PSA OXYGEN CONCENTRATOR USING DC POWER SOURCE

摘要

PURPOSE: A pressure swing adsorption(PSA) oxygen generator for direct current(DC) is provided to stably self-generate pure oxygen in a transporting unit and to prevent the occurrence of an oxygen supplying stopping phenomenon by detecting the insufficient supply of electricity capacity. CONSTITUTION: An air compressor(2) drives the driving electricity of an air compressing unit based on the using voltage of DC12V to DC30V at 40A or less of capacity. The voltage value of used DC electricity is recognized by a voltage sensor(16). A first pressure sensor(5) detects the change of pressure values in an air pressure line before compressed air is introduced into an oxygen separating adsorption column. A second pressure sensor(14) detects the pressure value when the high purity oxygen from the oxygen separating adsorption column is adjusted using a pressure adjuster. An alarming unit generates an alarm by comparing the detected voltage values with a programmed value.
