Truck differentiation: South Light North weight weakens local area. The ancient Chinese transportation method is that the ship is mainly in the south and the horse is the main in the north. It also has the saying of "South Ship North Horse". Previously, in northern China The land transport is the mainstay, while the south is dominated by water transport; China's modern industrial layout has the regional characteristics of the South Light and the North. It is said that the southern light industry is relatively developed, and the northern China is dominated by heavy industry.
Coincidentally, in the last century, in the Chinese truck market, the north was dominated by medium and heavy trucks, while the south was dominated by light truck brands, which traced the source, which is inseparable from China's industrial development. China's northern coal, petroleum, iron ore and other mineral resources are abundant, so the industrial structure dominated by heavy industries such as mining, metallurgy and machinery manufacturing is gradually formed, which leads to the development of special heavy trucks for mining and logistics vehicles for transporting bulk cargo. The southeast coastal areas are not as good as the northern countries in terms of traditional resources. Therefore, economic development is the road to light industry and small commodity markets. The demand for medium and short-distance transportation is much higher than that of the north. Therefore, the demand for light-duty vehicles is much higher than that of the northern regions.
In the 21st century, China's economy has begun to transform, and from the extensive development model to the intensive transformation, sustainable development has also been put on the agenda. In the tide of transformation, the pattern of the south and the north of the truck market has also been broken, showing a trend of North-South integration, most notably the emergence of the three emerging economic belts of Beijing-Tianjin-Hebei, Yangtze River Delta and the Pearl River Delta. The rapid development of the economy has brought more infrastructure projects and logistics transportation needs than other regions. It has also generated huge market pull for high-end light trucks and high-end heavy trucks. The three economic belts have gradually become the battleground for truck manufacturers to develop their markets. And many truck companies have begun to shift from local domestic sales to occupying three emerging economic regions.
Two misunderstandings: The neglected Bentham companies are the three most important elements in the march. The shopping malls, such as the battlefield, are no exception in the truck market. When it comes to the geographical characteristics of the truck market, people often misunderstand some Bentham companies, mainly in two aspects. On the one hand, Bentham enterprises are biased. If you want to enter other regions, the first thing to solve is the products. Transportation costs; on the other hand, the issue of brand awareness, because the geographical factors of the factory often lead to the company's brand will be limited to the local, it is difficult to expand to other areas.
Among the misunderstood Bianyi enterprises, the most representative is the Shijun commercial vehicle. Although it is located in the Yunnan area, it belongs to the borderless enterprise, but the Shijun commercial vehicle has used the market performance in recent years to crack. Misunderstanding of the geographical factors.
When everyone is still vying for the various triangle market in China, the Shijun commercial vehicle brand has intensively cultivated in Yunnan and Guizhou, and has become a household name. It has also stepped up the pace of going abroad. It is understood that in 2014, Shijun commercial vehicle exports Overseas trucks increased by 32.7% year-on-year, while export sales increased from 557 million in 2013 to 750 million.
Strong data performance is a testament to market performance, but data can only represent the past. At the end of 2014, Shijun Commercial Vehicles launched the first domestic sedan-oriented and sporty truck brand - PROJEN heavy truck and PROJEN light truck. Two new products that target the target to higher coordinates.
As the first high-end truck enterprise in China to apply 3D printing technology, Shijun Commercial Vehicle is leading the industry with new directions in its own actions, advocating technology to create the future and actively developing core technologies. With the rise of new car companies represented by Shijun Commercial Vehicles, the misreading label of Bentham Enterprises is being revised, and what is the competition of the former Bentham companies in the future market competition? Waiting for you!
Ball valves are usually used for shutting off or connecting the medium flow.
The maximum permissible leakage of the valve with non-metal elastic seals is zero, and that of the Ball Valve with meal seals is 0.1xDNmm3/s.
Therefore, acceptable valves with metal seals possibly have slight leakage. Hence, in the applications where there must not be any leakage,especially at the pipeline ends, ball valves with soft seals should be used.
Nominal pressure of brass ball valve is 1.6MPa, 2.0MPa and 2.5MPa. When the ball valve is used for saturated steam, the pressure of the saturated steam should be ≤0.6MPa.used.
