Bleeding the hydraulics
Why is ventilation important?
Bleeding hydraulic systems is advisable for a variety of reasons .
Air inclusions can cause a diesel effect, especially at high pressures or pressure fluctuations. This effect contributes to oil aging and increased temperatures. Which subsequently leads to seal wear.
An additional negative effect is that air diffuses through the sealing material in the direction of the low-pressure side. The pressure drops so steeply on the surface of the seal that the air bubbles expand suddenly and damage the seal. Depending on the extent of such “micro-explosions”, the surfaces of the sealing and running surfaces can also be damaged very quickly in such a way that they look like they are exposed to abrasive wear.
Compressed air inclusions can destroy the sealing and guiding surface when this air is passing over.
In addition, valves can tend to malfunction due to air inclusions, which can also cause major damage.
