Abstract

The invention belongs to the technical field of wear test devices, in particular to a tank-type erosion wear test device and method, a tank-type erosion wear test device, including a bracket and a sample holder, and the bracket is provided with a rotatable hollow drum, the hollow drum is provided with a sealing cover, the hollow drum or the sealing cover is provided with a through hole, the sample holder is arranged inside the hollow drum and connected with the support, when the hollow drum rotates, the sample The clamp is stationary, and blades are arranged on the inner wall of the hollow cylinder; the type of slurry abrasive, the pH value of the slurry, the erosion linear velocity and the erosion angle of the sample of the present invention can be adjusted, and are suitable for wear-resistant materials. Performance research; through the displacement device, the position of the sample clamp in the hollow cylinder can be adjusted, and there is no strict requirement on the size of the sample, so that the test of the erosion and wear performance of the sample at different positions can be realized; by adjusting the sample clamp, it can be realized The erosion angle can be adjusted within the range of 0 to 90 degrees.

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
