Abstract

The invention belongs to the technical field of wear test devices, and in particular relates to a tank type erosion wear test device and method. The tank type erosion wear test device comprises a bracket and a test sample clip, wherein the bracket is provided with a rotatable hollow roller; the hollow roller is provided with a sealing cover; a through hole is formed in the hollow roller or the sealing cover; the test sample clip is arranged in the hollow roller and is connected with the bracket; when the hollow roller rotates, the test sample clip is static and immobile; a blade is arranged on an inner wall of the hollow roller. According to the tank type erosion abrasion testing device and method, types of slurry milling materials, pH (Potential of Hydrogen) values of slurry, an erosion linear speed of a test sample and an erosion angle all can be adjusted, and the tank type erosion wear test device is applicable to researches on performance of wear-resisting materials; the position of the test sample in the hollow roller can be adjusted through a displacement device, and demands on the size of the test sample are not strict; tests for erosion wear performance of the test sample at different positions are realized; the adjustment of the erosion angle in a range of 0 to 90 degrees can be realized by adjusting the test sample clip.

Description

technical field [0001] The invention belongs to the technical field of wear test devices, and in particular relates to a tank type erosion wear test device and a method. Background technique [0002] The wear performance of materials is a topic of concern to researchers. On the one hand, wear is the main form of component failure, especially in metallurgy, mining, construction machinery, electric power, coal, petroleum and other fields; on the other hand, the economic loss caused by wear is also huge. More than 3 million tons, nearly 15 billion US dollars, of which abrasive wear accounts for more than 50%. Therefore, it is necessary to research and develop new erosion wear devices. [0003] There are many classification methods for erosion and wear test devices, and the common classification methods are jet type, vacuum drop type and tank type. Due to its simple structure and numerous advantages, the tank test device is mostly used for erosion and wear tests of wear-resis...

Problems solved by technology

[0005] 2. The erosion angle is an important factor affecting the wear resistance of wear-resistant materials. At present, the adjustment and control of the erosion angle of the domestic tank-type erosion wear test device is mostly realized by changing different sample discs or fixtures. Not only It is inconvenient in actual use, and the angle adjustment range is very limited, which greatly affects the application range of the tank type erosion wear test device

[0006] 3. The non-uniform slurry concentration of the tank-type erosion wear device at low speed and high concentration is a disadvantage that cannot be ignored

[0007] 4. Most of the existing tank-type erosion and wear test devices are eroded by the mud body when the sample is rotating, and mostly fixed by wear-resistant materials when working, and are eroded by the flowing mud (for example: the bushing in the pump, Cyclone lining), the existing tank-type erosion wear test device can not be well simulated, which is not conducive to the study of the erosion wear performance of wear-resistant materials
