Application Challenge

Improper selection of pump type

The mining production environment is complex, and slurry pumps need to choose different pump types, structures, and materials according to different working conditions and special environments. However, in practical use, due to unprofessional workers and inadequate equipment management, improper selection may occur, resulting in a decrease in the performance of the slurry pump.

Serious equipment wear and tear

In mining production, slurry pumps are important energy consuming equipment that often require frequent replacement and maintenance. However, improper operation during maintenance can lead to severe equipment wear and tear, thereby affecting the service life of the slurry pump.

Material transportation issues

Slurry pumps are usually used to transport slurry materials 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. Meanwhile, the abrasives generated during the beneficiation production 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.

International market competition pressure

From the overall perspective of the industry, Chinese slurry pump enterprises need to face competitive pressure from well-known foreign brands and challenges such as trade protectionism in the international market competition, which indirectly affects the related supporting services and costs of using domestic slurry pumps in the mining industry.

Response measures

Scientific and rational selection

Select the appropriate pump type, structure, and materials based on the specific working conditions of the mine, such as the properties of the slurry (particle size, concentration, viscosity, corrosiveness, etc.), transportation distance, and head requirements. For example, for conveying fluids containing larger particles, a centrifugal slurry pump can be chosen; For transporting fluids with high temperature, high pressure, and strong corrosiveness, an axial suction slurry pump can be selected.

Standardize equipment maintenance

Strengthen professional training for operators, improve their operational skills and maintenance awareness, and ensure standardized operation during the use and maintenance of slurry pumps. Establish a comprehensive equipment maintenance management system, regularly inspect, maintain, and repair slurry pumps, promptly identify and address equipment wear and tear issues, and extend equipment service life.

Handling and transporting materials

For materials with high viscosity that are prone to clumping, some pre-treatment measures can be taken, such as adding dispersants, heating, etc., to reduce the viscosity of the material and minimize the possibility of clumping. To address the issue of easy wear in the pump chamber, materials with good wear resistance and corrosion resistance can be used to manufacture the pump chamber, or slurry pumps with diversion sleeves or dual machine seal designs can be used to effectively avoid wear and seal failures in the pump chamber.

Enhance the competitiveness of domestic pumps

For the indirect impact of international market competition, domestic slurry pump enterprises should increase research and development investment, enhance independent innovation capabilities, optimize product structure, strengthen brand building, produce efficient, energy-saving, and environmentally friendly slurry pump products, improve the competitiveness of domestic slurry pumps in the international market, and provide higher quality and more cost-effective products and services for the mining industry.
