GASDYNAMIC RESONANCE PHENOMENONS SUCTION SYSTEM AND THEIR USE FOR IMPROVEMENT EFFICIENCY OF AIR RECIPROCATING COMPRESSORS. 1. RELATIVE PERFORMANCES RESONANCE INTENSIFICATION

Abstract

Effective method of intensifying of piston compressors is the resonant oscillations use of gas pressure at the suction systems, as a set of the suction pipe, suction valve and cylinder as an acoustic tank with variable volume. As a result, it is possible to achieve better improvement efficiency of compressors to 20% with no capital expenditures by modernizing the suction system. The especially profitably use of resonant oscillations of gas pressure in the suction systems of compressors with double acting cylinders. The character gasdynamic wave processes in the suction system of compressor with cylinders of double acting is considered, influencing the process of filling a gas cylinder in three specific areas of the suction system. At first, the suction system is divided on three zones: below resonance, resonance and above resonance, in which a cylinder air filling is different. The compressor relative performances subject to the resonant intensification are introduced, the analysis indicator diagram. The substance of the resonant acoustic intensification piston compressor is ascertained, which reflects the combined influence of suction valves of resistance and wave processes in the resonance conditions.
