Description

Uppfinnare: L Hornbostel Foreliggande uppfinning hanfor sig till en anordning for synlig kontroll av vatskegenomstromningen i en rOrledning, sfirskilt en smorjoljeledning. Harvid fir det kant att i forledningen inkoppla en synglasindikator Hied sluten betraktningskammare och att genom en anordning infora en gas, exempelvis luft, i denna kammare. Inventor: L Hornbostel The present invention relates to a device for visible control of the liquid flow in a pipeline, in particular a lubricating oil pipeline. In this case, it is possible to connect a sight glass indicator in the lead to a closed viewing chamber and to introduce a gas, for example air, into this chamber through a device.

Hittills liar smorjningen av pappersmaskiner och liknande omangsrika och invecklade maskinella utrustningar varit besvfirlig att reglera och overvaka genom inspektion eller visuell observation. Salunda liar det varit nodvfindigt att placera med sjfilvtryck matade lubrikatorer, fOrsedda med synglas, pa storsta mojliga hOjd, varjamte komplicerade rOrsystem erfordrats. Dessutom fir det vid sadana smorjsystem nodvandigt, att maskinskotaren med täta mellanrum klattrar uppfor en hog trappa for att inspektera synglasen. Until now, the lubrication of paper machines and similar bulky and complex mechanical equipment has been difficult to regulate and monitor through inspection or visual observation. Therefore, it has been necessary to place self-pressure-fed lubricators, equipped with sight glass, at the greatest possible height, and complicated pipe systems are required. In addition, in such lubrication systems, it is necessary for the machine forwarder to climb up a high staircase at frequent intervals to inspect the sight glasses.

Tryckmatade lubrikatorer, forsedda med synglas, aro & andra sidan icke tinforlitliga under langre driftperioder och Ni latt igensatta eller ge felaktiga indikationer betraffande genomstromningen. Vid pappersmaskiner och liknande maskinerier fir det emellertid Midvandigt, att smorjningsanordningarna aro fullt tillforlitliga. Pressure-fed lubricators, equipped with sight glasses, aro & on the other hand are not tin-reliable for longer operating periods and you have left clogged or give incorrect indications regarding the flow. In the case of paper machines and similar machinery, however, it is Midvandigt that the lubrication devices are fully reliable.

Det är kAnt att anordna smorjmedelsbehh.1- lare, i vars botten finnes en nalventil for att reglera utstromningen av smorjmedel till en nedre kammare f6rsedd med en transparent cylinder for att tillâta visuell observation av smorjmedelsstrommen Iran en munstycksoppning. For att denna cylinder skall hallas fri frau bubblor eller liknande, som ofta upptrada vid anvandning av tvalhaltiga smorjmedel, finnes en utjamningsledning, vilken mynnar i cylinderns ovre del och star i forbindelse med en rorledning, vars ovre ande är anbragt i smorjmedelsbehallarens ovre del ovanfor den hogsta smorjmedelnivan. Cylinderns utlopp star i forbindelse med en insug- ningsledning, till vilken aven behallarens ovre del ar ansluten. Forbindelseledningarna ha till uppgift att utjamna gastrycket mellan behMlaren och cylindern. Med undantag for det statiska tryck som utovas p smorjmedlet pa grund av vitskepelaren i behfillaren kan nagon tryckskillnad joke uppsta. Om gastrycket I insugningsledningen stiger Over gasens tryck i belallaren, kommer gas att stromma till behallarens Ovre del frau insugningsledningen, men man erhaller ingen renblasning av den som betraktningskammare avsedda cylindern, vilket är av storsta betydelse for anordning_ ens driftsakerhet. It is possible to provide lubricant containers, in the bottom of which there is a needle valve to regulate the outflow of lubricant to a lower chamber provided with a transparent cylinder to allow visual observation of the lubricant stream Iran a nozzle opening. In order to keep this cylinder free from bubbles or the like, which often occur when using desalinated lubricants, there is a leveling line, which opens into the upper part of the cylinder and stands in connection with a pipe, the upper spirit of which is arranged in the upper part of the lubricant container above the hogsta lubricant level. The outlet of the cylinder is connected to an intake line, to which also the upper part of the container is connected. The task of the connecting lines is to equalize the gas pressure between the tank and the cylinder. With the exception of the static pressure exerted on the lubricant due to the white column in the container, any pressure difference joke can occur. If the gas pressure in the suction line rises.

