ABB smart power technology shines "Power World"
ABB continues to promote local R & D and innovation, and advocates creating a better life with green and efficient smart power technology BEIJING, November 26, 2014 - At the second ABB Power World today, ABB, the world's leading power and automation technology group, with its theme of "Green Power, Better Lives," delivers a rich portfolio of products and systems Exhibitions and more than 60 technical seminars showcasing ABB's leading technologies in digital power generation, UHVDC power transmission, smart substation, smart power distribution and other fields, as well as applications in the petrochemical, semiconductor, non-ferrous metals, light industry, railways, commercial buildings and data Center and other industries, power solutions, highlight ABB's research and development in the field of power and in the field of intelligent technology leadership. After more than 30 years of rapid economic development, the Chinese economy has now faced with tremendous pressure on resources, environment and sustainable development. In response, our government is trying hard to achieve the environmental, economic and social sustainable development through economic restructuring, industrial upgrading and energy restructuring. Green, efficient smart technology is an important enabler for achieving these long-term goals. ABB Group Chief Executive Officer Shibu Fu said: "ABB through smart technologies and solutions to help customers in power and industrial, transportation and infrastructure efficiency and industrial restructuring and upgrading, our 'new phase' strategy and China We are very pleased that we can help China to reduce the impact of energy consumption and greenhouse gas emissions on economic growth. In the power industry, ABB has a wide range of industries including clean energy grid, UHV power transmission, distributed generation, smart substation and electric Car charging and other comprehensive smart power technology, can help the entire power energy chain to achieve efficient and reliable operation. " Faced with the current situation of unequal energy distribution in eastern and western China, HVDC technology with long transmission distance, large capacity and low loss provides the key solution. In the 1950s, ABB took the lead in commercializing HVDC technology globally and continuously promoted the improvement and development of this technology. In China, ABB has participated in the construction of 19 projects in 27 HVDC transmission projects including Xiangjiaba - Shanghai, Hami - Zhengzhou, Xiluodu - Zhexi and other routes, providing the core products and technical support for the construction of China's power grid . Extrusion Conical Twin Screw Barrel
Twin screw extrusion
Simply described, the twin-screw extruder is a machine consisting of two co-penetrating and self-cleaning identical screws which are mounted on shafts and rotate in the same direction in a fixed closed housing called [barrel" . The twin-screw extruders operate continuously with very short residence times.
The diameter of the screws in the conical twin-screw extruder is larger at the feed end and smaller at the die end.

The parallel twin screw and the conical twin screw
According to whether the screw axis is parallel or not, the twin screws can be divided into the conical twin screw and the parallel twin screw, where the parallel twin screws are divided into fully intermeshing type, partly intermeshing type, non-engaged type, etc. In the case of parallel screws, the feed end and the die end have the same diameter.
