Claims (13)
1. Fremgangsmåde til standsning af en nedsænkelig pumpe, når pumpen snorker, hvor pumpen er operativt forbundet med en styreenhed, hvor fremgangsmåden er kendetegnet ved de følgende trin: - regulering, ved hjælp af styreenheden, af pumpens driftshastighed for at styre en gennemsnitlig effekt af pumpen mod et forudbestemt fast niveau, - bestemme, om pumpens momentaneffekt befinder sig uden for et forudbestemt område, ved overvågning af mindst en af parametrene: effekt [P], strøm [I] og effektfaktor [οοεφ], - bestemme, om pumpens driftshastighed tiltager, og - standse pumpen på grund af snorken, ved hjælp af styreenheden, når pumpens momentaneffekt bestemmes til at være uden for det forudbestemte område på samme tid, som pumpens driftshastighed bestemmes som være tiltagende.
2. Fremgangsmåde ifølge krav 1, hvor trinnet med bestemmelse, om pumpens driftshastighed tiltager, udføres efter en bekræftende bestemmelse om, at pumpens momentaneffekt befinder sig uden for det forudbestemte område.
3. Fremgangsmåde ifølge krav 1 eller 2, hvor trinnet med bestemmelse, om pumpens driftshastighed tiltager, udføres ved overvågning af en tendens til ændring af pumpens driftshastighed.
4. Fremgangsmåde ifølge krav 3, hvor overvågningen af tendensen til ændring af pumpens driftshastighed udføres med de følgende trin: - måling af en flerhed af momentane driftshastigheder [n1, n2, n3, n4, ...] af pumpen i et forudbestemt tidsrum [t], - sammenligning af det indbyrdes forhold af hvert par tilgrænsende momentane driftshastigheder [n1 ;n2, n2;n3, n3;n4,...j, - overvågning af antallet af gange [m], som en efterfølgende momentan driftshastighed [n2] af et par tilgrænsende momentane driftshastigheder [n1 ;n2j) er større end en foregående momentan driftshastighed [n 1 ] af parret af tilgrænsende momentane driftshastigheder [n1;n2], og - bekræftelse af, at pumpens driftshastighed tiltager, når det antal afgange [m] den efterfølgende momentane driftshastighed [n2] er større end den foregående momentane driftshastighed [n 1 ] er større end en forudbestemt tærskel, i et forudbestemt tidsrum [t],
5. Fremgangsmåde ifølge krav 4, hvor flerheden af momentane pumpehastigheder [n1, n2, n3, n4, ...] er lig med eller større end ti.
6. Fremgangsmåde ifølge krav 4 eller 5, hvor den forudbestemte tærskel af det overvågede antal gange [m], den efterfølgende momentane driftshastighed [n2] er større end den foregående momentane driftshastighed [n1 ] er større end fire.
7. Fremgangsmåde ifølge et hvilket som helst af kravene 4-6, hvor det forudbestemte tidsrum [t] er lig med eller større end to sekunder, og lig med eller mindre end fem sekunder.
8. Fremgangsmåde ifølge krav 1 eller 2, hvor trinnet med bestemmelse, om pumpens driftshastighed tiltager, udføres med overvågning af det tidspunkt, hvor pumpens momentane driftshastighed er større end en forudbestemt tærskel.
9. Fremgangsmåde ifølge et hvilket som helst af de foregående krav, hvor den øvre grænse af det forudbestemte område af pumpens momentaneffekt er lig med eller større end en faktor 1,02 gange det forudbestemte faste niveau af pumpens gennemsnitlige effekt.
10. Fremgangsmåde ifølge et hvilket som helst af de foregående krav, hvor den nedre grænse af det forudbestemte område af pumpens momentaneffekt er lig med eller mindre end en faktor 0,98 gange det forudbestemte faste niveau af pumpens gennemsnitlige effekt.
11. Fremgangsmåde ifølge et hvilket som helst af de foregående krav, hvor pumpen, efter den er stoppet på grund af snorken, holdes inaktiv i en forudbestemt pausetid.
12. Fremgangsmåde ifølge et hvilket som helst af kravene 1-11, hvor pumpen, efter den er stoppet på grund af snorken, holdes inaktiv, indtil styreenheden får et startsignal fra en niveausensor.
13. Fremgangsmåde ifølge et hvilket som helst af de foregående krav, hvor styreenheden udgøres afen drivindretning med variabel frekvens [VFD],
