Common abrasion phenomenon of water pump

Abrasion (erosion, erosion) refers to a kind of wear caused by the impact of multiphase flow medium on the surface of materials. The phenomenon of water pump abrasion has become one of the main causes of material damage in many industrial sectors. It is considered that abrasion accounts for 8% of the total wear damage in industrial production.

According to the flow medium, the abrasion phenomenon of water pump can be divided into two categories, i.e. air blast abrasion and liquid flow or water drop abrasion. The second phase carried in the flowing medium can be solid particles, liquid drops or bubbles. Some of them directly impact the surface of the material, while others collapse (bubbles) on the surface, thus exerting mechanical force on the surface of the material. According to the arrangement and combination of flow medium and second phase, the abrasion phenomenon of water pump can be divided into four types

The abrasion caused by the impact of solid particles carried by the liquid medium on the surface of the material is called slurry abrasion. The flow passage parts of mud pump and slurry pump used in the construction industry, oil drilling, coal mining, metallurgical industry and thermal power station are seriously abraded. In recent years, people have been committed to the comprehensive development and utilization of coal resources. In the gasification, liquefaction (preparation of kerosene slurry and coal water slurry), transportation and combustion of coal, there are a lot of material erosion problems. Whether some advanced processes and designs can be realized or not is even based on the complete understanding of the abrasion of materials or components.
