COMPRESSOR APPARATUS WITH A SINGLE COMPRESSOR CAPABLE OF RECOMPRESSING COMPRESSED FLUID FOR DISCHARGING FLUID AT DIFFERENT PRESSURE

摘要

PURPOSE: A compression system with a single compressor for recompressing compressed fluid to discharge fluid with different pressure is provided to enlarge the application range of the compressor by discharging fluid at different pressure with the single compressor. CONSTITUTION: A compression system has a compressor(100) having an intake pipe(102) and a discharge pipe(103), plural branch pipes(104) extended from the discharge pipe and communicated with fluid, and plural chambers(131,231,331,431,531,631) communicated with the branch pipe. Each chamber is communicated with the intake pipe through a return pipe unit(20), and plural pressure sensors(141,241) are placed in chambers to set each discharge pressure. Fluid flows from the chamber through the return pipe unit into the intake pipe when hydraulic pressure of the chamber reaches the discharge pressure. A control unit(7) is installed in the branch pipe and the return pipe unit, and controlled by control valve units(121,211,232). The fluid is moved through chambers according to the order of increasing the discharge pressure.
