Opfindelsen omhandler en cirkulationspumpe til centralvarmeanlæg med to hver især afspærrelige pumpeenheder og en udefra regulerbar omløbsventil.The invention relates to a central heating system circulation pump with two separate pump units and an externally adjustable bypass valve.
Fra beskrivelsen til tysk offentliggørelsesskrift nr. 2 344 345 kendes en sådan cirkulationspumpe, hvor der foruden klapventil-legemerne findes en ved en manøvreknap betjent omløbsventil med en fælles virkning på begge centrifugalpumpernes tilgang og afgang.From the description to German publication specification No. 2,344,345, such a circulation pump is known, in which, in addition to the flap valve bodies, there is a bypass valve operated by a maneuver button with a common effect on the access and discharge of both centrifugal pumps.
D I denne pumpe er klapventillegemerne anbragt foroven i pumpehuset jO i højde med afgangskanalen og fastgjort til en første aksel. Af- O gangsvejen består af et hult legeme, der er anbragt på pumpehuset iØ r- 3 2 146663 og forbinder tilgangskanalen med afgangskanalen. Omløbsventilen er fastgjort til den nederste ende af det hule legeme og omfatter den udvendigt anbragte manøvreknap.D In this pump, the flap valve bodies are located at the top of the pump housing j0 at the level of the outlet duct and attached to a first shaft. The exit path consists of a hollow body which is arranged on the pump housing in 3 2 146663 and connects the inlet duct with the outlet duct. The bypass valve is attached to the lower end of the hollow body and comprises the externally arranged maneuver button.
Den kendte pumpemekanisme omfatter således to aksler, der skal monteres særskilt, hvilket komplicerer monteringen, og pumpehusets udformning medfører en ømtålelig formstøbning af to særskilte hul legemer.Thus, the known pumping mechanism comprises two shafts to be mounted separately, which complicates the mounting, and the design of the pump housing results in a delicate molding of two separate hollow bodies.
Opfindelsen har til formål at tilvejebringe en pumpeenhed af den angivne art, der er simplere at fremstille og montere. Dette opnås ifølge opfindelsen ved en konstruktion af den i krav l's kendetegnende del angivne art, hvorved man på én og samme aksel kan montere både klapventillegemerne til afspærring af den enkelte centrifugalpumpe ude af drift, omløbsventillegemet og dettes manøvreknap .The invention has for its object to provide a pump unit of the specified type which is simpler to manufacture and assemble. This is achieved according to the invention by a construction of the character of the characterizing part of claim 1, whereby one and the same shaft can be mounted on both the valve valve bodies for shut-down of the single centrifugal pump out of operation, the bypass valve body and its maneuver button.
Opfindelsen forklares nærmere nedenfor i forbindelse med tegningen , hvor fig. 1 er et tværsnit igennem dobbeltpumpehuset parallelt med dettes forside, og fig. 2 er et lodret længdesnit igennem pumpehuset vinkelret på dettes forside.The invention is further explained below in connection with the drawing, in which fig. 1 is a cross-section through the double pump housing parallel to its front side; and FIG. 2 is a vertical longitudinal section through the pump housing perpendicular to its front.
Fig. 1 er et tværsnit igennem et pumpehus 1 langs et plan, der rummer en fælles akse A-A* for en nedadvendende indsugningszone 2 og en opad-vendende udstødningszone 3» som er udformet symmetrisk i forhold til aksen A-A’ med en indsugningsåbning 5 og en udstødningsåbning 6, hvilke åbninger er fælles for de symmetrisk anbragte dobbeltpumpeelementer, hvoraf der i tværsnittet er vist et højre pumpehus 4 og et venstre pumpehus 4*. Man bemærker den kompakte form af pumpehuset 1, og især den voksende bredde af udstødningszonen 3 under kraven 11 af den øverste åbning 6. Indervæggen af pumpehuset 1 omfatter et indadragende parti i nærheden af mundingerne 13 og 13' for pumpehusene 4 og 4*, hvilket fremspringende parti er begrænset opadtil af en flade 12, der står praktisk taget vinkelret på pumpehusets øverste indervæg 14, og er begrænset nedadtil af pumpehuset 4 eller 4’. Pumpehusene 4 og 4' danner tilsammen med deres mundinger 13 og 13' et legeme 16, hvis inder- 3 146663 væg 15 danner et cirkulært profil omkring et centrum 0 med en øverste åbning 17 og en nederste åbning 18.FIG. 1 is a cross-section through a pump housing 1 along a plane containing a common axis AA * for a downwardly aspirating zone 2 and an upwardly extending ejection zone 3 »formed symmetrically with respect to axis A-A 'with a suction orifice 5 and a exhaust port 6, which openings are common to the symmetrically arranged dual pump elements, of which a right pump housing 4 and a left pump housing 4 are shown in cross section. Notice the compact shape of the pump housing 1, and in particular the growing width of the exhaust zone 3 below the collar 11 of the upper opening 6. The inner wall of the pump housing 1 comprises an inwardly projecting portion in the vicinity of the orifices 13 and 13 'of the pump housings 4 and 4 *, projecting portion is confined upwardly by a surface 12 which is substantially perpendicular to the upper inner wall 14 of the pump housing and is confined downwardly by the pump housing 4 or 4 '. The pump housings 4 and 4 'together with their orifices 13 and 13' form a body 16, the inner wall of which 15 forms a circular profile around a center 0 with an upper opening 17 and a lower opening 18.
