[39] Hydraulic power unit: Reservoir
The hydraulic reservoir
contains the hydraulic fluid required the operate the
installation. Within the reservoir, air, water and solid matter
are separated out of the hydraulic fluid.
The size of the reservoir will depend on the practical application involved; for stationary systems, the volume of fluid delivered by the pump in 3 to 5 minutes can be taken as a guide. In mobile hydraulic systems, on the other hand, the reservoir contains only the maximum quantity of hydraulic fluid required.
