Dump Truck Cylinder Air Bleeder Valve Innovation
Many hydraulic cylinder manufacturers have shifted to a bleederless design for dump truck cylinders. The primary advantage of this new design is to automatically purge any trapped air from the installation process. Traditional bleeder designed dump cylinders have an open plunger end which allowed the plunger to fill with oil. Any air captured in the cylinder would rise to the top of the plunger; therefore requiring the air to be bled from the cylinder before the cylinder can operate properly.
The new bleederless design removes the ability for air to get trapped in the cylinder during installation. This is accomplished by using a closed plunger end, reducing the amount of air that can get trapped in the cylinder. Any air that may be in the cylinder once the cylinder is filled mixes with the oil and purges through the oil tank once the cylinder is extended and then retracted.
How to Use the Bleederless Design Hydraulic Cylinder
- Mount the cylinder to the equipment.
- Connect the hydraulic cylinder to the system and purge the air by performing a full extension and retraction 2 to 3 times.
- If air is still present; which can be identified by the cylinder performing with erratic, bouncing action, repeat the full extension cycles another 2 to 3 times.
- If the condition still does not improve, visually inspect all hydraulic connections and check for tightness before repeating the extension cycles.