Till skillnad frail vad fillet är vid den kfinda anordningen avser foreliggande uppfinning att astadkomma tvfingsmassig renblAsning av betraktningskammaren under anvandande av en gaskalla med overtryck. Enligt uppfinningen innetattar den for inforande av gas eller luft i betraktningskammaren avsedda anordningen en till en gaskalla anslutbar rorledning, som mynnar i den slutna betraktningskammaren och innehaller en ventil, varvid gaskallans tryck är sa avpassat, att gastrycket i den slutna betraktningskammaren vid oppen ventil är sa hOgt att betraktningskammaren tvangsvis renblases frail vatska. In contrast to the fillet in the present device, the present invention seeks to provide for forced purification of the viewing chamber using an overpressure gas skull. According to the invention, the device for introducing gas or air into the viewing chamber occupies a pipeline connectable to a gas shell, which opens into the closed viewing chamber and contains a valve, the gas skull pressure being so adapted that the gas pressure in the closed viewing chamber at open valve is so high that the viewing chamber is forcibly purified frail liquid.

Uppfinningen beskrives narmare i det foljande i anslutning till bifogade ritning, pa vilken fig. 1 schematiskt visar en med luftmanovrerade synglas forsedd centralsmorjanordning for en pappersmaskin, medan fig. 2 i stone skala och sett framifran visar ett synglas jamte en anordning for luftmanovrering av delta. Fig. 3 visar schematiskt en med lullmanovrerade synglas enligt en annan utf0- ringsform av uppfinningen forsedd centralsmorjanordning och fig. 4 visar schematiskt en annan utforingsform av uppfinningen, vid vilken olja under tryck tillfores ett synglas av den i fig. 2 visade typen. The invention is described in more detail in the following in connection with the accompanying drawing, in which Fig. 1 schematically shows a central lubricating device provided with air-operated sight glass for a paper machine, while Fig. 2 shows on a stone scale and seen from the front a sight glass and a device for air maneuvering delta. Fig. 3 schematically shows a central lubricating device provided with wool-maneuvered sight glass according to another embodiment of the invention, and Fig. 4 schematically shows another embodiment of the invention, in which oil is supplied under pressure with a sight glass of the type shown in Fig. 2.

Pa ritningen visas i fig. 2 ett synglas 10 en- 2- - ligt uppfinningen av vanlig dropp- eller sjalvtryckstyp och innefattande en dosa 12, som kan best a av gjutjarn eller dylikt med ett genomsynligt Ranter 14, sa att detta tillsammans med dosan 12 avgransar en sá nar som pa in- och utloppsoppningar sluten kammare 16. Olja eller annan vatska infores under tryck i denna kammare 16 genom ett ror 17, som är anslutet till en inloppskanal 18. TillfOrseln av dylik vatska till kammaren regleras med hjalp av en strypventil med ett manoverhandtag 20 och en ventilkropp 22, och inloppsvatskan strommar genom en kanal 24, som mynnar i ett i kammaren 16 beldget munstycke 26. Munstycket 26 är belaget pa givet avstand fran kammarens 16 botten, och oljan slappes ut ur dosan 12 genom en utloppskanal 28, som star i forbindelse med ett r8r 30, vilket leder till det eller de avsedda smorjstallena i maskineriet, sasom utan vidare ins es . The drawing shows in Fig. 2 a sight glass 10 according to the invention of the usual drip or self-pressure type and comprising a box 12, which may consist of cast iron or the like with a transparent Ranter 14, so that this together with the box 12 delimits a chamber 16 which is closed in inlet and outlet openings. Oil or other liquid is introduced under pressure into this chamber 16 through a pipe 17, which is connected to an inlet duct 18. The supply of such liquid to the chamber is regulated by means of a throttle valve. with a control handle 20 and a valve body 22, and the inlet water flows through a channel 24, which opens into a nozzle 26 belded in the chamber 16. The nozzle 26 is coated at a given distance from the bottom of the chamber 16, and the oil is discharged from the can 12 through an outlet channel 28, which is connected to a pipe 30, which leads to the intended lubrication stall (s) in the machinery, as is readily apparent.

