Descripci\u00f3n<\/td>\n\u00a0<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Secuencia 32
Presi\u00f3n nominal cuatrocientos bar
Fuerza m\u00e1xima 450
Sistema de control: NV, HD3, HW, DG, DA1, DA2, EP3, EP4, EZ1, EZ2
\u00a0
La bomba variable de pistones axiales A4VG en estilo de placa oscilante para transmisiones hidrost\u00e1ticas de circuito cerrado
\u2013 La corriente es proporcional para generar velocidad y desplazamiento y es infinitamente variable
\u2013 La circulaci\u00f3n de salida aumentar\u00e1 con el \u00e1ngulo de giro del plato oscilante desde su valor m\u00e1ximo.
\u2013 La trayectoria de movimiento se modifica f\u00e1cilmente cuando el plato oscilante se mueve a trav\u00e9s de la posici\u00f3n neutra
\u2013 Se ofrece una amplia gama de dispositivos de control muy adaptables para distintas funciones de control y regulaci\u00f3n.
\u2013 La bomba est\u00e1 equipada con dos v\u00e1lvulas de ayuda de presi\u00f3n en los puertos de fuerza sustancial para proteger la transmisi\u00f3n hidrost\u00e1tica (bomba y motor) contra sobrecargas.
\u2013 Las v\u00e1lvulas reductoras de mayor fuerza tambi\u00e9n funcionan como v\u00e1lvulas de mejora.
\u2013 La bomba de refuerzo integrada funciona como bomba de aceite de alimentaci\u00f3n y control.
\u2013 La tensi\u00f3n de aumento \u00f3ptima est\u00e1 limitada por una v\u00e1lvula de reducci\u00f3n de tensi\u00f3n mejorada incorporada
\u2013 El corte de tensi\u00f3n integral es CZPT<\/p>\n
