"The internal combustion engine is not only a large consumer of energy, but also the most potential product for energy saving and emission reduction. In my opinion, to grasp China's internal combustion engine industry is to seize the energy-saving emission reduction." As early as in the two sessions a few years ago, the national Chairman of the National People's Congress, chairman of the China Internal Combustion Engine Industry Association and chairman of Weichai Holding Group Tan Xuguang made the above proposal. "Green Power, International Weichai" is not only the Weichai Group's dedication to its own years of development, but also a commitment and practice of national and social responsibility. Over the years, Weichai Group has promoted the transformation and upgrading of its development strategy and constantly optimized its internal industrial structure. Through independent innovation and technological R&D, development of circular economy, and green manufacturing, Weichai Group has achieved sustainable development, energy conservation, and emission reduction. While promoting its own development, it has set an example for improving the overall energy-saving level of the internal combustion engine industry and the international competitiveness of internal combustion engine products, and promoting the green development, cyclic development, and low-carbon development of the internal combustion engine industry. Adjust the structure to promote development and create green products The internal combustion engine is the dominant power equipment for transportation, construction machinery, agricultural machinery, fishing vessels, and defense equipment. The internal combustion engine industry is an important basic industry. After years of development, China's internal combustion engine industry has made considerable progress. According to statistics from the China Internal Combustion Engine Industry Association, in 2011, the output of internal combustion engines in China exceeded 77 million units and the total power was over 1.4 billion kilowatts. Throughout the "Eleventh Five-Year Plan" period, the annual output of internal combustion engines has increased by about 10%. In 2012, the total output value, total output and total power of the internal combustion engine industry were basically the same as in 2011. China has already become a global giant in the production and use of internal combustion engines. However, compared with the international advanced level, China's internal combustion engine products still have large gaps in energy conservation and environmental protection indicators. The key core technologies are lacking, and high energy consumption, high emission, and low performance internal combustion engine products are still widely used. The use of such restrictions restricts the further development of the internal combustion engine industry, and these problems are precisely the potential for the development of the industry. The development of the Weichai engine segment also has the same painful period as the development of the industry. As the pillar business of the company, Weichai engines are sold at home and abroad, but at the same time as production and sales increase substantially, the types of products are relatively single and the market concentration is high. This conceals risks and is not conducive to broadening the long-term development space of this sector. To this end, we have expanded our product lines, formed a comprehensive technology, covered the full-power range, and diversified market layouts. We have become the world's leading full-range, full-field power supplier and have become the goal of Weichai's engine business structure adjustment. Since 1998, Weichai Group, a traditional state-owned enterprise, has carried out all-round and systematic innovation in the areas of operation system, business model, technology research and development, and internal management, and has embarked on an intrinsic development path relying on independent innovation. Through the transformation and upgrading of development strategies and independent innovation, Weichai has now developed into a full-series, all-round manufacturing group with four business segments including complete vehicles, powertrains, auto parts, and luxury yachts. This is not only for the development of enterprises. The new market has also driven the pace of energy conservation and emission reduction of enterprises and the development of a recycling economy. As the only powertrain provider in China, after the system is optimized and matched, the vehicle development efficiency of the assembled Weichai powertrain is increased by 30%, and the fuel consumption is reduced by 10-15%. At the same time, the R&D team of Weichai Qianren and the R&D structure of “five countries and ten places†lay a good technical foundation for “adjusting structure and promoting developmentâ€, allowing enterprises to master core technologies while developing energy-saving emission reduction and recycling. The economy provides a reliable guarantee. As early as during the “Eleventh Five-Year Plan†period, Weichai took the lead in successfully developing a high-power, high-speed diesel engine that meets State III, State IV, and National V emission standards and has completely independent intellectual property rights. Its main technical indicators are in line with international advanced standards. Among them, the Blue-Rising III engine, which is currently supplied in large quantities in the market, is more than 15% more fuel-efficient than similar domestic products. According to industry association statistics, the use of Weichai engines can achieve annual fuel savings of more than 4,800 liters per year when each commercial vehicle is operating 100,000 kilometers. If calculated by one million vehicles, it can save nearly 5 million tons of diesel a year. At Weichai Technology Week, the highlight of 2013 Weichai Business Conference, Weichai focused on 51 new technologies and R&D achievements such as the application of new technologies, post-processing technologies, self-developed electronic control technologies, and bulldozer hybrid power. While effectively improving overall machine performance, it also made important contributions to energy conservation and emission reduction. Among them, the application of new technologies for combustion development has enabled carbon emissions to decrease by 45.83%, nitrogen oxide emissions by 4.6%, and fuel consumption. Weichai has been dedicated to the research and development of alternative fuel internal combustion