Technical Field
[0001] The utility model relates to the technical field of slurry pumps, in particular to a material backflow prevention structure for material pumping. Background Art
[0002] The slurry pump is a centrifugal pump in terms of its working principle. It is a machine that increases the energy of a solid-liquid mixed medium by using the action of centrifugal force, and is a device that converts electrical energy into kinetic energy and potential energy of the medium.
[0003] The swing cylinder of the slurry pump has a process of separation and docking with the two main oil cylinders when swinging. In this process, when the swing cylinder and the main oil cylinder are not completely separated and docked, there is a gap connected to the silo. Driven by the pipeline pressure and the drop in height, the material will flow back into the silo through the gap between the swing cylinder and the main oil cylinder, causing part of the material that has been pumped out to flow back into the silo, greatly reducing the pumping efficiency.
