Twelve tons of behemoths have to climb up to a 60° slope and down to a pit of 1.5 metres deep. On October 30, 2010, such thrilling performances were being performed at the Shaanxi Steam Cup 2010 National Super Truck Contest in the Shaoguan Logistics Port Finals.
The DeLong F3000, powered by racing drivers, is equipped with a 500-horsepower engine specially developed by Weichai for the National Super Truck Contest. The prototype of this racing engine is Weichai's Lanqing WP12 high-powered engine.
Obviously, big horsepower has become the mainstream trend, both on the field and in the market. At present, domestic large-scale transport vehicles of more than 500 horsepower are almost entirely occupied by imported vehicles. The vast majority of domestic high-powered tractors are concentrated in 400 horsepower. Weichai's launch of 500 horsepower has reached the limit of domestic cars.
This energy-saving and environmentally-friendly diesel engine, which meets Euro III emission regulations and has the Euro IV potential, was developed in cooperation with the Austrian AVL company. Its fuel consumption, emissions, noise, and reliability are among the world's advanced standards. Since Weichai Power officially launched Lanqingguo III diesel engine in 2005, it has been recognized by the market for energy conservation, environmental protection, efficiency, and speed.
The super destructive test on the playing field makes Lan Qing more emboldened when facing the market. Judging from the track, the uphill slope of the Three Peaks can reach a maximum of 60 degrees, and is a continuous hump of 4 meters, 6 meters, and 8 meters. In this way, DeLong Racing had to repeat more than 24 times in 2.5 hours.
The depth of 1.5 meters in the sand pit is another test. The car rushed in at a speed of around 20km/h, nearly vertically falling into the pit, and its impact force was equivalent to several times or even ten times the weight of the car. It was like a car with a thousand crowns for the car chassis, and for the engine, It is tantamount to a purgatory. No wonder some people jokingly claimed that the National Super Truck Cross Country Race is the first test ground for Chinese trucks.
Heavy trucks equipped with a Weichai engine have provided tremendous support for the stable operation of racing cars and racers. He moved to nine cities across the country for two years, traveled tens of thousands of kilometers, and went through 18 preliminaries and finals. Despite the scars of racing skin, his heart was still strong.
It is worth mentioning that on June 21 this year, Weichai Group held a 100 billion-level green power R&D and manufacturing base and a 1.5 million-strong high-power diesel engine strategic planning conference in Weifang, Shandong Province, to announce the 5-8-10 strategic target, namely 2012. The sales revenue will be 50 billion yuan, 80 billion yuan in 2015, and 100 billion yuan in 2020. In order to achieve this strategic goal, Weichai must lay a solid foundation, consolidate and further expand its advantages in the heavy truck market in traditionally advantageous areas, so that it can do a better job in deploying and building a full range of engine platforms in all areas.
It is understood that the existing production capacity of heavy truck companies has reached 1.5 million, and it is expected to exceed 3 million by the end of the “Twelfth Five-Year Plan†period. If Weichai Power currently accounts for nearly 40% of the market share in the heavy truck market, the demand for 10L or more engines for Weichai Power in the heavy truck market will reach 1.2 million units in 5 years. The introduction of an upgraded version of the Lanqing Power II generation in the medium and heavy markets will further expand the advantages of Weichai Power, and the test of the racing field will also help lay the foundation for the next 600-horsepower R&D battle for the domestic trucks. Continuous technology upgrades to enrich its brand connotation.
The harvest of Weichai in the cross-country truck race seems to underscore its more ambitious future.
Welded Bed Plate For Flanges Of Ship Pipe
The flange welded single-sided seat plate is mainly installed on the top, side wall and bottom of the cabin or cabinet as the entrance and exit of the cabin or cabinet. Valves, accessories or pipes can be installed directly on the single-sided seat plate.
Flange welded single-sided seat plate is suitable for seawater, fresh water, oil, air and steam pipelines below 300 °C. The commonly used nominal diameter is 15~150 mm, and the nominal pressure is lower than 1.6 MPa. The shape of the single-sided seat plate is similar to the corresponding lap-welded Steel Flange.
Flange welded double-sided seat plates are generally used when pipelines pass through decks and tanks, and the two sides of the seat plate are respectively connected to valves, accessories or pipes.
Compared with the single-sided seat plate, the double-sided seat plate has an extra shoulder and double-sided mounting stud bolts. The outer diameter of the shoulder is 10~20 mm larger than that of the corresponding flange, and the thickness of the shoulder is 6~12 mm.
Its scope of application and other structural dimensions are basically the same as those of the single-sided seat plate.
The manufacturing and installation methods of the flange-welded double-sided seat plate are basically the same as the single-sided seat plate, but when the screw holes are drawn, the positions of the upper and lower screw holes of the seat plate must be staggered from each other and must not overlap; deck or bulkhead The diameter of the hole on the top is 2~3 mm larger than the diameter of the seat plate.
