Pump parts volute pump liner
The volute pump liner is one of the most important wearing parts of horizontal slurry pumps. The horizontal slurry pump is widely used for conveying slurry containing abrasive solid particles in mining, electric power, metallurgy, coal, environmental protection and other industries. The features of the wearing parts are one of the key points of the slurry pump working.
The volute pump liner of slurry pump is mainly used to collect slurry and guide it. The volute pump liner forms a semi closed cavity for slurry pump to form a flow passage suitable for slurry flow and guide slurry flow to reduce energy loss. The kinetic energy of the high-speed slurry thrown out by the impeller is called static pressure energy. Because the slurry pump sheath bears a large positive impact force of the slurry when the pump is running, the wear is faster, which is basically consistent with the wear cycle of the impeller. When selecting the volute pump liner of slurry pump, the most important thing is to see whether there are obvious sand holes, air holes, and whether the channel surface is smooth and flat.
Generally, the materials of pump parts volute pump liner can be divided into metal , rubber and ceramics. Each material has its own applicable conditions. In the actual production, the volute pump line material is determined according to the concentration of the material transported by the slurry pump, the size of the object particles, and the pH of the slurry. Metal materials are often used to transport ore slurry with large particle size and sharp shape. Generally, the hardness of metal determines its resistance to wear. Metal materials with high shear hardness and compressive strength have strong resistance to wear of ore slurry.
