El caudal llena una c\u00e1mara, por lo que ese mismo caudal hace que una c\u00e1mara de menor superficie se mueva m\u00e1s r\u00e1pido. Por eso, un cilindro convencional de un solo v\u00e1stago y doble efecto suele retraerse m\u00e1s r\u00e1pido de lo que se extiende cuando se aplica el mismo caudal en ambas direcciones.<\/p>\n<h2>Utiliza el \u00e1rea correcta para cada direcci\u00f3n<\/h2>\n<p>Durante la extensi\u00f3n, el aceite que entra llena la c\u00e1mara del extremo de la tapa y act\u00faa sobre toda la superficie del pist\u00f3n. Durante la retracci\u00f3n, el aceite llena la c\u00e1mara del extremo del v\u00e1stago y act\u00faa sobre la superficie anular tras restar la secci\u00f3n transversal del v\u00e1stago. La diferencia de superficie modifica tanto la velocidad como la fuerza disponible. Un v\u00e1stago m\u00e1s grande aumenta la diferencia de velocidad, pero tambi\u00e9n altera el equilibrio de fuerzas y los vol\u00famenes de aceite que debe gestionar el circuito.<\/p>\n<h2>Un ejemplo sencillo<\/h2>\n<p>Para un di\u00e1metro interior de 100 mm, el \u00e1rea del extremo del casquillo es de unos 7.854 mm\u00b2. Un caudal de 30 L\/min equivale a 500.000 mm\u00b3\/s. Al dividir el caudal por el \u00e1rea se obtiene una velocidad de extensi\u00f3n ideal de unos 64 mm\/s. El tiempo correspondiente para una carrera de 500 mm ser\u00eda de unos 7,9 segundos con un caudal constante. Los tiempos reales pueden variar debido a que el caudal de la bomba, el dosificado de las v\u00e1lvulas, las fugas y la carga var\u00edan a lo largo del ciclo.<\/p>\n<h2>\u00bfQu\u00e9 factores influyen en la velocidad de una m\u00e1quina real?<\/h2>\n<p>Una v\u00e1lvula de control de caudal puede dosificar el movimiento, mientras que una bomba variable puede modificar el caudal disponible. Las mangueras largas y los orificios peque\u00f1os provocan p\u00e9rdidas de presi\u00f3n. La temperatura afecta a la viscosidad del aceite; una carga puede acelerar o frenar el movimiento. Al final de la carrera, un amortiguador puede ralentizar deliberadamente el pist\u00f3n. En m\u00e1quinas con varios actuadores, el caudal disponible de la bomba puede repartirse. Mide la velocidad en el cilindro y la funci\u00f3n, ya que la geometr\u00eda de la articulaci\u00f3n puede hacer que la velocidad de la herramienta difiera de la velocidad del v\u00e1stago.<\/p>\n<h2>Especificar un perfil de movimiento<\/h2>\n<p>Se deben indicar las velocidades de aproximaci\u00f3n, trabajo, retorno y final de carrera, en lugar de una \u00fanica cifra correspondiente al tiempo de ciclo. Se deben incluir los requisitos relativos a la carrera, la carga, la presi\u00f3n, el caudal y el control. Las plataformas elevadoras y otros equipos m\u00f3viles tambi\u00e9n requieren una revisi\u00f3n de seguridad a nivel de la m\u00e1quina.
