Description
Som bekjent er sidekanalpumper på grunn av den trange spalte mellom løpehj.ul og pumpehus-noe ømfintlige overfor fremmedlegemer, så særlig mindre pumper kan bli tilsmusset og dermed blokkert. Det er altså ønskelig å-gjøre pumperommet tilgjengelig for rensning og eventuelt også for utskiftning av løpehjul og pakning, og det uten' noe spesielt verktøy. Der finnes: forskjellige løsningsmuligheter for å- feste pumpedeks elet; i huset på en slik måte -at det blir forholdsvis enkelt å:, fjerne,; f. eks. ved hjelp av fastspenningselementer eller lignende. Slike holdeélementer må dog utføres så stabile at de under hensyntagen til-det indre.pumpetrykk holder dekselet fastspent på en motsvarende tetningsflate. Dette betinger, igjen nøyaktig bearbeidede anleggs-; og. innspenningsflater, noe som betyr et tillegg i omkost-ninger. As you know, side channel pumps are somewhat sensitive to foreign bodies due to the narrow gap between the impeller and pump housing, so smaller pumps in particular can become dirty and thus blocked. It is therefore desirable to make the pump room available for cleaning and possibly also for replacing the impeller and gasket, and that without any special tools. There are: different solutions for attaching the pump cover; in the house in such a way -that it becomes relatively easy to:, remove,; e.g. by means of clamping elements or the like. However, such holding elements must be made so stable that, taking into account the internal pump pressure, they keep the cover clamped onto a corresponding sealing surface. This conditions, again precisely machined plant-; and. clamping surfaces, which means additional costs.
For oppfinnelsen er der stillet den oppgave å gjøre denne på-kostning overflødig. Man går her ut fra en sidekanalpumpe som har et indre deksel som lukker for pumpens arbeidsrom, og et ytre deksel som er festet til kapselen, samtidig som det indre deksel ligger an mot arbeidsrommets hus under trykket av minst ett fjærelement anordnet mellom de to deksler. Ifølge oppfinnelsen er ytterdekselet festet på pumpekapselen ved hjelp av to U-formede holdeelementer, hvis ene ben griper inn i en uttagning i kapselen, mens det annet ben griper omkring dekslet og er forsynt med fliker som er bøyet i vinkel innover og griper bak fjærende, knaster i dekselet. Denne utformning gjør det mulig på enkel måte å lukke pumpen uten verktøy. Videre får en mindre nøy-aktig stilling av det ytre. deksel ingen innflytelse på pumpens arbeidsrom. Det blir derved mulig å overspenne større toleranser ved det ytre pumpedeksel og også ved dets holdeelement. For the invention, the task is to make this expense redundant. The starting point here is a side channel pump that has an inner cover that closes off the pump's working space, and an outer cover that is attached to the capsule, while the inner cover rests against the housing of the working space under the pressure of at least one spring element arranged between the two covers. According to the invention, the outer cover is attached to the pump capsule by means of two U-shaped holding elements, one leg of which engages in a recess in the capsule, while the other leg engages around the cover and is provided with tabs that are bent at an angle inwards and engage behind springy, knobs in the cover. This design makes it possible to easily close the pump without tools. Furthermore, the exterior gets a less precise position. cover no influence on the pump's working space. It is thereby possible to exceed larger tolerances at the outer pump cover and also at its holding element.
Sidekanalpumpen ifølge oppfinnelsen er anskueliggjort ved et utførelseseksempel på tegningen. The side channel pump according to the invention is illustrated by an embodiment in the drawing.
Fig. 1 viser tverrsnitt av pumpen. Fig. 1 shows a cross section of the pump.
Fig. 2 er et perspektivriss av pumpen, og Fig. 2 is a perspective view of the pump, and
fig. 3 er et perspektivriss av et holdeelement for pumpedeks elet. 1 betegner pumpehuset, hvori der sitter et midtstykke 3 som inneholder sidekanalen 2. På den ytre omkrets av stykket 3 er der presset en ring 4 som et indre deksel 5 har tettende anlegg imot. Disse deler 3, 4 og 5 omgir pumpens arbeidsrom hvor løpehjulet 6 roterer. 7 betegner et ytre pumpedeksel som er festet til huset 1. Mellom dette ytre deksel 7 og det indre deksel 5 er der anbragt en fjær 8 som trykker det indre deksel 5 tettende mot ringen 4. Mellom huset 1 og ytterdekselet 7 er der anbragt en radialt tettende pakriingsring 9« Mellomrommet 10 mellom ytterdeksel 7 og innerdeksel "5 står i forbindelse med pumpens trykkrom 11, så 'trykkraften av innerdekselet 5 mot ringen 4 tiltar med Økende trykkutvikling og der dermed alltid vil foreligge en tilstrekkelig tetning mellom disse to deler. fig. 3 is a perspective view of a holding element for the pump cover. 1 denotes the pump housing, in which there is a central piece 3 which contains the side channel 2. On the outer circumference of the piece 3 is pressed a ring 4 against which an inner cover 5 has a sealing contact. These parts 3, 4 and 5 surround the pump's working space where the impeller 6 rotates. 7 denotes an outer pump cover which is attached to the housing 1. Between this outer cover 7 and the inner cover 5, a spring 8 is placed which presses the inner cover 5 sealingly against the ring 4. Between the housing 1 and the outer cover 7, there is placed a radial sealing packing ring 9" The space 10 between outer cover 7 and inner cover "5 is in connection with the pump's pressure chamber 11, so the pressure force of the inner cover 5 against the ring 4 increases with increasing pressure development and there will thus always be a sufficient seal between these two parts.
Befestigelsen av ytterdekselet 7 på huset 1 skjer ved hjelp av to holdeelementer 12 med U-formet tverrsnitt. Den ene flens av dette holdeelement griper inn i et spor 13 i huset, mens den annen flens griper omkring randen av dekselet 7- Dette ytre deksel er forsynt med fliker lM som er bøyet inn i vinkel og griper bak fjærende knaster på dekselet, så holdeelementene 12 blir fiksert i forbindelse med en krok 15 på huset. The attachment of the outer cover 7 to the housing 1 takes place by means of two holding elements 12 with a U-shaped cross-section. One flange of this holding element engages in a groove 13 in the housing, while the other flange engages around the edge of the cover 7- This outer cover is provided with tabs 1M which are bent into an angle and engage behind spring-loaded lugs on the cover, so the holding elements 12 is fixed in connection with a hook 15 on the housing.
I de ytre flenser av holdeelementene 12 er der utformet åpninger 16 i området for de nevnte knaster. Skal dekselet 7 tas av, trykker man knastene inn, f.eks. ved å føre stiftene på støpselet på motorens til-førsels ledning inn i åpningene 16, og kan dermed trekke holdeelementene 12 av. Både montering og avmontering av dekselet 7 kan altså gjennom-føres ytterst enkelt. Videre faller både dekselet og holdeelementene enkle i fremstilling, da de kan ha forholdsvis store toleranser. Openings 16 are formed in the outer flanges of the holding elements 12 in the area of the aforementioned knobs. If the cover 7 is to be removed, press the knobs in, e.g. by inserting the pins on the plug on the motor's supply line into the openings 16, and can thus pull the holding elements 12 off. Both assembly and disassembly of the cover 7 can therefore be carried out extremely easily. Furthermore, both the cover and the holding elements are easy to manufacture, as they can have relatively large tolerances.
