a drain valve. Support brackets are situated on the outer wall of the lower end cap. Inside the air storage chamber, a dewatering device is installed. 

The Significance of Compressed Air Receiver Tanks for Air Compressors

1. It is used for air storage buffering to prevent frequent loading and unloading of the air compressor and to eliminate the majority of liquid water.


2. As the demand for compressed air at the end of the compressed air system is typically not constantly stable, the use of an air receiver tank is essential to balance system pressure stability and reduce the frequent loading and unloading of the air compressor.

3. It further cools the compressed air that has been dried to reduce the moisture content in the compressed air.

Selection of Compressed Air Receiver Tank Capacity

1. When selecting an air receiver tank, the pressure should be chosen to be greater than or equal to the discharge pressure of the wholesale screw air compressor. For instance, if the pressure is 8 kilograms, the selected air receiver tank pressure should not be less than 8 kilograms.

2. The chosen air receiver tank volume typically falls within the range of 0.3 to 0.5 times the compressor's discharge capacity. If environmental conditions permit, selecting a larger capacity air receiver tank is beneficial for storing more compressed air and improving pre-water removal efficiency.

3. In most industries, carbon steel and low-alloy steel air receiver tanks are commonly selected (low-alloy steel tanks have higher yield strength and toughness than carbon steel tanks, although they are relatively more expensive). Stainless steel air receiver tanks are mainly used in industries that demand high overall performance, such as the food industry, medical pharmaceuticals, chemical industry, and microelectronics, due to their corrosion resistance and formability requirements.

The Role of Compressed Air Receiver Tanks

An air receiver tank serves the purpose of temporarily storing compressed air and aiding in the more efficient operation of the compressed air system. It has three primary functions within the compressed air system: storing compressed air for brief periods of high demand, providing a stable air signal to the compressor control device, and acting as an auxiliary heat exchanger to enhance the efficiency of air dryers when used as a "wet tank".
