Description
Technical field
The present invention relates to the oil filter device in airborne hydraulic systems, particularly a kind of oil of pressure pulsation that can suppress is filtered.
Background technique
Airborne hydraulic systems is a key subsystem of aircraft, and changes mechanical energy is the pressure energy of fluid by oil hydraulic pump by this system, and is sent to each functional subsystem by working fluid, completes predetermined task.Airborne hydraulic systems is great on aircraft safety impact.According to interrelated data introduction, the aircraft accident of about 50% is had to be caused by the fault of hydraulic system, so the reliability how improving hydraulic system is problem demanding prompt solution.
Oil filter is the critical elements in hydraulic system, and it can remove the pollutant in hydraulic oil, keeps oil cleanliness, guarantees the reliability of system element work.By oil filter being arranged on the suitable position of hydraulic system, the impurity in hydraulic oil liquid can being filtered, the dustiness of the fluid in system is reduced, keep the clean of hydraulic oil liquid, thus guarantee system normally work.
Existing oil filter device divides by the strobe utility of its material for core, mainly contains the filter of surface-type oil, the filter of degree of depth type oil and the filter of absorbent-type oil.The whole filtration of surface-type oil filter is realized by a geometric surface, and material for core has demarcates aperture uniformly, can the filtering impurity larger than orifice size.Pollution impurity under filter is trapped within the one side of filter core element by fluid upstream.The material for core of degree of depth type oil filter is porous pervious material, and inside has tortuous roundabout passage.The impurity being greater than surface apertures is directly trapped within outer surface, and less pollution impurity enters filter material inside, bumps against on conduit wall, obtains filtering due to suction-operated.The material for core of absorbent-type oil filter can directly the relative substance absorption in fluid in its surface, such as magnetic oil filter.
Can see, existing oil filter is all that fluid directly contacts tube wall.Due to plane hydraulic system many employings Variable plunger pump, and the output of the flow of pulsed is the inherent characteristic of oil hydraulic pump.Flow pulsation is pressure pulsation via fluid circuit impedance transformation, pressure pulsation directly acts on the tube wall of solid pipeline with the form of pulsating stress, this just makes pulsating stress can not only directly cause breaking of tube wall, and can directly cause pipe-supporting structural damage, especially cause the fretting wear of support structure surface, cause support stiffness to decline, cause pipeline natural frequency to reduce, there is solid liquid interation, and finally cause pipe-line system to lose efficacy.
Summary of the invention
The object of the present invention is to provide a kind of oil filter, it can suppress pressure pulsation, reduces the pulsating stress acted on tube wall, avoids the destruction to piping support structure, improves the reliability of whole system.
For achieving the above object, the invention provides a kind of oil of pressure pulsation that suppresses to filter, comprise base, filter core installation sleeve, filter core and filter cylinder, described filter core installation sleeve and described filter cylinder are arranged on described base, described filter core is sleeved on described filter core installation sleeve, and described filter cylinder to be sleeved on described filter core and to compress described filter core, it is characterized in that, between described filter core and described filter cylinder, there is certain interval, in described gap, fill copper wire.
Preferably, in described gap, be also provided with copper wire supporting base, this supporting base is fixed on described base, and described copper wire is sleeved on described copper wire supporting base.
Preferably, described base bottom is dunnage, and described dunnage is provided with boss.More preferably, described dunnage is square, and described boss is ring.More preferably, the center of described dunnage offers the outlet of oil filter, offers the import of oil filter around described outlet.Especially, the outlet of described oil filter is opened in outside the gradient of described dunnage center.In addition, through hole is offered in the corner of described dunnage.
Preferably, between described filter core installation sleeve and described base, and be all screw-thread fit between described filter cylinder and described base.
Consider the tightness of whole oil filter, preferably, carry out encapsulation process at described filter core installation sleeve and the connection part place of described base and the connection part place of described filter core installation sleeve and described filter core respectively.More preferably, encapsulation process can be carried out to these connection parts by following manner, namely the connection part place of described filter core installation sleeve and described base is provided with the first seal ring, the connection part place of described filter core installation sleeve and filter core is provided with the second seal ring.
Preferably, also encapsulation process can be carried out at the connection part place of described filter cylinder and described base.More preferably, the connection part place on described filter cylinder and described base top is provided with the 3rd sealed picture, and the outer wall below described filter cylinder offers annular groove, and described combined seal ring is sleeved in described annular groove.
In use, oil filter of the present invention is arranged on delivery side of pump place, and the entrance that described fluid flows out via described filter core fitting seat from pump flows into described oil filter, and is flowing through copper wire and filter core, and leach mouth outflow from oil, this completes the filtering function to fluid.Owing to being filled with suitable copper wire between filter core and filter cylinder, this just changes the ripple frequency of pump discharge place fluid, and then reaches the object suppressing its pressure pulsation.
Therefore, pressure pulsation of the present invention suppresses oil filter, both can know the pollutant in fluid, keep oil cleanliness, and effectively can suppress pressure pulsation again, and then improve the reliability of whole hydraulic system.In addition, this oil filter structure simple, easy to process, be easy to realize.
