OPISDESCRIPTION

Predmet izuma je sestav centrifugalne črpalke z elektromotorjem.Subject of the invention is the assembly of a centrifugal pump with an electric motor.

Poznani so sestavi centrifugalnih črpalk, ki sestojijo v bistvu iz votlega telesa, opremljenega s sesalnimi in potisnimi vodi, in vsebujejo enega ali več impelerjev, ki so prepleteni z difuzorji in so pritrjeni na gredi elektromotorja, ki se nahaja v notranjosti okrova motorja, ki le-tega izolira pred črpalno tekočino.They are known in the composition of centrifugal pumps which consist essentially of a hollow body equipped with suction and discharge leads and contain one or more impellers interlaced with diffusers and attached to the shaft of the electric motor located inside the engine housing which -this is isolated from the pumping liquid.

Plošča tiskanega vezja, ki je vsebovana v škatli, napaja in krmili delovanje motorja.The board of the printed circuit board contained in the box supplies and controls the operation of the engine.

Takšne tehnične rešitve imajo kar nekaj slabosti in vidike, ki jih lahko izboljšamo.Such technical solutions have some weaknesses and aspects that can be improved.

Običajno se gred impelerja po dolgih obdobjih neuporabe avtomatično deblokira z elektronskim krmilnim sistemom, vendar pa to ni nujno vedno dovolj.Usually, the impeller shaft is automatically unblocked after a long period of non-use with the electronic control system, but this is not necessarily always sufficient.

Nadalje ima čep, kjer je prisoten, dimenzijo in obliko, zaradi katere ga uporabnik težko doseže.Furthermore, it has a plug, where it is present, a dimension and shape, which makes it difficult for the user to reach it.

Poleg tega ima čep, kjer je prisoten, takšen volumen, da lahko ustvari toplotni most med mokrim območjem in bližnjim območjem, kar povzroči škodo.In addition, the plug where it is present is such a volume that it can create a thermal bridge between the wet area and the surrounding area, causing damage.

Naloga tega izuma je zasnovati sestav centrifugalne črpalke z elektromotorjem, s katerim bo moč izboljšati stanje tehnike po enem ali več od zgoraj navedenih vidikov. V okviru te naloge je predmet izuma zasnovati sestav centrifugalne črpalke z elektromotorjem in elektroniko, ki obsega čep za ročno deblokiranje gredi s strani uporabnika, ki ima bolj kompakten volumen v primerjavi z analognimi črpalkami na trgu.It is an object of the present invention to design a centrifugal pump assembly with an electric motor to improve the state of the art according to one or more of the above aspects. It is within the scope of this assignment that the object of the invention is to design a set of centrifugal pumps with an electric motor and electronics comprising a manually unblocking shaft by a user having a more compact volume compared to analog pumps on the market.

Drugi predmet izuma je zasnovati sestav centrifugalne črpalke z elektromotorjem, pri katerem ima čep takšno obliko in dimenzijo, da ga lahko uporabnik zlahka doseže.Another object of the invention is to design a centrifugal pump assembly with an electric motor in which the plug has such a shape and dimension so that the user can easily reach it.

Nadaljnji predmet izuma je zasnovati sestav centrifugalne črpalke z elektromotorjem, pri katerem ima čep takšno obliko in dimenzijo, da ne ustvarja toplotnih mostov.A further object of the invention is to design a centrifugal pump assembly with an electric motor in which the plug has such a shape and dimension that it does not generate thermal bridges.

Nadalje je predmet izuma odpraviti slabosti iz stanja tehnike na način, ki je alternativen katerim koli obstoječim rešitvam. Še nadaljnji predmet izuma je zasnovati sestav centrifugalne črpalke z elektromotorjem, ki bo zelo zanesljiv, relativno preprost za izdelavo in to po konkurenčnih stroških.Furthermore, it is the object of the invention to remedy the weaknesses of the state of the art in a way that is alternate to any existing solutions. It is still a further object of the invention to design a centrifugal pump assembly with an electric motor that will be very reliable, relatively simple to manufacture at competitive costs.

