Slurry pumps (submerged slurry pumps, submersible slurry pumps, and wear-resistant slurry pumps) are general-purpose machinery widely used. In various sectors of the national economy, slurry pumps are indispensable mechanical equipment for transporting various liquids. Can not do without it. ,
For example, in a thermal power plant, the feedwater slurry pump sends water to the boiler; the circulating water slurry pump sends cooling water to the steam turbine condenser; the condensate slurry pump discharges the condensed water in the condenser; Relay water slurry pump for increasing water flow pressure between them; hydrophobic slurry pump for removing water from all parts of the thermal system; water supply slurry pump for supplementing water to the heating network system and water slurry pump for supplementing softened water to the thermal system Wait. These slurry pumps are important auxiliary equipment for thermal power plants. In addition, there are special-purpose slurry pumps for conveying various lubricating oils, and chemical liquids and removing boiler ash.
Slurry pumps are widely used in mines, thermal power plants, metal smelting, coal washing plants, environmental protection, and other industries to transport some slurry containing abrasive solid particles. For example, in the transportation of ore slurry in metallurgical beneficiation, in the ash removal process of slag in thermal power plants, in the transportation of coal slurry and heavy medium in coal washing plants, in the process of dredging and dredging rivers, etc. In the chemical industry, it is also possible to transport some corrosive slurries containing crystalline objects.
First of all, the mineral processing plant, about 80% are used in the mineral processing of the mining industry. The working conditions in the process of primary separation of dry ore are relatively harsh, so in this segment, the service life of the cleaning pump is generally low. Of course, different ores are different, and the abrasiveness will also be different. If the relative abrasiveness is reduced in the lower section such as concentrate transportation, the overall service life of the pump will be longer.
At present, the power plants in our country are mainly thermal power plants and hydropower plants. However, in the process of generating electricity in thermal power plants, a large amount of coal will be used to generate electricity, and the slag or ash after coal combustion needs to be cleared, so the slurry pump is also used in this process of ash removal. The slag will be mixed with a certain amount of water, and then transported to the place where the ash is stacked through the slurry pump, so there is Sometimes slurry pumps are also called ash pumps in power plants.
When selecting sand in seawater, the application of slurry pumps has gradually been recognized by customers. Generally, when selecting sand in seawater or controlling sand in rivers, cleaning pumps will also be called sand pumps or mud control pumps. However, although The names are different, but if you look at the structural characteristics and the performance principle of the pump, they can all be called slurry pumps.
Slurry pumps may cause some misunderstandings due to the limitations of their names. In fact, mud pumps, impurity pumps, dredging pumps, dredging pumps, etc. are also used in the application of slurry pumps. Within the range, and in the application process of the slurry pump, we must also pay attention to the reasonable design of the slurry pump, correct calculation, and appropriate selection. These points are very important.