I enlighet med en utforingsform av uppfinningen finnes en anordning for tomning av kammaren 16, bestaende av ett pneumatiskt system med tillforselledning 32, som star i forbindelse med ett gas-, exempelvis luftforrad, som kan albs under tryck med hjalp av en lamplig (icke visad) kompressor eller liknande. Tilloppsledningen 32 är ansluten till dosan 12 medelst en sa anbragt stuts eller nippel 34, att gasstrommen frail ledningen 32 genom en inloppskanal 36- instrommar i kammarens 16 ovre del. In accordance with an embodiment of the invention there is provided a device for emptying the chamber 16, consisting of a pneumatic system with supply line 32, which is connected to a gas, for example air supply, which can be pressurized by means of a lamp (not shown). ) compressor or the like. The supply line 32 is connected to the box 12 by means of a socket or nipple 34 arranged in such a way that the gas stream from the line 32 flows into the upper part of the chamber 16 through an inlet channel 36.

Tillforsel av luft eller annan gas kan startas och avbrytas med hjalp av en tryckknappsventil 38, som ar placerad pa godtyckligt lampligt stalle ldngs ledningen 32, foretradesvis i narheten av synglasdosan 12, ddr den ar latt atkomlig av den som overvakar sm8rjanordningen. Tryckknappsvenkilen 38 kan vara av godtyckligt lamplig typ och her foretradesvis en tryckknapp 40, scan dr anIragt pa ett skaft 42 och medelst en lamplig (icke visad) fjacleranordning fir rorlig till ett overksamt, stangt 'age, I vilket gasen av en lamplig (icke visad) ventilkropp hindras fran att strOmma genom ventilhuset 44. Supply of air or other gas can be started and interrupted by means of a push-button valve 38, which is located in any suitable position along the line 32, preferably near the sight glass box 12, where it is easily accessible by the person monitoring the lubrication device. The push-button wrench 38 may be of any lamp type, and preferably a push-button 40, scanned thereon on a shaft 42 and by means of a lamp (not shown) fixture movable to an inactive, rod ', in which the gas of a lamp (not shown) ) valve body is prevented from flowing through the valve housing 44.

Under smorjanordningens arbete strommar olja genom inloppet 18 in. i kammaren 16 och stravar att fylla denna till foljd av det i anordningen radande stromningsmotstandet. Da man onskar inspektera aljeflodet genom anordningen eller utrona, cm nagon del av denna Ar tilltappt, tryckes ventilknappen 40 in, sa. att tilloppsledningen 32 Oppnas och tryckluft slappes in i kammaren 16, varvid lufttrycket Ar sa avpassat, att det natt och jamnt overvinner det i smarjanordningen radande motstandet mot oljans genomstromning. pa sa satt tOmmes eller renblases kammaren 16 fOr inspektion, genom att olj an i nedre delen :av denna kammare tryckes in i OverforingsAedningen 30 till ifragavarande smorjstalle. 2iven om sjalva lufttrycket tilifAlligIvis kan utnyttjas fAr att astadkomma smorjning, ar oljetrycket i smorjanordningen lampligen sA avpassat, att det sakerstaller kontinuerlig smorjoljetillforsel. Om flagon del av ifragavarande ledningssystem skulle vara tilltappt, kan kammaren 16 icke genomblasas, dd. ventilknappen 40 tryckes in, och darigenom far den inspekterande vetskap om detta fOrhallande. During the operation of the lubrication device, oil flows in through the inlet 18. in the chamber 16 and strains to fill it as a result of the flow resistance radiating in the device. When one wishes to inspect the oil flow through the device or to find out if any part of it has been drained, the valve button 40 is pressed in, said. that the supply line 32 is opened and compressed air is let into the chamber 16, whereby the air pressure Ar is so adapted that it night and even overcomes the resistance in the lubrication device to the flow of the oil. in this way the chamber 16 is emptied or cleaned for inspection, by applying oil in the lower part: of this chamber is pressed into the transfer line 30 to the lubrication stable in question. Although the air pressure itself can possibly be used to effect lubrication, the oil pressure in the lubricating device is suitably adjusted so that there is a continuous supply of lubricating oil. If the flake part of the conduit system in question should be clogged, the chamber 16 cannot be blown through, dd. the valve button 40 is pressed in, thereby giving the inspecting knowledge of this condition.

