The Grand Canal Heavy Truck commenced operation on October 26, 2009. As of September 2010, the Grand Canal Heavy Trucks sold a total of more than 5,000 vehicles, with sales of 1.2 billion yuan. As time progresses, all aspects have been improved. The first is quality improvement and improvement. The Grand Canal Heavy Trucks not only required that they do a good job of quality, but also required the quality of parts and components suppliers. Although the scale of production of the Universiade heavy trucks is small, many parts and components suppliers believe that the Universiade heavy truck is a potential stock, since it is considered a potential stock. Well, in order to achieve a win-win situation, quality must be improved. According to the feedback from the current market, the departments of the Universiade Automotive Manufacturing Company, such as the service department, sales department, technical department, quality inspection department, procurement department, finance department, and audit department, jointly report statistics once a month. Three months in a row, summarize which product has the most quality problems? If the quality ranks in the last ten for three consecutive months, cancel the cooperation. The long-term survival of the fittest, the rest are good. Therefore, if you want to cooperate, you can see that the Grand Canal Heavy Truck is a potential stock and you want to make money.
With strict requirements on the quality of parts and components suppliers' products, coupled with the efforts of their own efforts and technical coordination, the quality of the Universiade heavy truck will become better and better, allowing customers to use products with confidence. Second, the Universiade heavy truck has trained and trained its workshop workers for nearly a year. Their proficiency has been greatly improved. From the initial sale of dozens of vehicles, a maximum of a few hundred vehicles, but with the continuous increase in the number of heavy truck sales, shop workers can now do 50 vehicles a day without overtime. In 8 hours, overtime work can be done in 100 vehicles. This is the second major change.
The third change, from the time of production to the current year. With the continuous development of the market, the original network service is zero, and there are only a dozen sales networks. The current sales network has reached more than 100, and the service network is also increasing.
The fourth change, now you can often see the Grand Canal heavy-duty truck running on the highway, this will have a certain consumption effect, and can increase the visibility of the Grand Canal heavy truck. So now there are many mines admired to purchase the Universiade heavy truck, and the orders are just dozens of vehicles.
It is precisely because the Universiade Automotive Manufacturing Co., Ltd. attaches great importance to product quality, strict quality control, only to establish a good reputation and credibility. The Grand Canal Heavy Trucks will lay the foundation for a year, gradually expand the scale of production, and sales volume will continue to increase. At the same time, Universiade Heavy Truck also achieved a leap-forward development in terms of product quality, technology development, and market expansion.
The Grand Canal Heavy Truck is still a new recruit for China's heavy truck market. In just one year, it has achieved an impressive sales of nearly 6,000 units. Although the technology of the Grand Canal Heavy Truck cannot be said to be particularly advanced, I have made a big car manufacturing company. Every employee in the company is full of passionate work. First of all, they love this industry. Second, Universiade Motors provides them with a platform to show their abilities. Finally, it is through the reward mechanism to realize his own value. Together these are the advantages of the Universiade Motors. In addition to its own efforts, the Shanxi provincial government attaches great importance to the Universiade heavy truck. The provincial party committee secretary and governor visited the site several times and provided guidance. Shanxi Province is the largest coal province in China, but it is not the first strong province nor the first rich province. At present, the Shanxi Provincial Government proposes a grand strategy of transformation and development and leapfrogging development, and recreating a new Shanxi through the transformation.
Shanxi needs to walk on multiple legs and cannot go one way. Reliance on resources is limited, and innovation and transformation can be said to be unlimited. Everyone thinks that the auto industry is a potential stock, which is in line with the current transformation and development in Shanxi, and has great potential. The current slogan of Shanxi Province is to transform, cross and double. Under the leadership of the provincial party committee and the provincial government, Universiade Motors is a local company. Its goal is to recreate a new Shanxi and take the lead in realizing a doubling of doubling, contributing its own strength to rebuilding a new Shanxi.
In 2011, Universiade Automotive Manufacturing Co., Ltd. will respond to the call of the Fifth Plenary Session of the 17th CPC Central Committee. In the second phase of the proposed "Twelfth Five-Year Plan", the company plans to invest 2 billion yuan, and it will form an annual output of more than 100,000 units after it is put into production. Construction has now begun. With the sales target of 20,000 units in 2011, the Universiade will strive to complete an annual production target of 50,000 heavy trucks within 3 to 5 years and achieve an annual output of 100,000 vehicles within 7 to 8 years. Since the end of 2008, the state has started four trillion yuan of investment, launched a series of policies such as the ten major industry rejuvenation plans, and the effect has gradually emerged. The situation of China's heavy truck market has improved. Therefore, 2010 is the golden year for China's heavy truck market, and it is also a good year for many heavy truck companies. 2011 may not be as big as 2010, but there will be a small increase.
Aluminum extruded finned tubes using the form of the base tube covered with aluminum tube(the base tube can be carbon steel, stainless steel, copper) through machine extrusion, forming a tube fin, the fin base and the tube outer wall is close fitting, this fin tubing control can make finned tubes with high heat transfer coefficient and heat transfer performance.
Aluminum extruded finned tubes, also called [integral finned tubes" using the form of the base tube covered with aluminum tube(the base tube can be carbon steel, stainless steel, copper) through machine extrusion, forming a tube fin, the fin base and the tube outer wall is close fitting, this fin tubing control can make finned tubes with high heat transfer coefficient and heat transfer performance. Extruded finned tube can be made of iron, copper or aluminum tube by compound rolling, which has the advantages of tight bonding, small thermal resistance, good heat transfer performance, high strength, small flow loss, strong anti-corrosion performance, not easy to deformation under long-term hot and cold working conditions, long working life and so on.
Extruded finned tube manufacturing process
Pipe line--compressing or rolling--strip peeling--washing--pressure test--blast blowing--packaging.
The extruded fin tube is formed by a bimetallic tube consisting of an aluminum outer tube and an inner tube of almost any material. The fin is formed by rolling the material from the outside of the outer tube to provide an integrated fin with excellent heat transfer performance and life. The extruded fins provide excellent corrosion protection for the base tube.
The production method of the composite finned tube mainly includes the extrusion method: the bimetallic composite tube is lined with a mandrel, and driven by the rotation of the roller blade, the composite tube is processed on the outer surface through the cavity formed by the rolling groove and the core head Out fins. The heat transfer tube produced by this method is an organic whole with its outer tube and fins, so there is no problem of contact heat loss, and it has good performance and high heat transfer efficiency.
Extruded finned tube advantage
Compared with the ordinary wound finned tube, the contact thermal resistance remains stable in a large range with the temperature change, so the heat transfer performance of the bimetallic aluminum extruded finned tube is better than the spiral fin tube in the limit tube wall temperature range.
In addition, compared with the coiled tube, the bimetallic aluminum extruded fin tube has outstanding corrosion resistance and high strength, it can withstand 4.0MPa water pressure cleaning, the fins still do not fall down, the base of the bimetallic aluminum extruded tube. The tube can be selected according to the corrosion of the fluid in the tube and the processing technology. The base tube can be carbon steel, copper, stainless steel, etc.
Extruded finned tube applications
Extruded finned tubes are the main equipment for air coolers and are commonly used as heat exchangers in power plants (electric, nuclear, thermal and geothermal). Steam condensate system. Chemical and petrochemical industries. Food processing plants and refrigeration technology. Industry (steel mills, incinerators, gas compression facilities).
