【Specific embodiment】
Refer to shown in Figure of description 1 to accompanying drawing 19, this utility model is filtered using full frequency band operating mode self adaptation for a kind of
Ripple, separation and moulding Oil Monitoring device, which is arranged on fluid pressure line 9, and which is by wave filter 8, separation adsorption module 2, rotation
Turn a few part compositions such as moulding module 3, detection coil 4, reference coil 5, demagnetization module 6, flow transducer 7 and ECU1.
Wherein, the wave filter 8, separate adsorption module 2, rotate moulding module 3, detection coil 4, flow transducer 7, disappear
Magnetic module 6 is successively set on fluid pressure line 9.The ECU1 be electrically connected with and control wave filter 8, separate adsorption module 2,
Rotate moulding module 3, detection coil 4, reference coil 5, demagnetization module 6 and flow transducer 7.
As the flow velocity of fluid affects very big to detecting characteristic, with the increase of oil flow, the sensitivity of detection and
Output voltage will all occur significant change;Meanwhile, the flow of fluid also has large effect to detecting output, when flow increases
When, output voltage also can be with change, and this concordance and availability influence to testing result is very big, for this purpose, this utility model
8 stable hydraulic system pressure of wave filter and flow are increased before detection.
The wave filter 8 is by input pipe 81, shell 88, outlet tube 89, elastic thin-wall 87, H mode filters 812 and series connection
A few part compositions such as H mode filters 813.
Wherein, the input pipe 81 is connected to one end of shell 89, for being input into fluid;The outlet tube 811 is connected to
The other end of shell 89, which is docked with adsorption module 2 is separated.The elastic thin-wall 87 along shell radially installed in shell 88
It is interior.The axis of the input pipe 81 and outlet tube 89 can improve more than 10% filter effect not on the same axis, so.
The input pipe 81, outlet tube 89 and elastic thin-wall 87 are collectively forming a c-type cavity volume wave filter, so as to hydraulic pressure of decaying
System high-frequency pressure fluctuation.By the filter transmission coefficient that obtains after lumped-parameter method process it is:
Velocity of sound L in a-mediumV- c-type cavity volume length SV- c-type cavity volume volume Z-characteristic impedance
γ-transmission coefficient f-pressure oscillation frequency SI- input 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 is by being somebody's turn to do
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, so as to serve the effect for eliminating high frequency pressure pulsations.
The design principle of the 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
Pinch effect is produced used in convection cell on fluid.When the flow of change enters c-type cavity volume by input pipe, liquid stream exceedes average
Flow, the cavity volume of expansion can absorb many extraction raffinate streams, and liquid stream is released when less than average discharge, so as to absorption pressure pulsating energy
Amount.
The elastic thin-wall 87 weakens hydraulic system medium-high frequency pressure fluctuation by being forced to mechanical vibration.By lumped parameter
After method process, the elastic thin-wall natural frequency that obtains is:
K-elastic thin-walled structures coefficient h-elastic thin-wall thickness R-elastic thin-wall radius
The mass density of Young's moduluss ρ of E-elastic thin-wall-elastic thin-wall
The Poisson's ratio of the current-carrying factor mu-elastic thin-wall of η-elastic thin-wall.
Actual parameter is substituted into, simulation analysis are carried out to above formula it is found that the natural frequency of elastic thin-wall 87 is generally than H type
The natural 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 filter construction of the present utility model
Larger and relatively thin, its natural frequency is capable of achieving effectively declining to the medium-high frequency pressure fluctuation in hydraulic system closer to Mid Frequency
Subtract.
The design principle of the 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 of inflow 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 the forced vibration consumes the pressure fluctuation energy of fluid, so as to reality
Existing Mid Frequency pressure filtering.From the principle of virtual work, elastic thin-wall consumes the ability of fluid pulsation pressure energy and its forced oscillation
Potential energy and kinetic energy sum when dynamic is 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, resonance seriess cavity volume I84 is formed between the elastic thin-wall 87 and shell 88 and parallel resonance is held
Chamber 85.A resonance seriess cavity volume II83, the resonance seriess cavity volume I84 and series connection are set on the outside of the resonance seriess cavity volume I84
Connected by the taper insertion tube 82 of some uniform arrangements between resonance cavity volume II83, the taper insertion tube 82 is open wider place
In resonance seriess cavity volume II83, its taper angle is 10 °.Uniformly it is provided with some tapers to become in the axial direction of the elastic thin-wall 87
Mutually stagger the position of structural damping hole 86, taper structure changes damping hole 86 and taper insertion tube 82.
The H mode filters 812 are located in parallel resonance cavity volume 85, and which is connected with taper structure changes damping hole 86.Institute
State taper structure changes damping hole 86 and be open wider place in the resonance seriess cavity volume I84 and parallel resonance cavity volume 85, its taper angle
For 10 °.By the wave filter natural angular frequency that obtains after lumped-parameter method process it is:
A --- velocity of sound L in medium1--- the long D of damping hole1--- damping bore dia
L2--- parallel resonance cavity volume height D2--- parallel resonance cavity volume diameter.
