Abstract

System dostarczania płynu dla kombajnu ścianowego przedstawionego na rysunku. System dostarczania płynu zawiera urządzenie do sterowania przepływem oraz procesor elektroniczny. Urządzenie do sterowania przepływem jest połączone przepływowo z dyszą umieszczoną na kombajnie, a także połączone przepływowo ze źródłem płynu. Procesor elektroniczny jest sprzężony z urządzeniem do sterowania przepływem. Procesor elektroniczny jest skonfigurowany do odbierania pomiaru parametru wydajności, a także określania modelowego przepływu płynu w oparciu o pomiar parametru wydajności. Parametr wydajności odpowiada położeniu kombajnu wzdłuż czoła przodka. Procesor elektroniczny jest ponadto skonfigurowany do ustalania parametru operacyjnego urządzenia do sterowania przepływem w oparciu o modelowy przepływ płynu, a także obsługi urządzenia do sterowania przepływem zgodnie z ustalonym parametrem operacyjnym.
