Chapter 9 Design of Hydraulic Transmission systems 9.1.4 calculation and selection of hydraulic components 1.Selection of pumps According to maximum working pressure and provided flow rate calculated above,a proper pump can be selected from product samples.For the sake of safety,the chosen pump must be with a rated pressure 20%60% higher than the maximum working pressure(described above)for pressure reserve,but with a rated flow rate just meeting the maximum flow rate to avoid an exceeding loss of power. 2.Selection of valves Homepage List Upwards Downwards Retumn Exit Chapter 9 Design of Hydraulic Transmission systems 14 9.1.4 calculation and selection of hydraulic components 1. Selection of pumps According to maximum working pressure and provided flow rate calculated above, a proper pump can be selected from product samples. For the sake of safety, the chosen pump must be with a rated pressure 20%~60% higher than the maximum working pressure (described above) for pressure reserve , but with a rated flow rate just meeting the maximum flow rate to avoid an exceeding loss of power. 2.
