The gas storage tank refers to the equipment specially used for storing gas. At the same time, it plays the role of stabilizing the pressure of the system. 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 gas storage tank. According to the material of the gas storage tank, it can be divided into: carbon steel gas storage tank, low alloy steel gas storage tank and stainless steel gas storage tank. The gas storage tank (pressure vessel) generally consists of parts and components such as a cylinder, a head, a flange, a nozzle, a sealing member, and a support. In addition, it is equipped with safety devices, gauges and internals that perform different production processes.
The air compressor is one of the important large-scale fixed power equipment in the coal mine. It is widely used in underground and on the ground, mainly for the wind, wind drill and rock drill that supply the mining face. The gas storage tank is an auxiliary equipment for the air compressor. It is installed outdoors. The air enters the compressor and is sent to the gas storage tank after being pressurized. Then, the gas storage tank is supplied to each gas location. The gas storage tank is in the air compression system. The main role is to ensure the stability of the gas supply. The compressed air deposits water in the gas storage tank, adjusts the pneumatic equipment to cause air pressure fluctuation due to unbalanced gas consumption and increases the pressure stability of the gas equipment, or reserves a part of compressed air, so that the user can use the air compressor when the air compressor fails. This part of the compressed air is used for emergency treatment of pneumatic equipment or pneumatic control systems.
