Description
Technical field
The utility model relates to carrying with lubricant pollution degree determinator that lubricating oil internal contamination degree is measured.
Background technology
Along with the develop rapidly of technology in the industries such as machine, electronics, need a kind of prevention technique or the suitableeest state judgment technology urgently in recent years, be used to prevent the chance failure and thereby the mishap that causes of machine and various systems.These technology are except being applied in mechanical fields such as automobile, aircraft, in the integrated mills such as the institute that also can be applicable to generate electricity, system iron institute, petrochemical plant.
By the dustiness in the Measurement and analysis lubricating oil, can judge the abrasion condition of machine system, this technology mainly is to realize by the amount of the abrasion particle in the lubricating oil in the machine system and other foreign material dustinesss of invading from the outside are analyzed, thereby the technology type of white blood cell in itself and the quantitative measurment blood in human body in liquid and erythrocytic number diagnosis health seemingly, therefore also can be called the machine health diagnosis.
Under normal conditions, by to the measurement of dustiness and, mainly be divided into quantitative measurment and observational measurement to the technology that state is judged.Quantitative measurment is according to the time of machine run the generating capacity of the abrasion particle of machine significant points to be measured, observational measurement be the composition that is used to analyze abrasion particle, abrasion particle size variation, external contamination particle intrusion whether, whether the rotten generation of machine significant points reach the degree of oxidation situation.At first whether the viability of machine system is judged by above Measurement and analysis, thereby and can be forecast the possibility that machine system damages in advance the migrate attribute analysis of wear phenomenon.Thereby and grasp the main wearing terrain of the existing machine system that is just using by abrasion condition that continuous analysis took place.These results can be used as in next time and transform the basic design data of machine system design and adopted.
Below the device that is mainly used in quantitative measurment lubricating oil internal contamination degree is described.It mainly comprises the judgement machine of the off-line state of analytic sample--spectrum analysis device and particle calculator.The spectrum analysis device is used to measure material composition and the quantitative levels of having polluted in the lubricating oil, in the state that now is mainly used in aircraft engine etc. is judged.The advantage of this measuring appliance is accurately to measure dustiness, but it can not learn the information of relevant polluter size aspect, and the size of the contaminant particles of its energy measurement approximately is confined to 5-20 μ m.Particle calculator is used to measure size, degree of scatter and the gross contamination degree of the contaminant particles that lubricating oil contains, but pollution level it can't be measured when serious, also can't understand the information of relevant contaminant particles composition.For example, at United States Patent (USP) bulletin No.4, disclosed Ferrography machine in 187,170, the BrP bulletin disclosed RPD of No.8121183 (rotation ion deposition) machine, and PQ (particle quantification) machine etc.What Ferrography and RPD adopted in the above technology is after oily internal contamination particle is fixed on transparent glass surface, utilizes size, form, color of optical microscope or electron microscopic analysis contaminant particles etc.Can know basic reason and the present situation that the lubricating oil internal contamination takes place by above contaminant particles specificity analysis.But different results can appear because of analyst's difference in above technology.
The machine of quantitative measurment lubricant pollution degree has QDM (quantitatively relic detector), magnetic chip detector, FCM (fluid state detector) etc.QDM induces the contaminant particles in the oil to make it to be deposited on specific sensor surface with magnetism, and the voltage-pulsating current that passes through thus to be produced is measured dustiness, but it can only measure the contaminant particles greater than 100 μ m.The magnetic chip detector be in lubricating oil behind the injection magnetic material at the normal magnetic contaminant particles of magnetic surface attachment, with the naked eye wait method periodic analysis magnetic material afterwards, its advantage is simple at the scene, but the normal magnetic particle attached to the magnetic surface is greater than 100 μ m, and can not detect the nonmagnetic material contaminant particles.
At above situation, a kind of " online determination methods of abrasion particle and device in the lubricating oil " disclosed among the korean patent application No.870-3498.Its main points are to measure the light quantity of contaminated particle blocking-up during by lubricating oil at light, and the amount of particle in the test portion oil is measured.And by Permanent magnet being set on lubricating oil sample container top, thereby the normal magnetic particle of lubricating oil inside can concentrate on one side, in optical channel, got rid of, measured light quantity afterwards, can be measured the dustiness of normal magnetic composition in the gross contamination degree so in addition.But such method can produce following problem, the first, and utilize permanet magnet that the small normal magnetic particle that disperses in the oil is induced toward the permanet magnet aspect, this needs the very strong magnetite of magnetic, and therefore the volume with this relevant part can become big.The second, during lubricant applications said method that the scene is used, lubricating oil sample measuring box inside is oil just, also has a lot of air bubbles coexistences.According to above method, it is contaminant particles that the air bubble when with light being the measurement medium in these oil tends to be mistaken as, and the result who measures probably is than actual dustiness height.The 3rd, these methods are situations about being blocked by opaque contaminant particles when only considering that light passes through oil, but when measuring in real time, because the variation of oil viscosity causes the disconnected effect of photoresistance also different, therefore abovely change the measurement that can directly influence dustiness.
As mentioned above, in the method for quantitative measurment lubricating oil internal contamination particle, at first require above-mentioned technology to use, require directly to measure, and must possess the ability of accurate measurement at the operation field that machine is just turning round in real-time mode.Next is also to require energy qualitative analysis contaminant particles except the quantitative dustiness of measuring contaminant particles.This is because the main machine part in the machine system is made up of the ferrous materials of normal magnetic or the nonmagnetic material material of aluminium alloy and copper etc., after being worn, these machine critical pieces are converted into the contaminant particles in the oil, and serious by this dustiness being measured the component wear situation that just can grasp which position in the machine system at once effectively.
By above-mentioned traditional lubricant pollution degree measuring method, the magnetisable material dustiness in can't observational measurement lubricating oil and the dustiness of non-magnetic material, and volume is bigger, is unfavorable for carrying out work at operation field.