Ta naloga ter ta in drugi cilji, ki bodo postali bolj jasni v nadaljevanju, so doseženi s sestavom centrifugalne črpalke z elektromotorjem, kije razmeščen v ohišju statorja, v katerem je škatla, ki vsebuje ploščo tiskanega vezja in je zaprta na prostem koncu s pokrovom, nameščena na osnem koncu ohišja statorja, pri čemer sestav črpalke obsega mokro območje, pri čemer je sestav označen s tem, da obsega čep, ki ima na enem koncu obliko, prirejeno za vstavitev v luknjo, ki je v komunikaciji z mokrim območjem, in deluje kot krmilni element toka, in ima na drugem koncu glavo, kije prirejena, dajo uporabnik zlahka doseže, pri čemer ima čep takšno dolžino, daje zunanja površina omenjene glave v nivoju, kije blizu nivoja pokrova škatle v zaprtem stanju.This task and these and other objects which will become more apparent below will be achieved by means of a centrifugal pump assembly with an electric motor disposed in a stator housing in which a carton comprising a printed circuit board is closed and is closed at the free end with a cover, the assembly of the pump comprising a wet area, said assembly comprising a plug having, at one end, a shape adapted to be inserted into a hole in communication with a wet area and operating as the control element of the current, and having a head on the other end, which is adapted, the user can easily reach, the plug having such length, the outer surface of said head is in a level close to the level of the lid of the box in the closed state.

Nadaljnje značilnosti in prednosti izuma bodo bolj jasne iz opisa prednostnega, vendar ne izključnega izvedbenega primera, sestava centrifugalne črpalke z elektromotorjem po izumu, ki bo prikazan, a ne omejujoče, v pripadajočih slikah, na katerih: - Slika 1 prikazuje prečni prerez sestava črpalke po izumu; - Slika 2 prikazuje perspektivni pogled čepa za sestav črpalke po izumu.

Sestav centrifugalne črpalke 10 obsega na enem koncu električno škatlo 13, ki vsebuje ploščo 14 tiskanega vezja, ki je prirejena za krmiljenje in napajanje elektromotoija 19. Električna škatla 13 je izvedena valjasto in je na prostem koncu zaprta s pokrovom 15. Prednostno ima lahko električna škatla 13 tudi drugačno zasnovo.The assembly of the centrifugal pump 10 comprises at one end an electric box 13 comprising a printed circuit board 14 that is adapted to control and power the electromotor 19. The electric box 13 is made cylindrical and is closed at the free end with the cover 15. Preferably, the electric box 13 also a different design.

Zlasti se elektromotor 19 in električna škatla 14 razprostirata vzdolž iste osi X, ki sovpada z vrtilno osjo motorja in impelerja. Elektromotor 19 in električna škatla 14 sta povezana in združena v celoto zaradi prisotnosti vmesnega elementa 16. Vmesni element 16 je prekrivni in/ali povezovalni element in ima cevasto obliko.In particular, the electric motor 19 and the electric box 14 extend along the same axis X, which coincides with the motor axis and impeller rotation axis. The electric motor 19 and the electric box 14 are connected and integrated into the whole due to the presence of the intermediate element 16. The intermediate element 16 is a covering and / or connecting element and has a tubular shape.

Električna škatla 13 in ohišje 11 statorja imata medsebojno komplementarne stične ploskve. Iz električne škatle 13 se razprostira eden ali več prvih zatičev 28, ki so prirejeni za vstavitev v pripadajoče skoznje luknje 29, izvedene na stični ploskvi ohišja 11 statorja. Zatiči 28 so prirejeni za povezavo škatle 13 in ohišja 11 statorja ter za lažjo montažo črpalke 10.The electrical box 13 and the stator housing 11 have complementary contact surfaces. One or more first pins 28 extending from the electric box 13 are adapted to be inserted into the respective through holes 29 carried out on the contact surface of the housing 11 of the stator. The pins 28 are adapted to connect the box 13 and the stator housing 11 and to facilitate the installation of the pump 10.

