Application Practice of Slurry Pump in Metallurgical Industry
Transport medium
In the metallurgical industry, slurry pumps are mainly used to transport high-temperature molten metals, aluminum liquids, and other liquids containing solid particles, as well as to extract metallurgical waste residue, such as blast furnace slag, steel slag, and waste residue from non-ferrous metal smelting.
Application scenarios
Slurry pumps are widely used in the transportation of slurry in metallurgical plants, the transportation of solid particles generated by coal combustion in thermal power plants, and the transportation of coolant and other liquids containing solid particles in nuclear power plants.
Application of different types of slurry pumps
Centrifugal slurry pump: It is the most common type, suitable for transporting fluids containing larger particles, and can be used in the metallurgical industry to transport slurry with larger particles.
Axial suction slurry pump: suitable for conveying fluids with high temperature, high pressure, and strong corrosiveness, and can meet the needs of some special working conditions in the metallurgical industry.
Mixed flow slurry pump: suitable for situations that require high flow rates and want to reduce operating noise. It can play a role in certain aspects of metallurgical production that require high flow rates and noise control.
Problems in the application of slurry pumps in the metallurgical industry
Serious equipment wear and tear
In mineral processing production, slurry pumps are important energy consuming equipment that often require frequent replacement and maintenance. During maintenance, improper operation can lead to severe equipment wear and tear, thereby affecting the service life of the slurry pump. Meanwhile, the abrasives generated during the metallurgical process are prone to wear on the inner wall of the pump chamber during transportation. Once there is wear on the inner wall of the pump chamber, it may lead to leakage or performance degradation.
High viscosity of conveyed materials
Slurry pumps usually need to transport slurry with high viscosity, such as desulfurization gypsum, phosphate paste, etc. These materials have high viscosity and are prone to forming material clumps, which can cause blockage, reduced performance, or even damage to the slurry pump.
Improper selection
The production environment in the metallurgical industry is relatively complex, and slurry pumps need to choose different pump types, structures, and materials according to different working conditions and special environments. However, in actual use, due to unprofessional workers and inadequate equipment management, improper selection may occur, resulting in a decrease in the performance of the slurry pump.
Improvement measures for slurry pumps in the metallurgical industry
Adopting a new slurry pump
ZJ slurry pump is a new type of wear-resistant pump, which has the advantages of small volume, high power, low energy consumption, and less blockage, and is widely used in industries such as metallurgy. It is made of high-strength alloy material, which has good wear resistance and corrosion resistance, and can be transported for a long time in high temperature, high pressure, and strongly corrosive environments; By adopting a new impeller structure and optimized liquid flow design, the efficiency of the pump has been greatly improved, ensuring higher output at the same power; By using a magnetic propulsion device, the pump operates more stably and smoothly, effectively preventing abnormal vibrations and sudden shutdowns; The use of a shunt sleeve or dual machine seal design can effectively avoid problems such as wear and seal failure in the pump chamber, improving the service life and safety of the pump.
Optimize selection
Select appropriate pump types, structures, and materials based on different working conditions and special environments in the metallurgical industry. For example, for high temperature, high pressure, and highly corrosive working conditions, axial suction slurry pumps are preferred; For situations that require high flow and low noise, choose mixed flow slurry pumps, etc.
Strengthen maintenance and management
Develop standardized maintenance operation procedures, strengthen training for workers, improve their professional level, and ensure that the maintenance work of slurry pumps is standardized and in place. Regularly inspect and maintain the slurry pump, promptly identify and address issues such as equipment wear and seal failures, and extend the service life of the slurry pump.
technological innovation
In hydraulic design, structural design, and the use of wear-resistant materials, the advantages of similar products at home and abroad are comprehensively applied and innovated. Some slurry pumps have innovated in hydraulic and structural design, using wear-resistant materials for the flow passage components to improve the efficiency, energy saving, wear resistance, and anti clogging ability of the slurry pump.
