What are the characteristics of desulfurization slurry circulation pumps?
Thread Content
What are the characteristics of desulfurization slurry circulation pumps? 1. High flow rate, large diameter, low rotational speed, high voltage, low current. Since pump wear is proportional to the pump speed, slurry circulation pumps all operate at lower speeds. 2. The body is heavy. The pump’s volute and impeller are thick, with large external reinforcement ribs, and its bearings are much larger than those of ordinary centrifugal pumps. 3. The structure is easy to maintain. A bolt-through connection is used, allowing all flow-through components to be replaced. 4. Anti-friction design. The large area ratio at the inlet and outlet of the impeller reduces wear on the flow-through components. The sealing structure prevents solid particles from entering ； Evacuation vanes are located before and after the impeller, which can reduce the pressure on the mechanical seal. 5. It has sufficient suction head. There is an appropriate net positive suction head to accommodate a small amount of gas present (
