Chancadora de mandíbula es utilizado equipos de trituración en todos los ámbitos de la vida, para romper todo tipo de diferentes durezas, diferentes tipos de materiales, por lo que la Chancadora de mandíbula en el proceso de trabajo, es inevitable que se sobrecarga.Esto requiere que el propio equipo debe tener un buen sistema de autoprotección, para que la operación de dispositivos seguros, la tasa de fracaso se mantuvo en un nivel bajo.Una mandíbula Chancadora de sobrecarga de los métodos y el desarrollo de los comunes Condición machacadora de mandíbulas de trabajo es muy malo, la carga de trabajo volátiles, la carga máxima es por lo general más de tres veces la carga media.A menudo, debido a la desigual o porque la gente alimenta la cámara de trituración no se puede dividir en material resistente muy difícil (como el hierro, etc, en lo sucesivo, material de la barrera) y la sobrecarga repentina de un peligro considerable.Con este fin, más de protección contra sobrecargas machacadora de mandíbulas con medidas específicas, el desarrollo se ha utilizado principalmente los siguientes métodos. (1) soporte de romper la ley: la baja intensidad del soporte es fácil de establecer puntos de ruptura, que apareció en la sobrecarga de la Chancadora, la zona sensible debido a la tensión del soporte aumentó considerablemente a limitar el estrés en su propia para romper, cortar eltransmisión de energía, para evitar daños en la máquina. Esta medidas tradicionales de protección de sobrecarga, la estructura simple, fácil de fabricar.Sin embargo, debido a la placa codo (por lo general de hierro fundido) de las propiedades mecánicas de los volátiles y sujetos a la limitada precisión de los cálculos no se puede cuantificar con precisión los puntos de corte de control, la aplicación real es a menudo sobrecargados y la falta de protección.Además, incluso si la sobrecarga se ha protegido, pero a causa de las máquinas estropeadas en el estado de accidentes, la limpieza, desmontaje y piezas de repuesto antes de que la máquina no está funcionando, este proceso inevitablemente causa la interrupción, la producción de demora.(2) momento del volante de protección límite: El embrague de fricción primavera, embrague de fricción hidráulica o un alfiler de seguridad y así sucesivamente.Estos métodos en la Chancadora de mandíbula péndulo simple de aplicar más. Trituradora de quijada .Par de fricción del embrague de trabajo:Donde N es los resortes de disco y la fuerza de sujeción entre el embrague, f de los muelles y el disco de embrague entre el factor de fricción. Este embrague es necesario para asegurar la transmisión de par motor a trabajar, sino también la transferencia de par motor no exceda del valor admisible.Cuando la caída de materiales de la cámara de trituración de barrera, la sobrecarga de la máquina alcanza un par de críticas, el volante está libre para deslizarse en el eje de la UB, los principales componentes del efecto protector.Sin embargo, debido a la fricción del embrague / factor afectado por las condiciones externas (tales como la temperatura, etc) un mayor impacto a la fiabilidad de las restricciones, y la sobrecarga, todavía autorización humanos, dejar de reparar, la recuperación del sistema es demasiado problema. (3) protección hidráulica: como el ya mencionado dos tipos de métodos que existen para la protección de sobrecarga de protección en caso de accidente no es fiable y la necesidad de interrumpir el tratamiento, dando lugar a problemas de interrupción y el proceso de recuperación más difícil, con más material en la barrera de flujo del proceso de trituraciónmaterial (como la escoria de línea discontinua), son a menudo incapaces de satisfacer las necesidades de producción.Por lo tanto, el desarrollo del dispositivo de protección segura y fiable hidráulico para sustituir los medios tradicionales de protección pasiva como sea posible para asegurar un buen funcionamiento continuo de seguridad de la máquina es especialmente necesario.Molino de bola.

We had one of those UN boys temporary us the else day complaintive our regulations concerning the niggers.
