Claims (14)
1. System for kjøling og barrierefluid (7, 12, 17) for en undersjøisk motor og pumpe eller kompressor-sammenstilling (1, 2) som omfatter en motor (1) som er drivbart koblet til en pumpe- eller kompressorrotor (2), idet motoren er utstyrt med en elektronisk drivenhet (8) som omfatter elektroniske og/eller mekaniske komponenter som regulerer tilførselen av elektrisk kraft til motoren, og idet barrierefluid blir tilført systemet fra en barrierefluidkilde på overflaten eller nedsenket under et trykk som tjener til å skille motoren fra et fluid som blir prosessert av pumpen eller kompressoren under drift,karakterisert vedat systemet for kjøling og barrierefluid (7, 12, 17) omfatter en sløyfe (17) for barrierefluidstrøm som er forlenget til den elektroniske drivenheten (8) og som tilfører barrierefluid gjennom den elektroniske drivenheten (8).
2. System for kjøling og barrierefluid i henhold til krav 1, idet sløyfen (17) for barrierefluidstrøm omfatter en passasje gjennom et kjøleelement (10) som tjener til kjøling av en komponent (9) i den elektroniske drivenheten (8).
3. System for kjøling og barrierefluid i henhold til krav 1 eller 2, som omfatter en kjølekrets (12, 13) innrettet eksternt i forhold til et motorhus (14) som kapsler inn motoren, idet en gren av kjølekretsen er forlenget til et drivenhetshus (11) som omslutter komponentene (9) i den elektroniske drivenheten (8).
System for kjøling og barrierefluid i henhold til krav 3, idet den elektroniske
drivenheten (8) regulerer tilførselen av kraft til motoren (1) via et grensesnitt (20) mellom husene på de sammenkoblede motor- og drivenhetene (14, 11). 5. System for kjøling og barrierefluid i henhold til hvilket som helst foregående krav, idet separate innkapslinger av pumpe/motor og drivenhet er koblet sammen ved barrierefluidrør og elektriske kabler. 5. Integrert drivmotor-og-pumpe/kompressor-sammenstilling (1, 2, 8) som omfatter et system for kjøling og barrierefluid (7, 12, 17) i henhold til hvilket som helst av kravene 1-5. 7. Drivmotor-og-pumpe/kompressor-sammenstilling (1, 2, 8) i henhold til krav 6, som omfatter termisk atskilte kjølesløyfer (13, 13") for henholdsvis drivenheten (8) og motoren (1). 8. Drivmotor-og-pumpe/kompressor-sammenstilling (1, 2, 8) i henhold til krav 5-7, idet en skillevegg (21) i motorrommet (3) deler barrierefluidet i et første og et andre volum som kommuniserer via et smalt gap eller tetning (22) rundt motorakselen (6). 9. Drivmotor-og-pumpe/kompressor-sammenstilling (1, 2, 8) i henhold til krav 5-8, som omfatter individuelle impellere (18, 18") innrettet til å bli drevet i rotasjon av motorakselen (6) for å utvirke sirkulasjon av barrierefluid i de separate kjølesløyfene (13, 13<5>). 10. Fremgangsmåte for å avkjøle komponenter (9) i en elektronisk drivenhet (8) som er innrettet for å regulere tilførsel av elektrisk kraft til en motor i en undersjøisk sammenstilling (1, 2) av motor og pumpe eller kompressor, som omfatter en motor (1) innrettet til å være drivbart koblet til en pumpe- eller kompressorrotor (2), idet et system (7, 12, 17) for kjølemiddel og barrierefluid er innrettet og virksomt for å atskille motoren fra et fluid prosessert av pumpen eller kompressoren som er i drift, idet fremgangsmåten erkarakterisert vedtilførsel av barrierefluid fra barrierefluidsystemet gjennom den elektroniske drivenheten (8). 11. Fremgangsmåte i henhold til krav 10, som omfatter tilførsel av barrierefluid gjennom et kjøleelement (10) som tjener til kjøling av komponenter (9) i den elektroniske drivenheten (8). 12. Fremgangsmåte i henhold til krav 10 eller 11, som omfatter kjøling av barrierefluider eksternt i forhold til motor- og pumpe-sammenstilling eller kompressor-sammenstilling (1, 2) i en kjølekrets (12, 13) som er forlenget til å sende barrierefluid gjennom drivenheten (8). 13. Fremgangsmåte i henhold til hvilket som helst av kravene 10-12, som omfatter regulering av krafttilførsel til motoren (1) via et grensesnitt (18) mellom sammenkoblede motor- og drivenhet-hus (14, 11). 14.Fremgangsmåte i henhold til krav 12, idet drivenhet-huset (11) er fylt med
isolasjonsolje under trykk eller fylt med gass til om lag atmosfærisk trykk.
