[detailed description of the invention]

Referring to shown in Figure of description 1 to accompanying drawing 19, the present invention is one operating mode adaptive-filtering, magnetizes, rotates Magnetic field and centrifugal Rose Box, it is by base plate 6, wave filter 8, U-shaped separation of particles module 3, oil returning tube 7, inner core 15, helical flow path 17, several parts such as filter element 18, outer barrel 19 and end cap 25 composition.Wherein, described wave filter 8, U-shaped separation of particles module 2, oil return Cylinder 7, outer barrel 19 are sequentially placed on base plate 6.

Described wave filter 8 is for inputting hydraulic oil, and the pulsation pressure of the high, medium and low frequency range that can decay in hydraulic system Power, and suppression flowed fluctuation.Described wave filter 8 is by input pipe 81, shell 89, outlet tube 811, elastic thin-wall 87, plug-in type H type Several parts compositions such as wave filter 812 and plug-in type 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 outlet tube 811 other ends being connected to shell 89, itself and U-shaped separation of particles module 3 are docked.Described elastic thin-wall 87 is pacified along the radial direction of shell It is loaded in shell 89.The axis of described input pipe 81 and outlet tube 811 the most on the same axis, so can improve more than 10% Filter effect.

Described input pipe 81, outlet tube 811 and elastic thin-wall 87 are collectively forming a c-type cavity volume wave filter, thus liquid of decaying Pressure system high-frequency pressure fluctuation.The filter transmission coefficient obtained after processing by lumped-parameter method is:

$\mathrm{\γ}=\frac{1}{1+{(\frac{2\mathrm{\π}f}{Z}\·\frac{S_V{L}_V}{S_{I}a})}^2}$

Velocity of sound L in a medium_VC-type cavity volume length S_VC-type cavity volume volume Z characteristic impedance

γ transmission coefficient f pressure oscillation frequency S_IInput pipe cross-sectional area.

From above formula, when the pressure pulse wave of different frequency is by this wave filter, transmission coefficient is different with frequency.Frequently Rate is the highest, then transmission coefficient is the least, and this shows that the pressure pulse wave of high frequency is decayed the most severe when device after filtering, thus rises Arrive 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 Act on convection cell on fluid and produce pinch effect.When the flow of change enters c-type cavity volume by input pipe 81, liquid stream exceedes Average discharge, the cavity volume of expansion can absorb unnecessary liquid stream, and releases liquid stream when less than average discharge, thus absorption pressure arteries and veins Energy.

Described elastic thin-wall 87 weakens hydraulic system medium-high frequency pressure fluctuation by being forced to mechanical vibration.By lumped parameter The elastic thin-wall natural frequency that method obtains after processing is:

$f_m=\frac{k^{2}h}{2{\mathrm{\πR}}^2}\·\sqrt{\frac{E}{12\mathrm{\ρ}(1+\mathrm{\η})(1-{\mathrm{\μ}}^2)}}$

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, above formula is carried out simulation analysis it is found that the natural frequency generally ratio H type of elastic thin-wall 87 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, elastic Thin-walled has good attenuating to pressure fluctuation.Meanwhile, the elastic thin-wall radius in the filter construction of the present invention is bigger And relatively thin, its natural frequency, closer to Mid Frequency, can realize 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 more weak, flows into the periodically pulsing pressure continuous action of wave filter c-type cavity volume inside and outside elastic thin-wall 87 On wall, elastic thin-wall 87 does periodic vibration by the frequency of fluctuation pressure, and this forced vibration consumes the pressure fluctuation energy of fluid Amount, thus realize the filtering of Mid Frequency pressure.From the principle of virtual work, elastic thin-wall consume fluid pulsation pressure energy ability and Potential energy and kinetic energy sum during its forced vibration are directly related, and in order to improve Mid Frequency filtering performance, the radius of elastic thin-wall sets Being calculated as much larger than pipe radius, and the thickness of thin-walled is less, representative value is less than 0.1mm.

