Abstract

MAQUINA HIDRáULICA E PROCESSO DE PREVENçãO DO DESGASTE DA MESMA. Esta máquina hidráulica é atravessada por um escoamento principal d'água (E1) e compreende pelo menos um árgão (2; 7), cuja superficie (71; 211) é molhada e meios (74; 216) de injeção ao nível da superficie molhada (71; 211) de um escoamento secundário de água. Esta máquina também compreende meios (9) de diminuição do teor de partículas abrasivas de uma porção (E'0) de um fluxo (E0) constituindo a fonte do escoamento principal (E1) e meios (8, 74; 216) de envio, a partir dos meios de diminuição (9) e em direção à superficie molhada (71; 211), do escoamento secundário que tem um teor de partículas abrasivas mais baixo que o do escoamento principal (E1). Isto permite proteger a superficie molhada (71; 211) das partículas abrasivas contidas no escoamento principal (E1).