I enlighet med uppfinningen kan, sasom visas i fig. 1, en centralsmorjanordning anvandas, vid vilken ett flertal smorjoljeledningar 46, 48, 50, 52 och 54 Arc avgrenade fran en till ett oljeforrad eller en matarpump ansluten matarledning 55 och leda till olika lager 56, 58, 60, 62 resp. 64 for pappersvalsar eller andra i en pappersmaskin ingaende organ, som visas schematiskt vid 63, 65, 67, 69 resp. 70. Oljeledningarna 46-54 aro forsedda med var sitt synglas 72, 74, 76, 78 resp. 80, vilka kunna manovreras medelst ett tryckluftsystem, innehallande en trycklultskalla 82, som genom en fordelare 84 mater tryckluft till ett antal grenledningar 86, 88, 90, 92 och 94, anslutna till var sin av synglasindikatorerna 72-80. Lufttillforselanardningen arbetar i huvudsak pa samma salt som beskrivits i det foregaende och manovreras med hj Alp av en sfirskild ventil 96, 98, 100, 102 resp. 104 for var och en av grenledningarna 86-94, varvid derma ventil kan vara av den i fig. 2 visade tryckknappstyp en. In accordance with the invention, as shown in Fig. 1, a central lubricating device may be used in which a plurality of lubricating oil lines 46, 48, 50, 52 and 54 Arc branch from a supply line 55 connected to an oil supply or a feed pump and lead to different bearings 56 , 58, 60, 62 resp. 64 for paper rolls or other means incorporating in a paper machine, shown schematically at 63, 65, 67, 69 resp. 70. The oil lines 46-54 are each provided with a sight glass 72, 74, 76, 78 resp. 80, which can be maneuvered by means of a compressed air system, containing a compressed air head 82, which through a distributor 84 supplies compressed air to a number of branch lines 86, 88, 90, 92 and 94, connected to each of the sight glass indicators 72-80. The air supply device operates essentially on the same salt as described above and is operated by means of a separate valve 96, 98, 100, 102 and 102, respectively. 104 for each of the manifolds 86-94, this valve being of the pushbutton type shown in FIG.

Enligt en sarskilt lAmplig utforingsform av uppfinningen kan man ocksa anvanda en enda ventil for att starta och avbryta lufttillforseln till samtliga i centralsmorjanordningen ingdende synglasinclikatorer, sasom visas i fig. 3, dar samma hanvisningsbeteckningar anvandas som i fig. 1 fOr motsvarande tryckluftledningar, dock med tillagg av bokstaven a. Salunda ar utloppsledningen 84a fran tryckluftskallan 82 forsedd med en ventil 96, som ocksa kan vara av den i fig. 2 visade tryckknappstypen och vid oppnandet blAser igenom alla synglasindikatorerna 72-80 samtidigt, sa att den overvakande besparas besvaret att manovrera en sarskild ventil for var och en av indikatorerna och darjamte far rajlighet att jamfora oljeflodena genom lufttillloppsledningarna eller grenledningarna 86a-94a. According to a particularly suitable embodiment of the invention, it is also possible to use a single valve to start and interrupt the air supply to all sight glass incliners contained in the central lubrication device, as shown in Fig. 3, where the same reference numerals are used as in Fig. 1 for corresponding compressed air lines. Thus, the outlet line 84a from the compressed air head 82 is provided with a valve 96, which may also be of the push button type shown in Fig. 2 and upon opening blows through all the sight glass indicators 72-80 simultaneously, so that the supervisor is spared the task of maneuvering a separate valve for each of the indicators and in addition it is possible to compare the oil flows through the air supply lines or branch lines 86a-94a.

