Yuken Hydraulic Variable Displacement Piston Pump A3H A10 A3H56 Series A3H56-FR01KK A10-FR01C-12 For Machineries
Safety Valve
When delivery line is blocked suddenly, surge pressure is
occurred so a safety valve should be set in the circuit to
eliminate any damage on equipment and piping.
Bleeding Air
It may be necessary to bleed air from pump case and outlet
line to remove causes of vibration.
Starting
Before first staring, fill pump case with clean operating
oil via the fill port.
In order to avoid air blockage when first starting, adjust
the control valves so that the discharged oil from the pump
is returned direct to the tank or the actuator moves in a
free load
