Abstract
UN APARATO HIDRONEUMATICO CONTROLA EL FUNCIONAMIENTO DE UNA BOMBA DE MOTOR ELECTRICA QUE SUMINISTRA AGUA PRESURIZADA U OTRO LIQUIDO, SEGUN UNA DEMANDA DE CONSUMO VARIABLE. EL APARATO INCLUYE UN DISPOSITIVO SENSOR DE CORRIENTE QUE DETECTA LA VARIACION EN LA DEMANDA DE CONSUMO. EL DISPOSITIVO SENSOR DE CORRIENTE TIENE UN PISTON DE CONDUCCION COLOCADO DENTRO DE UNA CAMARA DE TRANSFERENCIA DE PRESION QUE ESTA COMUNICADA CON UN CONMUTADOR DE PRESION CONECTADO ELECTRICAMENTE A LA BOMBA DE MOTOR. LA CAMARA DE TRANSFERENCIA DE PRESION ESTA TAMBIEN COMUNICADA PERMANENTEMENTE A LA PRESION DEL AGUA. UN TANQUE HIDRONEUMATICO CUENTA CON UN DISPOSITIVO DE TRANSFERENCIA QUE PERMITE LA ENTRADA DE AGUA AL TANQUE, PERO LIMITA LA CORRIENTE DE SALIDA DESDE EL.