I fig. 4 visas ytterligare en utfaringsform av uppfinningen, vid vilken luftmanovreringen ytterligare forenklats genom. att olja under tryck tillfores en synglasindikator 100, som stort sett ar av den for dropp- eller sjalvtrycksmatning avsedda konstruktion, som visas i fig. 2. Oljan tillfores. indikatorn 100 genom en ledning 102, till vilken Ar ansluten en. luftfylld utjamningskammare 104 fare ledningens anslutning till indikatorn 100. Oljan overfores genom en utloppsledning 106 frail indikatorn till ett eller flera smorjstallen, och till foljd av det tryckf all, som sker da aljan — —3 strommar in i indikatorn, kommer den frail utjamningskammaren 104 medsugna luften att frigoras fran oljan inuti indikatorn och darvid effektivt rensa synglaset och synglaskammarens vaggar, sâ att strOmningstillstandet i smorjsystemet tydligt kan observeras, sasom beskrivits i det foregaende. Luft kan frigoras ur oljan aven utan nagon luftfylld utjamningskammare fore indikatorn, namligen till Mild av tryckskillnaden mellan tryckoljeledningens 102 inre och kammaren i indikatorn 100. Fig. 4 shows a further embodiment of the invention, in which the air maneuvering is further simplified by. that oil under pressure is supplied to a sight glass indicator 100, which is substantially of the structure intended for drip or self-pressure supply, as shown in Fig. 2. The oil is supplied. the indicator 100 through a line 102, to which Ar is connected a. air-filled equalization chamber 104 will connect the line to the indicator 100. The oil is transferred through an outlet line 106 from the indicator to one or more lubrication stalls, and as a result of the pressure which occurs when the oil flows into the indicator, the frail equalization chamber 104 will be aspirated. the air to be released from the oil inside the indicator, thereby effectively cleaning the sight glass and the cradle chamber cradles, so that the flow condition of the lubrication system can be clearly observed, as described above. Air can be released from the oil even without an air-filled equalization chamber in front of the indicator, namely to Mild by the pressure difference between the interior of the pressure oil line 102 and the chamber in the indicator 100.

I detta samband är att marka, att aven om en liten mangd luft (eller annan gas) kan bortga genom oljeoverforingsledningarna fran de skilda synglasindikatorerna i de beskrivna utfOringsformerna av uppfinningen, kan denna mangd begransas till ett absolut minimum, genom att man endast behover tillfora indikatorn en mycket ringa luftmangcl under mycket kort tid for att overvinna det i indikatorkammaren radande trycket och rengora synglaset. Om en sâ liten luftmangd verkligen bortgar pa detta satt, medfor detta farst en viss tryckminskning i indikatorkammaren, oeh darefter stiger oljenivan i denna, emedan det pa oljan i kammarens nedre del verkande lufttrycket salunda har minskat. Detta innebar alltsa, att oljan i kammarens utlopp forhindrar ytterligare utstromning av luft genom detta utlopp. In this connection, it should be noted that although a small amount of air (or other gas) can pass through the oil transfer lines from the various sight glass indicators in the described embodiments of the invention, this amount can be limited to an absolute minimum, by only needing to supply the indicator. a very small air gap for a very short time to overcome the pressure radiating in the indicator chamber and clean the sight glass. If such a small amount of air really disappears in this way, this leads to a certain reduction in pressure in the indicator chamber, and then the oil level in it rises, because the air pressure acting on the oil in the lower part of the chamber has thus decreased. This means that the oil in the outlet of the chamber prevents further outflow of air through this outlet.

Man her salunda erhallit en med synglas forsedd smiirjanordning for pappersmaskiner och liknande, vid vilken man undviker tendensen till igentappning eller stockning i trycksmorjanordningar och kan erhalla ett for obehindrad visuell inspektion lampligt tillstand hos synglasen, narhelst man sa Onskar. Anordningen är synnerligen enkel och oom och är darfor billig saval i tillverkning sum i underhall samt kan betjanas pa tidsbesparande satt. They have thus obtained a sight glass-equipped lubricating device for paper machines and the like, in which the tendency to clogging or clogging in pressure-lubricating devices is avoided and a condition suitable for unobstructed visual inspection of the sight glasses can be obtained, whenever it is desired. The device is extremely simple and unobtrusive and is therefore inexpensive to manufacture in maintenance and can be operated in a time-saving manner.

Aven om anordningen är sarskilt lamplig i samband med smorjanordningar for pap- persmaskiner, kan den anvandas ocksa i talrika andra fall, dar det är onskvart att forenkla konstruktionen av lednings- och Overvakningsanordningarna for smorjanordningar. Although the device is particularly suitable in connection with lubrication devices for paper machines, it can also be used in numerous other cases, where it is undesirable to simplify the construction of the control and monitoring devices for lubrication devices.

Uppfinningen ãr givetvis joke begransad till de liar beskrivna utforingsformerna, at an kan varieras pa manga andra salt irtom ramen for patentanspraken. The invention is of course joke limited to the embodiments described above, that it can be varied on many other salts within the scope of the patent claims.
