Abstract

Ved ifølge frembringelsen at tillede fedt (3) fra en fedtbeho (1) til en strøm ningspumpe (6) opnås, at fedtet under tryk kan ledes til en eller flere stempel- pumper (12), hvorved der dels opnås et højt smøretryk, dels mulighed for anven delse af svær fedt, da pumpehjulet (5) vil ælte fedtet (3) til en pumpbar konsi stens. Apparatet, som er kompakt og let, lader sig let indbygge i en kuffert og dermed transportere, hvilket er en fordel, da det derved kan anvendes til f.eks. central- smøring af vinddrevne generatorer.By supplying grease (3) from a grease container (1) to a flow pump (6) according to the invention, the grease can be fed under pressure to one or more piston pumps (12), thereby obtaining a high lubrication pressure and partly possibility of using heavy grease as the impeller (5) will knead the grease (3) to a pumpable consistency. The apparatus, which is compact and light, can easily be incorporated into a suitcase and thus transport, which is an advantage as it can thereby be used for e.g. central lubrication of wind-driven generators.

FEDTSMØREAPPARATFAT LUBRICATOR

Den kendte teknikThe prior art

Frembringelsen angår et fedtsmøreapparat til brug ved fedtsmøring af et eller flere smøresteder, og omfattende en fedtbeholder og en eller flere fedtpumper, fortrinsvis i form af stempelpumper, til udpumpning af fedt via tilsluttede forbindelsesrør eller -slanger.The invention relates to a grease lubricant for use in greasing one or more lubrication sites, and comprising a grease container and one or more grease pumps, preferably in the form of piston pumps, for pumping grease out via connected connecting pipes or hoses.

Apparater af denne art kendes i form af centralsmøreapparater, som omfatter en fedtbeholder med fedt, som står i forbindelse med en smørepumpes tilgangsside, og hvor afgangssiden eventuelt via en slangeforbindelse er forbundet med et smøre reservo ir eller direkte med smørestedet.Apparatus of this kind is known in the form of central lubricators, which comprise a grease container with grease which is connected to the supply side of a lubrication pump and the outlet side is possibly connected via a hose connection to a lubricant reservoir or directly to the lubrication site.

Pumperne er sædvanligvis strømningspumper, som drives afen elektrisk motor.The pumps are usually flow pumps driven by an electric motor.

Disse apparater benyttes både til olie- og fedtsmøring. Da fedtsmøring er den mest hensigtsmæssige ved større anlæg, såsom vinddrevne generatorer, må fedtet have en relativ tynd konsistens for, at pumpen kan påtrykke fedtet til smørestedet på sikker måde.These appliances are used for both oil and grease lubrication. Since grease lubrication is most appropriate for larger systems, such as wind-driven generators, the grease must have a relatively thin consistency for the pump to safely apply grease to the lubrication site.

Da der herved opnås en mindre effektiv smøring med fedt under tryk, må der smøres med kortere intervaller, hvilket er forbundet med betydelige omkostninger.As this results in less efficient grease under pressure, grease must be lubricated at shorter intervals, which is associated with considerable costs.

Formålet med frembringelsenPurpose of production

Det er formålet med frembringelsen at afhjælpe disse mangler ved smøreapparater af denne art, og dette opnås ifølge frembringelsen ved et apparat, hvor der er monteret en fedtpumpe i form af en roterende strømningsfedtpumpe mellem fedtbeholderen og fedtpumpen/fedtpumperne.The object of the present invention is to remedy these deficiencies by lubricators of this kind, and this is achieved according to the present invention by an apparatus in which a grease pump in the form of a rotary flow grease pump is mounted between the grease container and the grease pump (s).

2 DK 2009 00197 U3 På denne overraskende enkle måde sikrer man et fédttryk, som er tilstrækkeligt højt til, at der kan opnås smøring af op til flere smøresteder, ligesom der er mulighed for anvendelse af tykkere eller fastere fedt.2 DK 2009 00197 U3 This surprisingly simple way ensures a fat pressure that is sufficiently high to allow lubrication of up to several lubrication points, as well as the possibility of using thicker or firmer grease.

Dette skyldes den yderligere strømningsfedtpumpe, idet pumpehjulet under rotation vil ælte fedtet, således at dette bliver blødere og dermed lettere lader sig pumpe ud til de efterfølgende pumpecylindre.This is due to the additional flow grease pump, since the impeller will rotate the grease during rotation so that it becomes softer and thus easier to pump out to the subsequent pump cylinders.

