The invention relates to a pretreatment method for industrial coating of a hydraulic workpiece. The pretreatment method comprises the steps that S1, other attachments except greasy dirt on the outer surface of the hydraulic workpiece are removed; s2, oil stain treatment is conducted, specifically, the hydraulic workpiece treated in the S1 is soaked and washed with circulating alkaline water so as to remove oil stains on the hydraulic workpiece; s3, anti-flash-rust treatment is conducted, specifically, the hydraulic workpiece treated in the S2 is soaked and washed in a sectional mode through a circulating anti-flash-rust agent; and S4, the hydraulic workpiece treated in the S3 is directly used for industrial coating after being dried. The method has the beneficial effects that the adhesive force of a coating object is improved, the coating repair rate is reduced, the defects that degreasing of a traditional stand column and a jack is affected by the environment and the process is complex before the water paint coating process are overcome in the whole degreasing process, the process is simple and efficient, meanwhile, it is ensured that the green manufacturing target is achieved, and the production cost is reduced. The purposes of energy conservation, emission reduction and cost reduction are achieved.
