Today, with global resources and energy shortages, “remanufacturing†is undoubtedly an effective way of energy conservation and environmental protection. FAW Group, as the first batch of auto parts remanufacturing pilot enterprises established by the National Development and Reform Commission in 2008, is even more remarkable in terms of remanufacturing, in order to explore the mysteries of FAW Xichai 's second life given to the heart of the car. Recently, the reporter walked into the Xichai engine remanufacturing base of the FAW Group in the beautiful Wuxi New District. “The remanufacturing process of Xichai Engine fully demonstrates the superiority of remanufactured products both in terms of energy saving and environmental protection, and recycling of resources.†Before the modern multi-functional stereoscopic warehouse of Xichai Engine Remanufacturing Base, the reporter saw it here. Three-story three-dimensional warehouses have been neatly filled with old machines. These old engines are used as "blanks," and high-tech cleaning and repair technologies are used to remanufacture old machines. The main technical performance and quality can meet the same standards as new products. Claim. “Remanufacturing is in fact a high-level form of recycling economy. Xichai engine remanufacturing technology is specifically divided into parts dismantling, cleaning, classification, testing, repair of failed parts, remanufacturing machinery processing, reassembly, and factory inspection. Link.†The person in charge of the base told the reporter that at present, the Xichai remanufacturing base has four work areas, namely, a dismantling workshop, a surface repair workshop, a machining workshop, and an assembly workshop. The dismantling plant is not only equipped with mature remanufactured equipment for Europe and the United States, but also has introduced high-temperature, water-jet cleaning technology from the United States and Canada. It is understood that the high-temperature and high-pressure water jet cleaning machine is used to clean the appearance of the old engine into the workshop, providing a clean and tidy environment for the dismantling work. The disassembled parts enter the pyrolysis cleaning system where they are subjected to thermal cleaning, water cleaning, and vibration cleaning. The stubborn grease on the inner and outer surfaces of the parts is thoroughly cleaned. The person in charge of the base told the reporter that the cleaning process here complies with the requirements of environmental protection and does not emit any harmful dirt. Air emissions have reached European standards. "Xichai engine remanufacturing technology follows the three principles of reducing, reusing, and recycling of circular economy." In the surface repair shop, the person in charge of the base told reporters that "surface repair is the integration of mature "surface engineering" technology. In the remanufacturing technology, the high-tech transformation of the used products will be implemented to achieve high quality, high efficiency, energy saving, material saving, and environmental protection." Looking around, the equipment here is very special. Some are closed devices such as several globes, and some are digital electronic devices with branch hooks. According to the basic introduction, the application of surface hardening technology such as high-speed arc spraying, nano-brush plating, and technology has ensured that the remanufactured products are not inferior to the new ones. The remanufactured coating and repair technologies have already broken through the “as isâ€. The limitations, using digital embedded technology, laser processing technology to upgrade, make remanufacturing technology a step. "The main parts such as the cylinder block, cylinder head and crankshaft need to be remanufactured. The manufacturing quality is the same as that of the new machine." During the visit to the machining workshop, the person in charge said that a number of numerical control processing lines were introduced here. The remanufacturing machining of parts such as cylinder blocks, cylinder heads, crankshafts, etc., enables them to meet the technical quality standards for new parts. He pointed to these devices and said that the repair of the connecting rod must go through the process of grinding the big hole, boring the small hole, grinding the connecting rod to separate the surface, and cleaning the finished parts. For the repair of the main bearing bore of the cylinder, the horizontal honing process is required to ensure the precision and technical standards such as the straightness and roundness of the hole. "The repaired parts are assembled and machine tested, and the main performance must meet the new engine standards before they are allowed to leave the factory." Xichai engine remanufacturing and remanufacturing processing has now reached the old age as new, and its power, economy and warranty have reached the same standards as the new machine. The entire process uses the most advanced computer ERP software management system to implement scientific and modern management of the entire remanufacturing process. It can be said that the entire system is environmentally friendly and efficient. The international leader and the domestic first are the goals of FAW Group's remanufacturing project construction. As Xichai's remanufacturing technology advances, the remanufactured engine not only can achieve new product quality, but also exceeds new product performance, saves 70% of materials, saves energy by more than 60%, and saves costs by 50%. It generates almost no solid waste and air pollution. Emissions are reduced by more than 80%, and the remanufactured engine is only about 70% of new products.
