[detailed description of the invention]

Refer to shown in Figure of description 1 to accompanying drawing 16, the present invention be a kind of use full frequency band filtering, The oil filtering system electrifying, separate, adsorb and being centrifuged, it is divided by base plate 6, wave filter 8, U-shaped microgranule From module 3, oil returning tube 7, inner core 15, helical flow path 17, filter element 18, outer barrel 19 and end cap Several parts compositions such as 25.Wherein, described wave filter 8, U-shaped separation of particles module 2, oil returning tube 7, Outer barrel 19 is sequentially placed on base plate 6.

Described wave filter 8 for hydraulic oil is inputted, and can decay in hydraulic system high, medium and low The fluctuation pressure of frequency range, and suppression flowed fluctuation.Described wave filter 8 by input pipe 81, shell 89, Several parts compositions such as outlet tube 811, corrugated tube 83, elastic thin-wall 87 and colloid damping layer 88.

Wherein, described input pipe 81 is connected to one end of shell 89, and itself and a hydraulic oil inlet 1 are right Connect；Described outlet tube 811 is connected to the other end of shell 89, and it extends in shell 89, itself and U-shaped separation of particles module 3 is docked.Described elastic thin-wall 87 is installed on shell 89 along the radial direction of shell In.The axis of described input pipe 81 and outlet tube 811 the most on the same axis, so can improve The filter effect of more than 10%.

Described input pipe 81, outlet tube 811 and elastic thin-wall 87 are collectively forming a K-type wave filter, Thus hydraulic system high frequency pressure pulsations of decaying.The filter transmission obtained after processing by lumped-parameter method Coefficient is:

$\mathrm{\γ}=\frac{|Z{|}^2}{|Z{|}^2+{\left(\frac{2\mathrm{\ρ}a}{{\mathrm{\πd}}_2^2}\right)}^2}$

Velocity of sound ρ fluid density d in a medium₂Plug-in type outlet tube diameter Z characteristic hinders Anti-.

From above formula, K-type wave filter is similar with the electric capacity effect in circuit.The pressure of different frequency When pulsating wave is by this wave filter, transmission coefficient is different with frequency.Frequency is the highest, then transmission coefficient The least, this shows that the pressure pulse wave of high frequency is decayed the most severe when device after filtering, thus plays Eliminate the effect of high frequency pressure pulsations.

The design principle of described K-type wave filter is as follows: when in pipeline, the fluctuating frequency of pressure is higher, pressure Wave action convection cell on fluid produces pinch effect.When the flow of change enters K by input pipe During mode filter cavity volume, liquid stream exceedes average discharge, and the cavity volume of expansion can absorb unnecessary liquid stream, and Liquid stream, the energy thus absorption pressure is pulsed is released when less than average discharge.

Described elastic thin-wall 87 weakens hydraulic system medium-high frequency pressure fluctuation by being forced to mechanical vibration. The elastic thin-wall natural frequency obtained after processing by lumped-parameter method 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 elastic thin-wall 87 intrinsic Frequency is generally high than the natural frequency of H mode filter, and its attenuation band is also wide than H mode filter. In relatively wide frequency band range, elastic thin-wall has good attenuating to pressure fluctuation.With Time, the elastic thin-wall radius in the filter construction of the present invention is bigger and relatively thin, and its natural frequency is more leaned on Nearly 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, double Pipe plug-in type cavity volume wave filter is more weak to the damping capacity of pressure oscillation, flows into Double-pipe plug-in type cavity volume Periodically pulsing pressure continuous action is on the inside and outside wall of elastic thin-wall, owing to there being pillar between inside and outside wall Fixing connection, inside and outside elastic thin-wall does periodic vibration by the frequency of fluctuation pressure simultaneously, this forced oscillation The dynamic pressure fluctuation energy consuming fluid, thus realize the filtering of Mid Frequency pressure.Can by the principle of virtual work Knowing, elastic thin-wall consumes ability and potential energy during its forced vibration and the kinetic energy of fluid pulsation pressure energy Sum is directly related, and in order to improve Mid Frequency filtering performance, the radial design of elastic thin-wall is for being much larger than Pipe radius, and the thickness of thin-walled is less, representative value is less than 0.1mm.

Further, the resonance cavity volume 85 of cylinder is formed between described elastic thin-wall 87 and shell 89. Some conical damping holes 86 are uniformly had, to ensure in whole filter in the axial direction of described elastic thin-wall 87 Plug-in type connection in series-parallel filtering all can be realized in the range of ripple device.Conical damping hole 86 connection resonance cavity volume 85.The described wider place of conical damping hole opening is positioned at resonance cavity volume, and its taper angle is 10 °, is used for Broadening frequency filtering scope, the wave filter natural angular frequency obtained after processing by lumped-parameter method 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 in a medium Cavity volume volume.

Described corrugated tube 83 is wound on outside resonance cavity volume 85 in the shape of a spiral, and resonance cavity volume 85 is by many Individual taper is inserted pipe 82 and is connected.Described taper is inserted the wider place of pipe 82 opening and is positioned at corrugated tube 83, Its taper angle be 10 ° for broadening frequency filtering scope.Pipe 82 and taper damping are inserted in described taper Mutually stagger in the position in hole 86.Described corrugated tube 83 is connected by some arms 810 between respectively enclosing, Arm 810 is provided with switch 84.It is different that described corrugated tube 83 and resonance cavity volume 85 form plug-in type spiral Structure cascaded H mode filter.

