【Specific embodiment】
Refer to Figure of description 1 to shown in accompanying drawing 18, the present invention is one kind full frequency band operating mode adaptive-filtering, magnetic
The oil filter changed, adsorb and be centrifuged, it is by base plate 6, wave filter 8, U-shaped separation of particles module 3, oil returning tube 7, inner core 15, spiral
A few part such as runner 17, filter core 18, outer barrel 19 and end cap 25 forms.Wherein, described wave filter 8, U-shaped separation of particles module 2,
Oil returning tube 7, outer barrel 19 are sequentially placed on base plate 6.
Described wave filter 8 is used for inputting hydraulic oil, and the pulsation pressure of the high, medium and low frequency range in hydraulic system that can decay
Power, and suppression flowed fluctuation.Described wave filter 8 is by input pipe 81, shell 88, efferent duct 89, elastic thin-wall 87, H mode filter
A few part composition such as 812 and cascaded H mode filter 813.
Wherein, described input pipe 81 is connected to one end of shell 89, and itself and a hydraulic oil inlet 1 are docked；Described efferent duct
811 other ends being connected to shell 89, it docks with U-shaped separation of particles module 3.Described elastic thin-wall 87 is along the radial direction peace of shell
It is loaded in shell 88.The axis of described input pipe 81 and efferent duct 89 not on the same axis, so can improve more than 10%
Filter effect.
Described input pipe 81, efferent duct 89 and elastic thin-wall 87 are collectively forming a c-type cavity volume wave filter, thus hydraulic pressure of decaying
System high-frequency pressure fluctuation.After processing by lumped-parameter method, the filter transmission coefficient that obtains is：
Velocity of sound L in a mediumVC-type cavity volume length SVC-type cavity volume volume Z characteristic impedance
γ transmission coefficient f pressure oscillation frequency SIInput pipe cross-sectional area.
From above formula, c-type wave filter is similar with the electric capacity effect in circuit.The pressure pulse wave of different frequency passes through should
During wave filter, transmission coefficient is different with frequency.Frequency is higher, then transmission coefficient is less, and this shows the pressure pulse wave of high frequency
Decay more severe in device after filtering, thus serving the effect eliminating high frequency pressure pulsations.
The design principle of described c-type cavity volume wave filter is as follows：When in pipeline, the fluctuating frequency of pressure is higher, the pressure of fluctuation is made
On fluid, pinch effect is produced to fluid.When the flow of change enters c-type cavity volume by input pipe, liquor stream exceedes averagely
Flow, the cavity volume of expansion can absorb unnecessary liquor stream, and releases liquor stream when less than average discharge, thus absorption pressure pulsating energy
Amount.
Described elastic thin-wall 87 weakens hydraulic system medium-high frequency pressure fluctuation by being forced to mechanical oscillation.By lumped parameter
After method is processed, the elastic thin-wall intrinsic frequency that obtains is：
K elastic thin-walled structures coefficient h elastic thin-wall thickness R elastic thin-wall radius
The mass density of the Young's modulus ρ elastic thin-wall of E elastic thin-wall
The Poisson's ratio of the current-carrying factor mu elastic thin-wall of η elastic thin-wall.
Substitute into actual parameter, simulation analysis are carried out to above formula it is found that the intrinsic frequency generally ratio H type of elastic thin-wall 87
The intrinsic frequency of wave filter is high, and its attenuation band is also wide than H mode filter.In relatively wide frequency band range, elasticity
Thin-walled has good attenuating to pressure fluctuation.Meanwhile, the elastic thin-wall radius in the filter construction of the present invention is larger
And relatively thin, its intrinsic frequency, closer to Mid Frequency, can achieve the effective attenuation to the medium-high frequency pressure fluctuation in hydraulic system.
The design principle of described elastic thin-wall 87 is as follows：When producing intermediate frequency pressure fluctuation in pipeline, c-type cavity volume is to pressure wave
Dynamic damping capacity is weaker, and the periodically pulsing pressure continuous action flowing into wave filter c-type cavity volume is on elastic thin-wall 87.Elasticity
Thin-walled then does periodic vibration by the frequency of fluctuation pressure, and this forced vibration consumes the pressure fluctuation energy of fluid, thus real
Existing Mid Frequency pressure filtering.From the principle of virtual work, elastic thin-wall consumes ability and its forced oscillation of fluid pulsation pressure energy
Potential energy when dynamic and kinetic energy sum are directly related, and in order to improve Mid Frequency filtering performance, the radial design of elastic thin-wall is long-range
In pipe radius, and the thickness of thin-walled is less, and representative value is less than 0.1mm.
Further, form resonance series cavity volume I84 between described elastic thin-wall 87 and shell 88 and parallel resonance is held
Chamber 85.The outside of described resonance series cavity volume I84 sets a resonance series cavity volume II83, described resonance series cavity volume I84 and series connection
Connected by the taper insertion tube 82 of some uniform arrangements between resonance cavity volume II83, the wider place of described taper insertion tube 82 opening
In resonance series cavity volume II83, its taper angle is 10 °.Some tapers are uniformly had on the axial direction of described elastic thin-wall 87 become
Structural damping hole 86, mutually staggers in the position of taper structure changes damping hole 86 and taper insertion tube 82.
