On the status quo and research significance of Pump equipment manufacturing industry in China:
Pump equipment manufacturing industry is one of the largest industrial categories in China, which consumes more energy, raw materials and pollutants in its own production process. In the equipment manufacturing industry, casting, forging, electric transfer, heat treatment and other thermal processing processes consume the most energy and produce the most pollutants, among which gear oil pump accounts for about 60% to 80% of the equipment manufacturing industry. For example, the average energy consumption of casting industry is about 0.55-0.7t standard coal per ton of casting production, and 0.3-0.4T standard coal abroad. The average consumption of forgings per ton in the forging industry is about 1.4 tons of standard coal, while the energy consumption of forgings in Japan is only 0.515 tons of standard coal. Heat treatment industry average energy consumption per ton of workpiece heat treatment 660Kw.h, developed countries average energy consumption below 450KW.h, the same one ton of cast iron can produce 5-30 stainless steel pumps of different sizes, therefore, China's energy conservation and emission reduction work potential is great.
There are two different choices in the future of China's pump equipment manufacturing industry: if we continue to follow the original extensive growth of the extension of reproduction mode, China will undoubtedly pay a higher cost of resources and environment while getting faster economic growth; On the contrary, if the circular economic development mode is adopted, it is possible to achieve faster economic growth with less cost of resources and environment. Therefore, the development of circular economy to achieve the pump equipment manufacturing industry growth mode change research, is conducive to theoretically improve the understanding, to achieve the equipment manufacturing industry development and ecological environment harmonious unity. It has become an urgent need to develop the equipment manufacturing industry to change the growth mode and improve the sustainable development ability. As a big economic country in short of resources, we should understand the far-reaching significance of developing circular economy in China's equipment manufacturing industry from an overall and strategic height, vigorously promote the development of circular economy in equipment manufacturing industry, and put the scientific concept of development into practice.
Significance of the study
Circular economy is a new trend of world economic development, a new model to solve the problem of sustainable development, and an inevitable choice of China's economic and social development strategy in the 21st century. Circular economy fully embodies the requirements of the scientific concept of development, is an important carrier of new industrialization, and is also an effective way to change the mode of economic growth and establish a resource-saving and environment-friendly society. Equipment manufacturing is the leading industry in the process of industrialization, and the development of circular economy is the fundamental driving force to build advanced equipment manufacturing base. Since the reform and opening up, China's equipment manufacturing industry has developed rapidly and made great achievements. However, so far, the growth mode of equipment manufacturing industry is still based on extensive quantitative expansion. While the output value increases rapidly, it consumes a lot of resources, faces the constraints of increasingly tight resources, and also causes great damage to the ecological environment. Therefore, it has become an urgent need for the development of China's equipment manufacturing industry to vigorously develop circular economy, effectively change the growth mode of equipment manufacturing industry, realize the harmony and unity between the development of equipment manufacturing industry and the ecological environment, and improve the ability of sustainable development. The development of circular economy is the objective requirement of the reform of the growth mode of pump equipment manufacturing industry, the internal power of industrial technology upgrading and industrial structure adjustment, the premise of equipment manufacturing industry getting rid of the restriction of resource bottleneck, and the effective way of China's equipment manufacturing industry to actively respond to environmental barriers and enhance international competitiveness. Therefore, under the background of "two-oriented society", it is of strategic significance for equipment manufacturing industry to develop circular economy.