Herved kan apparatet pumpe svær fedt og således sikre en hensigtsmæssig smøring med passende intervaller. Dette medfører store besparelser og vedligeholdelse af anlæg med centralsmøringThis allows the apparatus to pump heavy grease and thus ensure an appropriate lubrication at appropriate intervals. This results in major savings and maintenance of systems with central lubrication

Ved, som omhandlet i krav 2 og 3, at opbygge apparatet omkring en roterbar aksel med en drivskive til bevægelse af stempelpumperne og pumpehjulet opnås en kompakt og driftsikker konstruktion.As defined in claims 2 and 3, the apparatus is built around a rotatable shaft with a drive disc for moving the piston pumps and the impeller, a compact and reliable construction is achieved.

Ved, som omhandlet i krav 4, at anvende en drivskive med en skråt forløbende overside vil et stort antal stempelpumper kunne monteres, og dermed tilføres et tilsvarende antal rørledninger fedt.By using a drive disc with a sloping upper surface, as claimed in claim 4, a large number of piston pumps can be mounted, and thus a corresponding number of pipelines are greased.

Ved, som omhandlet krav 5, at udføre kanalerne mellem strømningsfedtpumperne i centrum og kanalerne radialt forløbende herfra opnås, at hver af stempelpumperne opnår en ensartet tilledning af fedt og dermed fedttilledning til de enkelte smøresteder, som tilsluttes.As claimed in claim 5, conducting the channels between the flow grease pumps in the center and the channels radially extending from here, it is achieved that each of the piston pumps achieves a uniform supply of grease and thus grease supply to the individual lubrication points which are connected.

TegningenThe drawing

Et eksempel på en udførelsesform for anlægget ifølge frembringelsen vil i det følgende blive nærmere beskrevet under henvisning til tegningen, som viser et 3 DK 2009 00197 U3 delvist snitbillede af anlægget set fra siden.An example of an embodiment of the plant according to the invention will be described in more detail below with reference to the drawing, which shows a side sectional view of the plant.

Beskrivelse af et udførelseseksempel På tegningen er vist de i apparatets fedtsmøreudstyr indgående dele. Delene er i praksis udformet som en kompakt enhed, der drives ved hjælp af en ikke-vist strømenhed, såsom et batteri eller en akkumulator. Dette udstyr kan indbygges i en kuffert, som let lader sig transportere til smørestedet.Description of an embodiment The drawings show the parts included in the grease lubrication equipment of the apparatus. In practice, the parts are designed as a compact unit powered by a non-shown power unit, such as a battery or accumulator. This equipment can be built into a suitcase that is easily transportable to the lubrication site.

Fedtet opbevares i en beholder, der som vist på tegningen er udformet fleksibelt ved hjælp af ringformede plisseringer, således at når fedtet 3 i beholderen 1 udsuges forneden, vil beholderen "følge med” fedtet og dermed sikre, at der ikke opstår vakuum i beholderen.The grease is stored in a container which, as shown in the drawing, is flexibly formed by annular pleats so that when the grease 3 in the container 1 is extracted below, the container will "follow" the grease and thus ensure that no vacuum is created in the container.

Fedtbeholderen er skruet på et optagestykke 4, som udgør en del af en montageflange 21. En boring sikrer fedttilledningen til sugesiden af et pumpehjul 5 i en strømningspumpe 6. Hjulet 5 drives af en aksel 11, som forneden er forsynet med et drivhjul 10, som via en rem eller kæde 9 roteres af en elektromotor 8.The grease container is screwed onto a take-up piece 4, which forms part of a mounting flange 21. A bore secures the grease supply to the suction side of a pump wheel 5 in a flow pump 6. The wheel 5 is driven by a shaft 11, which is provided with a drive wheel 10, which via a belt or chain 9 is rotated by an electric motor 8.

Herudover er der monteret stempelpumper 12, der som vist er monteret omkring strømningspumpen 6, hvilke stempelpumper kan være en eller flere.In addition, there are mounted piston pumps 12 which, as shown, are mounted around the flow pump 6, which piston pumps can be one or more.

