Vökvakerfið eyðir miklu olíu

Due to the large change in the output power of the hydraulic press system, the flow and pressure requirements are different in different processes, and it is necessary to rely on the flow valve and pressure valve to adjust the required flow and pressure, but the quantitative pump does not have an adjustment function, and the energy is wasted when the oil temperature rises, and it also increases the wear of each valve, the oil temperature is high and the noise is large, which will shorten the overall use time of 400- tonn fjögurra dálka vökvapressu .
