Abstract
resumo método para detectar e isolar um vazamento em um sistema hidráulico, meio de armazenamento legível por computador e sistema hidráulico é divulgado um método para a detecção e isolamento de um vazamento em um sistema hidráulico tendo uma bomba de alimentação servindo pelo menos uma válvula de controle. em uma concretização, a válvula de controle tem várias seções de trabalho. na etapa do método, o sistema hidráulico é ativado. em outra etapa, é recebido um comando de acionamento para pelo menos uma das seções de trabalho, por exemplo, a partir de uma interface homem-máquina. subsequentemente, o método pode incluir a geração de uma demanda de fluxo para as seções de trabalho para as quais um comando de acionamento foi recebido. o método também inclui a etapa de implementação em pelo menos um de um primeiro, segundo, terceiro, e quarto protocolos de detecção e isolamento de vazamento para detectar e isolar um vazamento entre a bomba e o arranjo de válvula de controle, um vazamento entre o reservatório e o arranjo de válvula de controle, e um vazamento entre pelo menos um circuito de trabalho e o arranjo de válvula de controle.
