Description

Technical Field

[0001] This utility model relates to a wear testing device, specifically to a computer-controlled, visualized high-temperature gas-solid erosion wear testing device. Background Technology

[0002] In industries such as thermal power plants, petrochemicals, coal chemicals, and natural gas transportation, equipment frequently faces high-temperature, high-speed erosion and wear caused by solid particles, severely impacting its service life and safety. For example, boiler heat exchange tubes in thermal power plants are eroded by fly ash particles during combustion, leading to wear and shortened lifespan; in natural gas pipeline transportation, airflow carrying solid particles can severely erode pipe bends and other parts, causing perforation and other hazards. Although coatings and new materials can effectively improve erosion resistance, their wear resistance must be verified through simulation tests before practical application to reduce the high cost and long cycle of on-site testing. Pressure equipment faces multi-mechanism coupled damage such as multiphase erosion, cavitation, and multi-media flow corrosion, often leading to unplanned downtime. Although existing standards can provide corrosion rates under different conditions, the lack of data and models for multi-mechanism coupled damage makes it crucial to study these mechanisms, experimentally measure damage rates, investigate erosion and wear patterns, and control wall thickness loss for equipment safety and to reduce production accidents.

[0003] Despite extensive research, the erosion wear mechanism still requires further investigation due to the complexity of operating conditions and varying particle properties, especially the failure mechanism under flowing and wetting conditions. Existing laboratory high-temperature gas-solid erosion experimental setups suffer from the following main defects in structure and functionality, which affect experimental stability and measurement accuracy: Specimen position misalignment: During erosion experiments with specimens under different angle conditions, a significant difference exists between the original centering distance and the newly generated distance, leading to changes in the impact distance and affecting experimental results. Insufficient automation: Given the harsh experimental environment of high temperature, high speed, and dust, manual adjustments to these conditions require manual movement of the test bench, along with visual and experience-based calibration, resulting in low efficiency. Insufficient experimental progress: The lack of a computer-controlled numerical control system makes it difficult to accurately achieve specified angles, heights, and displacements. Difficulty in determining particle impact velocity: Conventional calculation methods use pressure gauge readings to calculate the particle velocity before impact, which contains errors compared to the actual value. Using uniformly distributed sensors would provide more accurate calculations. While these technologies can meet the needs to some extent, they still have significant limitations in terms of efficiency, testing accuracy, and applicability. In summary, developing a visual gas-solid erosion wear testing device suitable for complex environments has important academic and engineering value. Utility Model Content

[0004] To address the problems existing in the background technology, this utility model provides a computer-controlled, visualized high-temperature gas-solid erosion wear experimental device. This device addresses the issues of low automation and low accuracy in centering during material supply and erosion testing. It is widely applicable to high-temperature gas-solid two-phase erosion testing of materials, especially for the study of the entire erosion process. To significantly improve the experimental efficiency and shorten the experimental cycle of the loop-type testing device, this utility model designs a multiphase erosion and flow-coupled damage acceleration test unit and test structure without increasing the device size. This improves automation and test accuracy, solves the problem of prolonged cycle time caused by multi-condition testing, and realizes accelerated testing of pipelines damaged by multiphase erosion and flow corrosion under multiple conditions. It provides data support for setting damage safety boundaries and risk assessment of pressure equipment, and guides wear prediction and safety control in complex environments.

Nozzle 18 is used to achieve concentric erosion; the air compressor 1 is turned on by opening the air inlet valve and starting the air compressor until the pressure gauge reading of the pressure stabilizing tank 3 stabilizes to the preset pressure value. Then, the rotary valve 21 is opened to mix the erosion particles with the air in the gas-solid two-phase mixing chamber 22. During the experiment, the values ​​of pressure gauges 8 and 24, flow meter 23 and pressure sensors 19 and 20 are monitored in real time and do not exceed their respective preset ranges.

[0050] After the erosion is completed, shut down the air compressor 1, the digital temperature-controlled air heat exchanger 4, and all valves, and remove the recovery unit 15; the exhaust gas, carrying some particles, enters the cyclone separator 14 to separate the erosion exhaust gas from the particles.

[0051] After the experiment, the computer 10 first shuts down motors 1107, 1206, and 1311, restoring each module to its initial position; then, the air compressor 1 and ball valve 2 are shut down in sequence. After the pressure gauge reading of the pressure tank 3 returns to zero and remains unchanged, the regulating valve 5, shut-off valve 6, butterfly valve 7, digital temperature-controlled air heat exchanger 4, and rotary valve 21 are closed; the interior of the erosion chamber is observed through the observation window 25. After the particle movement inside the chamber has completely subsided, the hatch is opened, the recovery unit 15 is removed, and the particle waste around the experimental device is cleaned up, thus ending the experiment.
