[detailed description of the invention]

Referring to shown in Figure of description 1 to accompanying drawing 16, this utility model is that one full frequency band structure changes operating mode is adaptive Should filter and moulding Oil Monitoring equipment, it is arranged on fluid pressure line 9, and it is by wave filter 8, separation adsorption module 2, rotation Turn several parts composition such as moulding module 3, detection coil 4, reference coil 5, demagnetization module 6, flow transducer 7 and ECU1.

Wherein, described 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.Described 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.

Owing to the flow velocity of fluid is very big on detection characteristic impact, along with the increase of oil flow, the sensitivity of detection and Output voltage all will occur significant change；Meanwhile, the flow of fluid also has large effect to detection output, when flow increases Time, output voltage is as well as change, and this is very big to concordance and the availability influence of testing result, to this end, this utility model Add wave filter 8 stable hydraulic system pressure and flow before detection.

Described wave filter 8 is by several portions such as input pipe 81, shell 88, outlet tube 89, corrugated tube 83 and S type elastic thin-walls 87 It is grouped into.

Wherein, described input pipe 81 is connected to one end of shell 89, is used for inputting fluid；Described outlet tube 811 is connected to The other end of shell 89, itself and separation adsorption module 2 dock.Described S type elastic thin-wall 87 is installed on shell along the radial direction of shell In 88, in it, form expansion chamber 71 and contraction chamber 72.The axis of described input pipe 81 and outlet tube 89 the most on the same axis, this Sample can improve the filter effect of more than 10%.

Described input pipe 81, outlet tube 89 and S type elastic thin-wall 87 are collectively forming a S type cavity volume wave filter, thus decay Hydraulic system high frequency pressure pulsations.The filter transmission coefficient obtained after processing by lumped-parameter method is:

$\mathrm{\γ}=\frac{1}{1+{(\frac{2\mathrm{\π}f}{Z}\·\frac{\frac{2}{3}{k}_1{D}^3+k_2{d}^{2}L}{{d_I}^2\·a})}^2}$

Velocity of sound L contraction chamber length D expansion chamber diameter Z characteristic impedance in a medium

γ transmission coefficient f pressure oscillation frequency d_IInput pipe diameter d contraction chamber diameter

k₁Expansion chamber coefficient k₂Contraction chamber coefficient

From above formula, S type cavity volume wave filter is similar with the electric capacity effect in circuit.The pressure pulse wave of different frequency leads to When crossing this wave filter, transmission coefficient is different with frequency.Frequency is the highest, then transmission coefficient is the least, and this shows the pressure arteries and veins of high frequency Dynamic ripple is decayed the most severe when device after filtering, thus serves the effect eliminating high frequency pressure pulsations.Meanwhile, this practicality is new In the S type holding cavity structure of type, transitions smooth between expansion chamber and contraction chamber, contribute to reducing the system that cavity diameter sudden change brings The pressure loss.

The design principle of described S type cavity volume wave filter is as follows: when the flow of change enters the swollen of S type cavity volume by input pipe During swollen chamber, liquid stream exceedes average discharge, and the expansion chamber of expansion can absorb unnecessary liquid stream, and releases liquid when less than average discharge Stream, thus absorption pressure pulsation energy.The combination of multiple expansion chamber and contraction chamber then improves the fluctuation pressure of wave filter and absorbs Ability, namely filtering performance.Use curved surface to smoothly transit between expansion chamber and contraction chamber, then avoid by fluid boundary sudden change band That comes loses along stroke pressure and heating.

Described S type elastic thin-wall 87 weakens hydraulic system medium-high frequency pressure fluctuation by being forced to mechanical vibration.By lump The S type elastic thin-wall natural frequency that parametric 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 S type elastic thin-walled structures coefficient h S type elastic thin-wall thickness R S type elastic thin-wall radius

The mass density of the Young's modulus ρ S type elastic thin-wall of E S type elastic thin-wall

The Poisson's ratio of the current-carrying factor mu S type elastic thin-wall of η S type elastic thin-wall.

Substitute into actual parameter, above formula is carried out simulation analysis it is found that S type elastic thin-wall 87 natural frequency generally than The natural frequency of H mode filter is high, and its attenuation band is also wide than H mode filter.In relatively wide frequency band range, S Type elastic thin-wall has good attenuating to pressure fluctuation.Meanwhile, the S type in filter construction of the present utility model is elastic Thin-walled radius is bigger and relatively thin, and its natural frequency, closer to Mid Frequency, can realize the medium-high frequency pressure fluctuation in hydraulic system Effective attenuation.

