Purpose of Slurry Pump

Oct. 28, 2020

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, slag slurry pump mine 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.

The scope of application of Slurry pump

First of all, about 80% of applications in concentrators are used in concentrators in the mining industry. Because the primary ore selection industry is relatively harsh, the service life of the slurry pump is generally low in this section. Of course, different ores have different corrosivity. For example, the relative abrasiveness is reduced in the concentrate transportation and other sections, and the overall service life of the pump is also longer. Therefore, when the general user often asks about the service life of the supplier’s product during the procurement process, strictly speaking, any manufacturer will not promise the user an accurate service life cycle without basis, because the service life of the overcurrent component ( The service life of wear-resistant and corrosion-resistant parts depends on many different factors. The diversity and complexity of working conditions result in different service life of materials of the same quality. However, in the early selection stage, powerful manufacturers can make reasonable design selection for working conditions.

Secondly, in the power industry, it is mainly thermal power plants. At present, my country’s power plants are mainly thermal power and hydropower. 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 to a certain extent. After a large amount of water, the slurry pump is used to transport it to the place where the ash is piled. Therefore, sometimes the slurry pump is also called the ash pump in the power plant.

Third, in the coal washing industry, due to different working conditions, large coal lump and coal gangue are easy to block, which requires high design requirements for slurry pumps.

In the field of seawater sand selection, the application of slurry pumps has gradually been recognized by customers. However, when sand is selected in seawater and sand is dug in rivers, slurry pumps are more easily called sand pumps or dredging pumps. Although they are called differently, in terms of structural features and pump performance principles, they can all be called slurry pumps. Therefore, we often call sand pumps in seawater sand selection, and they are customarily called dredging pumps in river dredging. .

Although centrifugal slurry pumps have a wide range of uses, the correct application is very important. Due to the limitations of the name of the slurry pump, some people outside the industry have misunderstood this. In fact, mud pumps, impurity pumps, dredging pumps, dredging pumps, etc. are all in the scope of application of slurry pumps. In the application process of the slurry pump, we must pay attention to reasonable design, correct calculation, and appropriate selection. These points are very important.
