Description
Anordning ved elektromotor-drevet væskekjølt pumpe. Device for electric motor-driven liquid-cooled pump.
Den foreliggende oppfinnelse angår en anordning ved en elektromotor-drevet væskekjølt pumpe. The present invention relates to a device for an electric motor-driven liquid-cooled pump.
Mer spesielt går oppfinnelsen ut på en More particularly, the invention concerns a
pumpe av den type hvor motorens aksel i pumpens arbeidsstilling er anordnet vertikalt, og hvor væskekjølingen av motoren bevirkes ved hjelp av den pumpede væske, samtidig som pumpen er forsynt med et temperaturfølsomt organ innrettet til ved overskridelse av en viss temperatur av de deler av pumpen som grenser til organet, å utløse en bryter i motorkretsen for å avbryte strømtilførselen. pump of the type where the motor's shaft in the pump's working position is arranged vertically, and where the liquid cooling of the motor is effected by means of the pumped liquid, at the same time that the pump is provided with a temperature-sensitive device designed for exceeding a certain temperature of the parts of the pump which adjacent to the body, to trip a switch in the motor circuit to interrupt the power supply.
Pumper av den nevnte type kan f. eks. anvendes som lensepumper innen bygnings-industrien eller for pumping av avløpsvann. Pumps of the aforementioned type can e.g. used as bilge pumps in the construction industry or for pumping waste water.
Pumpene arbeider ofte i lengere tid The pumps often work for a longer time
uten ettersyn, og der foreligger risiko for at kjølesystemet vil bli tilstoppet av slam, eller at pumpen kommer til å arbeide uten væsketransport. without inspection, and there is a risk that the cooling system will become clogged with sludge, or that the pump will work without liquid transport.
Hvis temperaturen hos det temperatur-følsomme organ i slike tilfeller overstiger den kritiske verdi, vil strømtilførselen au-tomatisk bli brudt. If the temperature of the temperature-sensitive organ in such cases exceeds the critical value, the power supply will automatically be interrupted.
De hittil kjente pumpekonstruksjoner The previously known pump constructions
har for det meste vært forsynt med ett eneste temperaturfølsomt organ, som da har vært anordnet inntil det pumpeelement som erfaringsmessig har vist seg å være mest utsatt for skader som følge av uteblitt kjøling. have for the most part been provided with a single temperature-sensitive organ, which has then been arranged next to the pump element which experience has shown to be most susceptible to damage as a result of a lack of cooling.
Imidlertid har der ofte kunnet oppstå However, that has often been able to occur
skader på flere forskjellige steder i pumpen uten at faren derfor har vært størst på noe bestemt sted. I slik tilfeller har det vært nødvendig å forsyne pumpen med flere damage in several different places in the pump without the danger having therefore been greatest in any particular place. In such cases, it has been necessary to supply the pump with more
temperaturfølsomme organer, som uav-hengig av hverandre har kunnet avbryte strømtilførselen til motoren. Slike pumper får imidlertid betydelig mer innviklet kon-struksjon, hvorfor de blir mer kostbare i anskaffelse og vedlikehold. temperature-sensitive organs, which independently of each other have been able to interrupt the power supply to the motor. However, such pumps have a significantly more complicated construction, which is why they become more expensive to acquire and maintain.
Hensikten med den foreliggende oppfinnelse er å unngå disse ulemper ved den pumpetype hvor der er fare for skade på flere steder i pumpen hvis kjølingen blir utilstrekkelig, og dette formål oppnås ifølge opfinnelsen ved at elektromotorens øvre aksel-ende er lagret i et lager som er plasert i umiddelbar nærhet av såvel motorens rotor som dens statorvikling, og det temperaturfølsomme organ er montert i umiddelbar nærhet av det nevnte lager. The purpose of the present invention is to avoid these disadvantages of the type of pump where there is a risk of damage in several places in the pump if the cooling becomes insufficient, and this purpose is achieved according to the invention by the upper shaft end of the electric motor being stored in a bearing that is placed in the immediate vicinity of both the motor's rotor and its stator winding, and the temperature-sensitive member is mounted in the immediate vicinity of the aforementioned bearing.
