    Sammanfattning : Moving parts cause vibrations and tend to wear out. In applications where maintenance is complicated, solutions without moving parts are therefore advantageous. Electrohydrodynamic pumps are such a solution. Instead of mechanical propulsion, they use strong electric fields to induce movement in a dielectric cooling liquid. LÄS MER

  3. 2. Package Concept for High Variation Products to Improve Production : Package Development and Implementation to Improve Production of Heavy and High Variation Products

    Master-uppsats, Linköpings universitet/Produktrealisering

    Författare :Oliver Hjertstedt Otterström; [2023]

    Nyckelord :;

    Sammanfattning : In Sweden, district heating is the most common way to heat apartment buildings and premises. It is most common for properties to use district heating as the only heating source, but there are now trends in which more and more properties combine district heating with another energy source such as an exhaust air heat pump or geothermal heating.

  7. 5. CONTROL STRATEGY AND MODELING FOR ENGINE OIL SYSTEM

    Master-uppsats, Mälardalens högskola/Akademin för innovation, design och teknik

    Författare :Dalibor Colic; Jakob Norin; [2021]
    Nyckelord :;

    Sammanfattning : The power of an engine is not only used to drive the mechanical equipment connected to the engine, but also parts of the engine itself. One of these parts is the oil pump. The minimum needed oil pressure, produced by the pump, varies during the operational run of the engine. LÄS MER
