Gas storage tanks are an essential equipment in today's industrial production process. With its irreplaceable advantages, gas storage tanks play a role in the industry. The following is a brief introduction to the application of gas storage tanks in the gas path. The gas storage tank is a device for storing and transporting gas. The gas tank is mainly made of stainless steel, alloy stainless steel and carbon steel. According to the pressure characteristics of the tank, the gas storage tank is generally divided into a normal pressure gas storage tank, a low pressure gas storage tank and a high pressure gas storage tank. The air tank equipped with the air compressor can store and store compressed air, reduce the pressure pulsation caused by the discontinuous compressor exhaust, ensure the air supply and gas supply are stable, and can cool the compressed air to avoid overloading the filter and desiccant. . The housing material is the primary consideration when selecting a gas storage tank. In general, a gas storage tank is a pressure vessel. There are three main types of housing materials: 16MnR, 16MnDR and Q235-B. Table 1 shows the usage status and temperature range of various materials specified in GB150 Steel Pressure Vessels. Table 1 Material Name Steel Plate Usage Temperature Use State Standard Hot Rolling Hot Rolling Normalizing Normalizing 3 Gas Storage Tank Function In gas pipeline application, the role of the gas storage tank is to buffer, cool down, remove water and store energy. As a rear configuration of the air compressor, the gas storage tank can weaken the pulsation of the airflow discharged from the piston air compressor, ensuring continuous output airflow and stable pressure. By adiabatic expansion and natural cooling, the gas is cooled, and impurities (such as dust, oil, moisture, etc.) in the compressed air are further separated to ensure continuous supply of sufficient gas. The compressed air output from the air compressor contains a large amount of pollutants such as moisture, oil and dust. The metamorphic oil forms a tar-like substance, which leads to the rubber and plastics division. The research direction is the development of liquid crystal glass substrate equipment. Material material deterioration and aging; moisture has a great influence on pneumatic components, which will cause the pipeline metal to rust, water to form ice, to deteriorate the lubricant and rinse off the grease; rust and dust will wear the relative moving parts, accelerate the seal Damage, resulting in air leakage; liquid oil and dust discharged from the exhaust port, will pollute the environment and affect product quality. Therefore, it is necessary to employ a multi-stage separation filter device in a compressed air system or to pre-process compressed air into a dry gas having a constant relative humidity. After the air compressor gas comes out, it enters the gas storage tank and passes through the filter to the dryer. When the compressed air of the air compressor passes through the gas storage tank, the airflow hits the tank wall at high speed to cause convergence. The temperature inside the tank drops sharply, the water vapor liquefies, the water and oil are removed a lot, and the running load of the dryer is greatly reduced. When compressed air passes through the gas storage tank, a part of the air is stored in the gas storage tank. The output pressure of the gas storage tank is relatively stable, the airflow passing through the filter is stable, and the filter can be greatly improved, which helps to extend the service life of the filter. . The gas tank behind the precision filter not only buffers, but also has energy storage effect. After the filter is clogged, it helps to maintain the air pressure and the air entering the workshop is stable and stable. The gas storage tank must be selected with gas requirements. As a general rule, the rear gas storage tank is twice as large as the front gas storage tank. In view of this, the pipeline must be configured in this order: air compressor gas storage tank primary filter cold dryer precision filter - storage gas based on the above storage The application of gas tanks in the gas path, manufacturing gas storage tanks also have configuration requirements: the cylinder material has good plastic toughness, uniform force, reasonable stress distribution, safety signal holes on the cylinder to ensure safety; the inner cylinder is corrosion-resistant Good material, and stress-relieving heat treatment, no hydrogen sulfide stress corrosion; finite element analysis method is used for fatigue analysis design to ensure equipment fatigue resistance. Plane topology and shape optimization design (Shenyang Sany Heavy Equipment Co., Ltd., Shenyang 11002 waste material, saving manufacturing costs, has a good promotion value. The planer is the basic component of the working mechanism of the plow. It undertakes the most basic plowing and supporting functions. The bottom is connected with the plow traction component. The traction plow is running and the upper part can be installed for adjustment. The height of the planer is increased, and the height of the planing head is adjusted. Due to the harsh working environment of the planer, complicated working conditions, diverse forces and uncertainties, and the speciality of coal mine production, the underground equipment often adopts a large safety factor and presents waste of resources. In this paper, with the purpose of reasonable weight reduction, under the premise of ensuring sufficient safety, the component structure is optimized to reduce material waste and manufacturing cost. 1 Topology optimization analysis process of the planer Before the topological optimization analysis of the planer, the parametric modeling is first carried out, the necessary reduction of the model, and the meshing, material properties and boundary conditions are applied to determine the optimization. Parameters and optimization goals. The topology optimization analysis is performed as shown in the flow chart. 2 Topology optimization analysis of the planer The shape topology optimization calculation of the planer model aims to reduce the weight on the basis of ensuring that it meets the normal working conditions, which makes the planer structure more compact and reduces the manufacturing cost. The software used in the analysis is the rapid analysis tool AWEDesign fund project: the National High Technology Research and Development Program (863 Program) funded project; Liaoning Province Science and Technology Innovation Major Project – Automated Plowing Machine Complete Equipment C20130500J). Limited company, engineer, graduate student of Harbin Institute of Technology, is now engaged in research and development and application of complete sets of equipment for fully mechanized mining and plowing. 5 Storage and maintenance of gas storage tanks There is a certain danger in the gas storage tanks, which requires maintenance. This will improve the efficiency of use, prolong the service life and ensure safe operation. Keeping the intact anti-corrosion layer of the gas storage tank, the working medium is corrosive to the material of the container body, and measures such as painting, spraying, electroplating and lining can be used to prevent the corrosion of the medium to the container. Every effort should be made to eliminate the chemical corrosion of the material in the tank body under certain conditions. Practice has proved that many gas tank accidents Yiyi are caused by neglecting maintenance during the stoppage operation. In a sense, the gas tanks that are not well maintained during the period of decommissioning are even more expensive than the normal use of the topology optimization flow chart expllel, using its topology optimization function to obtain the planer structure under the condition of applying external force to reduce The material weight is a state variable and ensures a topologically optimized shape with maximum structural stiffness. AWE defines topology optimization problems as well as defining other linear elastic structure problems. The user needs to define the material properties G single modulus, Poisson's ratio, material density, etc., select the appropriate unit type for topology optimization, generate a finite element model, and perform the following two applications according to the judgment requirements of the specific topology optimization problem. Analysis: 1 Apply load boundary conditions to do single-load or multi-load linear structure static analysis;) Apply external conditions for modal analysis. The analysis used herein makes the multi-loader damage faster by applying load boundary conditions because the deactivated pressure vessel is not only corroded by residual media in the uncleaned container, but also corroded by the atmosphere. Therefore, pay attention to the maintenance of the gas tank during deactivation. We are through the PP material, the production
