ABSTRACT:
This invention relates to the method and apparatus for eliminating cavitation in the hydraulic system. In the hydraulic fluid there is great difference between the seperating pressure of the air, water content and volatile substance from said fluid and the saturated vapor pressure of said fluid. With the heating method and vacuumizing technique, the air, water content and volatile substance in said hydraulic fluid which are sealed in a tank may be seperated and exhausted. With the changing of volume changeable device, the working fluid is pressurized up to the operating pressure. The apparatus designed according to this invention may be used either a movable pre-treatment device to replace the working fluid in the hydraulic system or an independent hydraulic pump station.
