Rotary experimental device for simulating erosion corrosion of inner wall of pipeline

The utility model relates to the field of erosion-corrosion devices, specifically, a rotary experimental device for simulating the erosion corrosion of the inner wall of a pipeline, which solves the problem that the existing rotary erosion-corrosion experimental device cannot well simulate the erosion corrosion of the inner wall of the pipeline, while a pipe-flow type erosion-corrosion experimental device has high construction cost. The device is provided with a rotary shaft, a slurry tank, a sample clamp and an annular sample, wherein the upper part of the rotary shaft is provided with a carbon brush; the carbon brush is connected with electrochemical test equipment; the rotary shaft is connected with the output terminal of a motor with a frequency converter; the lower part of the rotary shaft extends into the slurry tank and above slurry; the rotary shaft is connected with the sample clamp through an adapter; and the annular sample is arranged on the sample clamp. The utility model has the advantages of existing rotary and pipe-flow type erosion-corrosion experimental devices, studies the axial erosion-corrosion behavior of the inner wall of a pipe in the rotating conditions, controls the flow rate, medium composition and temperature, and achieves real-time electrochemical parameter measurement and weight loss measurement simultaneously.