The design principle of described S type elastic thin-wall 87 is as follows: when producing intermediate frequency pressure fluctuation in pipeline, and Double-pipe plug-in type holds Cavity filter is more weak to the damping capacity of pressure oscillation, and the periodically pulsing pressure continuous action flowing into Double-pipe plug-in type cavity volume exists On the inside and outside wall of S type elastic thin-wall, owing to having between inside and outside wall, pillar is fixing to be connected, and inside and outside S type elastic thin-wall is simultaneously by pulsation The frequency of pressure does periodic vibration, and this forced vibration consumes the pressure fluctuation energy of fluid, thus realizes Mid Frequency pressure Filtering.From the principle of virtual work, S type elastic thin-wall consumes potential energy during ability and its forced vibration of fluid pulsation pressure energy Directly related with kinetic energy sum, in order to improve Mid Frequency filtering performance, the radial design of S type elastic thin-wall is much larger than pipeline half Footpath, 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 S type elastic thin-wall 87 and shell 88.Described S type Some taper structure changes damping holes 86 are uniformly had in the axial direction of elastic thin-wall 87, equal to ensure in the range of whole wave filter Plug-in type connection in series-parallel filtering can be realized.Taper structure changes damping hole 86 connection resonance cavity volume 85.Described taper structure changes damping hole The wider place of opening is positioned at resonance cavity volume, and its taper angle is 10 °, for broadening frequency filtering scope, processes by lumped-parameter method After the wave filter natural angular frequency that obtains be:

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

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

Described corrugated tube 83 is wound on outside resonance cavity volume 85 in the shape of a spiral, and resonance cavity volume 85 inserts pipe 82 by multiple tapers Connection.Described taper insert the wider place of pipe 82 opening be positioned at corrugated tube 83, its taper angle be 10 ° for broadening frequency filtering model Enclose.Described corrugated tube 83 is connected by some arms 810 between respectively enclosing, and arm 810 is provided with switch 84.Described corrugated tube 83 He Resonance cavity volume 85 forms plug-in type spiral isomery cascaded H mode filter.

From the figure 3, it may be seen that cascaded H mode filter has 2 natural angular frequencies, at crest, filter effect is preferable, and at trough Place does not has filter effect the most substantially；The corrugated tube 83 that have employed spiral isomery in plug-in type spiral isomery cascaded H mode filter is tied Structure, corrugated tube itself has elasticity, when flow and the pressure fluctuation of hydraulic system cause liquid through corrugated tube, fluid media (medium) Pressure-spring system vibrates, and offsets Wave energy, thus plays filter action；Meanwhile, the some arms between each circle corrugated tube 83 The connection of 810 or disconnection, cause interference and the superposition of ripple, thus change the frequency characteristic of cascaded H mode filter；Reasonable arrangement is filtered Ripple device parameter and the connection quantity of arm and position, can make the trough of the frequency characteristic of cascaded H mode filter raise, make filtering Device has good filtering performance at whole medium and low frequency Duan Jun, it is achieved the entire spectrum filtering 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 7.Wherein the Young's modulus of cone shaped elastic damping hole pipe 16 is wanted than the Young's modulus of elastic thin-wall 7 Greatly, can be with change in fluid pressure stretching or compression；The Young's modulus of slot apertures 15 is than the Young's modulus of cone shaped elastic damping hole pipe 16 Want big, can be with fluid opened by pressure or closedown.Therefore when the fluctuating frequency of pressure falls at high band, S type cavity volume filter construction rises Filter action, cone shaped elastic damping hole pipe 16 and slot apertures 15 are all in Fig. 7 (a) state；And when ripple frequency falls at Mid Frequency, Filter construction becomes S type cavity volume filter construction and elastic thin-wall 7 filter structure concurs, cone shaped elastic damping hole pipe 16 and slot apertures 15 all in Fig. 7 (a) state；When ripple frequency falls at some specific Frequency, filter construction becomes Plug-in type connection in series-parallel H mode filter, S type cavity volume filter construction and elastic thin-wall filter structure concur, cone shaped elastic Damping hole pipe 16 and slot apertures 15 are all in Fig. 7 (b) state, owing to the natural frequency of plug-in type connection in series-parallel H mode filter is designed For consistent with these particular low frequency ripple frequencies, the system that fundamental frequency energy is big can be played preferable filter effect；When pulsation frequency Rate fall the low-frequency range beyond some characteristic frequency time, cone shaped elastic damping hole pipe 16 and slot apertures 15 are all in Fig. 7 (c) state. The design of such structure changes wave filter both ensure that the full frequency band full working scope filtering of hydraulic system, reduces again and filters under nominal situation The pressure loss of ripple device, it is ensured that the hydraulic pressure rigidity of system.