Hvis behovet er stort, må den radiale afstand fra strømningspumpen øges. I praksis vil der fortrinsvis være monteret op til otte stempelpumper 12 i flangen 21.If the need is high, the radial distance from the flow pump must be increased. In practice, up to eight piston pumps 12 will preferably be mounted in the flange 21.

Der forløber en fedtkanal 18 fra strømningspumpens afgangsside ud til indløbssiden af hver stempelpumpe 12.A grease channel 18 extends from the discharge side of the flow pump to the inlet side of each piston pump 12.

Stempelpumperne 12 er opbygget med en cylinder 13, hvortil kanalen 18 er tilsluttet. I cylinderen forløberet stempel 14 med en stempelstang 15, som presses nedad ved hjælp afen trykfjeder 16.The piston pumps 12 are constructed with a cylinder 13 to which the duct 18 is connected. In the cylinder, piston 14 is provided with a piston rod 15 which is pressed down by a compression spring 16.

Stempelstængerne 15 hviler mod en drivskives 7 overside 17, hvilken skive er fastgjort til akslen 11.The piston rods 15 rest against the upper side 17 of a drive disc 7, which disc is attached to the shaft 11.

Oversiden 17 af skiven 7 er skråt forløbende for under skivens rotation at påvirke de forskellige stempelstænger 15 til at udføre en reoiprocerende bevægelse og dermed en udpumpning affedtet i cylindrene.The upper surface 17 of the disc 7 is inclined to act during the rotation of the disc to influence the various piston rods 15 to perform a reprocessing movement and thus a pumping out of grease in the cylinders.

Under skivens 7 rotation bevæges stemplerne 14 og udpumper fedtet under den opadgående stempelbevægelse, medens en kontraventil 19 sikrer fedtet mod at blive tilbagesuget under stemplets bevægelse nedefter.During rotation of the disc 7, the pistons 14 move and pump out the fat during the upward piston movement, while a check valve 19 protects the fat from being sucked back downwards during the piston movement.

Udpumpningen, som er antydet ved pile, sker via nipler 20, hvortil der er skruet ikke-viste slanger eller rør. Hvor der ikke er behov for udpumpning fra en eller flere af stempelpumperne 12, kan den eller de udledninger blokeres af ikke-viste afdækninger.The pumping, indicated by arrows, takes place via nipples 20 to which are not shown hoses or tubes. Where there is no need for pumping out of one or more of the piston pumps 12, the discharge (s) may be blocked by uncovered covers.

Funktionen af apparatet vil herefter blive beskrevet.The operation of the apparatus will then be described.

De ønskede smøresteder forbindes med niplerne 20 til apparatet ved hjælp af slanger eller rør. Herefter påskrues en fedtbeholder 1.The desired lubrication points are connected to the nipples 20 to the apparatus by means of hoses or tubes. Then tighten a grease container 1.

Når der skal smøres, startes motoren 8, og drivakslen 11 samt pumpehjulet 5 bringes til rotation.When lubricating, the motor 8 is started and the drive shaft 11 and the impeller 5 are rotated.

Pumpehjulet 5 suger fedtet 3 ud fra beholderen 1, og fedtet vil under rotationen blive æltet, således at selv svær fedt vil blive pumpbart.The impeller 5 sucks the grease 3 out of the container 1 and the grease will be kneaded during rotation so that even heavy grease will be pumpable.

Fedtet trykkes herefter via kanaler 18 ind i de forskellige strømningspumper, som vil pumpe det videre ud til smørestederne via kontraventilerne 19 og niplerne 20.The grease is then pressed through channels 18 into the various flow pumps which will pump it out to the lubrication points via the check valves 19 and the nipples 20.

Der vil på denne måde opnås et kraftigt smøretryk, idet strømningspumpen vil foretrykke fedtet ind i stempelpumperne og derved sikre en effektiv udpumpning med et højt smøretryk.In this way, a strong lubrication pressure will be obtained, since the flow pump will prefer the grease into the piston pumps, thereby ensuring an efficient pumping with a high lubrication pressure.

Da der tillige kan anvendes svær fedt, vil der kunne smøres på den mest hensigtsmæssige måde med det bedst egnede fedt.Since heavy fat can also be used, it will be possible to lubricate in the most appropriate manner with the most suitable fat.

Da der ingen lufttilledning finder sted til fedtet, vil det forblive rent og usmittet i apparatet.As there is no air supply to the grease, it will remain clean and uninfected in the appliance.