Further, resonance series cavity volume I84, resonance series cavity volume are formed between described elastic thin-wall 87 and shell 89 II83 and parallel resonance cavity volume 85, described cavity volume 83,84,85 is across whole wave filter, it is hereby achieved that bigger resonance Cavity volume volume, strengthens attenuating.By an elastic baffle between described resonance series cavity volume I84 and resonance series cavity volume II5 810 separate.Uniformly having some conical damping holes 86 in the axial direction of described elastic thin-wall 87, described conical damping hole 86 opening is relatively Wide place is positioned at resonance series cavity volume I84 and parallel resonance cavity volume 85, and its taper angle is 10 °.Described elastic baffle 810 axial On uniformly have some tapers insert pipe 82, described taper insert pipe 82 connect resonance series cavity volume I84 and resonance series cavity volume II83.Described taper is inserted the wider place of pipe 82 opening and is positioned at resonance series cavity volume II83, and its taper angle is 10 °, described taper Mutually stagger in the position inserting pipe 82 and conical damping hole 86.

Described plug-in type H mode filter 812 is positioned at parallel resonance cavity volume 85, and it is connected with conical damping hole 86.Press The wave filter natural angular frequency that lumped-parameter method obtains after processing is:

$\begin{array}{cc}{\mathrm{\ω}}_r=a\sqrt{\frac{S}{L(V-LS)}}& (rad/s)\end{array}---\left(1\right)$

Velocity of sound L damping hole long S damping hole cross-sectional area V parallel resonance cavity volume volume in a medium.

Described plug-in type cascaded H mode filter 813 is positioned at resonance series cavity volume I84 and resonance series cavity volume II83, its Also it is connected with conical damping hole 86.After processing by lumped-parameter method, two natural angular frequencies of wave filter are:

${\mathrm{\ω}}_1=\frac{\sqrt{\mathrm{\π}}a}{\sqrt{2}\sqrt{k_1+k_2+\sqrt{{\[k_1-k_2\]}^2+\frac{4{(V_4-\frac{1}{4}{{\mathrm{\πd}}_3}^2{l}_3)}^2{l}_1{l}_3}{d_1^2{d}_3^2}}}}---\left(2\right)$

${\mathrm{\ω}}_2=\frac{\sqrt{\mathrm{\π}}a}{\sqrt{2}\sqrt{k_1+k_2-\sqrt{{\[k_1-k_2\]}^2+\frac{4{(V_4-\frac{1}{4}{{\mathrm{\πd}}_3}^2{l}_3)}^2{l}_1{l}_3}{d_1^2{d}_3^2}}}}---\left(3\right)$

Wherein:

$k_1=\frac{l_1(V_2+V_4-\frac{1}{4}{{\mathrm{\πd}}_1}^2{l}_1-\frac{1}{4}{{\mathrm{\πd}}_3}^2{l}_3)}{{d_1}^2}$

$k_2=\frac{(V_4-\frac{1}{4}{{\mathrm{\πd}}_3}^2{l}_3)l_3}{{d_3}^2}$

Described plug-in type H mode filter 812 and plug-in type cascaded H mode filter 813 are axially symmetrical set, and form slotting Enter formula connection in series-parallel H mode filter, for broadening frequency filtering scope and make overall structure more compact.The present invention divides at circumferentially interface The multiple plug-in type connection in series-parallel H mode filters (only depicting 2 in figure) of cloth, separate with dividing plate 820 each other.

By Fig. 6 plug-in type H mode filter and plug-in type cascaded H mode filter frequency characteristic and formula (1) (2) (3) Finding, plug-in type cascaded H mode filter has 2 natural angular frequencies, and at crest, filter effect is preferable, then base at trough Originally there is no filter effect；Plug-in type H mode filter has 1 natural angular frequency, and at crest, filter effect is preferable equally, and at ripple The most substantially filter effect is not had at paddy；Select suitable filter parameter, just make the natural angular frequency of plug-in type H mode filter Fall between 2 natural angular frequencies of plug-in type cascaded H mode filter, as it is shown in fig. 7, both formed in certain frequency range The natural reonant frequency peak values of 3 next-door neighbours, in this frequency range, no matter the fluctuating frequency of pressure is at crest or trough Place all can guarantee that preferable filter effect.The bank of filters that multiple plug-in type connection in series-parallel H mode filters are constituted both can cover whole Medium and low frequency section, it is achieved the entire spectrum filtering of medium and low frequency section.

