Tobee Slurry pump Volute Liner D3110A49 is an important wear part of 4/3C-AH and 4/3D-AH slurry pumps.
Slurry pumps are often used for the transportation of high-concentration and corrosive fluids. Due to the strong corrosive and frictional properties of the transported fluids, the slurry pump sheath has higher requirements for wear and corrosion resistance.
Generally, the wear-resistant materials of slurry pumps include wear-resistant materials, which can be divided into metal wear-resistant materials, rubber, and ceramics. Each material has its own applicable conditions. In the actual production, it depends on the concentration and object of the material conveyed by the slurry pump. Determine the size of the particles and the pH of the slurry. Metal wear-resistant materials are often used for slurry transportation in concentrates with large particle sizes and sharp shapes. Usually, the hardness of the metal determines its resistance to abrasion. Metal materials with higher shear hardness and compressive strength have abrasion resistance to the slurry. Strong ability.
Among the metal materials, the hard nickel material is harder and has strong abrasion resistance to sharp materials. However, this aggregate texture is relatively brittle and is susceptible to large deformation and damage. Therefore, it is not suitable for the manufacture of dredging pumps with high coarse particle content. The wear resistance of Cr26-28 is similar to that of nickel alloy. It has strong resistance to abrasion of particles with a particle size greater than 100μm, and at the same time, it has good resistance to corrosion of materials with a pH between 5 and 12. Common materials for flow parts. Cr15Mo3 is recognized as a material with better wear resistance, but it is more expensive and brittle in texture. The wear resistance of rubber is better than that of alloy materials, and it is a wear-resistant material often used in slurry pump volute liner.
