Maintenance of four-column hydraulic press before use

Maintenance of four-column Hydraulic Press before use

  • 1. Check whether the four-column hydraulic oil sump, oil level, and oil level meet the specified standards.
  • 2. Check whether the button can be used correctly and whether there is a card.
  • 3. Check whether the grounding wire of the four-column hydraulic machine motor is properly connected, and whether it is loose or damaged.
  • 4. Check whether the safety precautions of the four-column hydraulic press are complete and reliable.

The reason for the large leakage inside and outside the four-column hydraulic press

  • 1. The output shaft end oil seal of the four-column hydraulic press is invalid
  • 2. Front cover and other O-ring sealing screws
  • 3. At this time, the joint of the four-column hydraulic press can be tightened, and the sealing condition at the joint can be improved.
  • 4. Due to the flatness of the disc or the wear and strain during use, the internal leakage is large.
  • 5. The axial assembly clearance of the four-column hydraulic press is too large to cause internal leakage
  • 6. The temperature of the four-column hydraulic oil is too high, the viscosity of the oil is too low, or the shaft is broken.
