The hydraulic system of this machine includes motors, oil pumps, control valve manifolds, oil tanks and other systems and various connecting pipelines. The pipelines of the hydraulic system are all connected by high-pressure flanges to avoid leakage of hydraulic oil. All oil pipes are pickled before welding, and then after welding slag, deburring and secondary pickling to ensure the cleanliness of the hydraulic pipeline.

  1. Simple structure, easy to operate and suitable for different working environments.
    Functional stability and wear resistance.All pressure scales in each series achieve low noise work.
  2. The cylinder of fast forging hydraulic press is mainly processed by rolling to a certain extent, and the surface residual pressure is left on the surface to a certain extent, which is helpful to close the small cracks on the surface. In this way, the corrosion expansion is hindered to a certain extent, so as to improve the corrosion resistance of the surface, delay the generation or expansion of fatigue cracks, and thus improve the fatigue strength of the cylinder.
  3. high control precision.low speed operation stability is good. At lower speeds, the servo motor still runs very smoothly, with almost no vibration,good torque frequency characteristics. The servo motor is a constant force output, no matter high speed or low speed, torque will not change much. the servo motor has a certain overload capacity, even beyond the rated torque, it can also work normally.
  4. can achieve high power control, small pressure loss, small heating No high speed reversing impact With high switching reliability Quick reaction time
