High pressure Rexroth A4VG 28 56 71 90 125 250 A4VG28HD3DMT1 32L-NSC10F003D-S for excavator parts hydraulic pump 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!
