Abstract
The utility model relates to a filter element central tube structure, which is characterized in that a spiral rib plate is wrapped at the outer part of a central round tube, the lower part of the central round tube is fixedly connected onto an oil filter base, and a filter element is arranged on the outer side of the central tube in a sleeving manner, and the filter element is tightly pressed by an oil filter cover. The designed spiral central tube can play roles of flow guidance and reinforcing rib; and the structure is applied to a detachable filter, so that not only can the effects of flow guidance and impurity sedimentation can be realized, but also the filtering efficiency can be improved.
Description
Technical field
The utility model relates to a kind of filter core center tube structure, particularly relates to a kind of removable filter central pipe structure, belongs to automobile technical field.
Background technology
Energy-saving and emission-reduction are directions of automotive field development, especially emission-reduction technology research and application, traditional rotary mounting engine oil filter is when maintenance, whole filter assembly need to be changed, so not only waste resource but also contaminated environment, present removable cleaner is widely used, but therefore its central tube function singleness needs a kind of complex function center tube structure.
Summary of the invention
The purpose of this utility model is to provide a kind of filter core center tube structure, it is by a kind of spiral central tube of design, has not only played water conservancy diversion but also has played the effect of reinforcement, is applied in removable cleaner, water conservancy diversion, precipitated impurities can be played, filter efficiency can be improved again.
The technical solution of the utility model is achieved in that a kind of filter core center tube structure, it is characterized in that: it is outside that spiral helicine gusset wraps in the center pipe, pipe bottom, center is fixedly connected on oil filter base, and filter core is enclosed within the pipe outside, center, by the machine oil filter cover, filter core is compressed.
Good effect of the present utility model is that machine oil after filter element filtering is along the helical duct in the central tube outside until the top enters main oil gallery again, helical duct had both supported filter core and has prevented from caving in, played again the effect that water conservancy diversion, precipitated impurities improve filter efficiency, it adopts plastic material, and quality is light, intensity is high.
Description of drawings
Fig. 1 is the filter core center tube structure schematic diagram of utility model.
Fig. 2 is the filter core center tube structure scheme of installation of utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described: as shown in Fig. 1-2, a kind of filter core center tube structure, it is characterized in that: spiral helicine gusset wraps in central tube 3 outsides, advance the main oil gallery mouth and be positioned at central tube 3 tops, central tube 3 bottoms are fixedly connected on oil filter base 4, filter core 2 is enclosed within the pipe outside, center, by machine oil filter cover 1, filter core 2 is compressed.
Machine oil after machine oil filter core filters enters into outside central tube, this moment, machine oil can not directly enter engine oil channel by central tube, but the top along the spiral rib plate in the central tube outside from central tube enters central tube, and then enter the engine main oil gallery, such type of flow more is conducive to the precipitation of magazine in machine oil, has strengthened the filter efficiency of oil filter.
