Description

Technical Field

[0001] The utility model relates to the technical field of filter equipment, in particular to a vertical pipeline filter. Background Art

[0002] In the hydraulic system, the granular impurities contained in the hydraulic oil will cause wear on the relative moving surfaces of the hydraulic components, stagnation of the slide valve, and blockage of the throttling orifice, thereby affecting the normal operation of the hydraulic system and shortening the life of the hydraulic system. Therefore, it is necessary to filter out the granular impurities in the hydraulic oil through a filter to prevent the impurities from entering the hydraulic transmission system and precision hydraulic components and affecting the normal operation of the system.
