Description

Technical Field

[0001] The present invention relates to the technical field of hydraulic valve block cleaning, and particularly refers to a double-station working platform for pressure testing and cleaning of hydraulic valve blocks. Background Art

[0002] At present, due to deep hole machining problems of hydraulic valve blocks, a large amount of iron filings and impurities remain in the flow channels of the valve blocks. The remaining iron filings are the main reason for the failure of the actuating components and control components of the hydraulic system. Usually, high-pressure ultrasonic cleaning or cleaning methods such as soaking in kerosene or gasoline are used to clean the valve blocks to remove the iron filings. For complex valve blocks, because the flow channels are intertwined and the sizes of the flow channels are different, the internal flow channels cannot be cleaned thoroughly by the usual cleaning methods, and it will take a lot of manual time and be greatly affected by the quality of the operators.

[0003] For the penetration and leakage of the existing complex flow channels, usually after the valve block is assembled to the equipment, it can be detected whether there is a problem of unpenetrated flow channels through methods such as test running. Minor leakage and other problems are generally not detectable because they are assembled to the equipment and are greatly affected by other factors. Summary of the Invention

[0024] 5. Since the hydraulic oil will stick to a lot of iron filings when flushing the through holes of the hydraulic valve block, polluting the hydraulic oil, a filtration system is provided in this application to filter the hydraulic oil, which can better ensure the cleanliness of the hydraulic oil.
