ElGranalladora con transportador de rodilloses un equipo industrial utilizado para el tratamiento superficial de materiales metálicos. Limpia impurezas como incrustaciones de óxido y óxido en la superficie de las piezas de trabajo mediante granallado de alta velocidad. Los siguientes son los puntos claves para su uso y mantenimiento:


Funciones principales y estructura


Principio de funcionamiento: Las piezas de trabajo se transportan mediante transportadores de rodillos. La superficie de las piezas de trabajo se impacta mediante granallado de alta velocidad mediante granalladoras. Combinado con un sistema de eliminación de polvo y un dispositivo de circulación de granalla, se consigue una limpieza continua.


Componentes principales: incluido el sistema transportador de rodillos, la máquina de granallado (incluido el impulsor, la jaula de control, etc.), el dispositivo de eliminación de polvo (filtro de bolsas), el separador (transportador de tornillo) y el sistema de control eléctrico.


Precauciones de uso

Verificar antes de la operación

Confirme que las partes vulnerables como el impulsor, las palas y la jaula de control de la granalladora no estén desgastadas ni dañadas.

Compruebe si el transportador de rodillos gira con flexibilidad y si no hay deformación en la superficie del transportador de rodillos.

Verifique que las bolsas de filtro del sistema de eliminación de polvo no estén dañadas y que el ventilador esté funcionando normalmente.

Preparación de materiales

Seleccione la granalla adecuada (como granalla de acero o granalla de hierro fundido) según el material de la pieza de trabajo para garantizar que el tamaño de partícula y la dureza cumplan con los requisitos del proceso.


Protección de seguridad

Los dispositivos de sellado en la entrada y salida de la pieza de trabajo deben estar bien cerrados para evitar salpicaduras de granalla.

Está estrictamente prohibido abrir la cubierta protectora o la puerta de mantenimiento durante el funcionamiento.


Puntos clave del mantenimiento diario

Limpieza e inspección

Limpie diariamente la rejilla del separador y las bolsas filtrantes del recolector de polvo para evitar obstrucciones.

Verifique el estado de lubricación del transportador de rodillos transportadores y reponga o reemplace el aceite lubricante de manera oportuna.


Mantenimiento de componentes

Si las cuchillas delGranalladora con transportador de rodillosestán desgastados en más de la mitad de su espesor original o agrietados, deben ser reemplazados inmediatamente.

Compruebe periódicamente el rendimiento del sellado de los rodamientos para evitar fugas de aceite o desgaste causado por la vibración.


Mantenimiento periódico

Semanalmente: Inspeccione el estado de la tubería transportadora, las orugas de goma y las tiras de sellado, y reemplácelas si es necesario.


Mensualmente: Pruebe la velocidad de rotación de la granalladora (desviación ≤5%) y limpie el sistema hidráulico/neumático.

Cada trimestre: Calibrar el equilibrio delGranalladora con transportador de rodillosimpulsor e inspeccionar la deformación del soporte de la carcasa.


Prevención y manejo de fallas

Problemas comunes: atasco de proyectiles, sobrecalentamiento del motor, falla del sello.


Medidas de manipulación

Cuando la granalla está atascada, se debe detener la máquina para limpiar las impurezas en el silo y ajustar el grado de apertura de la válvula de suministro de granalla a ≤80%.


Cuando el motor se sobrecalienta, verifique el ventilador de enfriamiento y el estado de lubricación. Cada operación continua no debe exceder las 8 horas.
