Lange transportbånd

  •  

    Enkle, pålitelige, velprøvde løsninger

    Smidig styring av akselerasjonen og retardasjonen for lange transportbånd reduserer mekanisk påkjenning på alle komponenter og på selve transportbåndet. Dette fører til lengre levetid for båndet og andre komponenter, noe som øker ressurstilgjengeligheten og senker vedlikeholds- og driftskostnader. Med fleksibilitet til å styre hastigheten for lange transportbånd kan man begrense flaskehalser og maksimere effektiviteten i en materialflytprosess. Det gir lavere driftskostnader.

    Flere motorer er ofte installert på lange transportbånd. For å sikre pålitelig drift og lengre levetid for båndet er frekvensomformere nødt til å sikre lastdeling mellom hver motor. VLT® og VACON® frekvensomformere omfatter både Master-Master- og Master-Follower-styreløsninger. Valg av styreløsning avhenger av frekvensomformernes konfigurasjon på transportbåndet (for eksempel alle frekvensomformerne i fremre ende eller frekvensomformere både i fremre og bakre ende). De er både enkle å implementere og har vist seg å være robuste, pålitelige løsninger for lange transportører.

    For bakketransportbånd, der kontinuerlig regenerativ bremsekraft gjerne er nødvendig, brukes en AFE-frekvensomformer eller alternativt en regenerativ "drive panel" løsning med en standard 6-pulset frekvensomformer med separat regenerativ modul.

    VLT og VACON frekvensomformere brukes ofte på mange lange transportbånd over 1 km, noe som er vanlig ved bulkmaterialhåndtering ved gruver, bearbeidingsanlegg og havneanlegg så som:

    • containertransportbånd
    • lagringsplasser
    • train loadout conveyors
    • rørtransportbånd
    • lange landtransportbånd
