Met olie afgedichte draalschulfvacuümpomp met aandrijfmotor in een hulsOil-sealed rotary piston vacuum pump with drive motor in a sleeve
De uitvinding heeft betrekking op een met olie afgedichte draaischuifvacuümpomp, waarbij het pompstelsel en de elektrische aandrijfmotor, in het bijzonder een wisselstroommotor, zich in een huis bevinden en met 5 olie zijn bedekt en waarbij op de pompas buiten de aandrijfmotor een elektrische generator is aangebracht.The invention relates to an oil-sealed rotary vane vacuum pump, in which the pump system and the electric drive motor, in particular an AC motor, are located in a housing and are covered with oil and wherein an electric generator is arranged on the pump shaft outside the drive motor.
Een dergelijke draaischuifvacuümpomp is bekend uit de Duitse octrooiaanvrage 2.620.375, waarin een draaischuifvacuümpomp wordt beschreven die met olie is afgedicht en door een direct gekoppelde aandrijfmotor wordt aangedreven. Daarbij zijn het pompstelsel en de elektrische aandrijfmotor in een gemeenschappelijk huis ondergebracht, dat zo ver met olie is gevuld, dat beide aggregaten in olie lopen.Such a rotary vane vacuum pump is known from German patent application 2,620,375, which describes a rotary vane vacuum pump which is oil-sealed and driven by a directly coupled drive motor. The pump system and the electric drive motor are housed in a common housing which is filled with oil to such an extent that both aggregates run in oil.
10 Ter bewaking van het toerental is op de pompas bovendien een elektrische generator aangebracht.10 An electrical generator is additionally mounted on the pump shaft to monitor the speed.
Voor het aanlopen van de pomp is alleen reeds voor het versnellen van de roterende delen een hoger draaimoment noodzakelijk dan voor het bedrijf van het nominale toerental het geval is. Als echter het pompstelsel en de aandrijfmotor zoals in het hier beschreven geval volledig met olie zijn bedekt en derhalve alle roterende delen in olie lopen, is een aanzienlijk extra draaimoment voor het aanlopen noodzakelijk om 15 de taaiheid van de olie te overwinnen.Starting up the pump requires a higher torque to accelerate the rotating parts than is the case for operating the rated speed. However, if the pump system and the drive motor, as in the case described here, are completely covered with oil and therefore all rotating parts run in oil, a considerable additional torque for starting up is necessary to overcome the toughness of the oil.
Dit is nog sterker merkbaar in koude toestand, als de taaiheid van de olie bijzonder groot is. Een aandrijfmotor, in het bijzonder een wisselstroommotor alleen voor de korte tijdperiode van het aanlopen te ontwerpen zou een sterke overdimensionering betekenen ten opzichte van het continu bedrijf van de pomp. Behalve de nadelen van een ruimtelijk ongunstiger bouw, hogere kosten, hoger energieverbruik en hogere 20 lawaaibelasting treedt hierbij in het bijzonder het probleem op van een te grote warmteontwikkeling. Met het oog op de toegepaste olie mag een bepaalde temperatuur (bijvoorbeeld 100°C) niet worden overschreden.This is even more noticeable in the cold state, when the toughness of the oil is particularly great. To design a drive motor, in particular an AC motor only for the short start-up period, would mean a significant oversizing relative to the continuous operation of the pump. In addition to the disadvantages of a spatially less favorable construction, higher costs, higher energy consumption and higher noise load, the problem of excessive heat development arises in particular. In view of the oil used, a certain temperature (for example 100 ° C) must not be exceeded.
Om het draaimoment van een wisselstroommotor, die voor continu bedrijf is ontworpen, gedurende de aanlooptijd van de pomp te vergroten, kan een extra aanloopcondensator met de bedrijfscondensator parallel worden geschakeld (zie AEG-Telefunken-Handboeken 4 "Einphasenmotoren”).To increase the torque of an AC motor, which is designed for continuous operation, during the start-up time of the pump, an additional starting capacitor can be connected in parallel with the running capacitor (see AEG-Telefunken Handbooks 4 "Single-phase motors").
25 Na het overschrijden van het kipmoment van de aandrijfmotor dat overeenkomt met het hoogste draaimoment dat deze kortstondig kan opbiengen, wordt de aanloopcondensator weer uitgeschakeld om een oververhitting van de motor te vermijden.25 After exceeding the tipping torque of the drive motor that corresponds to the highest torque that it can produce for a short time, the starting capacitor is switched off again to avoid overheating of the motor.
