Description
Technical field
The utility model relates to the machine oil detection device, is specifically related to monitoring and the detection device of lubricant oil in the machinery.
Background technique
In the machine operation device, viscosity is the most important quality index of lubricant oil.The measuring of internal friction when viscosity is Fluid Flow in A is to weigh oil product resist mobile ability under specified temp.The lubricant oil that selecting properly viscosity is suitable can be given full play to the effect of lubricant oil, and the bearing of assurance retarder, gear-box, bath lubrication etc. is in reliable and stable working condition.If viscosity is excessive, can cause the engine start difficulty, the consumption that increases fuel oil reduces engine power; Viscosity is too small, can reduce the oil film enabling capabilities, makes between the rubbing surface to keep continuous lubricating layer, increases component wear.Therefore for process units, detect regularly that used oil body in the operational outfit changes and lubricant oil in the content of iron filings, whether judgment device needs is changed oil, and " peace, steady, long, full, the excellent " operation that guarantees equipment is had very important meaning.Determining method and the method for expressing of viscosity are a lot.Commonly used have Redwood viscosity, saybolt viscosity, Engler viscosity, a kinematical viscosity etc.Conversion between various viscosity can draw approximative value by the method conversion of tabling look-up usually.China measures the kinematical viscosity of lubricant oil usually according to GB/T265-88 " petroleum products kinematical viscosity determination method and kinetic viscosity numeration ", domestic many kinematical viscosity testers are also produced according to GB/T265-88 fully.
Viscosity is an amount in the fluid mechanics, also is important parameter in the materials science simultaneously, and the theoretical research to it on mechanics is a lot, more is that research viscosity is on the impact of physical property on materials science.The development that has jointly promoted viscosity measurement is used in the research of two subjects.After the 17th century, newton law of viscosity proposed, viscosity measurement had just had theoretical foundation.Because hydromechanical complexity, the adhesive characteristics that reaches different temperatures between the different fluid differs greatly, and various countries' standard viscosity liquid is all different so far.So the method for viscosity measurement also has a lot, their difference is very large.Be summed up and always have 6 kinds of methods.
(1) rotary process
Rotary process is the most general method of current viscosity measurement, observes newton law of viscosity fully, and rotational viscosimeter also is commercialization viscosimeter the earliest.1934, Brookfield sold his First dial type viscosimeter.After this, he has founded a company with father and brother and the dial type viscosimeter has been put on market, and this product became the standard of world's viscosimeter afterwards.Many countries have also all developed like product, such as the B instrument of Tokyo meter viscosity device, the V200O series of U.S. CANNON company, the NDJ series of China Shanghai balance equipment factory, the NDJ99 type of Chengdu Instruement Factory, France, Britain, Australia etc. also have like product to put on market.In speed control formula rotational viscosimeter, except cloth formula viscosimeter, also have inner-rotary type, evolute viscosimeter.By literature search, in addition also have Stomer viscosimeter, the ETS of U.S. CANNON company---the 100OThormer Stomer rotational viscosimeter etc. of proof stress formula.Along with the development of electronic technology, rotational viscosimeter gradually by dial type to digital transition, the gentle precision of the Automated water of viscosimeter is more and more higher.
(2) capillary tube method
Capillary tube method also is the current more general a kind of method of using, particularly in the low-temperature measurement field.In 19th century, French scientist has proposed the poiseuille's law of capillary tube measurement viscosity, has established the theoretical foundation of capillary tube measurement viscosity.Along with the continuous improvement of people to capillary viscosimeter, capillary viscosimeter has obtained good development, and wherein the gravity-type wool type Guan Fazhong of ISO3105 just has 19 kinds of viscosimeters.Many robot device adopt specially designed capillary viscosimeter, broken pipe formula such as the straighttube-type of U.S. CANNON company, French ISL company and Britain STANHOPE-SETA company, these capillary viscosimeters meet pool formula law in design, also belong to the viscosimeter among the ISO3150.Domestic about the capillary viscosimeter automatic survey research and the exploitation of product just began starting before 20 years, the eighties, Quanzhou, Fujian Electronic Instruments Plant developed domestic first generation product, existing many launch products so far, and having updated repeatedly.Nearly 10 also have some units to develop, and launch products is arranged, and majority is applied to petrochemical industry, and what have is applied to medicine and blood viscosity analysis.
