Slurry pumps can be widely used in mining, electric power, metallurgy, coal, environmental protection and other industries to transport slurry containing abrasive solid particles. Such as metallurgical beneficiation plant ore slurry transportation, thermal power plant hydraulic ash removal, coal washing plant coal slurry and heavy medium transportation, river dredging, river dredging, etc. In the chemical industry, some corrosive slurries containing crystals can also be transported. First of all, about 80% of applications in concentrators are used in concentrators in the mining industry. Due to the harsh working conditions of the primary ore selection, the service life of the slurry pump is generally low in this section. Of course, different minerals have different abrasiveness. For example, the relative abrasiveness of the work section such as concentrate transportation is reduced, and the overall service life of the pump is also longer. Therefore, when ordinary users often ask about the service life of the supplier’s products during the procurement process, strictly speaking, any manufacturer will not promise users an accurate service life cycle without basis, because the service life of the overcurrent parts The service life of (wear-resistant and corrosion-resistant parts) depends on a variety of different factors. The diversity and complexity of working conditions lead to differences in the service life of materials of the same quality. However, in the early selection stage, powerful manufacturers can make reasonable selection and design of working conditions for them.　　Secondly, in the power industry, mainly thermal power plants. At present, my country’s power plants are mainly thermal power generation and hydropower generation. In thermal power plants, due to the large amount of coal-fired power generation, the slag or ash after coal combustion needs to be removed. The slurry pump is used to remove ash and slag. The slag is mixed After a certain amount of water, the slurry pump is used to transport it to the place where the ash is piled up. Therefore, sometimes the slurry pump also becomes the ash pump in the power plant.
