Description

Technical Field

[0001] The utility model relates to the technical field of filter element replacement of a hydraulic system water cooling filter, in particular to a hydraulic system water cooler filter element puller. Background Art

[0002] At present, after the filter element of the hydraulic system water cooling filter is installed in the equipment, it needs to be disassembled again when it is replaced or cleaned. During disassembly, it is difficult to pull out because of the suction between the filter element and the equipment wrapping part.