Analogno ima škatla 13 enega ali več drugih zatičev 30, ki potekajo znotraj škatle 13 in v smeri pokrova 15, pri čemer so konice zatičev prirejene za vstavitev v pripadajoče luknje, ki so prisotne na površini pokrova 15, obrnjeni proti notranjosti škatle 13. Zatiči 30 so prirejeni za povezavo škatle 13 in pokrova 15 ter za lažjo montažo črpalke 10.Analogously, the carton 13 has one or more other pins 30 that extend inside the box 13 and in the direction of the lid 15, wherein the tips of the pins are adapted to be inserted into the respective holes that are present on the surface of the lid 15 facing the inside of the box 13. Pins 30 are adapted to connect the box 13 and the lid 15 and to facilitate the installation of the pump 10.

Električna škatla 13 ima v notranjosti cevasto telo 34 z osjo razširjanja, ki sovpada z osjo X. Cevasto telo 34 poteka od stične ploskve z ohišjem 11 statorja do pokrova 15 električne škatle 13. Na prečnem prerezu cevastega telesa 34 imata tako električna škatla 14 in pokrov 15 skoznjo luknjo 36 z osjo razširjanja, ki sovpada z osjo X.The electric box 13 has a tubular body 34 inside the tubular body 34 with an expansion axis coinciding with the X axis. The tubular body 34 extends from the contact surface to the housing 11 of the stator to the cover 15 of the electric box 13. The cross-section of the tubular body 34 has both an electric box 14 and a lid 15 through a hole 36 with a spreading axis coinciding with the X axis.

Prednostno lahko os razširjanja luknje ne sovpada z osjo X, ampak je vzporedna z njo.Preferably, the hole propagation axis may not coincide with the X axis but is parallel to it.

Skoznja luknja 36 in cevasto telo 34 sta prirejena za vstavitev čepa 35, katerega en konec je v stiku z mokrim območjem. Cevasto telo 34 in luknja 36 pokrova 15 imata takšne dimenzije in oblike, da zagotavljata vprijem in izolacijo plošče 14 tiskanega vezja od mokrega območja tudi v primeru odprtja čepa 35.The through hole 36 and the tubular body 34 are adapted to insert a plug 35, one of which is in contact with the wet area. The tubular body 34 and the hole 36 of the lid 15 are of such dimensions and shapes as to ensure the engagement and insulation of the printed circuit board 14 of the wet area even in the case of opening the plug 35.

Zlasti ima čep 35 na enem koncu obliko 43, ki je prirejena za vstavitev v luknjo, ki je v komunikaciji z mokrim območjem, in deluje kot krmilni element toka, in na drugem koncu glavo 40, ki je prirejena, da jo uporabnik zlahka doseže. Čep 35 ima valjasto obliko in takšno dolžino, daje zunanja površina glave 40 na nivoju, kije blizu nivoja pokrova 15 škatle 13 v zaprtem stanju. Oblika 43 obsega kolutast končni element 47, ki se nadaljuje v luknjo, ki je v komunikaciji z mokrim območjem, z navojnim elementom 42, ki je prirejen, da določa pritrditev čepa 35 v luknji, ki ima komplementaren navoj. Kolutasti element 47 ima dimenzije, ki so enake ali primerljive z dimenzijami glave 40.In particular, there is a plug 35 at one end of a shape 43 which is adapted to be inserted into a hole in communication with the wet area and acts as a control element of the current, and at the other end a head 40 adapted to be easily accessible by the user. The plug 35 has a cylindrical shape and such a length that the outer surface of the head 40 is at a level close to the level of the lid 15 of the box 13 in the closed state. Form 43 comprises a discontinuous end element 47 which extends into a hole in communication with the wet region with a threaded element 42 adapted to determine the attachment of the plug 35 into the hole having a complementary thread. The wheel 47 has dimensions that are the same or comparable to the dimensions of the head 40.

