Abstract
resumo método e aparelho para desativar um dispostivo hidráulico que esteja vazando óleo hidráulico um método de desativar um dispositivo hidráulico subaquático proporciona um dispositivo hidráulico, que é capaz de ser operado debaixo de água, o dispositivo tem um cilindro hidráulico com um impulsor e um pistão. o dispositivo é reduzido abaixo de uma superfície de água, com uma bobina de tubo flexível, que está localizado na área de superfície de água, tal como em uma embarcação marítima. o carretel da mangueira inclui primeiro e segundo tubos hidráulicos que conectam ao cilindro em lados opostos do pistão. o fluxo de fluido na primeira e na segunda mangueira hidráulicas é monitorizado continuamente. a proporção entre o volume de fluido que flui para dentro do cilindro a partir de um lado do êmbolo para o volume de fluido que flui para dentro do cilindro a partir do outro lado do cilindro é continuamente calculado com um computador ou controlador. o dispositivo hidráulico é desativado se a proporção varia de um valor pré-determinado. uma forma de realização inclui uma pluralidade de medidores de fluxo para medir o fluxo de fluido para e a partir de um ou mais aparelhos acionados hidraulicamente. em uma forma de realização saídas dos medidores de fluxo são analisados para determinar se o sistema hidráulico tem um vazamento, e se é detectada uma fuga, é emitido um aviso e / ou um ou mais dos aparelhos acionados hidraulicamente ligados são desligados, e / ou o fornecimento de energia hidráulica é desligado.
