How to Bleed Hydraulic Cylinder?

Understanding how to bleed a hydraulic cylinder is crucial for the optimal functionality and longevity of the device. The process involves purging the system of air pockets that may compromise the hydraulic functions. Let's delve deeper into the process and its importance.

Why Bleed Hydraulic Cylinders?

Bleeding a hydraulic cylinder is necessary to ensure its optimal performance. Trapped air within the system can cause spongy or inconsistent operation. Moreover, it can lead to system damage due to the compressibility of air, which is not ideal in a hydraulic system.

Signs That Bleeding is Required

  • Unresponsive or slow cylinder action
  • Erratic cylinder movement
  • Decreased system performance
  • Noisy pump operation

How to Bleed a Hydraulic Cylinder

Bleeding a hydraulic cylinder involves a series of steps, which if followed correctly, can ensure the effective removal of air from the system.

Steps to Bleed a Hydraulic Cylinder

  1. Ensure the cylinder is at its lowest position.
  2. Loosen the bleeder screws at the top of the cylinder.
  3. Operate the system slowly until a steady stream of hydraulic fluid, free of air bubbles, is seen.
  4. Tighten the bleeder screws.
  5. Repeat the process if necessary.