Described H mode filter 812 is located in parallel resonance cavity volume 85, and it is connected with taper structure changes damping hole 86.Institute
State the wider place of taper structure changes damping hole 86 opening to be located in resonance series cavity volume I84 and parallel resonance cavity volume 85, its taper angle
For 10 °.After processing by lumped-parameter method, the wave filter natural angular frequency that obtains is：
Velocity of sound L in a medium1The long D of damping hole1Damping bore dia
L2Parallel resonance cavity volume height D2Parallel resonance cavity volume diameter.
Described cascaded H mode filter 813 is located in resonance series cavity volume I84 and resonance series cavity volume II83, and it also and is bored
Deformation structure damping hole 86 is connected.After processing by lumped-parameter method, two natural angular frequencies of cascaded H mode filter 813 are：
Velocity of sound l in a medium1The long d of damping hole1Damping bore dia l3Resonance pipe range
d3Resonance pipe diameter l2Resonance series cavity volume 1 height d2Resonance series cavity volume 1 diameter
l4Resonance series cavity volume 2 height d4Resonance series cavity volume 2 diameter.
Described H mode filter 812 and cascaded H mode filter 813 are axially symmetrical set, and form the filtering of connection in series-parallel H type
Device, for broadening frequency filtering scope and make overall structure more compact.The present invention circumferentially multiple connection in series-parallel H types of interface distributions
Wave filter (in figure only depicts 2), is separated with dividing plate 20, the resonance bands of this multiple wave filter are different each other,
Whole medium and low frequency filtering frequency range can be covered after combining comprehensively, realize the full range spectral filter of medium and low frequency section.
All can find, cascaded H mode filter has by H mode filter in Fig. 6 and cascaded H mode filter frequency characteristic and formula
2 natural angular frequencies, at crest, filter effect is preferable, and does not then substantially have filter effect at trough；H mode filter has 1
Individual natural angular frequency, equally at crest, filter effect is preferable, and does not then substantially have filter effect at trough；It is suitable to select
Filter parameter, makes the natural angular frequency of H mode filter just fall between 2 natural angular frequencies of cascaded H mode filter, such as
In certain frequency range, shown in Fig. 7, both defined the natural reonant frequency peak value of 3 next-door neighbours, in this frequency range, no
It is at crest by the fluctuating frequency of pressure or at trough, all can guarantee that preferable filter effect.Multiple connection in series-parallel H mode filters
The wave filter group constituting both can cover whole medium and low frequency section, realizes the full range spectral filter of medium and low frequency section.
Further, described taper structure changes damping hole 86 is made up of cone shaped elastic damping hole pipe 16 and slot apertures 15, taper
Narrow end is opened on elastic thin-wall 87.Wherein cone shaped elastic damping hole pipe 16 Young's modulus than elastic thin-wall 87 Young's modulus
Big, with change in fluid pressure stretching or can compress；The Young's modulus of slot apertures 15 is than the Young mould of cone shaped elastic damping hole pipe 16
Amount is big, can be turned on and off with Fluid pressure.Therefore when the fluctuating frequency of pressure falls in high band, c-type cavity volume filter construction
Strobe, cone shaped elastic damping hole pipe 16 and slot apertures 15 are all in Figure 10 (a) state；And work as ripple frequency and fall in Mid Frequency
When, filter construction is changed into c-type cavity volume filter construction and elastic thin-wall 87 filter structure concurs, and cone shaped elastic damps
Hole pipe 16 and slot apertures 15 are all in Figure 10 (a) state；When ripple frequency falls in some specific Frequencies, filter construction
It is changed into plug-in type connection in series-parallel H mode filter, c-type cavity volume filter construction and elastic thin-wall filter structure to concur, taper
Elastic damping hole pipe 16 and slot apertures 15 all in Figure 10 (b) state, due to the intrinsic frequency quilt of plug-in type connection in series-parallel H mode filter
It is designed as consistent with these particular low frequency ripple frequencies, big to fundamental frequency energy system and can play preferable filter effect；Work as arteries and veins
Dynamic frequency fall the low-frequency range beyond some CFs when, cone shaped elastic damping hole pipe 16 and slot apertures 15 are all in Figure 10 (c)
State.Such structure changes wave filter design both ensure that the full frequency band full working scope filtering of hydraulic system, reduces normal work again
Under condition, the pressure loss of wave filter is it is ensured that the hydraulic pressure rigidity of system.
The present invention can also the pulsation decay of solid line operating mode self-adaptive pressure.When hydraulic system working conditions change, both executive components
Suddenly stop or run, and when the opening of valve changes, the characteristic impedance of pipe-line system can be led to undergo mutation, so that former pipe
Road pressure also changes therewith with the curve of change in location in time, then the position of pressure peak also changes.Due to the present invention
The axial length of wave filter be designed as pulsing wavelength more than system main pressure, and the connection in series-parallel H mode filter group of wave filter
Cavity volume length, the length of c-type cavity volume wave filter and the length of elastic thin-wall and wave filter axial length equal it is ensured that pressure
Peak is constantly in the effective range of wave filter；And the taper structure changes damping hole of connection in series-parallel H mode filter is opened
On elastic thin-wall, it is uniformly distributed in the axial direction, resonance cavity volume 1 is equally distributed identical by multiple axial directions with resonance cavity volume 2
The taper resonantron of parameter is connected, conical damping hole and mutually stagger in taper resonantron position so that pressure peak change in location
The performance of wave filter is had little to no effect, it is achieved thereby that operating mode adaptive-filtering function.In view of three kinds of filter structure axles
Suitable to size and wave filter, this larger size also ensure that hydraulic filter possesses stronger pressure fluctuation decay energy
Power.
