To prevent air and water intrusion hydraulic system
The hydraulic system to prevent air intrusions
At room temperature at atmospheric pressure and hydraulic oil contains volume ratio of 6 to 8% of the air, when the pressure is lowered, the air will be freed from the oil bubble burst so that hydraulic components "cavitation", producing the noise.
A lot of air into the oil will turn the "cavitation" phenomenon intensified hydraulic fluid compressibility increases, job insecurity, reduced work efficiency, the implementation of components, there work, "crawl" and other adverse consequences. In addition, the air will allow hydraulic oil oxidation, accelerate the deterioration of oil. To prevent air intrusion should note the following points:
After the maintenance and oil change according to random "manual" for excluding the air system to normal operation.
