Abstract
SE PRESENTAN SISTEMAS AUTOMATICOS PARA LA LIMPIEZA DE PISCINAS. LOS SISTEMAS INCLUYEN UN LIMPIADOR AUTOMATICO DE PISCINAS (10) QUE INCORPORAN UNO O MAS DISPOSITIVOS CURVADOS (30) QUE SOBRESALEN DE SU SUPERFICIE INFERIOR. LOS DISPOSITIVOS DE LIMPIEZA (30) Y EL FONDO PLANO (34) DEL LIMPIADOR (10) INDUCEN UN REMOLINO A MEDIDA QUE EL FLUIDO FLUYE HACIA SU ENTRADA CENTRAL (50) INTRODUCIENDO LOS DESECHOS EN EL FLUJO. UN CUELLO ACANALADO (102A) QUE RODEA LA ENTRADA (50) AYUDA ADICIONALMENTE PARA QUE EL INTERIOR DE LA BASE DEL LIMPIADOR RETENGA LOS DESECHOS CUANDO SE ABRE PARA LA LIMPIEZA, SUMINISTRANDO ADICIONALMENTE UNA TRAYECTORIA MEJORADA PARA EL FLUJO PARA LA MEJOR RECOGIDA DE LOS DESECHOS. TAMBIEN SE PRESENTA UNA VALVULA (200) UTIL PARA CONTROLAR E INDICAR LA VELOCIDAD DEL FLUJO DEL FLUIDO HACIA UN LIMPIADOR (10). INCLUIDO DENTRO DE LA VALVULA SE ENCUENTRA UN EMBOLO (203) SUJETO A UN MUELLE (202), OPONIENDOSE LA FUERZA DEL MUELLE AL FLUJO DEL FLUIDO A TRAVES DE LA VALVULA (200). EL FLUJO SUFICIENTE PARA VENCER LA FUERZA DEL MUELLE COMPRIME EL MUELLE (202), MOVIENDO DE ESTA FORMA EL EMBOLO (203) DENTRO DEL TUBO (201) Y SUMINISTRANDO UNA INDICACION DINAMICA DE LA VELOCIDAD DEL FLUJO DEL FLUIDO. UN DIFUSOR (206) Y PUERTOS DE LIBERACION DEL FLUIDO (204) PERMITE QUE LA VALVULA SE AJUSTE PARA CONSEGUIR UNA VELOCIDAD DE FLUJO DESEADA.