Glava 40 je kolutasta in ima zarezo 44, prirejeno za vstavitev konice izvijača, da omogoča odvitje in privitje.Head 40 is coil and has a slot 44 adapted to insert the screw tip of the screwdriver to allow unwinding and tightening.

Po enem izvedbenem primeru čep 35 obsega element za pokritje čepa, ki na slikah ni viden, da pokrije prisotnost čepa in ustvari prijetnejši vizualni vtis. Čep 35 ima vmesni odsek 41, ki je tudi kolutast in dimenzij, podobnih dimenzijam glave 40, da olajša vstavitev čepa v luknjo 36 in v cevasto telo 34.According to one embodiment, the plug 35 comprises a cover cap which is not visible in the figures to cover the presence of a plug and create a more pleasant visual impression. The plug 35 has an intermediate portion 41 which is also a disc and dimensions similar to the dimensions of the head 40 to facilitate inserting the plug into the hole 36 and into the tubular body 34.

Med glavo 40 in vmesnim elementom 41 je razmeščen prvi cevasti odsek 45 s premerom, ki je manjši od premera glave 40. Med vmesnim elementom 41 in končnim elementom 47 je razmeščen drugi cevasti odsek 46 s premerom, ki je manjši od premera prvega cevastega odseka 45.Between the head 40 and the intermediate element 41, a first tubular section 45 with a diameter smaller than the diameter of the head 40 is disposed. A second tubular section 46 having a diameter smaller than the diameter of the first tubular section 45 is disposed between the intermediate element 41 and the end element 47 .

Prisotnost teh valjastih odsekov z zmanjšanim premerom omogoča, da se ognemo toplotnim mostovom in omogoča, da dobimo čep, ki je lažji, stroški pa so enaki. Čep 35 je narejen iz medenine s struženjem in vsi njegovi deli, ki so na sliki 2 označeni s številkami od 40 do 47, so dobljeni iz enega samega telesa.The presence of these cylindrical sections with reduced diameter makes it possible to heat the heat bridges and enable us to get a plug that is lighter and the costs are the same. The plug 35 is made of brass with turning and all of its parts, which are numbered 40 to 47 in figure 2, are obtained from a single body.

Prednostno je lahko čep 35 narejen iz nerjavnega jekla.Preferably, the plug 35 can be made of stainless steel.

Tesnjenje med mokrim območjem in čepom 35 je zagotovljeno z O-obročem 37 znanega tipa, tesnjenje med mokrim območjem, električno škatlo 13 in ohišjem 11 statorja pa je zagotovljeno s tesnilom 38 znanega tipa.Sealing between the wet area and the plug 35 is provided with a known O-ring 37 of the known type, sealing between the wet area, the electric box 13 and the stator housing 11 being provided with a seal 38 of the known type.

Iz plošče 14 tiskanega vezja se razprostirajo moške priključne ploščice 24, ki so prirejene za vstavitev v ženske priključne sponke 25, ki so povezane z elektromotorjem 19. Tako lahko plošča 14 napaja in krmili elektromotor 19.From the printed circuit board 14, the male connection plates 24 are arranged which are adapted for insertion into the female terminal blocks 25 connected to the electric motor 19. Thus, the plate 14 can be fed and controlled by an electric motor 19.

Plošča 14 tiskanega vezja ima na enem koncu konektor 26, ki je prirejen za vstavitev v priključek za napajanje z elektriko, ki se nahaja izven črpalke. Na območju vstavitve priključka ima škatla 13 jeziček 27, ki štrli glede na vmesni element 16.The printed circuit board 14 has at its one end a connector 26 which is adapted to be inserted into an electrical supply connector located outside the pump. In the region of insertion of the connector, the box 13 has a tab 27 projecting with respect to the intermediate element 16.

Treba je povedati, da prisotnost čepa po izumu omogoča, da uporabnik ročno deblokira impeler skozi gred.It should be noted that the presence of a plug according to the invention allows the user to manually unblock the impeller through the shaft.
