Abstract
En i det vesentlige konstant viskositet for en væskeblanding ved en gitt temperatur opprettholdes ved blanding av to væsker med forskjellige viskositeter, særlig dieselolje og tung brenselsolje for til-førsel til en motor. Væskeblandingen som konstant fremstilles i en blandeinnretning (12) føres gjennom en oppvarmingsinnretning (2 3) . Viskositeten for den oppvarmede blanding måles i et viskosimeter (30) beregnet for å regulere oppvarmingen slik at en i det vesentlige konstant viskositet opprettholdes. Videre måles temperaturen for den oppvarmede blanding og ^ blandingsforholdet mellom begge væsker reguleres i samsvar med temperaturen, slik at temperaturen holdes i det vesentlige konstant.•).
Description
Oppfinnelsen vedrører en fremgangsmåte og et apparat for blanding av to væsker med forskjellige viskositeter, mens det opprettholdes i det vesentlige konstant viskositet ved en gitt temperatur for væskeblandingen. Oppfinnelsen ved-rører spesielt blanding av oljer med forskjellig viskositet, og fremfor alt blanding av dieselolje med tung brenselolje for tilførsel til motorer, f.eks. hjelpemotorer på fartøyer.
Med de økende oljepriser er det blitt mer og mer vesentlig å redusere brenselkostnadene for drift av slike hjelpemotorer på fartøyer, som vanligvis drives på dieselolje. Til dette formål er det blitt foreslått å blande lavkvalitets-oljer (tunge brenseloljer) med dieselolje for tilførsel til slike motorer. Da disse motorer krever en olje med en spesi-ell viskositet ved en gitt temperatur for deres drift, må det være sikret at blandingsforholdet reguleres på en slik måte at den egnede viskositet opprettholdes. Til dette formål er det blitt foreslått et system i hvilket ulandingsforholdet reguleres ved bestemmelse av temperaturen og viskositeten for blandingen. De målte verdier tilførs til en beregningsenhet som omdanner den målte viskositetsverdi til en verdi som er egnet ved den ønskede temperatur, og med leding heri fast-settes blandingsforholdet, f.eks. ved å regulere arbeidet til to pumper som mater blandingen med begge oljer, slik at en i det vesentlige konstant viskositet ved den ønskede temperatur opprettholdes.
Dette system har den ulempe at den nødvendige beregningsenhet er en dyr komponent. Videre krever systemet bruk av blandetanker. Det er ikke mulig å blande de to oljer direkte i en ledning som fører til motoren.
Den foreliggende oppfinnelse har ti] hensikt å eliminere disse ulemper ved tilveiebringelse av en fremgangsmåte og et apparat ved hvilket blandetrinnet kan gjennomføres underveis uten å kreve bruk av en dyr beregningsenhet.
Dette er ifølge den foreliggende oppfinnelse opp-nådd ved hjelp av de karakteristiske trekk som angitt i karakteristikken til det etterfølgende selvstendige krav 1, nemlig: at blandingen med et bestemt blandingsforhold oppvarmes, at dens temperatur og viskositet etter oppvarming måles, at oppvarmingen reguleres med rettledning i den således bestemte viskositet, at en i det vesentlige konstant viskositetsverdi etter oppvarmingen opprettholdes og at blandingsforholdet mellom begge væsker reguleres deretter med rettledning fra den målte temperatur, slik at en i det vesentlige konstant temperatur for væskeblandingen opprettholdes etter oppvarmingen.
Oppfinnelsen er beskrevet i detalj under henvisning til tegningen, som skjematisk illustrerer et apparat for gjen-nomføring av fremgangsmåten for blanding av dieselolje og tung brenselsolje for tilførsel til en motor.
Apparatet innbefatter en dieseloljepumpe 1, som på sin sugeside er forbundet via en ledning 2 til en dieselolje-tank, en ledning 3 med en enveisventil 4 som går ut fra dens trykkside og en tungoljepumpe 5, som på sin sugeside er forbundet via en ledning 6 til en tung brenselsoljetank og en ledning 7. med en enveisventil 8 som går ut fra dens trykkside. Dieseloljepumpen 1 drives av en motor 9 med en variabel rotasjonshastighet, og den tunge oljepumpe 5 drives av en motor 10 med en konstant rotasjonshastighet.
Begge ledninger 3, 7 føres til en ledning 11 som åpner i en blandeinnretning 12 i hvilken dieseloljen og den tunge brenselsolje blir blandet. Blandingen føres ut via en ledning 13, fra hvilken en returledning 14 med enveisventilen 15 fører til ledningen 6 på sugesiden av pumpen 5, slik at en del av oljeblandingen føres tilbake til pumpen 5, hvilken pumpe således drives med en blanding av ny tilført tung brenselsolje og oljeblanding som allerede er produsert.
Delen av oljeblandingen som ikke resirkuleres strømmer først gjennom en "strømningsmåler 16. Blandingen blir så transportert via en ledning 21 av en pumpe 22 for å
ta blandingen gjennom en oppvarmingsinnretning 23. Blandingen som strømmer fra oppvarmingsinnretningen 23 passerer gjennom en ledning 28. I denne ledning blir temperaturen for blandingen målt av et termometer 29 og viskositeten ved hjelp av et viskosimeter 30. Blandingen blir så ført via et filter 31 til punktet'for forbruk, dvs. en dieselmotor (ikke vist) via en ledning 32.
I det illustrerte eksempel blir oljeblandingen opp-varmet i oppvarmingsinnretningen 23 ved hjelp av damp som til-føres via en ledning 33, mens kondensatet tas ut via en ledning 34. En variabel innsnevring 35 er innsatt i ledningen 33, og dens innstilling reguleres av viskosimeteret 30, som angitt med linjen 36. Temperaturen som avleses av termometeret 29 tjener for innstilling av den variable motor 9, som antydet med linjen 37.
Systemet drives på følgende måte: Hvis blandings-viskositeten ved viskosimeteret 30 har en tendens til å øke, sendes et signal som øker damptilførselen ved innsnevringen 35, hvorved oppvarming i oppvarmingsinnretningen 23 øker, og temperaturen som avleses av termometeret 29 øker. Et signal blir derved gitt til motoren 9, som får øket sin rotasjonshastighet, slik at pumpen tilfører en større mengde dieselolje, og blandingens viskositet reduseres. Hvis istedet viskositeten ved viskosimeteret 30 har en tendens til å avta, blir damptilførselen til oppvarmingsinnretningen 2 3 begrenset, hvorved temperaturen som avleses av termometeret 29 faller og motoren 9 bringes til å drives ved en lavere rotasjonshastighet, slik at tilsetningen av dieselolje avtar. Således føres en blanding med i det vesentlige konstant viskositet og i det vesentlige konstant temperatur til motoren.
En ledning 38 opptar tilbakeført oljeblanding fra dieselmotoren som blir tilført via en enveisventil 39 og en lufteventil 40 til sugesiden av pumpen 22.
En ledning 41 med enveisventilen 42 fører fra ledningen 2 direkte til ledningen 21. Dette gjør det mulig å tilføre motoren:bare dieselolje hvis nødvendig, f. eks. i til-felle av forstyrrelser i blandesystemet.
