U1461U1461
Opfindelsen angår et apparat til konstatering af vandindhold i olie og er af den art, som er angivet i indledningen til krav 1. Der kendes apparater, som er indrettet til at rense olien for vand ved at underkaste olien en passende opvarm-5 ning i så lang en periode og med en sådan effekttilførsel, at al vandet fordampes, men det har vist sig, at sådanne apparater er meget dyre i drift og ikke er så effektive, som det er ønskeligt. Ved driften af større maskiner og motorer, navnlig skibsmaskiner og gear 1 skibe, er oliens 10 renhed af allerstørste betydning, og det volder ingen vanskeligheder at filtrere forskellige urenheder fra såsom metalstøv, medens det ikke er muligt ved filtrering at fjerne vand fra olien. Imidlertid betyder selv et forholdsvis ringe indhold af vand i olien en meget stor risiko for, at 15 svigtende smøring forårsager totalt sammenbrud af maskineriet, og man må derfor drage omsorg for, at vandindholdet i olien hele tiden holdes under et givet niveau. I USA patent nr. 1.901.010 er beskrevet et apparat, som skulle anvendes til fjernelse af vand i olien, men et sådant apparat er meget 20 dyrt i drift, og da man på den anden side sædvanligvis i større maskininstallationer har indbygget en centrifuge, hvorved man med sikkerhed kan fjerne vandet fuldstændigt fra olien og endda med. et relativt lavt energiforbrug, tagér opfindelsen sigte på at udforme et apparat, som ikke er ind-25 rettet til at fjerne vandet fra olien, men blot er indrettet til at afdampe så meget vand fra olien, at man derigennem får et mål for vandindholdet i olien og kan få etableret en alarm, så snart vandindholdet overskrider en bestemt værdi, som ligger under den grænse, hvorved vandindholdet 30 bliver farligt, hvorefter centrifugeringen sættes i gang.The invention relates to an apparatus for determining the water content of oil and is of the kind set forth in the preamble of claim 1. There are known apparatus which are adapted to purify the oil from water by subjecting the oil to a suitable heating in such a manner. for a long period of time and with such power supply that all the water is evaporated, but it has been found that such apparatus is very expensive to operate and is not as efficient as desired. In the operation of larger machines and engines, in particular ship machinery and gear 1 ships, the purity of the oil 10 is of the utmost importance, and it is not difficult to filter out various impurities such as metal dust, while it is not possible by filtration to remove water from the oil. However, even a relatively low content of water in the oil poses a very high risk that 15 failing lubrication causes a complete breakdown of the machinery, and care must therefore be taken to keep the water content of the oil constantly below a given level. United States Patent No. 1,901,010 discloses an apparatus to be used for removing water in the oil, but such an apparatus is very expensive to operate, and since, on the other hand, a centrifuge is usually built into larger machine installations, whereby one can safely remove the water completely from the oil and even with it. In a relatively low energy consumption, the invention aims to provide an apparatus which is not adapted to remove the water from the oil, but is merely designed to evaporate so much water from the oil as to thereby obtain a measure of the water content of the oil. the oil and may cause an alarm to be established as soon as the water content exceeds a certain value which is below the limit whereby the water content 30 becomes dangerous, after which the centrifugation is started.
Det drejer sig om et meget lavt vandindhold, og målingen skal derfor være følsom for små vandmængder. Fra USA patent nr. 2.571.470 kendes et apparat, som er indrettet til at måle indholdet af flygtige stoffer i en væske, men dette apparat 35 er baseret på måling af viskositetsændringer, der imidlertid langt fra giver den følsomhed og nøjagtighed, som er nødvendig, for at man med sikkerhed kan fastslå, hvornår en olie er uegnet til anvendelse i et smøresystem. Der kendes tillige 2 141461 et-apparat til konstatering af vandindhold i olie, hvilket apparat er forsynet med en oliebeholder, hvortil olie tilføres kontinuerligt, og hvori der er anbragt et termostatstyret varmelegeme, som bevirker en fordampning af vand fra 5 overfladen af den oliepøl, som til enhver tid findes i beholderen. De dannede vanddampe fortættes på en over beholderen anbragt afkølingskegle med nedadvendende spids, hvorfra vandet ledes ned til et afløbsror og føres til organer for måling af vandmængden. Et sådant apparat kan dog bevirke, 10 at der ved visse rumtemperaturer sker en fortætning på beholderens sider i stedet for på afkølingskeglen, så vanddråben løber direkte ned i oliepølen, hvorved den mængde vand, der skal måles, ikke bliver korrekt, samtidig med at de tilbageløbende vanddråber giver anledning til opsprøjtning af 15 olie, således at oliedråber kan sætte sig på keglen og derfra føres ud til måleorganerne, så måleresultatet yderligere forvanskes. En termostatstyret regulering af den effekt, der tilføres varmelegemet, har endvidere den væsentlige ulempe, at reguleringen virker for trægt på grund af metal-20 legemets store varmekapacitet.This is a very low water content and therefore the measurement must be sensitive to small