PURGE CONTROL METHOD OF AIR TANK

摘要

PROBLEM TO BE SOLVED: To provide a purge control method of an air tank for optimizing purge collection in the air tank and detecting a time when performance of a cartridge is deteriorated.SOLUTION: A purge control method of an air tank includes: a first step S10 of compressing air in an air compressor; a second step S20 of removing moisture after compressing the air; a third step S30 of storing the air in the air tank; a fourth step S40 of measuring and determining the internal pressure of the air tank; a fifth step S50 of operating a first solenoid valve if the internal pressure of the air tank exceeds a predetermined pressure; a sixth step S60 of determining whether or not a second solenoid valve is operable; a seventh step S70 of operating the second solenoid valve; an eighth step S80 of operating a purge valve to remove moisture; a ninth step S90 of measuring and determining the internal pressure of the air tank again; and a tenth step S100 of turning off the first and second solenoid valves if the internal pressure of the air tank is less than a predetermined pressure.