(3) viscosity agar diffusion method
The viscosity agar diffusion method is a kind of special case of capillary tube method.In order to accelerate flow velocity, save measurement time, capillary pipe length shortens, and caliber enlarges, and makes short-tube type or opening flow cup.Viscosity agar diffusion method measuring phase is simple, is convenient to execute-in-place and is widely adopted.Grace cup etc. is examined by Ford cup and Japan such as Engler viscometer, the U.S..China is with reference to No. 4 cups of Ford, and that makes after slightly changing that we commonly use is coated with-4 glasss.It can be converted into kinematical viscosity to the time t (second) that liquid flows out flow cup by formula.
(4) Constructional Elements Using Falling Methods
At present, three kinds of viscosimeters are arranged in the Constructional Elements Using Falling Methods, that is: fall-ball type, the pillar that falls, bubble type, wherein falling ball viscometer is more common.Falling ball viscometer is again the Hoepler viscosimeter, is named in a chemist of German HAAKE company, and he has invented this viscosimeter in the thirties in 20th century.This is a kind of simple and accurate viscosimeter, is applicable to from gas to transparent or semitransparent fluid low, medium viscosity.So far still have its very consequence in industry and research field, in particular for measuring low viscous Newtonian fluid, such as human plasma, beverage, beer etc.Falling ball viscometer only has the product of German HAAKE company in the market, and is more rare in China.
(5) vibratory drilling method
The vibration ratio juris is: can be subject to the anticoagulation of fluid when being in the object vibration in the fluid, the size of this effect is relevant with the viscosity of fluid.Vibro Viscometer commonly used has ultrasonic viscometer, and its prober has a shell fragment.When agitated by impulsive current, shell fragment produces the mechanical vibration of ultrasonic wave range, and when shell fragment was immersed in the sample, the amplitude of shell fragment was relevant with the viscosity of sample and density.Under the feelings of known density are wished, can try to achieve viscosity numerical value from the amplitude data of measuring.The SV series sine wave oscillations formula viscosimeter of Japan AND company just is based on this principle design.Substantially do not have on the Chinese market, and the ultrasonic viscometer price comparison is expensive, not too suits large area to popularize.
(6) vibration agar diffusion method
The vibration agar diffusion method is to measure the among a small circle main method of viscosity of low viscosity, and this method just proposed in the thirties in last century.But because the motion of vibration cup is very complicated, and mathematical model is difficult to set up accurately, so do not derive accurately viscosity calculations equation.The fifties, the someone set up the viscosity algorithm that contains correction factor in succession, although there is not accurate mathematical model, the measurement result precision of viscosimeter is very high.2000, U.S. Auburn University announced that externally they have successfully developed the vibration cup viscosimeter based on mathematical models, and this viscosity theory of algorithm precision reaches 0.01%, but this instrument of Chinese market is few at present, can not satisfy the widely market demand.
The size of water ratio of lubricating oil determines the moisture damage oil film, reduce lubricity, the wearing and tearing of aggravation fastness parts, can react with oil product, formation acid, colloid and greasy filth water can be separated out the additive in the oil, reduce the usability of oil product, make the mobile variation of oil product during low temperature, the metallic material of burn into corrosion equipment, lubricant oil is thinning during high temperature releases, so temperature also is an extremely important index when detecting.
In industrial enterprise, at present whether lubricant oil will be changed, and the machine-man only relies on subjective sensation, perhaps relies on machine run how long to be judged, so very science not.In addition, whether exist iron filings very large to Lubrication Properties in the lubricant oil, just can keep good greasy property if in time remove iron filings, can design a kind of energy automatic monitoring lubricating oil viscosity, and iron filings content in the detection lubricant oil, and timely oil change more, keep that lubricant oil has good greasy property in the gear-box.This kind detection facility just at present a lot of enterprises thirst for.