quantities of water. United States Patent No. 2,571,470 discloses an apparatus adapted to measure the content of volatiles in a liquid, but this apparatus 35 is based on measurement of viscosity changes, which, however, far from provide the sensitivity and accuracy needed , so that one can safely determine when an oil is unsuitable for use in a lubrication system. There is also known an apparatus for detecting water content in oil, which apparatus is provided with an oil container to which oil is supplied continuously, and in which a thermostatically controlled heater is provided, which causes evaporation of water from the surface of the oil pool. which is present in the container at all times. The water vapors formed are condensed on a downwardly extending cooling cone placed above the container, from which the water is directed down to a drain pipe and passed to means for measuring the amount of water. However, such an apparatus can cause a condensation at certain sides of the container rather than on the cooling cone to cause the water drop to flow directly into the oil pool, thereby not correcting the amount of water to be measured, Recirculating water droplets give rise to the spraying of 15 oil, so that oil droplets can settle on the cone and from there are discharged to the measuring means to further distort the measurement result. Furthermore, a thermostatically controlled control of the power supplied to the heater has the major disadvantage that the regulation acts too sluggish due to the large heat capacity of the metal body.
Ved ifølge opfindelsen at udforme et apparat af den angivne art.således som angivet i den kendetegnende del af krav 1, opnår, man at få en velkontrolleret oliemængde ført ind i et fordampningskammer, der med fordel kan være ganske snæ-25 vert, og det har vist sig, at man ved at tilføre en konstant varmemængde til legemet og lade olien afkøle dette kan opnå en sådan effektiv stabilisering af legemets temperatur og dermed over en given periode få en helt eksakt fordampning af vandet fra olien, at den vandmængde, der fordampes, giver 50 et klart, korrekt og entydigt udtryk for det vandindhold, der findes i olien, og dermed får man muligheden for at slå alarm, så snart vandmængden overstiger en given grænse, hvorefter man kan sætte centrifugen i gang for at drive vandet ud af olien. Den fuldstændige adskillelse mellem fordampnings-35 og fortætningsrummet sikrer imod ulemper af ovennævnte art, og det har vist sig, at den måde, hvorpå man styrer den gennem apparatet passerende oliemængde i forbindelse med styringen uue i 3 af temperaturen af det fordampningsrummet omgivende legeme medfører en overordentlig stor præcision i måleresultatet.By designing an apparatus of the kind specified according to the characterizing part of claim 1, one obtains a well-controlled quantity of oil introduced into an evaporation chamber which can advantageously be quite narrow, and the It has been found that by adding a constant amount of heat to the body and allowing the oil to cool, this can achieve such an effective stabilization of the temperature of the body and thus, over a given period of time, to obtain a very precise evaporation of the water from the oil, that the amount of water evaporated. , 50 gives a clear, correct and unambiguous expression of the water content contained in the oil, thereby giving you the opportunity to sound an alarm as soon as the water volume exceeds a given limit, after which you can start the centrifuge to drive the water out of oil. The complete separation between the evaporation chamber and the condensation compartment ensures against drawbacks of the above-mentioned type, and it has been found that the way in which the amount of oil passing through the apparatus in connection with the control uue in 3 of the temperature of the evaporation chamber surrounding the body results in a extremely high precision in the measurement result.
Samtidig er apparatet overordentligt enkelt såvel i konstruktion som betjening. Det er så at sige selvjusterende, 5 idet overløbsventilen sørger for at regulere den gennem for-dampningskammeret strømmende oliemængde, således at afkølingen, der fremkaldes af olien, bliver tilstrækkelig til at holde legemets temperatur konstant og dermed sikre den rigtige fordampning. Den olie, som skal kontrolleres, har 10 sædvanligvis en temperatur på omkring 50°C, og for at opnå en passende fordampning skal olien, hvis vandindholdet er under 1$, under passagen af kammeret hensigtsmæssigt opvarmes til omkring 120°C og ved større vandindhold kun opvarmes noget mindre, ned til omkring 105°C for at undgå overkogning.At the same time, the appliance is extremely simple in both construction and operation. That is to say, self-adjusting, 5 since the overflow valve provides for regulating the amount of oil flowing through the evaporation chamber so that the cooling induced by the oil becomes sufficient to keep the body temperature constant and thus ensure proper evaporation. The oil to be controlled is usually at a temperature of about 50 ° C, and in order to obtain a suitable evaporation, the oil, if the water content is below 1 $, during the passage of the chamber is conveniently heated to about 120 ° C and at a higher water content. only slightly heated, down to about 105 ° C to avoid overcooking.
