Abstract

The invention discloses a spin type multiphase flow erosion wear test machine, which consists of a slurry cylinder, a motor, a rotation shaft and a rotary table. The motor is disposed above the slurry cylinder through a bracket, one end of the rotation shaft is connected to a motor output shaft, the other end of the rotation shaft is equipped with the rotary table, the rotation shaft passes through a top plate of the slurry cylinder so as to dispose the rotary table in the slurry cylinder, and the rotary table is equipped with a test piece holder. The slurry cylinder is internally equipped with a plurality of baffle plates, one sides of which are connected to the slurry cylinder. When the test machine works, a test piece is mounted on the rotary table through the test piece holder, the motor drives the rotary table to rotate through the rotation shaft, slurry also rotates along with the rotary table, the baffle plates in the slurry cylinder have an obstruction effect on rotation of the slurry, and further can generate certain eddy current so as to reach certain scouring effect on the test piece. The test machine provided by the invention can simulate the scouring form in actual working conditions, provides important data for actual engineering pipeline scouring wear prediction, and provides reference for ensuring safe operation of pipelines.

Description

technical field [0001] The invention relates to an erosion wear test device, in particular to a spin-type multiphase flow erosion wear test machine. 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 flow of water-containing, corrosive, and multiphase flow media is more complicated, and it is difficult t...
