As the world's largest auto market, the Chinese market has long been a major market for international giants to compete, and it has also become the main source of their profits. With the rapid and rapid rise of car sales, the importance of the Chinese market to international giants is also increasingly prominent. Among the international giant auto companies, the situation with the Volkswagen Group is more pronounced.
Sales volume: total sales continue to climb the Chinese market significantly
In terms of sales volume, Volkswagen Group’s global sales have continued to climb in recent years. According to Gasgoo.com's data, by 2013, Volkswagen's global sales amounted to 9,728,300, compared with 7,278,400 in 2010, and the cumulative sales increased by 33.7% during the three years. For this year, the Volkswagen Group expects annual sales to exceed 10 million units. In the six months that have passed, its performance has also been very good. It has increased by 6.9% to 5.207 million vehicles, and its mission has exceeded half.
Volkswagen's business sales in China have played a significant role in boosting sales. In recent years, the growth rate has exceeded the group's total sales growth rate, and the contribution rate of sales in the Chinese market has also increased year by year. In 2010, Volkswagen's sales in China (herein referred to the total sales volume of Volkswagen's two joint ventures in China) were 1.871 million, which accounted for 25.7% of the Volkswagen Group's global sales. In the following three years, sales of Volkswagen China business maintained double-digit growth. By 2013, Volkswagen’s sales in China had increased by 62.4% to 3.038 million units, and the contribution rate had climbed to 31.2%. In the first half of this year, the contribution of sales volume in the Chinese market rose again to 35.5%, and the sales volume increased from 1.517 million units to 1.847 million units, a year-on-year increase of 21.8%, which was far higher than the 6.9% growth of the Volkswagen Global.
Operating profit: China's business growth and total operating profit ratio exceeds 40%
With the ever-increasing sales volume, Volkswagen’s operating profit has also been increasing for the past four years, but the increase is not significant. In 2010-2013, except for 2010, the overall operating profit of the Volkswagen Group was only slightly higher than 3% in the remaining years and reached 11.671 billion euros in 2013. In the first half of this year, the VW Group’s operating profit also increased by only 7.0% to 6.186 billion euros.
The profit of the Volkswagen China business increased significantly, and its ratio with the total public revenue rose sharply. Although VW’s operating profit in China’s business is not directly included in global profits due to its share-to-share ratio, it can be used as a reference value under the equity method. According to the data calculated by the equity method, the profit of the Volkswagen China business continued to grow rapidly. In 2010, Volkswagen’s China business operating profit was 1.907 billion yuan, and it climbed to 4.966 billion yuan in 2013, more than doubling year-on-year. The ratio of this value to the total public operating profit (not a percentage, because the report was not included in China Business profit) up to 36.8%. In the first half of this year, the ratio climbed to 42.4% and operating profit reached 2.622 billion euros, a year-on-year increase of 10.6%.
The QNP Steam Turbines` capacity mainly covers 200MW and below, include NI series (Normal Impulse Turbines) and HE series (High Efficiency Turbines). Our steam turbines are flexible and diverse in structure and layout so as to meet various requirement of our users. Aiming at the global leading equipment manufacturing enterprise, our design and R&D standards are higher than GB standard and in the same league with European and American energy equipment manufacturers.
1.Characteristics of QNP Turbine
QNP adopts advanced small pitch-circle technology in its high-end High Efficiency Turbine products, and hence considerably improved the turbines`flow efficiency.
By combining the advanced technology of European turbine with QNP technology, and optimizing the integration between imported advanced R&D tools and advanced domestic design software, QNP has solved the universal defect of inter-stage efficiency loss in most domestic units.
Using 3D bending-torsion blade design to improve the final and penultimate stage efficiency and structural strength to ensure long-time continuous operation of the unit.
Using high-speed running design and full-cycle steam distribution to improve the unit`s flow efficiency, reduce space occupancy, and make the installation more efficient.
Optimized enthalpy drop distribution design, through the comparison of tens of thousands of design data, form the best single-stage enthalpy drop distribution solution to ensure that each unit is in its maximum efficiency.
High-precision and high-quality manufacturing process: to ensure the high precision and high quality of key dynamic and static components, the flow passage components are processed by four-axis or five-axis CNC machining center.
Specially produced for high-end users, each component is carefully designed and the unit always presented to the customer as a flawless modern industrial artwork.
Maximum internal efficiency may reach 88%
2.Technical characteristics of parts
Gland sealing matching: the industry-leading and advanced gland sealing structure design reduces the steam leakage loss.
Blade assembling: the optimized blade molded lines are designed by the international advanced design software and processed by high-grade, high-precision and advanced technology which improve the thermal efficiency greatly.
Governing system: advanced governing methods are used for high control precision and fast response speed and which also has the electronic over-speed trip function, load shedding trip function, as well as auto start, grid connection and on-load function.
Rotor: we have shrink-on rotor and solid forging structure rotor which are all processed by Mitsubishi Planer machine and adjusted by vacuum high speed dynamic balancing machine to make sure the vibration of each position of bearing is in good state when the Steam Turbine running. Small vibration of the rotor we produced is a distinctive characteristic of our products.
Condenser: the stainless steel screwed pipe is used as heat exchanger with good anti- pollution ability and high heat-exchange efficiency. High-quality titanium tube is used when the cooling water is seawater. We use digital controlled lathe for drilling hole.
Casing: the split is processed by one-off molding technology and the precision of which can be 0.0058MM without any steam leakage. The concentric circles of the whole axis are processed by high precision turn-milling of the 5-joint axis machining center.
Diaphragm: we use qualitative carbon steel as the support and make the flow field better comply with the design via special welding technology so as to improve the internal efficiency.
Lubricating oil system: the multiple filtration technology--impurity strainer of oil tank, double bucket strainer for refined filtration, bearing inlet strainer which can be replaced during running--make the turbine oil entering the bearing bush achieve the best performance.
Control and protection system: QNP uses the Siemens microprocessor as the core of the system to ensure the stability and timeliness of signal processing. For important signal, multistage redundancy functions are introduced to ensure the safe and stable operation of equipment. Friendly interface makes operator work easily. More than 3-monthes` record of operating data can be saved by recording system and also can be extracted at any time.
3.Various layout and application
Except the general double-tier layout structure, we also developed steam turbine with single-tier and fast-installation layout structure, mainly includes:
(1)Oil tank as base plate:
The position of oil tank for Condensing Steam Turbine can be designed under the steam turbine as the base plate with the steam turbine, bearing pedestal and gear box on it which has same horizontal plane with condenser.
(2)Three platform and one station steam turbine:
Composed of steam turbine base plate, auxiliaries base plate, control base plate and centralized oil station for a convenient installation and layout at site. And the centralized pipeline will let the site more clean and tidy.
(3)Axial exhaust type
Mainly applied in 15-50MW condensing and pumping condensing high efficiency turbine. This type of steam turbine adopted single-tier arrangement, with axial exhaust directly into the condenser. Suitable for whole machine delivery, and can considerably shorten the installation period and reduce civil engineering costs.