Further, the inner side of described elastic thin-wall 87 is provided with colloid damping layer 88.Described colloid damping layer 88 interior Layer and outer layer are respectively outer layer elastic thin-wall 871 and internal layer elastic thin-wall 872, outer layer elastic thin-wall 871 and internal layer elastic thin-wall Connected by some pillars 814 are fixing between 872.Fill in interlayer between outer layer elastic thin-wall 871 and internal layer elastic thin-wall 872 There is the pure water 816 adding antifreezing agent, in pure water 816, be suspended with Bio-sil 815.Described colloid damping layer 88 is near outlet tube One end of 811 is connected with shell 89；Described colloid damping layer 88 is additionally provided with a piston 817 near one end of outlet tube 811.

Due to outer layer elastic thin-wall 871 with internal layer elastic thin-wall 872 spacing is the least and is connected, in pressure by pillar 814 is fixing When power pulsation acts perpendicularly to thin-walled, inside and outside wall produces and is close to consistent deformation, and colloid damping layer thickness is kept approximately constant, right Pressure fluctuation does not has damping action；The flow pulsation in 817 sensation level directions of piston of colloid damping layer 88, flow pulsation increases Qiang Shi, piston 817 pressurized makes colloid damping layer shrink, and squeezing action makes the water in colloid damping layer 88 logical by nanoscale conveying Road enters micron order central void；When flow pulsation weakens, piston 817 is by back-pressure, and now colloid damping layer expands, and colloid damps Water in Ceng is discharged through passage from central void.In the process, due to mechanics effect, the passage of silica gel 815 microchannel sorption The roughness effect of surface molecular yardstick and chemistry heterogeneous body effect, piston is followed colloid damping layer and is shunk and do in expansion process The interfactial work on " gas-liquid-solid " border, thus flow systolic implementation is decayed, its substantially parallel R mode filter.Should Wave filter is relative to the advantage of general liquid condenser: it is decayed by the way of the interfactial work on " gas-liquid-solid " border Flow pulsation, can absorb a large amount of mechanical energy in the case of not producing heat, and energy expenditure does not relies on piston speed, declines Decreasing effect rate is obviously improved.

Described wave filter 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 when the opening of valve changes, the characteristic impedance of pipe-line system can be caused to undergo mutation, so that Former pipeline pressure curve with change in location in time changes the most therewith, then the position of pressure peak also changes.Due to this The axial length of the wave filter of invention is designed as more than system main pressure pulsation wavelength, and the plug-in type connection in series-parallel H of wave filter The cavity volume length of mode filter group, the length of c-type cavity volume wave filter and the length of elastic thin-wall 87 and wave filter axial length phase Deng, it is ensured that pressure peak position is constantly in the effective range of wave filter；And conical damping hole 86 is opened in Thin Elastic On wall 87, being uniformly distributed in the axial direction, the taper uniformly having multiple identical parameters in the axial direction of elastic baffle 810 is inserted Pipe 82, conical damping hole 86 and taper are inserted pipe 82 position and are mutually staggered so that the pressure peak change in location property to wave filter Can have little to no effect, it is achieved thereby that operating mode adaptive-filtering function.In view of three kinds of filter structure axial dimensions and filtering Device is suitable, and this bigger size also ensure that hydraulic filter possesses stronger pressure fluctuation damping capacity.

The method that above-mentioned wave filter carries out hydraulic pulsation filtering is as follows:

1), hydraulic fluid enters c-type cavity volume wave filter by input pipe, and the cavity volume of expansion absorbs unnecessary liquid stream, completes height The filtering of pressure fluctuation frequently；

2), by elastic thin-wall 87 forced vibration, consume the pressure fluctuation energy of fluid, complete intermediate frequency pressure fluctuation Filtering；

3), by plug-in type connection in series-parallel H mode filter group, insert pipe by conical damping hole, taper and fluid produces 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 plug-in type string is also Connection H mode filter length, c-type cavity volume filter length and elastic thin-wall 87 length are equal with filter length, make pressure peak Position is constantly in the effective range of wave filter, it is achieved the filtering of pressure fluctuation when system condition changes.