En utførelsesform av oppfinnelsen vil bli beskrevet nærmere under henvisning til tegningen, som viser skjematisk lengde-snitt av den øvre del av en elektromotor-drevet væskekjølt lensepumpe. An embodiment of the invention will be described in more detail with reference to the drawing, which shows a schematic longitudinal section of the upper part of an electric motor-driven liquid-cooled bilge pump.
På tegningen betegner 1 den i arbeids-stillingen øvre ende av motorens rotor-aksel, 2 denne aksel-endes lager, 3 rotor-lamellpakken, 4 statorlamellpakken, 5 sta-torviklingen, 6 motorkapselen og 7 en kjøle-kanal som omgir statormantelen. Ifølge opfinnelsen er en temperaturavhengig f øler kropp 8 av i og for seg kjent type fes-tet i den øvre endevegg av kapselen 6 i nærheten av kulelageret 2 og statorviklin-gen 5. Følerlegmet 8 påvirker en ovenfor-liggende trepolet bryter 10, som dekkes av en kappe 9 og er innkoblet i motorens matestrømkrets, slik at denne brytes i alle faser ved overskridelse av en på forhånd bestemt, maksimalt tillatt arbeidstempera-tur av vedkommende motorenheter, nemlig rotoren 3, statoren 4 og kulelageret 2, idet opvarmningen av disse enheter forplantes til legemet 8 ved hjelp av såvel stråling som ledning. In the drawing, 1 denotes the upper end of the motor's rotor shaft in the working position, 2 the bearing of this shaft end, 3 the rotor lamella pack, 4 the stator lamella pack, 5 the stator winding, 6 the motor capsule and 7 a cooling channel that surrounds the stator jacket. According to the invention, a temperature-dependent sensor body 8 of a per se known type is attached to the upper end wall of the capsule 6 in the vicinity of the ball bearing 2 and the stator winding 5. The sensor body 8 affects an upper three-pole switch 10, which is covered of a jacket 9 and is connected to the motor's supply current circuit, so that this is broken in all phases when a pre-determined, maximum permitted working temperature of the motor units in question is exceeded, namely the rotor 3, the stator 4 and the ball bearing 2, as the heating of these units is propagated to the body 8 by means of both radiation and conduction.
Det vil sees at den høyeste temperatur i almindelighet vil forekomme i kapselens øvre del, hvorfor ett eneste følerlegeme med omtrent den viste plasering er fullt ut til-strekkelig for at frakobling skal inntreffe innen noen motorenhet har antatt utillade-lig høy temperatur. It will be seen that the highest temperature will generally occur in the upper part of the capsule, which is why a single sensor body with approximately the location shown is fully sufficient for disconnection to occur before any engine unit has assumed an unacceptably high temperature.
Opfinnelsen er selvsagt ikke begrenset til den viste utførelsesform, som nærmest tar sikte på en trefaset asynkronmotor med rotor av kortslutningstypen. Ved andre strømmatningsforhold kommer selvsagt til-svarende modifiserte motor- og/eller bry-tertyper i betraktning. The invention is of course not limited to the embodiment shown, which mostly aims at a three-phase asynchronous motor with a rotor of the short-circuit type. In the case of other power supply conditions, correspondingly modified motor and/or switch types are of course taken into account.
Følerlegemets plasering kan varieres, f. eks. kan det henlegges til statormantel-ens kjølekanal, hvorved der fås rask indi-kering av uteblitt kjølemedium. The location of the sensor body can be varied, e.g. it can be connected to the stator jacket's cooling channel, whereby there is a quick indication of missing cooling medium.
Det vil forstås at følerlegemet også gjør tjeneste som vern for motoren ved viklings-kortslutning, overbelastning (f. eks. hvis pumpehjulet blir stående fast), fasebrudd i den trefasede matning, etc. It will be understood that the sensor body also serves as protection for the motor in case of winding short-circuit, overload (e.g. if the impeller becomes stuck), phase failure in the three-phase supply, etc.
