Application of vacuum technology

Metallurgical industry: The vacuum technology used in the metallurgical industry includes molten steel vacuum processing, vacuum melting, vacuum induction melting, induction shell melting, vacuum arc remelting, etc. Among them, the vacuum treatment of molten steel is a very important aspect of the metallurgical industry. This technology is mainly used in the atomic energy industry, aerospace technology, ocean drilling technology, gas engine technology, automobile industry, aircraft manufacturing, high-speed trains and other high-tech industries to control and process certain elements in steel, and to The life and reliability of materials put forward higher and higher requirements.

Process Parameters Of Vacuum Brazing Heating And Cooling

Electronics and microelectronics industry: Microelectronics technology requires smaller and smaller electronic components and circuits, and higher integration requirements. This is inseparable from the application of vacuum technology, especially the microfabrication technology of VLSI. The formation of geometrical structure, ultra-thin layer growth technology, and particle beam injection technology all require a high-quality and clean vacuum environment, which shows its development Dependence on vacuum technology and equipment.

Detailed Explanation Of Gas Carburizing Process

Machinery manufacturing industry: Vacuum heat treatment refers to a new type of heat treatment technology that closely combines vacuum technology and heat treatment technology. Its treatment of tools, molds and precision couplings can increase the service life and accelerate the adsorption and reaction process of chemical heat treatment. In addition, its own technological operation is flexible and pollution-free has become a common treatment method in the industry.

Introduction Of Vacuum Hot Pressing Furnace Performance

vacuum pump in gas drainage Gas accident is the most important thing in coal mining industry in recent years. Dozens of innocent people can be killed in a mine accident. Therefore, the safety of equipment in coal mining industry can not be ignored. There are several basic forms of gas drainage by water ring vacuum pump / compressorAccording to the relationship between coal mining and drainage: pre pumping before mining, that is, the drainage of coalbed methane from the undeveloped coal seam. Because the mining area is wide and the pipeline is long, it usually has dozens of kilometers. The working environment is bad, so the water ring vacuum pump / compressor is required to have large air volume, high vacuum degree and reliable operation. Now the water ring vacuum pump / compressor is designed and manufactured with international advanced technology, and the gas volume can reach 500 ~ 70000m3 / h, which can fully meet the needs of coal mining industry. This pumping method has gradually become the mainstream. This method not only becomes the guarantee of safe production, but also becomes a new clean energy, which has strategic significance for China, a big coal country. Pumping while excavating and mining while pumping, that is, CBM drainage in the process of coal seam mining. After mining drainage, namely abandoned mine, mining roadway CBM drainage.The drainage method is divided into: drilling drainage, drilling coal seam, and using loosening technology to increase the release area and conduction of coalbed methane, so as to make the rapid release of coalbed methane. Reduce the release in the process of excavation. This method has good effect and high utilization rate of coalbed methane. Generally, water ring vacuum pump / compressor is used for pumping. Roadway method drainage, the goaf roadway, mining roadway gas drainage, to ensure the safe concentration. It includes surface vertical well pumping, mixed pumping, etc.Roots Vacuum PumpSSR Roots Type BlowersDry Type Oilless Vacuum Pumps

Main function of pump body The pump body is also known as the pump housing. The main function of the pump body is to close the impellers of various pumps and the medium to be transported in a certain space, concentrate the medium discharged from the impellers of the pump to the outlet pipeline, and convert a part of the velocity energy of the medium into the boosting energy, so as to speed up the velocity of the outlet pipeline, and increase the pressure to achieve the purpose of constant flow of water energy at the low place to the high place. The pump body is also a part that bears the medium pressure.There are three kinds of commonly used pump bodies: volute type double suction centrifugal pump: the shape is very similar to the snail's shell, the volute has different cross-section and gradually expanded flow channel, and the shape and size of the flow channel have a great impact on the flow head of the pump. As shown in Figure 2-7Pump body with inducer device: the pump body is a rotating body model, and there are several flow channels with inducer structure outside the impeller in the pump body.Double layer pump body: a cylinder shaped pump body is added outside the general pump body, which is called double layer pump body, This kind of pump body can usually play the role of heat preservation or temperature reduction. For example, when the sewage pump is automatically stirred to deliver high-temperature liquid, if you want to keep the temperature unchanged, you can apply hot water or heat preservation liquid to the outer layer to keep the liquid in the pump body from falling. If you want to reduce the temperature, you can apply cold water to the outer layer to also play the role of temperature reduction.Dry Type Oilless Vacuum Pumpsindustrial vacuum pumps,vacuum furnacesDry Screw Vacuum Pump
