In the MPV field, JAC Refine is also the first manufacturer to introduce diesel vehicles in China. On August 29, at the Small Car Forum held in Guangzhou, Deputy General Manager Jianghuai Yun of JAC said that within five years, Ruifeng Diesel Commercial Vehicles will More than gasoline vehicles, occupying half of the Ruifeng commercial vehicle. In the first half of this year, Ruifeng diesel vehicles have already accounted for 15% of total sales, and in some provinces even as high as 60%. Coincidentally, on August 20, the Audi A6TDI diesel sedan was launched nationwide. At this point, FAW-Volkswagen launched a full range of diesel passenger cars including Jetta, Bora, and Audi. The diesel car once again attracted people's attention. What will happen to diesel vehicles in China in the future, and will there be opportunities for rapid development? At this forum on the theme of “The Future of Diesel Passenger Cars in the Chinese Marketâ€, related industry experts and scholars discussed this issue. Passenger car diesel cars become a trend Wang Chaoyun believes that the diesel engine of passenger cars has become a trend in the international market, because diesel engines have a principle advantage in terms of environmental protection and energy saving compared with gasoline engines. Wang said that the proportion of diesel passenger cars in Europe is now close to 50%, while China is still very poor. Although diesel vehicles cost more than 10,000 yuan more than gasoline vehicles of the same grade, he believes that the cost can quickly make up for fuel savings. However, he also admitted that the current diesel vehicles still have the disadvantages of slow start-up speed and slightly louder noise. The recently released "Auto Industry Industrial Policy" proposes that the average fuel consumption of passenger vehicles in 2010 is expected to be 15% lower than that of today. Wang Chaoyun believes that this will bring great development opportunities to the evolution and development of China's diesel vehicles. In solving the problem of fuel consumption, diesel vehicles are more basic and advantageous than those with electric fuels and light industrial fuels. Due to the inherent prejudice of Chinese consumers on diesel vehicles, automotive experts and Wei An, an associate professor at South China University of Technology, believe that, first of all, as government departments must vigorously support the development of the diesel vehicle market, support and increase investment in policies; We must step up research and development to produce diesel vehicles that are fuel-efficient, energy-efficient, environmentally friendly, and have relatively low noise levels. Finally, the media should properly guide the consumption of diesel vehicles. The commercial vehicle is the best carrier for diesel power. The reporter learned that the current Chinese passenger vehicle market is almost a blank market except for a few companies such as FAW-Volkswagen, JAC Refine, and diesel engines. At present, domestic diesel vehicles are “on the account†in many places. "There are still many restrictions. Even most consumers don’t accept diesel vehicles enough. They think that diesel cars are black smoke and have a lot of noise. They always feel that they are not high enough. Faced with the various problems faced by diesel vehicles, Wang Chaoyun said that many Chinese companies do not dare to apply diesel vehicles to passenger cars. Of course, this may be due to various reasons, such as historical reasons. But the benefits of diesel cars can be understood through experience. In addition, in the promotion of diesel vehicles, in addition to the media and government departments, the production companies should also play the role of "a pioneering cattle" for the entire diesel vehicle market. Wang Chaoyun said that commercial vehicles have many convenient conditions for promoting diesel vehicles. Ruifeng's promotion strategy is to first highlight the economics of diesel vehicles. Through the use of commercial vehicles, diesel vehicles are not only economical, energy-saving, and environmentally friendly, but also attracting more private car owners. Participants believe that under the premise that the current public acceptance of diesel cars is not high, through the special nature of commercial vehicles, more consumers can realize the process of purchasing and effectively distributing diesel vehicles through personal experience. Huang Xu, the general manager of Tongda Ruifeng Store, said that from the perspective of sales, the Ruifeng diesel version was launched in less than a year, and the original sales of two or three units per month have now reached more than 20% of the total sales volume. From the market point of view, consumers gradually began to accept diesel vehicles. (Times reporter Zhu Zhuohua)
Winding Drainage Pipe
Winding Drainage Pipe
The performance characteristics of the HDPE winding structure wall tube are as follows:
1. The hot state of winding forming welding joint quality is high.
The flat material belt and U-shaped material belt extruded from the mouth die of the extruder in the melting state are evenly wound on the heated roller die according to the predetermined position, which ensures the quality of the fusion joint of the structure wall tube. In particular, in the structural design, the melt joint of the flat material belt is covered by a polyethylene-coated supporting tube, which improves the overall resistance to the external pressure of the product.
2. Good connection quality.
The pipe connection with excellent installation performance adopts the
embedded electric fuse in the socket with the same material socket welding
connection technology. It can achieve zero leakage, ensuring the same life span of the pipeline system and the safety of operation. At the same time, because the product under the condition of the same application as other tubes light weight, and is easy to transport, construction is convenient and quick, and can reduce the construction cost, in the range of applications, without a concrete cushion layer and concrete jaasiel groove can directly apply the tube after qualified, basically, stay do under excavation, side tube, while backfilling, simplifies the construction procedures, shortening the time limit for a project. During the project acceptance, the closed-air test is used instead of the closed-water test, which not only speeds up the acceptance but also saves the complicated work and a lot of test costs in the closed-water test
3. Good flexibility
High-density polyethylene winding structural wall pipe has macro flexibility, and the micro pipe section has strong rigidity and overall resistance to external pressure.
when used under heavy load road surfaces, it can ensure the safety of traffic. Due tothe flexibility of the pipe, it can also reduce the damage loss of the pipe to the minimum in the event of an earthquake, uneven surface settlement, and other geological activities. These characteristics improve the seismic mitigation ability of public facilities.
4. HDPE can be recycled, The main raw material of winding structure wall pipe
is green environmental protection products, such as high-density polypropylene, which doesn`t have any toxicity. There is no dye in the production process. The used pipeline can be 100% recycled. It is a green product of environmental protection.
5. Corrosion resistance, aging resistance, and service life span can be up to 50
years.
High-density polyethylene has the ability to resist chemical corrosion and
erosion. Therefore, when the winding structure wall pipe is conveying corrosive fluid or laying in corrosive soil, it does not need anti-corrosion treatment, and its performance is much better than other pipes. The product in the design process, chooses a reasonable product structure form, to ensure the service life span of the plastic pipe is more than 50 years, and no maintenance is needed in the life span.
6. Tube inner wall roughness, large water transfer around the structure of the
wall tube. Product inner wall roughness N is about 0.010, so the transmission of fluid has lower friction, compared to other products such as cement pipe with a similar diameter the water transfer is greatly improved. Therefore, the smaller HDPE tube can replace the larger cement pipes. In application, under the same conditions, using a wall pipe winding structure can have better reliability compared to the traditional pipe material. The comprehensive benefit is obvious, especially in the narrow construction site, high building density, underground pipeline, complicated traffic busy roads, and acid soil.
