Erosion corrosion interactive wear simulation test device

Abstract

The invention discloses an erosion corrosion interactive wear simulation test device. The device comprises a clamp unit, a fluid power unit, a working motor, a test barrel body, a thermometer, a bottom heating device and a rotating shaft. Eight bolt holes are formed in the outer surface of a clamp sealing connecting plate and used for being fixed to the test barrel body and achieving the sealing effect, and cuboid blocks are welded to the inner surface of the clamp sealing connecting plate and slotted. The clamp rotating shaft is installed in a through hole in the clamp sealing connecting plate, and the two ends of the clamp rotating shaft are each provided with an anti-skid micro groove with the length of 30 mm. Stirring blades are in a hinge shape, the bending angle is 25 degrees, and the stirring blades are fixed to blade fixing pieces through bolts. Compared with the prior art, the test device has the advantages that the test piece is in a fluid erosion corrosion environment all the time, the actual working condition of the inner wall of a pipeline is simulated to the maximum extent, the test piece is installed on the barrel wall more stably and reliably relative to rotation ofthe test piece, the fluid erosion speeds of different depths can be monitored in real time, multiple test pieces can be tested at different angles at the same time, and the efficiency is high.

Description

technical field [0001] The invention relates to an erosion-corrosion wear test device, in particular to an erosion-corrosion interactive wear simulation test device. Background technique [0002] Petrochemical pipelines are important transportation equipment in the field of oil drilling, and liquid-solid two-phase or single-phase fluids are the most common transportation media. During transportation, the above-mentioned fluid media have both erosive and corrosive wear effects on the pipeline. There is an interaction between the two at the same time. It has been found through research that when there is an interaction between the two, the inner wall of the pipeline will be greatly damaged, and in severe cases, the pipeline will break. Therefore, the research on the erosion and corrosion wear mechanism of the inner wall of the pipeline is quite important. [0003] At present, scholars have studied erosion or corrosion by designing test devices, and have come to a conclusion by...

Problems solved by technology

[0003] At present, scholars have studied erosion or corrosion by designing test devices, and have come to a conclusion by observing the erosion or corrosion wear on the surface of the test piece. However, most of the test devices have limitations or deficiencies: they cannot simulate both erosion and corrosion. The environment, the test piece cannot be immersed in the fluid medium, the number of test pieces is small, the erosion rate is unpredictable, and the erosion efficiency is low, etc., which cannot truly simulate the internal environment of the erosion-corrosion pipeline, and the experimental results obtained are inaccurate
