Shanghai Ingersoll Rand Compressor Co., Ltd. has made great achievements in the automotive industry and established long-term good cooperative relations with well-known automobile manufacturers and component manufacturers such as Volkswagen, General Motors, Toyota, SAIC, FAW, and Dongfeng.
Take a well-known automobile production enterprise as an example. In the new plant project with an annual output of 300,000 vehicles, the assembly, welding, painting and other workshops use a large amount of gas. The normal working pressure requires 7.5 bar (lbar=105Pa>, and another high pressure. The gas requirement is 14bar. Ingersoll Rand started the project design stage and conducted several targeted technical communication with the planning department of the plant. Combined with the layout model imported from abroad and the energy-saving management concept, it recommended the centrifuge. And the oil-free screw machine, which is a product that has obtained the German TUV certification level 0 air certificate at the same time, has many users and good reputation in the industry. In addition to the advantages of the product itself, it also designs a personalized overall system for the user. The solution is to use the centrifugal unit as the main unit to supply air in the low-pressure air system, and to configure the frequency converter with the oil-free screw to meet the high requirements for air quality; in the high-pressure air system, two injection screw units are used as spares. And configure the inverter to meet its energy saving requirements.
Users agree and eventually adopt this solution. Ingersoll Rand won the contract with a total value of more than 10 million with professional compressor technology support and efficient energy-saving solutions, which means that Ingersoll Rand's iconic project in the automotive industry has added A beautiful stroke.
With the rapid development of China's automobile industry, Ingersoll Rand will continue to focus on product innovation, and continue to inject zero-gas consumption regeneration technology into the development of the automotive industry. The application on the dryer has been recognized by more and more application cases. And is being developed. One case for meeting a 40 pressure dew point is the Atlas Copco Centrifuge ZH and the Zero Gas Consumption Compressed Heat Dryer ND used in an iPhone electronics factory. This is a unique energy-saving application based on analog selection. The ND series is Atlas Copco's most advanced energy-saving compression heat dryer, which takes full advantage of the heat of compression to regenerate the sorbent to replace the energy normally required to consume the finished compressed air or electric heater to complete the regeneration. This saves a lot of operating costs; and the entire system does not have any loss of regeneration gas, the technical characteristics are compared in the table below.
Content drum type compression heat dryer double tower compression heat dryer operation continuous cycle time switching gas consumption adsorbent solid / no dust particles / dust noise small large pressure reduction bureau dew point no fluctuation switching easy fluctuation control automatic synchronization Passive also provides a high-tech zero-gas consumption compression dryer XD series and zero-gas consumption blast dryer BD series products, which can meet the "20/-40/-70C pressure dew point, respectively, has been used extensively. Leading companies in the pharmaceutical, electronics, tobacco, automotive, photovoltaic and food industries, such as Novartis, Foxconn, Shanghai Tobacco, Volkswagen, Hairun Photovoltaic, Wahaha, etc. Among them, BD+ and XD have zero gas consumption compression heat dryer ND passed the actual test of the National Compressor Refrigeration Equipment Quality Supervision and Inspection Center of Hefei General Mechanical and Electrical Products Testing Institute, and proved to be no regeneration gas loss, ie zero gas consumption. .
With the continuous application and promotion of zero gas consumption regeneration technology, zero gas consumption energy-saving system will become a new application design direction in the field of compressed air purification.
At the State Council executive meeting hosted by Wen Jiabao of Zhejiang Kaishan Group, the National Emerging Strategic Industry Development Outline was adopted. The outline plans seven emerging strategic industries, of which the energy conservation and environmental protection industry is the first among the seven emerging industries. The core of the energy conservation and environmental protection industry is to achieve efficient energy use and gradient applications. The two-stage compression screw air compressor developed by Dr. Tang Yan, a “Thousand Talents Program†expert, has energy efficiency exceeding China's Class I energy efficiency, which is 12% higher than similar products of the most famous brands in foreign countries. Dr. Tang Yan led the development. Another product, the ORC screw expansion generator, can convert only 85C of waste steam and waste hot water into electricity, completing a breakthrough in the key core technologies listed in the energy conservation and environmental protection industry plan.
The technology has a installed capacity of 10 million kW in the steel industry alone.
In addition to waste steam and waste heat power generation, ORC screw expansion generators are also widely used in low-grade thermal energy generation such as geothermal, solar energy and bio-energy. The market prospect is very broad and the economic and social benefits are huge.
Kaishan Company has introduced a number of high-tech products with low-cost, high-pressure series screw air compressors, screw-expansion power station rod vacuum pumps, centrifugal air compressors and refrigerant compressors, which are energy-efficient and have independent intellectual property rights and core technologies. The world of energy efficiency is leading. Products exported to Australia, South America, Europe and the United States have been highly praised by users.
Chengdu Chengfa Keeneng Power Industry Co., Ltd. is a large-scale axial compressor with the main intellectual property rights. The ACL80 axial compressor is installed in the factory of AVIC Chengfa Group (hereinafter referred to as Chengfa Keeneng). Successfully filled the gap in the domestic independent development of large-scale axial compressors, marking the official entry of Chengfa Kecan into the large-scale axial compressor market.
In 2008, Chengfa Branch started the development of ACL80 axial compressor and began to enter the large axial compressor market. At the end of 2009, the company received the first ACL80 axial flow pressure q-)gm general machinery
Investment casting technical flow process
The silica sol casting process also called precision investment casting process. It is a less cutting or no cutting casting process. It is an excellent technique in foundry industry. Its application is very extensive. It not only applicable to various types, various kinds of alloy and casting, and produce the casting dimension accuracy and surface quality is higher than other casting method, Even other casting method can not do the complex, high temperature resistant, not easy machining castings, all can be used for investment precision casting process.
The investment casting process, it is a process that use fusible materials make soluble model, and coated with several layers of tailor-made refractory coating on the surface, after drying and hardening become a whole shell, melt the shell model by steam or hot water. Then put the shells in the sand, filling dry sand in all round and modeling. Finally roasting it based on high-temperature in the furnace, the shell after roasting, and getting the casting part after pouring molten metal.
The investment casting process can produce High precision dimensional parts, generally can reach to CT4-6(sand casting is CT10-13, die casting is CT5-7). Due to the complexity of investment casting process, there are many factors influencing the casting dimension accuracy. Such as shrinkage of mold material, deformation of the casting, Shell heating and cooling line quantity change in the process, alloy shrinkage and deformation of castings in the solidification process. The surface finish of investment castings is higher than the ordinary casting, can reach to Ra1.6~3.2.
The greatest advantages of investment casting is casting parts have high dimensional accuracy and surface finish, so it can reduce the mechanical processing. The another advantage of investment casting method is that it can cast all kinds of alloy and complex casting part, special casting high temperature alloy casting part.
