Abstract
EN UN GENERADOR DE PRESION HIDRAULICA CON UNA BOMBA PRINCIPAL ACCIONADA POR UN MOTOR DIESEL, UN CIRCUITO DE USUARIO PRINCIPAL CONECTADO A LA BOMBA, ESTA FORMADO POR UNA BOBINA DE AJUSTE (18) CONECTADA DIRECTAMENTE A LA BOMBA PRINCIPAL Y POR UN USUARIO (11) CONECTADO EN SERIE A LA BOBINA. POR COMPARACION DE LA PRESION DE SALIDA PH ACOPLADA EN UNA PRIMERA CAMARA DE CONTROL DE UNA VALVULA DE CONTROL (31) CON LA PRESION DE COMPARACION PV QUE PUEDE SER DETECTADA EN EL USUARIO PRINCIPAL (11) Y ACOPLADA EN UNA SEGUNDA CAMARA DE CONTROL (37) DE LA VALVULA DE CONTROL (31), LA VALVULA DE CONTROL (31) CONTROLA UN DISPOSITIVO DE AJUSTE (21,22) DE TAL FORMA QUE EL VOLUMEN DE FLUJO EN EL CIRCUITO DE USUARIO PRINCIPAL (16,11) PERMANECE CONSTANTE. UN DISPOSITIVO PROTECTOR DISEÑADO PARA PREVENIR QUE EL MOTOR DIESEL (13) SE CALE BAJO CARGA EXTREMA, COMPRENDE UNA BOMBA AUXILIAR (42) ACCIONADA POR EL MOTOR DIESEL, LA CUAL GENERA UN VOLUMEN DE FLUJO DE SALIDA PROPORCIONAL A LA VELOCIDAD DE ROTACION QUE PASA POROTRA BOBINA DE AJUSTE (46) Y POR UN USUARIO (44) SINCRONIZADO EN REVOLUCIONES CONECTADO A CONTINUACION, ASI COMO POR UNA VALVULA CONTROLADA POR LA PRESION (47), POR MEDIO DE LA CUAL LA SEGUNDA CAMARA DE CONTROL (37) DE LA VALVULA DE REGULACION (31) DESCARGA PRESION HACIA EL TANQUE (32) Y DE ESE MODO AJUSTA LA BOMBA PRINCIPAL (12) AL VOLUMEN DE IMPULSION MINIMO, CUANDO EL NUMERO DE REVOLUCIONES DEL MOTOR HA DESCENDIDO POR DEBAJO DE UN VALOR UMBRAL.
