Abstract
Disc stack centrifugal separator is technology used for separating two different density liquids or purifying liquid by removing solid particles that it contains. Feed system prepares and delivers dirty oil to the separator. Separation process takes place within bowl assembly where lighter liquid flows out through the inner and water through outer edge outlet with sludge building up on the bowl side. Once the timer runs out or the control unit detects water in clean liquid outlet, sludge discharge is initiated by means of hydraulic mechanism located beneath the bowl. Power and transmission unit provides torque for bowl rotation so that strong centrifugal field is created. PLC based control unit ensures automatic operation and constantly monitors operation parameters. If their value crosses threshold, alarm is sounded which is indication of potential fault. By applying fault diagnosis methods, and with aid of fault detection system, engine officer can isolate the fault and find remedy so that purification system can be restored to normal operation.
Abstract (croatian)
Centrifugalni separator je tehnologija koja se koristi za odvajanje dviju tekućina različitih gustoća odnosno pročišćavanje tekućine koja sadrži krute čestice. Dobavni sustav priprema i dovodi neobrađeno ulje/gorivo u separator. Proces odvajanja vrši se unutar bubnja na površini sloga tanjura gdje lakša tekućina izlazi preko unutarnjeg, a voda preko vanjskog ruba, dok se talog zadržava na stijenkama bubnja. U trenutku kada brojač istekne ili kontrolna jedinica registrira vodu u pročišćenom ulju, izbacivanje taloga se ostvari putem hidrauličke jedinice koja se nalazi ispod bubnja. Pogonska jedinica osigurava okretni moment kojim se bubanj rotira, time stvarajući snažno centrifugalno polje unutar bubnja. Kontrolna jedinica bazirana na PLC-u osigurava automatsku operaciju uz konstantno praćenje radnih parametara. Ako njihova vrijednost prijeđe dozvoljenu granicu, alarm se uključuje koji je indikacija potencijalnog kvara. Primjenjujući metode dijagnostike, te uz pomoć sustava detekcije kvarova, časnik stroja može izolirati i otkloniti kvar kako bi vratio separatorski sustav u normalno stanje.
