Abstract
El modelo de utilidad revela una estructura de sellado para disco succion de bomba de pulpa que pertenece al campo tecnico de la bomba de pulpa, la estructura del sellado incluye un conjunto de paletas en forma de arco de disposicion a lo largo de la direccion circunferencial en la superficie frontal de la cubierta delantera del impulsor, las paletas y la cubierta delantera del impulsor tienen la conexion fija. Se tiene la seccion de espacio libre entre los paletas y disco succion, el intervalo entre las paletas adyacentes se incrementa gradualmente por el interior que esta cerca de la linea del eje de la cubierta delantera del impulsor hasta el borde exterior que esta cerca de la pared exterior de la cubierta delantera del impulsor y la direccion de extension de flexion del extremo exterior de las paletas es opuesta a la direccion de atornillado de la cubierta delantera del impulsor. En el proceso de rotacion de las paletas impulsadas por la cubierta delantera del impulsor, el van puede empujar la escoria entre las paletas adyacentes hacia afuera, de modo que se puedan descargar particulas solidas grandes, la abrasion entre la cubierta delantera del impulsor y el disco succion se puede reducir, la velocidad de abrasion de disco succion se reduce, la vida util de disco succion se prolonga y se ahorra el costo.The utility model reveals a pulp pump suction disc sealing structure belonging to the technical field of the pulp pump, the sealing structure includes a set of arc-shaped vanes of arrangement along the circumferential direction in the front surface of the front impeller cover, the vanes and the front impeller cover have the fixed connection. There is the section of free space between the vanes and suction disc, the interval between the adjacent vanes is gradually increased from the inside which is close to the axis line of the front impeller cover to the outside edge which is close to the wall outer end of the impeller front cover and the bending extension direction of the outer end of the blades is opposite to the bolting direction of the front impeller cover. In the process of rotating the blades driven by the front impeller cover, the van can push the slag between the adjacent vanes outward, so that large solid particles can be discharged, the abrasion between the front impeller cover and the disc. The suction disc can be reduced, the abrasion speed of the suction disc is reduced, the service life of the suction disc is prolonged, and the cost is saved.