15 Når man tilfører en konstant effekt, opnår man, at der med stigende vandindhold forbruges en stigende effekt til fordampning af vandet, hvorved temperaturen i fordampningskammeret falder til den ønskede værdi. Det er endvidere vigtigt, at det vand, som er fordampet, føres ud til en særskilt kon-20 densator, som arbejder helt uafhængigt af fordampning skammenet for derved at undgå nogen gensidig påvirkning mellem de to funktioner.When a constant effect is applied, one obtains that with increasing water content an increasing effect is consumed for evaporation of the water, whereby the temperature of the evaporating chamber drops to the desired value. Furthermore, it is important that the water evaporated is discharged to a separate condenser which operates completely independently of the evaporation sham network, thereby avoiding any mutual influence between the two functions.
Konstateringen af den pr. tidsenhed udstrømmende vandmængde kan foregå på vilkårlig hensigtsmæssig måde, men ifølge op-25 findelsen er det endvideré hensigtsmæssigt at udforme apparatet som angivet i krav 2, idet der er tale om ret små vandmængder, som vil komme ud af kondensatoren i form af enkelte dråber, og det er således let at konstatere tidsintervallerne mellem dråberne, hvilke tidsintervaller direkte 30 giver et mål for den i olien indeholdte vandmængde. Por at opnå den meget enkle og sikre styring af legemets temperatur kan apparatet endvidere ifølge opfindelsen være udformet som angivet i krav 3.The finding of the per. a unit of flow of water can be carried out in any convenient manner, but according to the invention it is further appropriate to design the apparatus as claimed in claim 2, since these are quite small quantities of water which will come out of the condenser in the form of single drops, and it is thus easy to ascertain the time intervals between the drops, which time intervals directly give a measure of the amount of water contained in the oil. Furthermore, in order to achieve the very simple and safe control of the body temperature, the apparatus according to the invention can be designed as claimed in claim 3.
Opfindelsen skal i det følgende beskrives nærmere i forbln-35 delse med tegningen, hvor 4 141461 fig. 1 viser et apparat ifølge opfindelsen set fra siden, fig. 2 viser et snit efter linien II-II i fig. 1, fig. 3 viser et snit efter linien III-III i fig. 1, og fig. 4 viser et snit efter linien IY-IV i fig. 3.The invention will now be described in more detail with reference to the drawing, in which 1 is a side view of an apparatus according to the invention; FIG. 2 shows a section along line II-II in FIG. 1, FIG. 3 shows a section along line III-III in FIG. 1, and FIG. 4 shows a section along the line IY-IV in FIG. Third
5 I fig. 1 ses et apparat ifølge opfindelsen bestående af en kasse 1, der indeholder et legeme 2 med stor varmekapacitet og er anbragt på siden af et panel, der ligeledes består af varmeledende materiale. I fig. 2 ses et snit gennem panelet -3» hvoraf det fremgår, at dette panel indeholder en lodret 10 kanal 4-, som forneden udmunder i en tilførselsstuds 5 for olie. Foroven er kanalen 4 tilsluttet en tværgående kanal 6, der igen er tilsluttet en lodret kanal 7» som forneden har en afløbsstuds 8 for olie. Den tværgående kanal 6 er til-, sluttet en drøvleventil 9, hvorfra der fører en tilløbskanal 15 10-.lodret nedefter, hvilken tilløbskanal er tilsluttet en tværgående kanal 11, der gennem et kort isoleret rørstykke 12 (se fig. 4) fører ind til en tilførselskanal 13 i legemet 2. Fra denne tilførselskanal fører en forbindelseskanal 14 til en indløbsåbning 14a i et fordampningskammer 15 ved 20 den øverste ende af dette, og kanalen 14 fører endvidere til en overløbsventil 16 med en åbning 16a, der er indrettet til at lukkes mere eller mindre ved hjælp af en bimetal-fjeder 17, som er fastgjort til legemet 2.5 In FIG. 1 shows an apparatus according to the invention consisting of a box 1 which contains a body 2 with high heat capacity and is located on the side of a panel which also consists of heat conducting material. In FIG. 2, a section through the panel -3 is shown, showing that this panel contains a vertical channel 4, which opens below into an oil supply nozzle 5. At the top, the channel 4 is connected to a transverse channel 6, which in turn is connected to a vertical channel 7 »which has a drain outlet 8 for oil below. The transverse duct 6 is connected to a throttle valve 9, from which a supply duct 15 10 is vertically downwards, which inlet duct is connected to a transverse duct 11 leading through a short insulated pipe piece 12 (see Fig. 4). a supply duct 13 in the body 2. From this supply duct, a connecting duct 14 leads to an inlet opening 14a of an evaporation chamber 15 at the upper end thereof, and the duct 14 further leads to an overflow valve 16 with an opening 16a arranged to close. more or less by means of a bimetal spring 17 which is attached to the body 2.
