Weichai Power will match the excavator with "Chinese Heart"
After the tireless efforts of Weichai's technical system and marketing system, the blue-green power that was specially created for the excavator, WP5 and WP7, will soon enter the construction machinery market. The situation where the heart of the excavator is completely dependent on imports will be broken by Weichai Power.
In recent years, the domestic excavator market has developed rapidly. In the first quarter of 2010, the excavator market showed a unique "Chinese style leap forward," and sales figures continued to climb. The hot sales boom has hidden concerns, because all foreign military units are based on completely occupying the supporting market of Chinese excavator products. Weichai, the first player in the loader market, has made unremitting efforts to this end. The Lanqing series "WP5, WP7" - the "Chinese heart" of the excavator was finally born, and will soon support the large-scale supply of excavators in China.
Weichai Power has successfully developed a WP7 excavator engine
As the largest auto parts enterprise group in China, the matching rate of Weichai engines in the domestic loader market is as high as 80%, and the matching rate of cranes has also reached 40%. As the superior product of Weichai Power, the WD10 loader engine has been the world's leading power loader.
With the successful development of the WP5 and WP7 excavator engines, coupled with the introduction of technology to the Italian VM engine company at the end of 2009, Weichai Power has the ability to cover a full range of 2-15L engines. Can use VM engine supporting 6-13T mini excavator, WP5 engine supporting 13-21T medium and small excavators, WP7 engine supporting 21-45T large and medium-sized large excavators, 45T or more large excavators and Weichai original With more than 10L engine series, the entire product line of Weichai excavator power has been fully constructed.
During the five years from 2005 to 2010, many vehicles participated in the experiment. The total time of experimentation and the number of kilometers tested in the vehicle were much higher than the European standards. As a product of Weichai's craftsmanship, the WP5 and WP7 engines have unique advantages in terms of technology, quality, reliability, and adaptability. It is embodied in its high reliability, low fuel consumption, light weight and low noise. In the research and development process, Weichai has adopted advanced structures. From the demonstration of plans to the analysis of reliability, each design process has been recognized by European experts. The product adopts a high-intensity jointed cylinder block and a high-strength crankshaft. In strict accordance with the most advanced experimental standards in Europe, the gantry reliability and endurance tests have been accumulated for over 8,000 hours, and the overall operating life of the diesel engine has exceeded 2 million kilometers. In order to reduce fuel consumption and improve efficiency, WP5 and WP7 adopt Bosch's new-generation high-pressure common-rail pump, which is smaller in size and higher in oil pressure. It is equipped with a bleed valve supercharger, and the oil consumption creates a new indicator for the same displacement model. Point 209 g/kW.h, combined fuel consumption 206 g/kW.h. The gantry body, the integrated cylinder head and the wet cylinder liner of these two models all passed the advanced CAE finite element analysis, utilizing the high-strength arc surface design and vertical and horizontal stiffener arrangement, which greatly reduced the overall quality. Bosch's new-generation common-rail oil pump and common-rail tube make the weight reduced. At the same time, the gear chamber and the flywheel housing are combined to reduce the cast iron material. Therefore, the overall machine quality is only 620kg, which is the lightest in domestic engines with the same displacement, and the ratio of the WP10 engine. 250kg reduction in quality. At the same time, the high-intensity design of the body ensures the minimum vibration of the whole machine; with the rear-mounted gear tooth system, the heightened tooth shape design makes the operation more stable and the noise is lower.
In addition, at the stage of research and development of WP5 and WP7, Weichai has made certain improvements in the use conditions of excavators, and has carried out adaptive development in light of the quality of China's oil products, a vast territory, and large differences in working conditions. The environment has personalized engine design.
Although the competition is fierce, there is a unique advantage in Weichai's competition with foreign engine brands. As a domestic brand, Weichai has the advantages of adaptability that cannot be matched by foreign brands. It also understands the needs of the Chinese customer base, and can analyze and improve products in a timely manner. It will never present the symptoms of "unsatisfied with water and soil" that foreign products enter and exit into the Chinese market. At the same time, we have innate advantages in humanized services and professional services to customers.
It is understood that by the end of this year, Weichai Power's WP5 and WP7 excavator engines will be put into the Chinese market in large quantities. By then, the China’s largest excavator market will be equipped with the “Chinese Heart†via an excavator. This is another debut of the domestic engine, but also a qualitative leap in the localization of Chinese power.
