Abstract
The utility model discloses a kind of filter cores of high contamination capacity structure, upper end cover skeleton, filtering layer and bottom end cover are cured as a single entity between each other by high-temp glue, filtering layer helicla flute is machined with, and fluid hole is along the circumferential direction uniformly drilled in helicla flute along upper end cover skeleton axis installation filtering layer.Upper end cover is structure as a whole with skeleton, the filter area of bigger is provided for filter core, using New type corrugated forming technique, it can make filter area bigger under equal installation space, under equal installation space and working environment, for the filter core of such structure compared with the filter core contamination capacity higher of ordinary construction, usage time is longer.
Description
Technical field
The utility model is related to a kind of filter cores of novel high contamination capacity structure, belong to hydraulic filtering field, as to tight
Gather the filtering of type hydraulic work system medium.
Background technology
Hydraulic system common filter element in home and abroad is glued filter core for glass fiber paper at present, and such filter core has processing week
The features such as phase is short, filter efficiency is high, service life is long.Paper filter element belongs to expendable Hydraulic Elements, not reproducible use.To ensure
The normal work of hydraulic system should be replaced in time after filter core to longevity.Therefore, the service life of filter core directly affects hydraulic system
Maintenance period.Influencing filter core service life factor is mainly：The dustiness and filter core itself of hydraulic work system medium are received
Dirty capacity.The dustiness of hydraulic work system medium is determined by the characteristic of hydraulic system itself.It needs a kind of high to receive dirt thus
The filter core of capacitive structure is to reduce the maintenance period of hydraulic system.
Invention content
The task of the utility model is to propose that a kind of filter core has the contamination capacity of bigger, prolongs the service life, reduces dimension
A kind of filter core of high contamination capacity structure of shield expense.
The task of the utility model be done in such a way that it is characterized in that：Upper end cover skeleton, filtering layer and bottom end cover mutually it
Between be cured as a single entity by high-temp glue, along upper end cover skeleton axis installation filtering layer at be machined with filtering layer helicla flute, and in spiral
Fluid hole is along the circumferential direction uniformly drilled in slot.The upper end cover is integrated with skeleton.Radius of corner is different at filtering layer dog-ear, interior
Circle small fillet radius, outer circle great circle angular radius are arranged alternately according to this, and inner ring makes it in identical installation space using small round corner
Can arrange more ripples, increase filter area.
The utility model has the following effects that：Upper end cover is structure as a whole with skeleton, and the filtering of bigger is provided for filter core
Area using New type corrugated forming technique, can make filter area bigger, in equal installation space and work under equal installation space
Make under environmental condition, compared with the filter core contamination capacity higher of ordinary construction, usage time is longer for the filter core of such structure.
Description of the drawings
Fig. 1 is the structure diagram of the utility model；Fig. 2 is the structure diagram of ripple forming.
Drawing explanation：1st, upper end cover skeleton, 2, filtering layer, 3, bottom end cover, 4, helicla flute, 5, fluid hole, 6, filtering layer.
Specific embodiment
The upper end skeleton that the technical program is related to replaces general separate structure to replace general split using integral structure
Structure, former round mode is replaced using small flow resistance skeleton round type, and former ripple forming is replaced using big filter area ripple forming
Technology, therefore under identical installation space, it can make filter core that there is the contamination capacity of bigger, and can ensure the premise of frame strength
The lower flow resistance for reducing skeleton.
Specific embodiment is as shown in Figure 1, upper end cover skeleton 1, filtering layer 6 and bottom end cover 3 pass through high temperature adhesive curing between each other
It being connected as a single entity, the upper end cover is integrated with skeleton, and filtering layer helicla flute 4 is machined with along upper end cover skeleton axis installation filtering layer,
And the purpose of fluid hole 5 is along the circumferential direction uniformly drilled in helicla flute, processes this fluid hole is before frame strength is ensured
Putting reduces the flow resistance of product, so as to increase filter core capacity.
The filtering layer is as shown in Fig. 2, filtering layer 2 is the technology using big filter area ripple forming, using special when clapping ripple
Make radius of corner difference at filtering layer dog-ear with mold, inner circle small fillet radius, outer circle great circle angular radius is arranged alternately according to this, interior
Circle makes its more ripple that can arrange in identical installation space using small round corner, increases filter area, by such
The contamination capacity of filter core can be increased by improving.
The technical program makes filter core have the contamination capacity of bigger under identical installation space, can under equal installation space
So that filter area bigger.
Claims (3)
