[detailed description of the invention]
Referring to shown in Figure of description 1 to accompanying drawing 17, the present invention uses wave filter for one, electrifies, separates and adsorb
Oil-filtering apparatus, 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, filter element
18, several parts such as outer barrel 19 and end cap 25 composition.Wherein, described wave filter 8, U-shaped separation of particles module 2, oil returning tube 7, outer
Bucket 19 is 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 it extends into a length of l1 in shell 89, itself and one
Hydraulic oil inlet 1 is docked;Described outlet tube 811 is connected to the other end of shell 89, and it extends into a length of l2 in shell 89,
Itself and U-shaped separation of particles module 3 are docked.Described elastic thin-wall 87 is installed in shell 89 along the radial direction of shell.Described input pipe
81 and outlet tube 811 axis 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 two-tube slip-on filter, thus decay
Hydraulic system high frequency pressure pulsations.The filter transmission coefficient obtained after processing by lumped-parameter method is:
Velocity of sound ρ fluid density d in a medium1Input pipe diameter Z characteristic impedance
d2Outlet tube diameter D cavity volume diameter l1Input inserts length of tube l2Outfan inserts pipe range
Degree L cavity volume total length and input outfan insert the difference of length of tube sum.
From above formula, Double-pipe plug-in type cavity volume 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 is the least, and this shows high frequency
Pressure pulse wave decay the most severe when device after filtering, thus serve eliminate high frequency pressure pulsations effect.
The design principle of described Double-pipe plug-in type wave filter is as follows: when in pipeline, the fluctuating frequency of pressure is higher, pressure oscillation
Act on convection cell on fluid and produce pinch effect.When the flow of change enters Double-pipe plug-in type cavity volume by input pipe, liquid
Stream exceedes average discharge, and the cavity volume of expansion can absorb unnecessary liquid stream, and releases liquid stream when less than average discharge, thus absorbs
Pressure fluctuation 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:
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, Double-pipe plug-in type cavity volume
Wave filter is more weak to the damping capacity of pressure oscillation, flows into the periodically pulsing pressure continuous action of Double-pipe plug-in type cavity volume at bullet
Property thin-walled inside and outside wall on, owing to having between inside and outside wall, pillar is fixing to be connected, and inside and outside elastic thin-wall is simultaneously by the frequency of fluctuation pressure
Rate does periodic vibration, and this forced vibration consumes the pressure fluctuation energy of fluid, thus realizes the filtering of Mid Frequency pressure.By
The principle of virtual work understands, and elastic thin-wall consumes ability and potential energy during its forced vibration and the kinetic energy sum of fluid pulsation pressure energy
Directly related, in order to improve Mid Frequency filtering performance, the radial design of elastic thin-wall is much larger than pipe radius, and the thickness of thin-walled
Spending 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 is near defeated
Entering pipe 81 side and be provided with taper insertion pipe 82, described taper is inserted pipe 82 and is connected 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 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:
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:
Wherein:
Velocity of sound l in a medium1The long d of damping hole1Damping hole diameter l3Insert pipe range
d3Insert pipe diameter V2Resonance series cavity volume 1 volume V4Resonance series cavity volume 2 volume.
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.This is created circumferentially interface and divides
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, the most basic at trough
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 trough
Place does not has filter effect the most substantially;Select suitable filter parameter, make the natural angular frequency of plug-in type H mode filter just fall
Between 2 natural angular frequencies of plug-in type cascaded H mode filter, as it is shown in fig. 7, both define in certain frequency range
The natural reonant frequency peak value of 3 next-door neighbours, in this frequency range, no matter the fluctuating frequency of pressure is at crest or at trough
All can guarantee that preferable filter effect.Multiple plug-in type connection in series-parallel H mode filters constitute bank of filters both can cover whole in
Low-frequency range, 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.Internal layer and the outer layer of described colloid damping layer 88 divide
Not Wei outer layer elastic thin-wall 81 and internal layer elastic thin-wall 82, if by the Heavenly Stems and Earthly Branches between outer layer elastic thin-wall 81 and internal layer elastic thin-wall 82
Post 814 is fixing to be connected.It is filled with in interlayer between outer layer elastic thin-wall 81 and internal layer elastic thin-wall 82 and adds the pure of antifreezing agent
Water 816, is suspended with Bio-sil 815 in pure water 816.Described colloid damping layer 88 is near one end of outlet tube 811 and shell
89 are 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 connected, at pressure by pillar 814 is fixing
When 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, to pressure
Power pulsation does not has damping action;The flow pulsation in 817 sensation level directions of piston of colloid damping layer 88, flow pulsation strengthens
Time, piston 817 pressurized makes colloid damping layer shrink, 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 damping layer expands, colloid damping layer
In water from central void through passage discharge.In the process, due to mechanics effect, the channel table of silica gel 815 microchannel sorption
The roughness effect of face molecular scale and chemistry heterogeneous body effect, piston follow colloid damping layer shrink and expansion process is done " gas-
Liquid-solid " interfactial work on border, thus flow systolic implementation is decayed, its substantially parallel R mode filter.This filtering
Device is relative to the advantage of general liquid condenser: it is decayed flow by the way of the interfactial work on " gas-liquid-solid " border
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, decay effect
Rate 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 components
Suddenly stop or running, and when the opening of valve changes, the characteristic impedance of pipe-line system can be caused to undergo mutation, so that former pipe
Pressure curve with change in location in time in road changes the most therewith, then the position of pressure peak also changes.Due to the present invention
The axial length of wave filter be designed as pulsing wavelength, and the plug-in type connection in series-parallel H type filter of wave filter more than system main pressure
The cavity volume length of ripple device group, the length of Double-pipe plug-in type cavity volume 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 connection in series-parallel H mode filter
Conical damping hole is opened on elastic thin-wall, is uniformly distributed in the axial direction 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 the pressure fluctuation restraining device using the present invention carries out hydraulic pulsation filtering is as follows:
1), hydraulic fluid enters Double-pipe plug-in type wave filter by input pipe, and the cavity volume of expansion absorbs unnecessary liquid stream, completes
The filtering of high frequency pressure pulsations;
2), by elastic thin-wall 87 forced vibration, consume the pressure fluctuation energy of fluid, complete the filter of intermediate frequency pressure fluctuation
Ripple;
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, Double-pipe plug-in type filter length and elastic thin-wall 87 length are equal with filter length, make pressure spike
Value position is constantly in the effective range of wave filter, it is achieved the filtering of pressure fluctuation when system condition changes.
