Pressure Vessel design of the chemical industry that is a kind of mechanical design, in order to meet the needs of social life, the constant pressure vessel development and improvement. In order to production needs, the structure of the pressure vessel, the design of the way, bringing them in line with customer demand factory, the design of the following: First, pressure vessels of the board of the design; two, shell hole size, location of the design; 3 , Welding technology of choice. This paper reviews the new type of highly efficient heat exchangers at home and abroad in recent years for the Research, Design and in accordance with national standards of shell-and-a heat exchanger, found problems in the design and through, choose the right parts, on the basis of knowledge of Shell heat exchanger to improve the views, but also at home and abroad enhanced heat transfer components and a new highly efficient heat transfer technology direction of development were discussed. Key words:（关键词：） mechanical design, heat exchangers, heat transfer enhancement, head, flange, Baffled, the national standard希望我的翻译对你有帮助

兄弟，这么长，就出五分，你也太葛朗台了吧

Calculation of thermodynamic calculation is the basis of the compressor. General the calculation of the compressor in heat-aided design systems have a compressor to help would greatly speed up the design process so that a more rational design. Compressor lubricating oil and has no thermodynamic calculation, the calculation in manual access map errors, data are not consistent with the calculation of the selected request, the result of incorrect calculations or inaccurate. At present there is no response to any oil-lubricated compressor-assisted calculation system. By the calculation of the required number of charts, prepared without oil lubricated compressor Thermodynamics-aided design system, simplifies the success of any oil-lubricated compressor thermodynamic calculation process, the realization of the data required to calculate the line selection, Chaturvedi smart look-up table, the output of data, save and print, and to improve the accuracy of the calculation parameters and words thermal calculation compressor oil-free-aided design system希望能帮到你

The thermodynamic calculation is the basis of the compressor calculation. With the help of the compressor-aided design system, the ordinary compressor is able to speed up its progress in calculation, which in turn reasonablizes the design; while the thermodynamic calculation of non-oil lubrication compressor caused errors or inaccuracy when pictures are retrieved by hand and figures are not best chosen. It is towards this problem that the compressor-aided design system for the thermodynamic calculation of non-oil lubrication compressor is made by digitalizing all the pictures and figures. This system will simplize the calculating process of the thermodynamic non-oil lubrication compressor, enable to select data on line, retrieve pictures and figures intelligently, output, save and print them and improve the accuracy and reliability of the calculating parameters as words：compressor , thermodynamic calculation, aided design system, non-oil
