Chapter 6 Auxiliary Components for Hydraulic Systems 2.Discharging out oil fluid(release) When the system pressure is lower than the pressure of the operating oil,the interlay is moved down under the action of gas pressure(or weight loaded or spring loaded);at the same time oil is discharged out of the accumulator and flows into the system until a new pressure equilibrium on the two sides of the interlayer as shown in Fig.6-2c. 6.1.2 Applications Such an accumulator can be used to advantage in a number of hydraulic applications: 1)To supply oil lost through leakage in a system held under pressure but not operating for long periods.To serve as an auxiliary or emergency source of hydraulic power where pump Homepage List Upwards Downward达 Return ExitChapter 6 Auxiliary Components for Hydraulic Systems 7 2.
