Abstract [sv]

Utgångspunkten för detta examensarbete var att testa om en ny hydraulolja, kandidatolja, har bättre verkningsgrad i hydrauliska system jämfört med en idag använd hydraulolja som referens. För ändamålet skulle en testrigg konstrueras och byggas. Därvid skulle om möjligt befintliga komponenter och mätsystem som fanns användas. Som underlag för konstruktionsarbetet gjordes en grundlig förstudie gällande konstruktion av hydrauliska system i allmänhet, komponenter och adekvat hydraulisk teori.Under arbetets gång blev det uppenbart att det skulle vara tid- och resurskrävande att konstruera och bygga en rigg att mätningar näppeligen skulle hinna utföras inom examensarbetets tidsram. Arbetet riktades istället in på att använda en färdig utrustning som efter modifikationer kunde användas för ändamålet. En sådan utrustning fanns på ITH i Örnsköldsvik.Efter överenskommelse med ITH utfördes mätningarna av författaren till denna rapport tillsammans med tekniker på plats i Örnsköldsvik. Kandidat- och referensoljan testades vid 100, 200 och 300 bar och mätdata samplades kontinuerligt.Insamlad mätdata analyserades och gav som resultat att kandidatoljan ger marginellt förbättrade värden vad avser verkningsgrad än referensoljan.

Abstract [en]

The aim of this master thesis was to test if a new hydraulic oil, candidate oil, has better efficiency in a hydraulic system compared to a commonly used hydraulic oil as reference. For this purpose a test rig was going to be designed and built. Existing components and measurement equipments at KTH would be used. As a basis for the design, a thorough pre-study was made regarding design of hydraulic systems in general, components and adequate hydraulic theory.As the work progressed it became apparent that it would be so time consuming and resource-demanding to design and build a test rig that there would be very little time to perform the tests, within the timeframe of the thesis. The work was instead focused on finding a suitable complete tests rig which after smaller modifications could be used for the efficiency tests. Such a test rig was eventually found at ITH in Örnsköldsvik.In agreement with ITH the measurements were performed by the author of this report, together with a technician on-site in Örnsköldvik. Candidate and reference oil were tested at 100, 200 and 300 bars and data was sampled continuously.The collected data was evaluated and it was shown that the candidate oil gives marginally improved values concerning the efficiency
