<P>PROBLEM TO BE SOLVED: To provide a maintenance method of a hydraulic circuit capable of inspecting abnormality caused in a supply-discharge pipe in a short time by partitioning the supply-discharge pipe into a plurality of sectional circuits. <P>SOLUTION: This maintenance method of the hydraulic circuit includes a damage part detecting process constituted of a damage inspection area constituting process of being constituted by cutting off a stop valve on the most downstream side of the plurality of continuous sectional circuits, a pressurizing force holding process of capable of performing inspection by holding pressure by cutting off a stop valve on the upstream side of a damage inspection area of the damage inspection area constituting process in a state of pressurizing the damage inspection area, and a damage detecting process of detecting the existence of damage by measuring a degree of reducing the pressure in a specific time in the damage inspection area in which the pressure is held by the pressurizing force holding process. <P>COPYRIGHT: (C)2012,JPO&INPIT |
