The Optimization Of Centrifugal Compressor's Operation

With its unique advantages and wide applications Centrifugal compressor is widely used in the petrochemical and chemical industries, the design efficiency of the compressor is constantly improving, and getting to a relatively high level, but when the compressor is put into the actual use, it can not be achieved in the design points by various reasons. That makes the operation of the unit not only unstable, but also caused a great waste of energy which is contrary to the national trend of energy saving. There exit the difference during the compressor from the design and manufacture to actual use; or when actual production process is changed, we have to change the import conditions; and different adjustment methods lead to different the effect of energy saving;so use the theory of similarity to do analysis and conversion, and combined with the current existing research on how to achieve optimal operation situation, and confirm the principle of methods such as:export, import regulation, imports of pre-spin regulation, variable speed control and other, and analysis of the advantages and disadvantages of each method by theirs operability, economy.
