Xichai production line As a state-owned enterprise, Xichai implemented the spirit of the 18th National Congress of the Communist Party of China, and built ecological civilization into a long-term plan that concerns the well-being of the people and the future of the nation. The factory abandoned the extensive development of the old road, with low carbon, energy saving, environmental protection as the responsibility and responsibility, build green factories, production of green products. According to statistics, since the first battle to defend the blue skies, Xichai has been able to display its total asset turnover rate, liquidity turnover rate, fixed asset turnover rate, profitability, profitability, and cost-benefit ratio. The industry first. From January to May this year, Xichai sold 135,000 diesel engines, an increase of 7.74% year-on-year, with a year-on-year growth of 95.89%. Among them, Aowei 6DM diesel engine sales volume was 55,000 units, an increase of 91.4% year-on-year, and the market share in the 11-liter power segment was more than 60%. This series of data shows that while building the ecological civilization, Xichai has maintained a sustained, steady and healthy development.
Build a green environment and build a low carbon plant
At the onset of World Environment Day on June 5, Xichai opened its doors to the nation’s news media and demonstrated Xichai’s dedication and symbiosis with society to share the vision of a green future.
It is understood that Xichai is currently the only manufacturing enterprise in Wuxi's downtown. In the past decade, Xichai has invested hundreds of millions of dollars in the most basic safety and environmental protection projects, and successively established sewage treatment stations, adding sound insulation, sound absorption, and Muffler facilities, added spray paint exhaust treatment adsorption system. Replaced coal-fired boilers with steam from thermal power plants, which reduced the total discharge of major pollutants by 57%, and exceeded the target of reducing the total discharge of major pollutants by 10% proposed by the national “Eleventh Five-Year Plan†outline; The transformation of the pipeline network has increased Xichai’s daily sewage treatment capacity from the original 2,700 cubic meters/day to 3,200 cubic meters/day. Now, Xichai has used recycled water (Zhongshui) in daily greening, cleaning and cooling. It is estimated that Xichai uses 400,000 tons of reclaimed water each year, which saves more than RMB 1 million in water charges in only one year.
Xichai production workshop
At the same time, in terms of low-carbon emission reduction, Xichai spent more than 10 million central air-conditioning systems built at the heavy-duty diesel engine production base in Huishan, using a ground-source heat pump compound system, a new type of heating and cooling that utilizes shallow surface energy on the Earth’s surface. Energy use technology has effectively reduced the consumption of various non-renewable energy sources....
Using green technology to develop green products
While creating green environment, Xichai innovatively uses high-tech means to develop green power and manufacture green products with green production processes.
The author understands that in product development, Xichai adopts the latest international technology in engine design, combustion system development, engine calibration, vehicle matching, and vehicle service in many aspects to reduce the energy consumption of the engine during use, enabling Xichai Engine The overall fuel economy during operation is 5-10% lower than that of competitors. Xichai strengthens the research of DPF technology. After 8 years of technical research, it has successfully developed the first domestic 4DW-E5 series of five diesel engines with DPF installed and commercialized, achieving the effect of purifying 90% of the particles of diesel exhaust. This technology has won 6 invention patents, 36 utility model patents and software copyrights. In addition to the full launch of the China Five Engine, Xichai also devotes itself to building the Sixth National Product Platform, considering the direction of future product development in terms of energy recovery, low-friction technology, intelligent vehicle driving, and improved combustion efficiency. Close to "zero pollution" engine.
Not only that, Xichai uses a large number of green technologies to produce green products. Enterprises will be green manufacturing throughout all aspects of production. In production equipment, Xichai has become the first company in China to use AC power dynamometer technology in heavy-duty diesel school bus production lines. Xichai uses AC power dynamometer technology to convert the energy output from the engine's flywheel end to AC power. It can effectively absorb more than 90% of the engine's output energy and return it to the grid, significantly reducing water and electricity consumption. In the production process, Xichai is the first domestic company to introduce and apply cold test technology for heavy-duty diesel engine production lines. Compared with the traditional hot test technology, the cold test process technology can greatly reduce the product delivery cycle while allowing the school bus to no longer consume diesel fuel, and does not require a large amount of water, electricity, gas supply, and even no exhaust emissions. Low-carbon and environmentally friendly production. By the end of 2016, the proportion of cold test products shipped from Xichai was more than 90% (without long oil change models), which saved a total of approximately 2,500 tons of diesel fuel. The cold test process research results have also won the second prize of the China Machinery Science and Technology Award and the third prize of the China Automotive Industry Science and Technology Award.
Development of recycling economy remanufacturing turning waste into treasure
Xichai has always organically combined green energy conservation with the concept of “independent innovation and leading the market†and penetrated it throughout the product life cycle. "Give me the old machine and give you a brand-new remanufactured engine. The performance is exactly the same as the Three Guarantees policy and the new machine!" This sentence is not only a commitment to the customer, but also a continuous excavation of the Xichai remanufacturing base. The ability of domestic demand potential is a manifestation of strength. It is reported that at present, Xichai has reached the industry-leading level in engine remanufacturing technology, electronically controlled injector remanufacturing, gas system remanufacturing, post-processing remanufacturing and other technologies. Since its official production in 2011, Xichai remanufacturing base has Cumulative sales of more than 5,000 remanufactured engines, and more than 30,000 injectors were manufactured, with sales exceeding 100 million yuan.
According to the person in charge of the Xichai remanufacturing base, the remanufacturing of Xichai engine is different from the recycling of waste materials, and raw materials or components have been reborn. Remanufactured cores are manufactured using the manufacturing model, which is a high-tech repair technique, and it is an industrialized repair. Therefore, remanufacturing is an advanced stage of maintenance and development, and it is a kind of traditional maintenance concept. Promote and rewrite. Compared with newly-manufactured products, Xichai remanufactured engines can save 60% in production, save 70% of materials, save material costs by 50%, and reduce air pollutant emissions by 80 percent compared to the same period in terms of ensuring the same quality and performance. %the above. Xichai passed the assessment of the National Development and Reform Commission in 2012 and became one of the first batch of four engine remanufacturing pilot units that passed acceptance in China. In the following five years, it has truly created a new model of circular economy development of "resource-product-waste-reuse".
Xichai used practical actions to interpret the political responsibilities, economic responsibilities, and social responsibilities of the state-owned enterprises to the whole society. It reflects Xichai's determination to join forces with society and share a green future.
Since the growth of sugarcane has certain requirements on plant spacing, row spacing and planting depth, it requires a lot of manpower and time, but one machine can bear the workload of several or even dozens or even hundreds of people. Compared with manual production, using machinery for production can complete more work in a shorter time, greatly save the time required for each link of sugarcane manufacturing, and reduce the cost consumption in the sugarcane manufacturing process.
The Self-propelled automatic sugarcane harvester specially developed by TAGRM can automatically cutting the sugarcane and even fallen, which greatly accelerates the efficiency of sugarcane harvesting.
