System och förfarande för viskositetsreglering av vätska |
摘要 |
The invention relates to a method and system for controlling viscosity of a hydraulic fluid. The viscosity of a hydraulic fluid is usually very much dependent on temperature. By using existing throttles which generate a pressure drop, the hydraulic fluid can be heated by creating a power drain in these existing throttles through a controlled increase of the pressure through them. By controlled heating, the viscosity of a hydraulic fluid can be controlled. According to the invention, the existing throttles are preferably cavity-preventing openings in valves. |
