Abstract

CONJUNTO DE CONTROLE DE BOMBA E MÉTODO PARA ATUAR UM CONJUNTO DE CONTROLE DE BOMBA. Um conjunto de controle de bomba inclui um conjunto de bomba de fluido (12) tendo uma bomba de fluido (20) e uma válvula de detecção de carga. A bomba de fluido inclui uma entrada de fluido (24) e uma saída de fluido (26). A bomba de fluido inclui um mecanismo de deslocamento variável (36). A válvula de detecção de carga (42) está adaptada para ajustar a posição do mecanismo de deslocamento variável. A válvula de detecção de carga inclui uma primeira extremidade (46) e uma segunda extremidade disposta opostamente (48). Um atuador (60) está em comunicação fluida com o conjunto de bomba de fluido. Um sensor de posição (100) monitora a posição do atuador. Uma válvula de alteração (110) provê comunicação fluida seletiva entre a saída de fluido da bomba de fluido e a primeira extremidade da válvula de detecção de carga. Uma unidade de controle eletrônico está em comunicação elétrica com o sensor de posição e a válvula de alteração. A unidade de controle eletrônico transmite uma corrente de saída para a válvula de alteração em resposta à posição do atuador.
