Corrosion inhibition effect evaluation device for corrosion inhibitor for oil field

The utility model discloses a corrosion inhibition effect evaluation device for a corrosion inhibitor for an oil field, which belongs to the technical field of corrosion inhibitors and comprises a mounting plate, the top of the mounting plate is fixedly connected with a box body and a lifting mechanism, a plurality of cylinders are embedded in the lifting mechanism, and the cylinders are connected with the box body and the lifting mechanism respectively. And a first piston is connected into the cylinder in a sealed and sliding manner. According to the corrosion inhibition effect evaluation device for the corrosion inhibitor for the oil field, a hook, a graduated drum and an elastic identification assembly are arranged, a sample coated with a slow-release agent is hung on the hook, the lifting mechanism drives the sample to be downwards placed in an acid solution of the box body, and after standing for a period of time, the weight of the sample is reduced according to the corrosion degree of the acid solution
