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, it can be divided into high-pressure gas storage tank, low-pressure gas storage tank and atmospheric pressure storage 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, it can be divided into high-pressure gas storage tank, low-pressure gas storage tank and atmospheric pressure 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. Gas storage tank (pressure vessel) is generally composed of cylinder body, head, flange, pipe, sealing element and bearing parts and components. In addition, it is also equipped with a safety device, a meter and internal parts to complete the functions of different production processes.

Air compressor is one of the important large fixed power equipment in coal mine. It is widely used underground and on the ground. The air storage tank is the supporting equipment of the air compressor. It is installed outdoors. The air enters the compressor and is pressurized and then sent to the gas storage tank. Compressed air sedimentation in the reservoir water, adjust the pneumatic equipment pressure fluctuation caused by unbalanced gas, increase the gas pressure stability of the equipment, or reserve part of compressed air, the air compressor failure occurs, the user use this part of the compressed air to the pneumatic device or pneumatic control system for use in emergency treatment.
