Abstract

UN EQUIPO PARA LA REGULACION DE LA PRESION INICIAL DE UNA BOMBA (11) PRINCIPAL DISEÑADO COMO BOMBA REGULABLE DE UNA UNIDAD (10) DE COMPRESION QUE SUMINISTRA A UN CONSUMIDOR (54) HIDRAULICO QUE ESTA EQUIPADO CON UN REGULADOR (12) DE CAPACIDAD DE BOMBA CONTROLABLE POR MEDIO DE UN CILINDRO (13) DE REGULACION ACCIONADO MEDIANTE APLICACION ALTERNATIVA Y REDUCIENDO LA PRESION EN UNA CAMARA (18) DE ACCIONAMIENTO. UNA VALVULA (21) DE REGULACION DE PRESION PARA LA APLICACION Y DESCARGA DE LA PRESION ESTA ACCIONADA MEDIANTE LA PRESION INICIAL DE LA BOMBA Y POR ENCIMA DE UNA PRESION MINIMA DETERMINADA POR MEDIO DE UN RESORTE QUE SUMINISTRA UNA PRESION INICIAL QUE SE INCREMENTA CON UN CONTROL DE PRESION ACOPLADO DENTRO DE LA CAMARA (27) DE CONTROL. EL RESORTE (32) DE CONTROL DE RECUPERACION DE LA VALVULA (21) DE REGULACION DE PRESION SE AJUSTA A LA FUERZA DE RECUPERACION QUE CORRESPONDE SOLAMENTE A UNA FRACCION PEQUEÑA DE LA FUERZA DE CONTROL MAXIMO QUE PUEDE SER GENERADA POR MEDIO DE LA PRESION CONTROL. LA VALVULA (21) DE REGULACION DE PRESION ESTA PREVISTA CON UNA CAMARA (31) DE CONTROL ADICIONAL QUE, CUANDO SE APLICA LA PRESION, ES CAPAZ DE GENERAR UNA FUERZA DE RECUPERACION ADICIONAL CUYO VALOR MAXIMO CORRESPONDE AL MENOS DE FORMA APROXIMADA AL DE LA FUERZA DE CONTROL. LA PRESION ACOPLADA A LA CAMARA (31) DE RECUPERACION ES DERIVADA A PARTIR DE LA PRESION INICIAL DE LA BOMBA PRINCIPAL POR MEDIO DE UN RETARDADOR (36,34) HIDRAULICO.