engine products. Weichai LNG (liquefied natural gas) power has been widely used in long-distance passenger cars, wide-body dump trucks, heavy trucks and construction machinery. Responsibility for heavy cycle, development of green production Industry is a major consumer of natural resources and an important factor affecting the ecological environment. In particular, the characteristics of the internal combustion engine industry and the characteristics of the internal combustion engine products determine the main roles of the internal combustion engine industry in the process of independent innovation, energy conservation and emission reduction, and green manufacturing. As the most direct energy-saving and emission-reducing effect in the whole society and the greatest potential for energy-saving emission reduction, it is also an intermediate product of automobiles, construction machinery, agricultural machinery, ships, diesel locomotives, generator sets, etc. The entire internal combustion engine industry bears heavy Energy conservation and emission reduction social responsibility. In addition to transforming the development mode, accelerating industrial restructuring, and improving the capability of independent innovation to support the transformation and upgrading of the internal combustion engine industry, internal combustion engine companies should also pay attention to energy-saving materials and internal-combustion engine production to achieve green production. In recent years, Weichai has actively developed green production, and at the same time manufacturing green energy-saving products, it also pays attention to the green energy-saving of the manufacturing process, and has truly implemented the “green green firewoodâ€. Taking the recycling of industrial waste water, Weichai has a wastewater recyclable system with a daily treatment capacity of 4,400 tons in the old plant area. All industrial waste water enters the sewage treatment station and realizes a “closed-circuit cycleâ€. The system recycles more than 100 years of waste oil. Tons, annual reduction of 1.2 million tons of industrial wastewater discharge, annual water reuse of more than 1.5 million tons, and annual water saving of 1.5 million tons. In the industrial park, a wastewater recycling and reuse system with a daily processing capacity of 1,000 tons was built. The advanced technology of pretreatment of the quality and reintegration treatment was used, and 360,000 tons of reclaimed water and 360,000 tons of fresh water were recycled annually. After being treated and reused by the enterprise, Zhongshui is widely used in the production and life of trial-cycle water, production process water, toilet flush water, and fire-fighting water for large-series diesel engines, which reduces fresh water consumption and improves the environment. Reduced pollution. It is understood that Weichai has established four new industrial parks in Weifang and covers an area of ​​nearly 3,000 mu. The new project's energy-saving and emission-reduction infrastructure has been valued. Taking the new foundry industrial park as an example, the low-energy and energy-saving production facilities are fully selected in the process design, and the waste heat utilization technology is adopted. The high-temperature flue gas waste heat utilization system and steam condensate recovery system are installed in the cupola to implement waste heat and residual energy. Recycling, effectively reducing the park's heating steam and natural gas consumption. Among them, 80 tons of hot air oxygen-enriched cupolas, castings with an overall scrap rate of 1.8% or less, 220 tons of coke per ton of castings, 47,000 tons of coke per year than the domestic average, and secondary combustion of flue gas through waste heat utilization technology. The temperature of molten iron reached 1500-1550°C, and the melting efficiency increased by 45%. The recycling rate of waste sand was over 85% through the old sand recycling technology. With the technology of fully-sealed bag dust removal, the dust removal rate reached 99.8%. In the processing industrial park, Weichai has attached great importance to the basic construction of energy-saving and emission-reduction and adopted low-energy-consumption and energy-saving equipment to ensure that the energy use of the new park is optimal. Eliminating outdated, high-energy-consuming technologies and equipment, actively implementing energy-saving technological reforms, and paying attention to the new project's energy-saving and emission-reduction infrastructure are all means by which Weichai strengthens self-discipline and realizes green production. With the increase of environmental awareness among the public and the importance attached to ecological environmental protection by the country, the internal combustion engine industry bears a major responsibility for the harmonious development of the industry economy and ecology. As the leading enterprise in the internal combustion engine industry in China, Weichai is practicing practical and effective actions. With the promise of green and sustainable development, we will continue to fulfill our due obligations to build “beautiful Chinaâ€!
Pneumatic cylinders (sometimes known as air cylinders) are mechanical devices which use the power of compressed gas to produce a force in a reciprocating linear motion.
Like hydraulic cylinders, something forces a piston to move in the desired direction. The piston is a disc or cylinder, and the piston rod transfers the force it develops to the object to be moved. Engineers sometimes prefer to use pneumatics because they are quieter, cleaner, and do not require large amounts of space for fluid storage.
Because the operating fluid is a gas, leakage from a Pneumatic Cylinder will not drip out and contaminate the surroundings, making pneumatics more desirable where cleanliness is a requirement. For example, in the mechanical puppets of the Disney Tiki Room, pneumatics are used to prevent fluid from dripping onto people below the puppets.
Once actuated, compressed air enters into the tube at one end of the piston and, hence, imparts force on the piston. Consequently, the piston becomes displaced (moved) by the compressed air expanding in an attempt to reach atmospheric pressure.
Although pneumatic cylinders will vary in appearance, size and function, they generally fall into one of the specific categories shown below. However there are also numerous other types of pneumatic cylinder available, many of which are designed to fulfill specific and specialized functions.