I denne dobbeltpumpekonstruktion 1 tilvejebringes der ifølge opfindelsen en cylinderformet styreaksel 20 centreret i centret 0 og koaksialt beliggende med legemet 16. På akselen 20 er der monteret to klapper 8 og 9, der som vist på figuren har en let ombøjning.. Ombøjningen tilvejebringer et korrekt anlæg af bagfladen af hver af klapperne på kanterne af hvert pumpehus's munding, såsom kanterne 19 og 12, på hvilke klapperne ligger an, når de sænkes i lukkestilling.In this double pump construction 1, according to the invention, a cylindrical guide shaft 20 is provided centered in the center 0 and coaxially located with the body 16. Two shafts 8 and 9 are mounted on the shaft 20 which, as shown in the figure, have a slight bending. abutment of the back surface of each of the flaps on the edges of the mouth of each pump housing, such as the edges 19 and 12, on which the flaps abut when lowered in the closing position.
Fig. 2 viser i længdesnit den nærmere udformning af klappen 9 for mundingen 13' af pumpehuset 4' i udstødningszonen 3· Klappens overflade er naturligvis lidt større end den tilknyttede munding for at tilvejebringe en tæt lukning. Som vist på fig. 1 og 2 holdes den øverste flade af hver af klapperne 8 og 9 antrykket af en returfjeder 21, som delvis er omviklet omkring akselen 20. Klapperne 8 og 9 er frit ophængt på akselen 20. Som vist på fig. 2 understøttes hver klap af et par ben 22, som er monteret gnidningsfrit på akselen 20 ved hjælp af to muffer 24 eller 24'. Den frie ende 23 af fjederen 21 lig- * ger an imod forfladen af klappen 9 og kan glide på denne styret af en ribbe 25 på klapfladen. De frie ender 23 af klapfjedrene er ombukket som vist på fig. 1. Benene 26 og mufferne 24' for klappen 8 som vist ved punkterede linier på fig. 2 alternerer med benene 22 og mufferne 24 for klappen 9. Ved monteringen indføres benene 22 og 26 med deres muffer på akselen 20, så at de kan glide frit på denne uden friktion.FIG. 2 shows in longitudinal section the detailed configuration of the flap 9 for the mouth 13 'of the pump housing 4' in the exhaust zone 3 · The flap surface is, of course, slightly larger than the associated mouth to provide a tight closure. As shown in FIG. 1 and 2, the upper surface of each of the flaps 8 and 9 is held in place by a return spring 21 partially wrapped around the shaft 20. The flaps 8 and 9 are freely suspended on the shaft 20. As shown in FIG. 2, each flap is supported by a pair of legs 22 which are mounted smoothly on the shaft 20 by means of two sleeves 24 or 24 '. The free end 23 of the spring 21 abuts against the front of the flap 9 and can slide on it guided by a rib 25 on the flap surface. The free ends 23 of the flap springs are folded as shown in FIG. 1. The legs 26 and the sleeves 24 'of the flap 8 as shown by dashed lines in FIG. 2 alternates with the legs 22 and the sleeves 24 for the flap 9. During assembly, the legs 22 and 26 are inserted with their sleeves on the shaft 20 so that they can slide freely on it without friction.
Endvidere indsættes der i legemet 16 et drejespjæld 10 drejefast på styreakselen 20, sammen med hvilken det kan dreje sig omkring en rotationsakse B-B' vinkelret på aksen A-A' i punktet 0, se fig. 1. Dreje spjældet 10 gøres drejefast med akselen 20 under monteringen ved hjælp af en stiv mekanisk forbindelse, eksempelvis ved nitning eller med en split. Endvidere er den fælles aksel 20 også stift forbundet med en manøvreknap 31 med et håndgreb 32 beliggende uden for huset 1. Den stive forbindelse kan eksempelvis tilvejebringes ved prespasning af styreakselen 20 i manøvreknappen 31, når denne bestyr af et formstøbeligt formstof. Fig. 2 viser to skiver 33 og 34 anbragt på akselen 20 foran og bag ved en fjederklemme 35, der indpresset i en not 36 i akselen 20 fastholder skiverne i stilling. En 0-pakring 4 146663 37 tilvejebringer en fuldstændig tætlukning ud for manøvreknappen 31 mod pumpens forside.Further, a rotary damper 10 is inserted in the body 16 pivotally fixed to the guide shaft 20, along with which it can rotate about a axis of rotation B-B 'perpendicular to the axis A-A' at the point 0, see fig. 1. Turning the damper 10 is pivotally fixed to the shaft 20 during mounting by means of a rigid mechanical connection, for example by riveting or by a split. Furthermore, the common shaft 20 is also rigidly connected to a maneuver button 31 with a handle 32 located outside the housing 1. For example, the rigid connection can be provided by pressing the guide shaft 20 into the maneuver button 31 when it is controlled by a moldable plastic material. FIG. 2 shows two washers 33 and 34 located on the front and rear of shaft 20 by a spring clamp 35 which is pressed into a groove 36 in the shaft 20 holding the washers in position. A 0-packing ring 4 provides a complete closure of the maneuver button 31 towards the front of the pump.