In the resonance seriess cavity volume I84 and resonance seriess cavity volume II83, which is also and cone for the cascaded H mode filter 813
Deformation structure damping hole 86 is connected.After by lumped-parameter method process, two natural angular frequencies of cascaded H mode filter 813 are:
Velocity of sound l in a-medium1The long d of-damping hole1- damping bore dia l3- resonance pipe range
d3- resonance pipe diameter l21 height d of-resonance seriess cavity volume21 diameter of-resonance seriess cavity volume
l42 height d of-resonance seriess cavity volume42 diameter of-resonance seriess cavity volume.
The H mode filters 812 and cascaded H mode filter 813 are axially symmetrical set, and constitute the filtering of connection in series-parallel H types
Device, for broadening frequency filtering scope and makes overall structure more compact.Circumferentially the multiple strings of interface distributions are simultaneously for this utility model
Connection H mode filters (2 are only depicted in figure), is separated with dividing plate 20 each other, and the resonance bands of this multiple wave filter are each not
It is identical, whole middle low frequency filtering frequency range, the full range spectral filter of low-frequency range in realization can be covered after combining comprehensively.
Can find that cascaded H mode filter has 2 by Fig. 6 H mode filters and cascaded H mode filter frequency characteristic and formula
Individual natural angular frequency, at the crest filter effect preferably, and at the trough then substantially no filter effect;H mode filters have 1
Natural angular frequency, equally at the crest filter effect preferably, and at the trough then substantially no filter effect;Select suitable filter
Ripple device parameter, makes the natural angular frequency of H mode filters just fall between 2 natural angular frequencies of cascaded H mode filter, such as schemes
Shown in 7, both defined in certain frequency range 3 close to natural reonant frequency peak value, in the frequency range, no matter
The fluctuating frequency of pressure can guarantee that preferable filter effect at crest or at trough.Multiple connection in series-parallel H mode filter structures
Into wave filter group can both cover it is whole in low-frequency range, the full range spectral filter of low-frequency range in realization.
Further, the 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 Young's moduluss of the Young's moduluss of cone shaped elastic damping hole pipe 16 than elastic thin-wall 87
It is big, can stretch with change in fluid pressure or compress;Young mould of the Young's moduluss of slot apertures 15 than 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) states;And work as ripple frequency and fall in Mid Frequency
When, filter construction is changed into c-type cavity volume filter construction and 87 filter structure of elastic thin-wall is concured, cone shaped elastic damping
Hole pipe 16 and slot apertures 15 are all in Figure 10 (a) states;When ripple frequency falls in some specific Frequencies, filter construction
It is changed into plug-in type connection in series-parallel H mode filters, 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) states, due to the natural frequency quilt of plug-in type connection in series-parallel H mode filters
It is designed as consistent with these particular low frequency ripple frequencies, big to fundamental frequency energy system and can plays preferable filter effect;Work as arteries and veins
Dynamic frequency fall the low-frequency range beyond some characteristic frequency 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, reduce normal work again
The pressure loss of wave filter under condition, it is ensured that the hydraulic pressure rigidity of system.
This utility model can also the pulsation decay of solid line operating mode self-adaptive pressure.When hydraulic system working conditions change, both performed
Element stops suddenly or runs, and the opening of valve is when changing, and the characteristic impedance of pipe-line system can be caused to undergo mutation, so that
Former pipeline pressure also changes therewith with the curve of time and change in location, then the position of pressure peak also changes.Due to this
The axial length of the wave filter of utility model is designed as more than system main pressure pulsation wavelength, and the connection in series-parallel H types of wave filter
The cavity volume length of wave filter group, the length of c-type cavity volume wave filter and the length of elastic thin-wall and wave filter axial length are equal, protect
Demonstrate,prove pressure peak position to be constantly in the effective range of wave filter;And the taper structure changes of connection in series-parallel H mode filters
Damping hole is opened on elastic thin-wall, is uniformly distributed in the axial direction, and resonance cavity volume 1 and resonance cavity volume 2 are uniformly divided by multiple axial directions
The taper resonantron of the identical parameters of cloth is connected, and conical damping hole and taper resonantron position are mutually staggered so that pressure peak
Change in location is had little to no effect to the performance of wave filter, it is achieved thereby that operating mode adaptive-filtering function.Filter in view of three kinds
Quite, this larger size also ensure that hydraulic filter possesses stronger pressure fluctuation for wave structure axial dimension and wave filter
Damping capacity.
The method that hydraulic pulsation filtering is carried out using hydraulic filter of the present utility model is as follows:
1), hydraulic fluid enters c-type cavity volume wave filter by input pipe, and the cavity volume of expansion absorbs many extraction raffinate streams, completes height
The filtering of frequency pressure fluctuation;
2) the pressure fluctuation energy of fluid, by 87 forced vibration of elastic thin-wall, is consumed, the filter of intermediate frequency pressure fluctuation is completed
Ripple;
3), by connection in series-parallel H mode filter groups, and taper structure changes damping hole, taper insertion tube and fluid are produced altogether
Shake, consume pulsation energy, complete the filtering of low frequency pulsation;
4), the axial length of wave filter is designed as more than hydraulic system main pressure pulsation wavelength, and the filter of connection in series-parallel H types

In the effective range of wave filter, the filtering of pressure fluctuation when realizing that system condition changes;
5), by the switch of the flexible and slot apertures of the cone shaped elastic damping hole pipe of taper structure changes damping hole, complete pressure
Pulsation adaptive-filtering.