This wave filter 8 can also the pulsation decay of solid line operating mode self-adaptive pressure.When hydraulic system working conditions change, both performed unit Part 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 reality It is designed as more than system main pressure pulsation wavelength with the axial length of novel wave filter, and the plug-in type spiral of wave filter is different The cavity volume length of structure cascaded H mode filter, the length of S type cavity volume wave filter and the length of elastic thin-wall and wave filter axial length Equal, it is ensured that pressure peak position is constantly in the effective range of wave filter；Plug-in type spiral isomery cascaded H type is filtered The taper structure changes damping hole of ripple device is opened on S type elastic thin-wall, is uniformly distributed in the axial direction, the ripple that spiral isomery is wound around Taper between pipe and resonance cavity volume is inserted pipe and is axially being uniformly distributed so that pressure peak change in location is several to the performance of wave filter Not impact, it is achieved thereby that 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.

This wave filter 8 is used to carry out the method for hydraulic pulsation filtering as follows:

1), hydraulic fluid enters S 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 S type elastic thin-wall 87 forced vibration, consume the pressure fluctuation energy of fluid, complete intermediate frequency pressure fluctuation Filtering；

3), by plug-in type spiral isomery cascaded H mode filter, pipe and fluid are inserted in taper structure changes damping hole, taper Produce 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 string is also Connection H mode filter length, Double-pipe plug-in type filter length and S type elastic thin-wall 87 length are equal with filter length, make pressure Power peak is constantly in the effective range of wave filter, it is achieved the filtering of pressure fluctuation when system condition changes；

5), by the flexible of the cone shaped elastic damping hole pipe of taper structure changes damping hole and the switch of slot apertures, pressure is completed Pulsation adaptive-filtering.

Galling abrasive particle in machine oil can be divided into ferromagnetics microgranule (such as ferrum) and non-ferric according to its electromagnetic property Magnetic substance microgranule (such as copper, aluminum).Ferromagnetics microgranule strengthens the equivalent inductance of cell winding, and non-ferromagnetic material microgranule then weakens sensing The equivalent inductance of device coil.When two kinds of microgranules are simultaneously by detection coil, this monitoring device will lose efficacy.To this end, this practicality is new Type separates adsorption module 2 and separates both microgranules.Described separation adsorption module 2 is by the mechanical centrifugal module being sequentially connected with 21, magnetized module 22, magnetic suck module 23, electrification module 24 and electric adsorption module 25 form.

The moulding module of described rotation 3 is for improving the sensitivity of detection.Research shows: the inductance rate of change of cell winding It is directly proportional to the cube of abrasive particle radius.Meanwhile, the form of magnetizing mediums more trends towards elongate, and its demagnetizing factor is the least, magnetization Intensity is the biggest, and magnetizing field field intensity is the biggest.Change on sensor equivalent inductance affects the biggest.The moulding module of this rotation 3 is by aluminum matter A few part groups such as pipeline 31, some windings 32, iron shell 33, flange 34 and the moulding current output module of some rotations 35 Become.Wherein, described some windings 32 are rotating around outside aluminum matter pipeline 31；Described iron shell 33 is coated on aluminum matter pipeline 31； Described flange 34 is welded on the two ends of aluminum matter pipeline 31；The moulding current output module of each rotation 35 is connected to a winding 32.

The design principle of the moulding module of described rotation 3 is as follows: polymeric macroparticle enters with fluid after rotating moulding module 3, ECU1 controls to rotate moulding current output module 35, makes to flow through three-phase symmetrical electric current in the moulding current output module of rotation 35, should Electric current produces rotating excitation field in aluminum matter pipeline 31.Magnetized particles is acted on by magnetic field force under rotating excitation field effect, and Spirally advancing under the effect of this power, magnetic microparticles defines a lot of acicular texture along magnetic line of force direction, these acicular textures Magnetic field will be followed spin motion when magnetic field rotating, and specifically move along a straight line axially following fluid, radially then follow rotation Turn magnetic field to spin motion.Adjust three-phase symmetrical electric current and can change speed and the track of screw.Needle-like knot when motion When metal particle on structure and movement locus meets with, it is combined with one another to bulky grain polymer.By rotating moulding module 3, make oil The particle diameter of the metal particle in liquid increases form simultaneously and becomes elongated acicular texture so that the fiber number of metal particle increases the most greatly Add, further enhancing the sensitivity of Double-coil type detection.

