How To Bleed A Hydraulic Cylinder Without Bleeder Valve?

Bleeding a hydraulic cylinder without a bleeder valve can be more challenging, but it is still possible. Here’s a step-by-step guide on how to bleed a hydraulic cylinder without a bleeder valve:

  1. Safety Precautions:
    • Prioritize safety by wearing appropriate personal protective equipment, gloves, and safety glasses.
    • Make sure the hydraulic system is depressurized. Turn off the power source and relieve residual pressure by operating the control valve several times.
  2. Cylinder Positioning:
    • Position the hydraulic cylinder to allow air bubbles to rise to the highest point. This may involve tilting or rotating the cylinder.
  3. Fill the Cylinder:
    • Fill the cylinder with hydraulic fluid through the hydraulic line ports or access points.
    • Slowly add the fluid to avoid introducing air bubbles. Allow the fluid to settle and remove any trapped air using the following steps.
  4. Manual Priming:
    • With a cylinder filled with fluid, manually prime or force the air out of the cylinder using the following methods:
    • Gently stroke the cylinder’s piston rod back and forth to create pressure and force any trapped air toward the hydraulic line ports.
    • You can also tap or lightly strike the cylinder’s body using a rubber mallet or a wooden block to help dislodge air bubbles.
  5. Fluid Replenishment:
    • As you stroke the piston rod or tap the cylinder, keep an eye on the fluid level.
    • If the fluid level drops, replenish it with additional hydraulic fluid to maintain proper priming.
  6. Repeat the Process:
    • Continue the manual priming process, stroking the piston rod and tapping the cylinder until no more air bubbles are visible and the cylinder is properly primed.
    • Take your time and be patient during this process, as removing all the air may require multiple repetitions.
  7. System Testing:
    • Once you believe the cylinder is adequately bled, reconnect the hydraulic lines and fittings.
    • Slowly pressurize the hydraulic system while monitoring for any signs of air bubbles or leaks.
    • Operate the cylinder through its full range of motion to ensure smooth operation and check for irregularities.
  8. Ongoing Maintenance:
    • Regularly inspect the hydraulic system for any air accumulation or performance issues.
    • If you notice recurring air in the system, it may be necessary to revisit the bleeding process or seek professional assistance to identify and resolve any underlying issues.
