Why Air Compressor To Be Equipped With Gas Tank Cylinders
- Oct 11, 2017 -


The installation of the Gas Tank is of paramount importance to the air compressor.
On the one hand, the air compressor outlet tank can not only play a stable outlet pressure, cushioning and other effects, at the same time, there is an important role in the general user should not notice that is to prevent air compressor downtime, compressed air Pipeline for some reason to return the liquid, pour into the air compressor, because of its damage. If you remove the Gas Tank, in the pipeline design, to use inverted U-bend design to play the same role.
On the other hand, it is to maintain the compressed air system pipe network pressure do not appear big fluctuations. Since the gas at the end of the compressed air system is generally impossible to be stable at all times, it is necessary to use a Gas Tank to balance the smoothness of the system pressure and to reduce the frequent loading and unloading of the air compressor. Second, the other effect of the Gas Tank is to cool the dry compressed air again to reduce the moisture content in the compressed air.
The main load of the Gas Tank is the internal gas pressure, the wind load and the seismic action. Wind pressure should be considered in wind load. The wind load factor of high pressure spherical tank is generally 0.30 ~ 0.35. The horizontal seismic action of the wet tank includes the seismic force generated by the tank and the weight of each tower, and the hydrodynamic pressure caused by the vibration of the water in the Gas Tank. The horizontal seismic action of the dry tank includes the seismic force generated by the weight of the cylinder and the weight of the piston. Calculate the snow load to consider the eccentric moment of snow caused by the local accumulation of snow in the top of the tank.
Under the action of various loads and internal pressure, the shell wall and the roof of the tank are analyzed by the forceless theory of the shell structure. The thickness of the wall and the roof of the low pressure tank is generally not determined by the strength, but by the structural and corrosion requirements. The guide column of the column-type gas storage tank is subjected to the wind force and the horizontal seismic force on the tower section transmitted by the guide wheel. The guide wheel pressure can be decomposed into various planes according to the plane truss analysis method. The inner column, the upper and lower girders and the guide rails of the spiral rails contain the space frame, and bear the horizontal load of the wind load and the seismic force from the guide wheel. The cylinder of the dry Gas Tank shall check its local and overall stability under the action of wind load, horizontal seismic force and internal pressure. The spherical tank has a strong tensile strength under internal pressure, but its stability is poor under negative pressure. Therefore, it is necessary to specify the minimum working pressure to ensure that no negative pressure occurs when the temperature drops and the internal pressure decreases.
In the production of low-pressure Gas Tank, the tank is divided into several parts in the processing plant prefabricated, and then the total installation site, which can reduce the site to install the weld. From the parts lofting, production, to the overall installation of all stages should be strictly checked to ensure the final overall accuracy. When installing the tank in the dry Gas Tank, first lay the bottom plate, assemble the piston on the floor, and support the top truss above the piston. At the same time, the lower part of the tank and the column. And then to the piston below the blast to rise, the use of the piston as a construction platform to install the upper sections of the wall. Step up the piston, step by step to install the column and the wall, to be designed after the height of the top truss and the top of the column fixed, and then put down the piston, all installed to complete. Larger volume of high-pressure Gas Tank cylinders can be pre-pressed block shell, welded in the field. After welding, all welds are required for quality inspection.
