In recent years , with the PCB vigorous development of coal chemical industry, with the support of large-scale air separation equipment market has also ushered in tremendous opportunities and challenges. Although China since 1953 developed the first set of 50m3 / h air separation plant has been nearly 60 years of history, but with the international ASU hundred years of history , both in the domestic level technical or equipment on the there are some gaps , particularly from the lack of core technology . Thus, the domestic enterprises to reduce the gap , PCB but also an urgent need to take appropriate measures in line with China 's national conditions , while the electronic copy board PCB industry "dark horse" , through the introduction of technology absorption and innovation , will be the fastest speed to make up the core technology of Shame .
Opportunities for development of large-scale air separation plant PCB
In the second session of the coal chemical technology supporting large-scale air separation plant in exchange meeting, China General Machinery Industry Association Branch Secretary Xu Jianping gas separation equipment , "said the large-scale development of coal chemical industry , requires supporting ASU must implement large-scale PCB, process diversification and integration unit if reported 104 coal chemical projects and energy Bureau of the NDRC approved all , only 100,000 level of demand for air separation plants in a hundred . "
Opportunity to promote PCB copy board to break the storm
Faced with such opportunities , China's space division to PCB larger enterprises to speed up the pace of air separation equipment to enter , but it is also a challenge to not have the international advanced level of independent research and development of domestic enterprises, and for PCB copy board companies need not scruple it all. Because the study by means of a reverse PCB copy board , you can quickly break through advanced ASU core technical barriers, and 1:1 reduction products PCB files , Bom list , schematics and other full technical information is then used to copy clones and two time to develop .
Challenges faced by large-scale air separation plant
In addition, the domestic large-scale air separation plant apparent " gas shortage " does not mean a single ASU lack of core technology, but also in ASU enterprises lack the capacity to break through in terms of equipment , technology, complete sets of capabilities. Such as: First, large sets of air separation equipment for the Ministry of the key core rotating machines, due to the lack of independent technology failed to achieve synchronization of large-scale and large PCB, large air compressor , booster , high efficiency medium-pressure expander , liquid The key components of the expander , large centrifugal pumps for liquids , etc. is also largely dependent on imports . Second, supporting industry chain is not perfect . Development of gas separation equipment specifically required for the design, manufacturing and other ancillary services system is not yet formed the industrial chain , especially in the development of large, extra large air separation equipment , missing many important aspects , resulting in only resort to imports, complete sets of domestic equipment difficult to achieve. Third, compared with foreign products , domestic equipment manufacturing process and meticulous management is not enough, the overall design , structural design, piping and other rough, the level PCB of quality and reliability is not high , resulting in increased operation and maintenance costs , domestic users is difficult to establish lasting trust.
