Problems solved by technology

But this known technology only adopts a simple filtration principle, and the used filter has low dirt-holding capacity, and frequent cleaning or replacement of the filter core will increase the difficulty of operation, and frequent repeated operations are more time-consuming and labor-intensive. The amount of slag cleaning is small, and the filtration efficiency is low

Abstract

The invention refers to a method and system for purifying the hydraulic pressure oil in hydraulic pressure machine. The method includes magnetism absorbing step which absorbs the metal particles in the hydraulic oil through magnetism structure onto the magnetism structure and a filter step blocking the impurities in the sift filter core, and finishes the first grade filter, and the second filter step with a sorption filter; the system includes: forward oil boxes connected in series, oil heater, magnetism filter, oil pump, sorption filter, backwards oil boxes and electric control system. Each device is connected through oil pipes and valves, all of which are set in a mobile machine box, moves the box, the purification to hydraulic pressure oil of different locations can be carried on conveniently.

Description

technical field [0001] The invention relates to a method and system for purifying engine oil, in particular to a method and system for purifying hydraulic oil in a hydraulic machine. Background technique [0002] Hydraulic presses are widely used in various fields of the manufacturing industry. The hydraulic oil operating in the hydraulic system will be polluted by mechanical impurities due to the natural wear and shutdown rust of hydraulic components and oil delivery systems, as well as the intrusion of external impurities. The contaminated hydraulic oil will increase the wear of the hydraulic components of the equipment, reduce the service life of the equipment, and become the main factor affecting the effective operation rate and reliability of the equipment. Therefore, hydraulic oil pollution must be controlled. In the prior art, the common method is to replace with new oil or to purify, but hydraulic oil occupies a relatively large proportion in the operating cost of t...
