Hydraulic Variable Displacement Piston Pump Yuken A3H Series A3H56-LR09KK-10 For Injection Molding Machines

Hydraulic Variable Displacement Piston Pump Yuken A3H Series A3H56-LR09KK-10 for Injection Molding Machines 2. The inlet and outlet of the oil pump must be loaded with combined gaskets, and the pipe joint must be sealed well. Replace clean hydraulic oil and oil suction filter screen, so as to avoid running air. 3, injection of oil, pipeline all connected, to the first pressure regulating valve to the lowest, idling for 10 minutes and then began to slowly raise the pressure to 5 mpa 5 minutes, 5 minutes later to lift the required working pressure, so that the residual air displacement in the pump and pipeline. This can increase the service life of the oil pump 4, the oil must be clean, the oil suction filter should be replaced in time, too much oil impurities to the plunger pump inside the plunger spoiled there is no warranty. Do these four points, can greatly improve the service life of the plunger pump!

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.
