Rotary test device for simulating erosion corrosion on inner wall of pipeline

The invention relates to the field of an erosion corrosion device and particularly provides a rotary test device for simulating the erosion corrosion on an inner wall of a pipeline, and overcomes the defects that the conventional rotary erosion corrosion test device cannot simulate the erosion corrosion on the inner wall of the pipeline well and a pipe flow type erosion corrosion test device is high in manufacturing cost. The rotary test device disclosed by the invention is provided with a rotating shaft, a slurry tank, a sample clamp and an annular sample. A carbon brush is arranged at the upper part of the rotating shaft and is connected with electrochemical test equipment; the rotating shaft is connected with an output end of a motor which is provided with a frequency converter; the lower part of the rotating shaft extends to a place above slurry in the slurry tank; the rotating shaft is connected with the sample clamp through a rotary joint; and the annular test is mounted on the test clamp. The rotary test device disclosed by the invention combines the advantages of the conventional rotary erosion corrosion test device with the conventional pipe flow type erosion corrosion test device, so that axial erosion corrosion behaviors on the inner wall of the pipe are researched in a rotated condition. According to the rotary test device disclosed by the invention, the flow speed, the medium component and the temperature can be controlled, and real-time electrochemical parameter measurement and zero gravity measurement can be realized simultaneously.