Metallic wear particles is non-uniform Distribution in oil circuit, and variations in flow patterns is sufficiently complex, when particle size and material become During change, its changes of magnetic field caused is the faintest, if detection Magnetic field inhomogeneity will cause serious measurement error, makes detection spirit Sensitivity reduces；Double-coil type detection of particulates requires that the characteristic of detection line coil and a reference coil is completely the same simultaneously, and this is usually very Inaccessible, need the detection coil 7 of design to have the function of on-line automatic regulation for this.Specifically, described detection coil 7 Winding be made up of positive winding 71 and inverse winding 72, each winding is connected to an exciting current output module 73, and this exciting current is defeated Go out module 73 to be controlled by ECU module, its use digital potentiometer be AD5206, there is the output of 6 passages, can with ECU1 it Between realize single bus data transmission.ECU realizes the electricity to the polylith exciting current output module 73 magnetizing winding by monobus Stream sets and output.Amplifier AD8601 and metal-oxide-semiconductor 2N7002 achieve high-precision voltage follow by negative feedback and export.Constant High-current output have employed amplifier OPA 549 of the high voltage of Texas Instrument (TI), big electric current.

The operation principle of described detection coil 7 is as follows: in order to produce the magnetic field in same polarity direction and make up breach and make simultaneously The magnetic field become is unbalanced, and positive winding 71 is identical with the current characteristics in inverse winding 72, arranges on the axis direction of conduit under fluid pressure 9 There is multipair forward and reverse winding, control electric current by different exciting current output modules 73, it is possible to form the uniform magnetic of system requirements ?.

Further, described detection coil 4, reference coil 5 are in series, and both form a sensor.When detection coil 4 In middle time without abrasive particle, owing to detection coil 4 is identical with reference coil 5 characteristic, there is no output voltage.And when abrasive particle enters detection coil When 4, then causing the change of sensor output voltage, this variable quantity is metastable.When in fluid by there being big of metal During grain, cause disturbance of magnetic field, cause sensor coil to produce induction electromotive force.Utilize ferromagnetics and non-ferromagnetic material metal particle to former The otherwise impact in magnetic field, causes phase of output signal contrary, can distinguish wear particle type in fluid；Magnetic media grain is the biggest, Fiber number is the biggest, and the biggest on magnetic field impact, the amplitude of output signal is the biggest, and the sensitivity of detection is the highest.Utilize ferromagnetics and non-ferric The magnetic substance metal particle otherwise impact to former magnetic field, causes phase of output signal contrary, can distinguish wear particle type in fluid, Thus realize that signal conformance is good, reliability is high, the detection Double-pipe plug-in type structure changes twin coil fluid that signal is strong and error is little Online monitoring system.

Due to the existence of hysteresis, after ferromagnetic material is magnetized into saturation, even if cancelling externally-applied magnetic field, in material Magnetic induction still return less than zero point, need externally-applied magnetic field demagnetization.In order to prevent magnetic microparticles from entering hydraulic circuit, to pollution Sensitive Hydraulic Elements cause damage, devise demagnetization module 9, including remanent magnetism sensor and demagnetizer.ECU1 goes out according to demagnetizer At Kou, the detected value of remanent magnetism sensor controls the demagnetization intensity of demagnetizer.The demagnetization method herein used is electromagnetism demagnetization, method It is the opposing magnetic field by add suitable so that the magnetic induction in material comes back to zero point, and magnetic field intensity or electric current Must invert in order and gradually reduce.

