The digital-control-generation equipment innovation project is the promotion and application of digital control technology on various types of equipment, integrating and innovating a number of numerical control equipment, realizing the upgrading of equipment performance and functions, and thus promoting the transformation and upgrading of the equipment manufacturing industry. As early as the beginning of 2011, the 8 academicians put forward suggestions on the implementation of the "CNC-Generation of Mechanical Products Innovation Application Demonstration Project", which was highly valued by the relevant national authorities. In the first half of 2012, the “CNC Machine Product Innovation Application Demonstration Project†was released and implemented. In this context, the "CNC Generation Equipment Innovation Project Action Plan" was soon released. The development of the digital control equipment manufacturing industry is clearly visible. The "plan" shows that in order to achieve the goal, it will focus on organizing and implementing five major actions: the development of digital technology development and promotion service platform, the development and industrialization of numerical control technology, the integration and innovation of numerical control equipment, the demonstration and promotion of numerical control equipment, and the construction of numerical control equipment specifications and standards. . Among them, PLC, man-machine interface, control software, frequency converters, servo drives, energy-saving motors, and other automation technologies are regarded as key development targets, and will enjoy the policy of rain.
Among them, first we must further improve the quality and reliability of products such as general-purpose programmable controllers, human-machine interface devices, integrated controllers, and software packages.
Secondly, it is necessary to strengthen the development of professional application software and hardware combined with the manufacturing process of typical industries to meet the needs of the development of the industry's numerical control equipment.
Focus on the development of a variety of numerical control devices required for servo drives and motors, such as digital servo control systems, network distributed servo systems and other servo drives, energy-saving motors and variable frequency motors.
Focus on the development of high-power, high-performance variable frequency speed control system, traction with the frequency control device and special speed control with the frequency control device.
Focus on textile machinery, plastics and rubber processing machinery, small and medium-sized machine tools and basic manufacturing equipment, printing machinery, packaging machinery, food processing machinery, pharmaceutical machinery, energy-efficient products, etc., to achieve numerical control integrated development.
The numerical control of equipment has become an important development trend. Industrial advanced countries attach great importance to the development of high-tech equipment. After more than ten years of development in China's equipment manufacturing industry, the proportion of numerical control equipment in the domestic market has continuously increased, and strong innovation capabilities have emerged. More solid foundation. The issuance and implementation of the "plan" will further promote the digitalization of equipment. Luo Baihui said that China's equipment manufacturing can achieve a typical industry of mold manufacturing, metal processing and other equipment in 2020, the numerical control rate of equipment reached 70%. The development of digital equipment development and promotion service capabilities have been significantly enhanced, and continuous training of large numbers of CNC equipment can be operated and Maintenance of skilled personnel. Achieve wide application of numerical control equipment, and increase the production efficiency by more than 20% in key application areas, and reduce energy and resource consumption by more than 30%.
Chemical fertilizers, referred to as fertilizers. Fertilizers made by chemical and (or) physical methods containing nutrients needed for the growth of one or more crops. Also known as inorganic fertilizers, including nitrogen fertilizers, phosphate fertilizers, potassium fertilizers, micro fertilizers, compound fertilizers, etc., can not be eaten.
They have some common characteristics: simple composition, high nutrient content; Fast fat efficiency, fat vigorous; Some fertilizers have acid-base reactions; Generally does not contain organic matter, no role in soil modification and fertilizer. There are many types of chemical fertilizers, and the properties and application methods vary greatly.
Fertilizers that contain only one nutrient content can be called unit fertilizers, such as nitrogen fertilizers, phosphate fertilizers, potassium fertilizers, and secondary macronumeric and trace element fertilizers. Fertilizers that contain two or three of the three nutrients of nitrogen, phosphorus and potassium and can indicate their content are called compound fertilizers or mixed fertilizers. The solubility of the effective components of a fertilizer in water is usually a measure of the effectiveness of a fertilizer. Grade is the main indicator of fertilizer quality, it refers to the percentage of effective nutrients or their oxides in fertilizer products, such as: nitrogen, phosphorus, potassium, calcium, sodium, manganese, sulfur, boron, copper, iron, molybdenum, zinc.
Phosphate fertilizer, Nitrogen Fertilizer and potassium fertilizer are chemical fertilizers with large plant demand.