Het uitschakelen van de aanloopcondensator geschiedt volgens de huidige stand van de techniek ofwel door met middelpuntvliedende kracht werkende schakelaars, stroomrelais of tijdrelais.The start-up capacitor is switched off according to the current state of the art either by centrifugal force switches, current relays or time relays.
30 Om een universele toepassing van draaischuifvacuüm pompen te waarborgen moeten deze voor verschillende netspanningen en -frequenties geschikt zijn. Deze eis en de door de bouw van de draaischuifvacuümpomp bepaalde feiten leiden echter bij toepassing van een van de drie gebruikelijke uitschakel-elementen tot de volgende nadelen:30 To ensure universal use of rotary vane vacuum pumps, they must be suitable for different mains voltages and frequencies. However, this requirement and the facts determined by the construction of the rotary vane vacuum pump lead to the following disadvantages when using one of the three usual tripping elements:
Met middelpuntvliedende kracht werkende schakelaars: 35 De toepassing van met middelpuntvliedende kracht werkende schakelaars, die onder olie werken, leidt tot enige problemen. Bijvoorbeeld treedt een isolatie van de contacten door de olie op; verder wordt het moeilijk de bewegende delen in de olie, als gevolg van zijn taaiheid, exact te schakelen. Bij inbouw van met middelpuntvliedende kracht werkende schakelaars krijgt de motor een grotere bouwlengte, wat naast ongunstige ruimtelijke omstandigheden ook negatieve gevolgen voor de looprust heeft.Centrifugal Switches: The use of centrifugal switches operating under oil creates some problems. For example, insulation of the contacts by the oil occurs; furthermore, it becomes difficult to switch precisely the moving parts in the oil due to its toughness. When the switches are operated with centrifugal force, the motor has a longer construction length, which in addition to unfavorable spatial conditions also has negative consequences for the running rest.
40 Een verder nadeel van met middelpuntvliedende kracht werkende schakelaars is, dat zij als zij op een bepaald toerental zijn ingesteld, bij dit toerental schakelen, onafhankelijk van het feit, met welke frequentie de motor wordt bedreven. Het kipmoment van de motor en daarmee het tijdstip waarmee de aanloopcondensator moet worden uitgeschakeld, is echter afhankelijk van de frequentie, waarmee de motor wordt bedreven.A further drawback of centrifugal force switches is that, when set to a certain speed, they switch at this speed, regardless of the frequency at which the motor is operated. However, the tipping moment of the motor and thus the time at which the starting capacitor must be switched off depends on the frequency with which the motor is operated.
45 Stroomrelais:45 Current relay:
De toepassing van stroomrelais heeft het nadeel, dat voor elke spanning en frequentie een ander type moet worden gebruikt, om het tijdstip van het schakelen nauwkeurig in de hand te kunnen houden.The use of current relays has the drawback that a different type must be used for each voltage and frequency in order to accurately control the time of switching.
Tijdrelais:Time relay:
Bij tijdrelais treden dezelfde nadelen op als bij stroomrelais, omdat zij eveneens van de spanning en de 50 frequentie afhankelijk zijn. Een extra nadeel hierbij is, dat de tijd vast is ingesteld, dat wil zeggen als de aanlooptijd door bepaalde randvoorwaarden verandert, bijvoorbeeld door temperatuursveranderingen, kan het schakelpunt niet optimaal worden aangehouden. Bijvoorbeeld kan bij verlaat uitschakelen van de aanloopcondensator oververhitting van de wikkeling optreden.The same disadvantages occur with time relays as with current relays, because they also depend on the voltage and the frequency. An additional drawback here is that the time is fixed, that is to say, if the start-up time changes due to certain limiting conditions, for example due to temperature changes, the switching point cannot be optimally maintained. For example, when the starting capacitor is switched off, the winding may overheat.
De uitvinding beoogt thans een bij alle bedrijfsomstandigheden optimaal uitgevoerde éénfase-aandrijving 55 voor met olie afgedichte draaischuifvacuümpompen met geïntegreerde aandrijfmotor te verschaffen. Hierbij moet er rekening mee worden gehouden, dat het pompstelsel en de aandrijfmotor zich in een gemeenschappelijk huis bevinden en met olie zijn bedekt.The object of the invention is now to provide an optimally designed single-phase drive 55 for oil-sealed rotary vane vacuum pumps with integrated drive motor, which is optimally designed in all operating conditions. It must be taken into account that the pump system and the drive motor are located in a common housing and are covered with oil.
