| 摘要 |
The invention relates to a method for adjusting supply pressure (ps) in a hydraulic system. The method comprises a feeder pump (23) for producing the supply pressure (ps), at least two hydraulic actuators (8a, 8b, 8c), measuring means for measuring the pressure levels of the actuators (8a, 8b, 8c), and a pressurized medium flow channel system. In the method, it is examined, in which actuators (8a, 8b, 8c) the load pressure is caused by moving a load (positive work). From the pressure levels of the actuators (8a, 8b, 8c) performing load-moving work, the highest is selected, and the supply pressure (ps) is adjusted on the basis of the selected pressure level. |
