Working principle and application of hose pump: The hose is arranged in a U-shape in the pump body. When the rotating body drives the extrusion wheel to rotate, the extrusion hose is elastically deformed by the extrusion wheel, and then the suction port forms a negative pressure suction slurry. By the push of the squeeze wheel, the slurry is discharged from the discharge port, forming a pressure transfer of the slurry. Industrial hose pumps are mainly used for the long-distance transportation of viscous slurry in the fields of construction, underground engineering, mining, food, papermaking, ceramics, metering pumping, pressure grouting, spraying, etc.
