Hydraulic Press Repair Service Breakdown

Typical Hydraulic Press Repair Faults:

  • Leaking hydraulic cylinders requiring the seals replacing
  • Low hydraulic pressure often caused by the low viscosity of old hydraulic oil
  • High Hydraulic oil temperature, this should not exceed 150 degrees Fahrenheit
  • Hydraulic filters in need of cleaning or changing, replace the air cooled heat exchanger filter
  • Slow pressure build up,i.e more than 2 seconds – check relief valve is working
  • Faulty Hydraulic pump motor, the motor nipple has not been used as recommended by the motor manufacturer
  • Oil leaks – Tighten or replace leaking hoses or fitting
  • Electrical faults such as sticking contactors, faulty solenoids
  • Check foot pedal cable, re wire foot pedal cable

Typical Hydraulic Press Service Requirements

Inspect the Hydraulic Press at the beginning of each work shift:

  • Check that all Infra red,mechanical,electrical,guarding systems are functioning correctly
  • Make a visual inspection of Hydraulic Press, address small issues with a hydraulic press before they become significant problems
  • It is important to understand the function, design and operation of your Hydraulic Press
  • The operators role in service, maintenance of a Hydraulic Press is a major part of keeping the equipment running efficiently.
  • It is important to immediately investigate strange noises, vibrations, or something that doesn’t look right.
    The quicker hydraulic press problems are detected and corrected, can often means a less expensive fix.
  • It’s the small preventive maintenance measures that keep a Hydraulic Press up and running.

A maintenance check list should include the following:

  • Clean Hydraulic oil is the key to a healthy hydraulic system.
    Dirt particles may enter a aspirated hydraulic tank.
    Keeping the oil clean and filling the reservoir to capacity are critical, re filter the oil every 6 months, using a 10/15 micron filter, Completely replace the oil around 2000/3000 hours of actual use
  • Clean the tank and replace the suction filters before replacing the hydraulic oil
  • Check the hydraulic ram’s, the press hydraulic piston rod should be moist, but not dripping oil
  • Bronze bushings should be greased as necessary.
  • Check for oil leaks on all hydraulic lines
  • Check for loose bolts around the tooling area.
  • Check the connection between the hydraulic cylinder ram & the tooling being used
  • Check the oil temperature

Check light curtains:  to do this break the beam whilst the hydraulic cylinder is traveling down, do not put your hands into the Hydraulic Press, use a  length of steel – the press should stop immediately

Check emergency stop button: operate and re set the mushroom button

If there are any failures with the light curtains
or emergency button
Do not operate the Hydraulic Press,
immediately inform management or refer to the owner’s manual.

Electrical Systems:

  • Emergency stop, check the dual circuit
    look for arcing and welding of contactors – check the safety relay
  • Check cables on foot pedal
  • Check all terminal strip connections, relays, terminal
    boxes on motors
  • Check all printed circuit boards, look for physical damage (cracked solder joints, burned parts, etc.)
  • Check all voltages coming from power supplies and transformers
  • Check all external cables and switches fittings for damage
  • Check control panel cooling fans are operational
  • Clean control cabinet to remove dust particles
