Description
Technical field
The present invention relates to oil sample pretreatment unit technical field, oil sample in particularly a kind of aircraft equipment oil contamination prevention and control
Pretreatment unit and using method thereof.
Background technology
The requirement of plane hydraulic system functional reliability is high, and when performing aerial mission, once hydraulic system operation loses
Spirit, just has the danger of fatal crass.And the pollutant in hydraulic air oil system are to cause malfunctioning main of hydraulic system operation
Factor, the pollutant in hydraulic air oil system mainly have solid particle, water, air, chemical substance and a microorganism etc., and solid
Granule is then most common, damaging effect maximum.It can make the abrasion of Hydraulic Elements accelerate, the lost of life, hydraulic performance decline, very
To making spool jam, oil filter blocks, so analyzing and controlling plane hydraulic system solid particle pollution important in inhibiting.According to
Statistics, the hydraulic system fault caused due to solid grain contamination accounts for the 60% ~ 70% of gross contamination fault, and solid particle is dirty
Dye thing not only accelerates the abrasion of Hydraulic Elements, and the gap of obturating element and aperture, make control element movement malfunctioning and cause
The system failure.It addition, the operating pressure of my army novel operational aircraft hydraulic system is higher than 14.0MPa at present, and make equipped with servo
Dynamic device, belongs to pollution pole sensory system, therefore requires higher to the cleannes of plane hydraulic system.
It is generally believed that the concentration of 5 μm left and right molecules is to cause hydraulic system alluvial and the main cause of plugging fault,
Play leading effect more than the granule density then abrasion to Hydraulic Elements of 15 μm, make with the granule density of the two size
For formulating the foundation of grade, can more fully reflect the impact on system of the different size of granule by ratio.At present, special at aircraft
Being in electromotor Oil Monitoring, the main oil contaminant preventions used is the monitoring of fluid granularity.Fluid granularity is supervised
Control utilizes automatic particle counting, is that the liquid automatic particle counter of a kind of shading, resistance or the work of electronic imaging principle measures
In liquid, the size of solid particle and quantity, be used for obtaining digital assay result to evaluate oil pollution journey used by sampling equipment
The Monitoring and Controlling means of degree.By analyzing the performance change of monitored equipment institute with lubricator (or working media) and the mill that carries
Damage microgranule situation, it is possible to obtain the lubrication of equipment and state of wear information, in order to operating mode and the prediction fault of valuator device.Low
Speed heavy duty, bad environments, move back and forth and use lubricant and rise in the equipment dynamic monitoring as dominant failure mode of wearing and tearing
Important effect.
Before fluid granularity monitoring test, involved oil sample need to carry out improving the pretreatment of monitoring accuracy, bag
Including the first step, the most hand 5min shakes up the solid particulate matter in fluid, prevents solid particulate matter to be deposited on because of gravity
Cause oil sample solid particle degree skewness bottom sampling bottle, cause fluid granularity monitored results level deviation;Second step,
Use ultrasonic washing unit to carry out the defoaming treatment of duration at least 1min, until stratification bubble rises to liquid level, take in order to eliminate
A large amount of bubbles that oil sample in sample bottle produces when the process of sampling, it is to avoid test class result is impacted by it.But it is existing
Some technology are to have the following disadvantages solving oil sample pretreatment, and one is to be only 2 ~ 3 minutes the oil cleanliness monitoring and test time,
Oil sample pretreatment time includes hand 5 minutes and ultrasound wave defoaming treatment then needs 6 minutes for 1 minute, and pretreatment time is longer, is
The twice of monitoring time.In the case of monitoring task amount is relatively big, the long problem of oil sample pretreatment time is the most prominent.Two are
Monitoring operator can not carry out other monitoring operations, impact monitoring efficiency when hand sampling bottle mixing oil sample.Three is hand mixed
Carrying out ultrasonic defoaming treatment after even oil sample again, during defoaming treatment, the solid particulate matter in oil sample still can be because of gravity
Reason precipitate downwards, cause its skewness, affect the accuracy of monitoring result.
Summary of the invention

And be fixed on magnetic agitation aggressive device;
S3, stirring: regulation magnetic agitation time control switch, magnetic agitation tumbler drives driven stirrer high speed rotating,
In driving sampling bottle, oil sample forms whirlpool and liquid stream from the bottom to top, takes up the solid particulate matter sinking down into sampling bottle bottom to oil
Sample top, it is achieved solid particulate matter even suspension in oil sample;
S4, ultrasound wave froth breaking: be connected by cable link with supersonic generator by transducer oscillator, supersonic generator produces
Raw high-frequency and high-voltage conduction is converted into vibrations mechanical energy, tapered to the output of cleaning chamber internal radiation, by cleaning chamber
Liquid medium transfers its energy in the oil sample in sampling bottle, so that the fluid in sampling bottle is realized bubble by ul-trasonic irradiation
Eliminate.
In step S3, the direction of rotation of magnetic agitation aggressive device and rotary speed are cyclically-varying.
The invention have the advantages that
1, in oil sample, solid particulate matter blending efficiency is high, and suspended dispersed is uniform.Heretofore described aircraft equipment oil contamination
In prevention and control oil sample pretreatment unit use high speed magnetic stirring, sampling bottle hand with tradition with mixing oil sample method compared with, can
To form the whirlpool stablizing high speed rotating in oil sample, the solid particulate matter bottom drive floats, plays the purpose of mixing.Magnetic force
Direction of rotation and the rotary speed of stirring aggressive device are cyclically-varying, can drive direction of rotation and the rotation of driven stirrer
Rotary speed synchronizes in cyclically-varying, and blending efficiency is higher, and because without the hand sampling bottle of operator, improves pretreatment
The automaticity of process, in the case of operation multiple stage oil cleanliness monitoring device works simultaneously, pretreatment efficiency is high
Advantage becomes apparent from.
2, oil sample pretreatment unit in aircraft equipment oil contamination prevention and control of the present invention, same at high speed magnetic stirring
Time, due to the both sides in cleaning chamber, it is respectively equipped with two groups of several transducer oscillators each, the fluid in sampling bottle can be made to be subject to
Ul-trasonic irradiation realizes bubble and eliminates.Compared with traditional oil sample pretreatment time, use aircraft equipment of the present invention oil
In liquid pollution prevention, oil sample pretreatment unit carries out ultrasonic froth breaking, significantly again without waiting after solid particulate matter suspends uniformly in oil sample
Shorten oil sample pretreatment time, and avoid because during single ultrasound wave defoaming treatment, solid particulate matter sinks to causing
Oil sample disperse once again uneven.