Fordampningskammeret 15 har en skråt forløbende nedløbsplade 25 18, der, som det fremgår af fig. 3 og 4, er udformet således, at et antal tværstykker i midten danner en zigzagformet ned-løbsbane for olien. Ved den nederste ende af fordampningskammeret 15 findes en olielås 28, som spærrer for vanddampe og ender i en afløbskanal 20 for olien, og denne udmunder 30 umiddelbart over den nederste del af bimetalfjederen 17 således, at denne påvirkes af den udstrømmende olie.The evaporation chamber 15 has an inclined downwardly sloping plate 25 which, as can be seen in FIG. 3 and 4, are formed such that a plurality of cross sections in the middle form a zigzag-shaped runway for the oil. At the lower end of the evaporation chamber 15 is an oil lock 28 which blocks water vapors and ends in a drain channel 20 for the oil, which opens 30 immediately above the lower part of the bimetal spring 17 so that it is affected by the flowing oil.
141461 5 I den øverste del af legemet 2 findes en afgangsåbning 21 for vanddamp, og denne fører gennem en isoleret ledning 22 (se fig. 1) til panelet 3, hvor den udmunder i.to indbyrdes forbundne lodrette kanaler 23, der tjener som kondensator, 5 idet de forneden har .en falles udmunding 24 (se fig. 1 og .In the upper part of the body 2 there is an outlet vapor 21 for water vapor, and this leads through an insulated conduit 22 (see Fig. 1) to the panel 3, where it opens into two interconnected vertical channels 23 serving as a capacitor. 5, having at the bottom one opening mouth 24 (see Figs. 1 and.
3), hvorfra det kondenserede vand kan løbe ud dråbevis.3) from which the condensed water can flow out dropwise.
Umiddelbart under indløbet. 24 er der anbragt et par elektroder 25 på en sådan måde, at en dråbe, . der falder ned meliem disse elektroder, vil tilvejebringe en kortvarig overgang 10 mellem disse elektroder, og denne overgang^kan da benyttes på vilkårlig hensigtsmæssig måde til en konstatering af dråbens passage og således til en måling af tidsintervallerne mellem dråberne. *Immediately below the inlet. 24, a pair of electrodes 25 are arranged in such a way that a drop,. falling down between these electrodes will provide a short-term transition 10 between these electrodes, and this transition may then be used in any convenient manner for detecting the passage of the droplet and thus for measuring the time intervals between the droplets. *
Kassen 1 er tilspidset nedadtil og har et lille stykke over 15 den nederste spids en afløbsåbning,26 for olie, hvilken olie delvis kan komme fra overløbsventilen 16 og delvis fra kanalen 20. I legemet 2 er. der indbygget varmelegemer 27, som på vilkårlig hensigtsmæssig måde får tilført en konstant energi.The box 1 is tapered downward and a little over 15 the lower tip has a drain opening, 26 for oil, which oil can come partly from the overflow valve 16 and partly from the channel 20. In the body 2 is. there are built-in heaters 27 which are supplied in a randomly suitable manner with a constant energy.
