According to an aspect of the present invention, be trapped in the abrasive dust in oil sample on filter membrane by filter.
According to an aspect of the present invention, filter membrane has preset aperture.
According to an aspect of the present invention, the pipe of test system is all cleaned in detergent line before and after the whole test process
Road and filter membrane.
According to an aspect of the present invention, imaging device can be CCD imaging devices.
On the other hand, the present invention provides a kind of method of testing for testing wear debris topography in oil sample, and it includes：First behaviour
Make, oil sample is diluted using detergent line and the pipeline and filter membrane of test system is cleaned；Second operation, is filtered using filter
The oil sample of dilution, the abrasive dust in the oil sample of dilution is trapped within filter membrane；With the 3rd operation, gathered by imaging device and cut
The pattern of the abrasive dust for staying.
According to another aspect of the present invention, the above method also includes：The pattern of the abrasive dust to gathering is analyzed.
Compared with prior art, beneficial effects of the present invention are as follows：
(1) conclusion of test system of the invention, can quickly understand the state of wear of equipment, judge equipment fault
Reason, pre- measurement equipment situation, this is transported in mine, steel, petrochemical industry, Rail Highway, the application in the industry such as Aero-Space
Meaning greatly, also brings along huge economic benefit；
(2) test system of the invention obtains abrasive dust by the principle of filter membrane method, is not limited to iron or ferrous metal, application
Scope is wide.
Brief description of the drawings
Fig. 1 is most popular ferrograph analyzer in the prior art.
Fig. 2 is the test system for testing wear debris topography in oil sample of the invention.
Specific embodiment
The present invention is described in further detail with specific embodiment below in conjunction with the accompanying drawings, described specific embodiment is only right
The present invention is explained, and is not intended to limit the invention.
According to the embodiment of the present invention, the present invention provides a kind of test system for testing wear debris topography in oil sample,
Wherein, including：Filter, with the filtering membrane filtration oil sample in filter；Detergent line, surveys for diluting oil sample and cleaning
The pipeline and filter membrane of test system；And imaging device, the pattern for gathering abrasive dust in oil sample.Filter membrane in filter sets
Put in filter, play a part of to filter oil sample, the abrasive dust in oil sample can be made to be trapped on filter membrane, so as to carry out down
The abrasive powder analysis of one step.
According to the embodiment of the present invention, be trapped in the abrasive dust in oil sample on filter membrane by filter.
According to the embodiment of the present invention, filter membrane has a preset aperture, the aperture of such as filter membrane can be 15 μm or
It is smaller.However, considering the condition of filtering oil sample process, such as size of filtering rate and required abrasive dust etc., filter membrane
Preferably 15 μm of aperture.
According to the embodiment of the present invention, detergent line all cleans test system before and after the whole test process
Pipeline and filter membrane.
According to the embodiment of the present invention, imaging device can be CCD imaging devices.
According to another implementation of the invention, the present invention provides a kind of test for testing wear debris topography in oil sample
Method, it includes：First operation, dilutes oil sample and cleans the pipeline and filter membrane of test system using detergent line；Second behaviour
Make, using the oil sample of filter filtering dilution, the abrasive dust in the oil sample of dilution is trapped within filter membrane；Operated with the 3rd,
The pattern of the abrasive dust being trapped is gathered by imaging device.In the second operation to the 3rd operation, by air pressure, pump, the group of valve
Close work and realize automatic cleaning, the diaphragm of filter membrane is placed in image space by automatic fitration automatically.For example, as shown in Fig. 2
, be extracted into oil sample 1 in filter with pump 2 by the filter process in three operations, and the filter membrane 3 ' in filter is by oil sample 1
Abrasive dust dams to get off.After above method of testing is completed, in addition it is also necessary to which the pattern of the abrasive dust to being trapped further is counted, point
Analysis, classification judges, finally provides the producing cause and process of different abrasive dusts, and oil sample failure cause, or oil sample is potential
Failure risk.For example, the different shape according to abrasive dust analyzes the producing cause of different abrasive dusts, such as sheet abrasive dust is because machinery sets
What standby fatigue was produced, thread and crescent shape abrasive dust be due to the cutting of plant equipment produce etc..According to the difference of abrasive dust
The component of color analysis difference abrasive dust, such as red abrasive dust is typically copper, and ferrous metal is typically iron, and white metal is typically
Aluminium or silver etc..The method can by various metals and less than filtering membrane aperture abrasive dust collect, and can by into
As be imaged for the pattern of these abrasive dusts by device, this can comprehensively and intuitively analyze the pattern of these abrasive dusts, so as to comprehensively divide
The state of whole equipment is analysed, whether such as equipment have whether abrasion, equipment are corroded, or whether equipment is aging etc., therefore energy
Enough further to take measures, such as more oil change suitably adds some preservatives, position of on-call maintenance ageing equipment etc.,
And cycle of more oil change is can determine, scientifically use equipment.
The above method also includes：The pattern of the abrasive dust to gathering is analyzed.Analysis process can by manually carrying out,
Can be by software analysis, for example, software can rule of thumb be write by domestic and international top friction wear expert.The software
The pattern of abrasive dust can in detail and be comprehensively analyzed, the wear reason that can not only go out equipment according to the shape analysis of abrasive dust is for example
Lubricating oil fails or equipment aging etc. in itself, additionally it is possible to color according to abrasive dust come analytical equipment in any metal damage
Lose seriously, so that the state of analytical equipment, therefore, it is possible to according to analysis result, take measures to carry out to the protection of equipment with maximum
Prevent to degree serious consequence such as device damage etc. from occurring.
Principle for testing the test system of wear debris topography in oil sample is as follows：Oil sample to be measured is diluted, and using with one
Set aperture filtering membrane filtration dilution oil sample to be measured be trapped on filter membrane with by the abrasive dust in oil sample to be measured, by CCD into
As device collection is trapped in the pattern of abrasive dust on filter membrane, and stored using morphology analysis module and analyze the shape of these abrasive dusts
Looks.
The conclusion of test system of the invention, can quickly understand the state of wear of equipment, judge that equipment fault is former
Cause, pre- measurement equipment situation, this is transported in mine, steel, petrochemical industry, Rail Highway, the application meaning in the industry such as Aero-Space
It is adopted very big, also bring along huge economic benefit.
Test system of the invention obtains abrasive dust by the principle of filter membrane method, is not limited to what is be made up of iron or ferrous metal