The concrete grammar using above-mentioned supervising device to be monitored hydraulic oil is as follows:

1), the fluid in fluid pressure line 9 passes through wave filter 8, the high, medium and low frequency range that wave filter 8 is decayed in hydraulic system Fluctuation pressure, and suppression flowed fluctuation；

2), fluid enters the mechanical centrifugal module 21 separating adsorption module 2 afterwards, makes the wear particle in fluid be polymerized also Realizing initial centrifugation, the polymeric macroparticle making quality bigger gets rid of to near-wall；

3), make ferromagnetic metal polymeric macroparticle force-magnetized by magnetized module 22；

4), magnetic suck module 23 adsorbs the big microgranule of magnetized metal polymerization；

5), by electrification module 24, the non-ferromagnetic metal wear particle charged polymeric in fluid is made；

6), charged particle flows into electric adsorption module 25 with speed v subsequently, and electric adsorption module 25 is controlled to produce and speed by ECU1 The uniform magnetic field that degree v direction is vertical, charged particle is subject to be perpendicular to the Lip river logical sequence of velocity attitude and magnetic direction in segregation apparatus The effect of magnetic force, makes charged particle under this force to aluminum matter vessel wall motion, so that the non-ferromagnetic metal in fluid Wear particle " separates " out from fluid, and absorption is on tube wall.

7), after magnetic suck and electro-adsorption to enough particle concentrations, ECU1 first controls electric adsorption module 25 by electric field side To first reversely, then cancel electric field, then adsorb non-ferromagnetic metal wear particle on tube wall and start to depart from tube wall delay from static Slow-motion enters to rotate moulding module 3, and electric adsorption module 25 the most then recovers original electric field.Meanwhile, ECU1 controls magnetic suck mould Block 23 power-off, paramagnetism aluminum matter pipeline loses magnetism, and is attached to magnetic polymeric bulky grain on inner-walls of duct and will be disengaged from tube wall, electrification The power-off of module 24, ferromagnetic particle flows through electrification module 24 and electric adsorption module 25 with low speed with fluid, enters rotation moulding Module 3.Subsequently, magnetic suck module and the electrification original duty of module recovery.

8), charged nonferromagnetic microgranule and magnetized ferromagnetic particle successively enter and rotate moulding module 3, now ECU1 Controlling to flow through three-phase symmetrical electric current in three-phase symmetric winding, this electric current produces rotating excitation field in aluminum matter pipeline.Magnetized particles exists Being acted on by magnetic field force under rotating excitation field effect, and the most spirally advance, magnetic microparticles is along the magnetic line of force Direction defines a lot of acicular texture, and these acicular textures will be followed magnetic field and be spinned motion when magnetic field rotating, when motion When metal particle in acicular texture and movement locus meets with, it is combined with one another to bulky grain polymer.

9), by rotating moulding module 3, make the particle diameter of the metal particle in fluid increase form simultaneously and become elongated needle-like Structure so that the fiber number of metal particle is also greatly increased, further enhancing the sensitivity of Double-coil type detection.This two class subsequently Microgranule enters detection coil 4 with the state of low speed, high concentration, bulky grain and big fiber number in batches, and ECU1 controls exciting current and keeps The magnetic field homogeneity of detection coil 4, simultaneously because the power of test of Ferrous particles is greater than copper by the inductance of same model The power of test of granule, need ECU regulation exciting current to compensate this difference, with keep output concordance.Flow sensing Flow parameter when device 7 is for detecting measurement, for measurement result correction.

10), time in detection coil 4 without abrasive particle, there is certain fluctuation in the total null voltage of sensor, due to detection coil 4 Identical with reference coil 5 characteristic, there is no output voltage.And when abrasive particle enters detection coil, then cause sensor output voltage Change, this variable quantity is metastable.When in fluid by there being metal bulky grain, cause disturbance of magnetic field, cause producing Raw induction electromotive force.Utilize ferromagnetics and the non-ferromagnetic material metal particle otherwise impact to former magnetic field, cause phase of output signal On the contrary, wear particle type in fluid can be distinguished；Magnetic media grain is the biggest, and fiber number is the biggest, the biggest on magnetic field impact, output signal Amplitude the biggest, the sensitivity of detection is the highest.Utilize ferromagnetics and the non-ferromagnetic material metal particle otherwise impact to former magnetic field, lead Cause phase of output signal is contrary, can distinguish wear particle type in fluid.Thus realize that signal conformance is good, reliability is high, inspection Survey the Double-pipe plug-in type structure changes twin coil fluid online monitoring system that signal is strong and error is little.

11), eliminate magnetic particle magnetic by demagnetization module 9, prevent magnetic microparticles from entering hydraulic circuit, sensitive to pollution Hydraulic Elements cause damage.