As shown in Figure 4, cascaded H mode filter has 2 natural angular frequencies, filter effect at crest Preferably, at trough, the most substantially do not has filter effect；Plug-in type spiral isomery cascaded H mode filter In have employed corrugated tube 83 structure of spiral isomery, corrugated tube itself has elasticity, works as hydraulic system Flow and pressure fluctuation through corrugated tube, fluid media (medium) causes the vibration of hydraulic pressure-spring system, offsets Wave energy, thus play filter action；Meanwhile, the some arms 810 between each circle corrugated tube 83 Connection or disconnection, cause interference and the superposition of ripple, thus the frequency changing cascaded H mode filter be special Property；Reasonable arrangement filter parameter and the connection quantity of arm and position, can make cascaded H type filter The trough of the frequency characteristic of device is raised, and makes wave filter have good filtering at whole medium and low frequency Duan Jun Can, it is achieved the entire spectrum filtering of medium and low frequency section.

The inner side of described elastic thin-wall 87 is provided with colloid damping layer 88.Described colloid damping layer 88 Internal layer and outer layer are respectively outer layer elastic thin-wall 81 and internal layer elastic thin-wall 82, outer layer elastic thin-wall 81 And connected by some pillars 814 are fixing between internal layer elastic thin-wall 82.Outer layer elastic thin-wall 81 and interior It is filled with the pure water 816 adding antifreezing agent, in pure water 816 in interlayer between layer elastic thin-wall 82 It is suspended with Bio-sil 815.Described colloid damping layer 88 is near one end of outlet tube 811 and shell 89 It is connected；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 81 with internal layer elastic thin-wall 82 spacing is the least and is fixed by pillar 814 Connecting, when pressure fluctuation acts perpendicularly to thin-walled, inside and outside wall produces and is close to consistent deformation, colloid Damping layer thickness is kept approximately constant, and pressure fluctuation is not had damping action；Colloid damping layer 88 The flow pulsation in 817 sensation level directions of piston, when flow pulsation strengthens, piston 817 pressurized makes Colloid damping layer shrinks, and squeezing action makes the water in colloid damping layer 88 by nanoscale transfer passage Enter micron order central void；When flow pulsation weakens, piston 817 is by back-pressure, and now colloid damps Layer expands, and the water in colloid damping layer is discharged through passage from central void.In the process, due to silicon The mechanics effect of glue 815 microchannel sorption, the roughness effect of channel surface molecular scale and chemistry are non-all Mass effect, piston follows the boundary that colloid damping layer shrinks and does " gas-liquid-solid " border in expansion process Face merit, thus flow systolic implementation is decayed, its substantially parallel R mode filter.This filter Ripple device is relative to the advantage of general liquid condenser: it is by the boundary on " gas-liquid-solid " border The mode of face merit decays 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, extinction efficiency is obviously improved.

The present invention can also the pulsation decay of solid line operating mode self-adaptive pressure.When hydraulic system working conditions change, Both executive component stopped suddenly or ran, and when the opening of valve changes, can cause the spy of pipe-line system Property impedance is undergone mutation, so that former pipeline pressure curve with change in location in time changes the most therewith Become, then the position of pressure peak also changes.Axial length design due to the wave filter of the present invention For more than system main pressure pulse wavelength, and wave filter plug-in type spiral isomery cascaded H type filtering The cavity volume length of device, the length of K-type wave filter and the length of elastic thin-wall and wave filter axial length phase Deng, it is ensured that pressure peak position is constantly in the effective range of wave filter；And plug-in type spiral shell The conical damping hole 86 of rotation isomery cascaded H mode filter is opened on elastic thin-wall 87, in the axial direction Being uniformly distributed, corrugated tube 83 and the taper resonated between cavity volume 85 that spiral isomery is wound around insert pipe at axle To being uniformly distributed so that the performance of wave filter is had little to no effect by pressure peak change in location, thus Achieve operating mode adaptive-filtering function.In view of three kinds of filter structure axial dimensions and wave filter phase When, this bigger size also ensure that hydraulic filter possesses stronger pressure fluctuation damping capacity.

The method that the pressure fluctuation restraining device using the present invention carries out hydraulic pulsation filtering is as follows:

1), hydraulic fluid enters K-type wave filter by input pipe, and the cavity volume of expansion absorbs unnecessary liquid stream, Complete the filtering of high frequency pressure pulsations；

2), by elastic thin-wall 87 forced vibration, the pressure fluctuation energy of fluid is consumed, in completing The filtering of pressure fluctuation frequently；

3), by plug-in type spiral isomery cascaded H mode filter, inserted by conical damping hole, taper Enter pipe and fluid produces resonance, 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 connection in series-parallel H mode filter length, filter length and the same wave filter of elastic thin-wall 87 length Length is equal, makes pressure peak position be constantly in the effective range of wave filter, it is achieved system work The filtering of pressure fluctuation when condition changes.