20 Når der.gennem kanalen.4 og tværkanalen 6 tilføres olie til apparatet, vil en del af denne olie passefe drøvleventilen 9, og en kontrolleret mængde,olie vil derfor passere gennem kanalen 10, kanalen 11, kanalen 13 og kanalen 14, hvorfra den løber ind i fordampningskammeret 15 og efter at have 25 passeret dette ud gennem kanalen 20 ned over bimetalfjederen 17 og ned i bunden af kassen 1, hvorfra den kan løbe ud gennem åbningen 26, når der er løbet så meget olie igennem, at kassen 1 er fyldt op til det dertil svarende niveau. Da‘ olien har en temperatur på omkring 50°C, og da den tempera-30 tur, hvorved man skal fordampe vand fra olien, ligger omkring 105-120°C og i det væsentlige tilvejebringes,ved hjælp af varmelegemerne 27, vil olien virke som et kølemiddel for legemet 2. Der tilvejebringes derfor en balance mellem kølingen og den konstante opvarmning, idet bimetalfjederen under 35 indvirkning af varmen fra legemet 2 og fra den olie, som 6 UU81 gennem kanalen 20 strømmer ned over bimetalfjederen, vil sørge for at regulere den oliemængde, der strømmer ud gennem overløbsventilen 16, qg dermed på tilsvarende måde regulere den oliemængde, der strømmer gennem fordampningskammeret.When, through channel 4 and cross channel 6, oil is supplied to the apparatus, a portion of this oil will pass through the throttle valve 9, and a controlled amount of oil will therefore pass through channel 10, channel 11, channel 13 and channel 14, from which it runs into the evaporation chamber 15 and after passing 25 through the passage 20 down the bimetal spring 17 and down to the bottom of the box 1, from which it can flow out through the opening 26 when so much oil has passed through that the box 1 is filled up to the corresponding level. Since the oil has a temperature of about 50 ° C and since the temperature at which to evaporate water from the oil is about 105-120 ° C and is essentially provided by the heaters 27, the oil will work. as a coolant for the body 2. Therefore, a balance is provided between the cooling and the constant heating, since the bimetal spring under the influence of the heat from the body 2 and from the oil which flows down the duct 20 through the channel 20 will provide for regulating the amount of oil flowing out through the overflow valve 16 qg accordingly regulates the amount of oil flowing through the evaporation chamber.
5 Dersom temperaturen af legemet 2 har tilbøjelighed fil at stige over den ønskede temperatur, vil bimetalfjederen 17 sørge for at lukke mere til for overløbsventilen 16, således at en større mængde af den kølende olie nu løber igennem fordampningskammeret, men da disse variationer er relativt 10 små, får de ingen indflydelse på den mængde vand, som fordampes fra olien, således at den dampmængde, der passerer ud gennem åbningen 21 og ind i kondensatorrørene 23, hele tiden vil give et tilstrækkeligt nøjagtigt mål for det relative indhold af vand i olien. Omvendt vil bimetalfjederen 15 lukke mere op for oyerløbsventilen 16, dersom temperaturen af legemet 2 har tilbøjelighed til at falde under den ønskede værdi, Den effektive styring af bimetalfjederen opnås dels ved en god kontakt med legemet 2 og dels derved, at den olie, som strømmer ud gennem kanalen 20, har opnået den temperatur, 20 som svarer til legemets temperatur, hvilken olie som beskrevet rammer den nederste del af bimetalfjederen. Selve registreringen af de udkomne vanddråber kan foregå på vilkårlig hensigtsmæssig måde, idet det er indlysende, at man blot ved at se på dråbernes hyppighed kan danne sig et indtryk af 25 det relative vandindhold i olien, og ved direkte måling af tidsintervallerne kan man naturligvis efter en foretagen kontrol fastlægge det procentvise indhold af vand f.eks. i en kurve, eller man kan benytte tidsintervallerne direkte til gennem et elektronisk apparatur at fremkalde et alarmsignal 30 eventuelt en automatisk igangsætning af centrifuger til fjernelse af vandet fra olien. Selve det apparatur, som skal anvendes hertil, udgør ikke nogen del af opfindelsen, idet dette kan udformes på vilkårlig hensigtsmæssig måde og i overensstemmelse med almindelig kendt teknik.If the temperature of the body 2 tends to rise above the desired temperature, the bimetal spring 17 will close more to the overflow valve 16 so that a greater amount of the cooling oil now runs through the evaporating chamber, but since these variations are relatively small, they do not affect the amount of water evaporated from the oil, so that the amount of steam passing out through the aperture 21 and into the condenser tubes 23 will always provide a sufficiently accurate measure of the relative content of water in the oil. Conversely, the bimetal spring 15 will open more to the inlet valve 16 if the temperature of the body 2 tends to fall below the desired value. The effective control of the bimetal spring is achieved partly by good contact with the body 2 and partly by the oil flowing out of the channel 20, has obtained the temperature 20 corresponding to the body temperature, which oil, as described, hits the lower part of the bimetal spring. The actual recording of the droplets of water can be done in any convenient way, since it is obvious that by looking at the frequency of the droplets one can form an impression of the relative water content of the oil, and by direct measurement of the time intervals one can of course after a control carried out determine the percentage content of water e.g. in a curve, or one can use the time intervals directly to elicit through an electronic apparatus an alarm signal 30, optionally, an automatic start of centrifuges to remove the water from the oil. The apparatus itself to be used for this purpose does not form part of the invention, since it can be designed in any suitable manner and in accordance with generally known techniques.
