Entlüftenbleeding

Entlüftenbleeding refers to the process of removing air or gas from a closed hydraulic or pneumatic system. This air can accumulate during the initial filling of the system, after maintenance, or due to leaks. The presence of air can lead to several operational problems, including spongy or inconsistent lever response in hydraulic brakes, reduced efficiency in pneumatic tools, and the potential for cavitation in pumps.

The procedure for entlüftenbleeding typically involves locating bleed screws or valves, which are often found at the highest points of the system or at the components requiring the most precise operation, such as brake calipers. Once a bleed point is identified, a container is attached to the outlet to capture the expelled fluid. The bleed screw is then slowly opened, allowing the pressurized fluid to push out the air. In hydraulic systems, this is often done by operating the system's actuator (e.g., pressing the brake pedal) while the bleed screw is open, and then closing it before the actuator is released. This prevents air from being drawn back into the system.

For pneumatic systems, the process is similar, but instead of fluid, compressed air is expelled. Specialized bleeding tools or simple manual methods can be employed depending on the system's complexity and pressure. Regular entlüftenbleeding is a crucial part of system maintenance to ensure optimal performance and longevity.
