"Last year, Shandong exported 7.834 billion U.S. dollars worth of tires, an increase of 54.06% over the previous year. The value of exported tires is already close to 50% of the national total." On April 13, we talked about the export success of Shandong tire companies. Shandong Rubber Zhang Hongmin, President of the Association of Trade Unions, was overwhelmed with excitement. “Under the influence of the US special security case, in the face of the general downturn in the national tire industry last year, especially the sharp decline in exports, Shandong Province is able to stand out in the country. It is tire companies in the province We will carry out technological innovations and accelerate the transformation of business development models."
Zhang Hongmin told the reporter that as the largest tire province, Shandong tire companies rely on the implementation of high-end, high-quality, and high-efficiency development strategies and regard improving the capability of independent innovation as an important measure to enhance their core competitiveness. In 2011, among the top 75 tires in the world, there were 24 companies in mainland China, of which 11 were in Shandong, accounting for 45.8% of the top companies. Last year, Shandong tire companies produced a total of 156.27 million radial tires, which accounted for 39.3% of the country's total output. Among them, 45.526 million radial steel radial tires accounted for 50.3% of the country's total output; 110.444 million radial steel radial tires, accounting for the country's total output. 36%, the proportion of semi-steel radial tires in the country increased by 2.11% compared with 2010.
In recent interviews, the reporter also deeply felt the fact that technological innovation has made Shandong tire companies rejuvenate.
Triangle Tire Group Co., Ltd. is currently the country's largest integrated production, sales, research and integration tire company. In the field of tire R&D and manufacturing, major engineering breakthroughs have been made in the technology and equipment development for giant engineering radial tire production, and a number of scientific research achievements have reached world-class standards. In view of the high energy consumption of the rubber refining process, Delta Group draws on advanced experience from abroad and adopted the low-temperature continuous mixing process in the domestic tire industry, saving more than 27% energy compared to the traditional multi-stage mixing process and increasing tire wear resistance by 10%. Above, increase production efficiency by more than 200%.
On March 26 this year, the Shandong Provincial Department of Science and Technology, the Shandong State-owned Assets Supervision and Administration Commission and the Shandong Provincial Federation of Trade Unions jointly announced the second batch of innovative enterprises in Shandong Province. The Triangle Group was identified as a provincial-level innovative enterprise.
“We are actively planning the technological innovation sector and plan to invest more funds during the “12th Five-Year Plan†period, specifically for scientific research work, to further increase the level of independent technical research and development of tires, and to work hard in accordance with the principles of low-carbon, green, environmental protection and high efficiency. Realize the circular economy to drive the development of the enterprise.†Triangle Group technician Wang Baojiang told reporters excitedly.
“We have adopted a carcass electron radiation meter presulfiding technology in the newly-built 12 million high-performance semi-steel radial tire projects. This technology can reduce sidewall thickness, reduce rubber consumption, and improve tire movement. Balance uniformity, improve the appearance of pass rate. After tests have proved that using this technology can reduce the weight of the carcass 1.5%, only this one, annual savings of more than 540 tons of plastic material, and more to create more than 20 million yuan."
Due to its focus on the development of new products, the company's UHP tires have created the lowest domestic (25 series) and highest speed (350 km/h) records. The tires produced by the company have passed the review of GM and Ford suppliers, and achieved a breakthrough in domestic tires for international leading automotive companies.
Director Wang of Shandong Jinyu Tire Co., Ltd. told the reporter that the company has invested more than 20 million yuan in the newly-built 15 million high-performance semi-steel radial tire projects, and established the tire manufacturing execution control system, the MES intelligent platform, during the entire production process. It has truly realized the paperless operation management path of the enterprise. Through the advanced control function of the MES system, it completely eliminates the misuse of materials. This system is the first application of a domestic domestic tire production enterprise and has a good demonstration effect.
“We have pioneered the development of color car tires at home and abroad,†Wang Hai, president of Qingdao Double Star Group, told reporters excitedly. Wang Hai said that the Double Star Group has independently developed and now has the core technology for producing colored tires and has applied for patents. Since carbon black is not used, colored tires not only increase the environmental performance of car tires, but also change the notion that tires are all black in people's traditional impressions. After the products are put on the market, they are in short supply.
"We have developed three technologies for all-steel radial tire water-repellent and anti-puncture technology, all-steel radial tire triangular core heat paste flattening technology, and mining engineering tires and high wear resistance and puncture resistance technology. The new product and new technology of the Committee were identified and accepted.†Liu Yonghua, chairman of Shandong Yinbao Tire Group, also told reporters. He said that because of its persistence in science and technology, Yinbao Tire has become the only domestic tire brand for GAC Hino that is exported to Europe, in addition to supporting domestic well-known automakers such as China National Heavy Duty Truck, Shaanxi Automobile, and Beiqi Foton. North America, Middle East, Southeast Asia and other international markets.
The single-screw pump is a rotor-type positive displacement pump, which relies on the intermeshing of the screw and the bushing to produce volume changes in the suction cavity and the discharge cavity to transport liquid. It is an internal meshing closed screw pump. The main working parts are composed of a bushing (stator) with a double-ended helical cavity and a single-ended helical screw (rotor) meshing with it in the stator cavity. When the input shaft drives the rotor to make a planetary rotation around the center of the stator through the universal joint, the stator-rotor pair is continuously meshed to form a sealed cavity. - The rotor pair is transported to the extrusion end, and the medium sucked into the closed cavity flows through the stator without being stirred and destroyed. Single screw pump classification: integral stainless steel single screw pump, shaft stainless steel single screw pump
