USE OF RESONANCE SUPERCHARGE FOR INCREASE THE PRODUCTIVITY OF PISTON COMPRESSORS

Abstract

The perfection of piston compressors, especially of multistage compression, represents a rather urgent task. From the energy loss to compression of air, for example, substantially depends the efficiency of air separation plants of small and average productivity, which are created mainly on the basis of piston multistage compressors. In the given article, which has a review character, are considered the features of a way of increase the productivity of piston compressors at the expense of organization in them of resonant pressurization of air. The treatment of physical character of the processes making a basis of the given way of forced manufacture of compressed air is given. Is paid attention to necessity of application the electroanalog models and electromodeling for definition of own frequencies of soaking up highways of complex designs and schemes. Is shown that the growth of productivity in the air piston compressors can achieve 15% at simultaneous insignificant increase of power consumption at 3–6 %. The calculation of the basic design data of a soaking up highway ensuring resonant pressurization of the air piston compressor with four steps of compression is resulted. It is made the conclusion that the parameters, determined on existing techniques, can be considered as initial approximation. Their final updating should be carried out with the help of exacter techniques or on the basis of researches of experimental models of real soaking up highways of compressors. The introduction of the specified way will enable to improve both characteristic of compressors, and plants, in which they are used.