På bagsiden har pumpehuset en bred åbning, som efter den indvendige montering af reguleringsmekanismen ifølge opfindelsen lukkes ved hjælp af en plade 38 ved anlæg imod en plan kantflade 39 ·At the rear, the pump housing has a wide opening which, after the internal mounting of the control mechanism according to the invention, is closed by means of a plate 38 when abutting against a flat edge surface 39 ·
Den færdigtbyggede pumpe er fuldstændig vandtæt og kan udføre to funktioner. Den første funktion består i automatisk regulering af mundingerne af pumpehusene imod udstødningszonen. Såfremt det højre pumpeelement er i funktion, passerer strømmen igennem pumpehuset 4 langs pilretningen F2 på fig. 1, og trykket af fluidet ved mundingen 13 trykker imod bagfladen af klappen 8. Kraften af returfjederen 21 for klappen 8 er beregnet til at ligge lige under fluidumtrykket.The pre-built pump is completely waterproof and can perform two functions. The first function is to automatically regulate the orifices of the pump housings against the exhaust zone. If the right pump element is in operation, the flow passes through the pump housing 4 along the arrow direction F2 in FIG. 1, and the pressure of the fluid at the orifice 13 presses against the back surface of the flap 8. The force of the return spring 21 of the flap 8 is intended to be just below the fluid pressure.
Derved forskydes klappen 8 en vinkel i retning mod aksen A-A* og frigør passagen imod udstødningszonen 3 som vist på fig. 1, hvor mundingen 13 på pumpehuset 4 er åben, men mundingen 13’ for pumpehuset 4' er lukket ved kraften fra returfjederen 21, der ikke modvirkes af noget tryk, fordi det venstre pumpeelement ikke fungerer. Derved undgås enhver fluidumcirkulation i modsat retning i det venstre pumpeelement, som er i hvile.Thereby, the flap 8 is displaced at an angle towards the axis A-A * and releases the passage towards the exhaust zone 3 as shown in FIG. 1, where the orifice 13 of the pump housing 4 is open, but the orifice 13 'of the pump housing 4' is closed by the force of the return spring 21 which is not counteracted by any pressure because the left pump element does not function. Thereby, any fluid circulation in the opposite direction is avoided in the left pumping element which is at rest.
Den anden funktion består i at yde en reguleringsmulighed for pumpe-gennemstrømningen uanset hvilket pumpeelement der fungerer. Det ses, at drejespjældet 10 kan optage alle mulige stillinger i forhold til en åbning 18, der afgrænses af indervæggene 40 og 41 af indsugningskanalen 2.· Når drejespjældet 10 frigør åbningen 18, er der forbindelse imellem indsugningskanalen 2 og udstødningszonen 3 i pilretningen F^. Drejespjældet kan også kun delvis frigøre åbningen eller helt afbryde forbindelsen imellem indsugnings- og udstødnings zonerne i den på. fi,g.The second function is to provide a pump flow control option regardless of which pump element is operating. It will be seen that the damper 10 can occupy all possible positions relative to an opening 18 defined by the inner walls 40 and 41 of the suction duct 2. · When the damper 10 releases the orifice 18, there is a connection between the suction duct 2 and the exhaust zone 3 in the arrow direction F . The rotary damper can also only partially release the opening or completely cut off the connection between the intake and exhaust zones in it. Fi, g.
1 viste stilling, hvor drejespjældet 10 helt lukker åbningen 18. Man-øvreknappen 31 muliggør altså en fuldstændig regulering af gennemstrømningsmængden.1, where the damper 10 completely closes the opening 18. The man-upper knob 31 thus allows a complete control of the flow rate.
Reguleringen sker identisk og samtidigt for de to pumpeelementer af symmetrigrunde. Denne udformning forenkler desuden konstruktionen af dobbeltpumpehuset. Tidligere måtte man i et pumpehus med flere elementer tilvejebringe lige så mange udstødningskanaler som der er pumpeelementer, medens opfindelsen kun kræver én udstødningskanal og dervedThe adjustment is identical and simultaneous for the two pump elements of symmetry. This design further simplifies the construction of the double pump housing. Previously, in a multi-element pump housing, one had to provide as many exhaust ducts as there are pump elements, while the invention required only one exhaust duct and thereby
