Abstract
The utility model discloses a kind of hydraulic oil folding type filter element, comprise the cylindrical filter cartridge body of hollow, the two ends of described filter element body are connected with upper and lower end socket, described filter element body is coated with filter core layer, described filter core layer is made up of fiberglass layer and the polytetrafluoroethylene floor that is coated on fiberglass layer two-sided, and described filter core layer is outside equipped with filter core enhancement Layer.The beneficial effects of the utility model are mainly reflected in: the polytetrafluoroethylene floor on fiberglass layer two sides improves the filtering accuracy of filter core greatly, make filtering accuracy to reach 0.1mm.By filter core enhancement Layer, the intensity filter of whole filter core is increased, ensure that the filter area of filter core.
Description
Technical field
The utility model relates to a kind of folding type filter element, is especially applicable to hydraulic oil filter core.
Background technology
Hydraulic oil filter core is used for filtering outside in various oil system and is mixed into or the inner solid impurity produced in system running, on main oil suction road of installing in systems in which, on pressure oil circuit, on return line, in bypass, in independent filtration system.Existing filter core adopts individual layer glass to be formed, and filtering accuracy is low, and the scope of application is less.
Utility model content
The purpose of this utility model solves the problems of the technologies described above, and proposes a kind of hydraulic oil folding type filter element.
The utility model is achieved through the following technical solutions.
Hydraulic oil folding type filter element, comprise the cylindrical filter cartridge body of hollow, the two ends of described filter element body are connected with upper and lower end socket, described filter element body is coated with filter core layer, described filter core layer is made up of fiberglass layer and the polytetrafluoroethylene floor that is coated on fiberglass layer two-sided, and described filter core layer is outside equipped with filter core enhancement Layer.
Preferably, described filter core enhancement Layer is stainless steel wire stratum reticulare.
Preferably, described filter core layer is folding corrugated around filter element body.
The beneficial effects of the utility model are mainly reflected in: the polytetrafluoroethylene floor on fiberglass layer two sides improves the filtering accuracy of filter core greatly, make filtering accuracy to reach 0.1mm.By filter core enhancement Layer, the intensity filter of whole filter core is increased, ensure that the filter area of filter core.
Accompanying drawing explanation
Fig. 1: theory structure schematic diagram of the present utility model.
The side view of Fig. 2: Fig. 1, does not now comprise end cap.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described:
The utility model discloses a kind of hydraulic oil folding type filter element, shown in combination Fig. 1, Fig. 2, consistent with prior art, includes the cylindrical filter cartridge body 1 of hollow, and the two ends of described filter element body 1 are connected with upper cover 11, low head 12.
Unlike, described filter element body 1 is coated with filter core layer 2, the filter area of hydraulic oil and filter core during in order to strengthen filtration, described filter core layer 2 around filter element body in folding corrugated.
Described filter core layer 2 is made up of fiberglass layer and the polytetrafluoroethylene floor that is coated on fiberglass layer two-sided.The interpolation of polytetrafluoroethylene floor makes filter element filtering precision of the present utility model improve, and precision reaches 0.1mm.In addition, because this filter core is used for hydraulic pressure oil filtration, therefore upper and lower end socket all needs to adopt high temperature resistant, corrosion-resistant material.
Due to the cause of filter core applicable situation, need its filter core to have certain intensity and ensure its service life in use to support filter course, described filter core layer is outside equipped with filter core enhancement Layer 4, and described filter core enhancement Layer 4 is stainless steel wire stratum reticulare.Certainly, other meshed strengthening layer can also be adopted.Due to the increase of Stainless Steel silk screen layer, filter core layer is used more firm, meanwhile, ensure that its filter area in use, extend the service life of filter core.
The utility model still has numerous embodiments, all employing equivalents or equivalent transformation and all technical schemes formed, and all drops within protection domain of the present utility model.
