Abstract

The invention discloses a test piece gripper, used for a spin multiphase flow erosive wear test machine, and comprising a base and two clamp splices; each clamp splice is a half-cylinder; one end of each clamp splice is provided with a nip, the other end is provided with a half flange plate, and the central part is provided with a mounting hole; a test piece is gripped by the nips of the two clamp splices, the two clamp splices are connected and fixed through the mounting hole, and are connected with the base through the flange plate; the base is arranged on a turntable of the erosive wear test machine and can adjust angle installation of the test piece. The test piece gripper is capable of distributing a plurality of identical test pieces at different mounting angles, so that every test piece is different in impact angle in a test process, and the relationship between the impact angles and erosive wear speed can be obtained, thus improving accuracy of erosive wear test, providing important data for the actual engineering pipeline erosive wear prediction, and providing reference for ensuring the safe operation of a pipeline. The invention also discloses a spin multiphase flow erosive wear test machine.

Description

technical field [0001] The invention relates to an erosion wear test device, in particular to a specimen holder. In addition, the present invention also provides a spin-type multiphase flow erosion wear tester with the above-mentioned specimen holder. Background technique [0002] Fluid pipelines are special equipment for transporting fluids under certain pressure. With the development of the economy, fluid pipelines are widely used in the transportation of various fluid materials in the fields of crude oil, natural gas, tap water, urban liquefied gas and process industries. [0003] The study found that pipeline failure has various forms and complex mechanisms, such as material defects, corrosion, wear, external force damage, etc. Among them, wear failure caused by erosion and wear damage is the most common and common damage form in pipeline systems. Erosion wear damage has obvious locality, suddenness, and risk, especially the erosion wear and perforation caused by the f...
