Abstract

A találmány cseppfolyós vagy gáz halmazállapotú közeget szállító,különösen örvénygépként, úgy mint szivattyúként vagy ventillátorkéntmegvalósított szállítóberendezést meghajtó elektromotorfordulatszámának szabályozására vonatkozik. A szállítóberendezésfogyasztói oldalán a szállítóberendezés által az időben változóteljesítményigény kielégítését a motor fordulatszámával szabályozzák.Az elektromotor fordulatszámát egy szabályozó kimenő értékévelvezérelik. Mérik az elektromotor által felvett áramot és egy amindenkori mért áramot képviselő jelet hoznak létre, amit bemenőértékként vezetnek a szabályozóba. A szabályozóban végzik a bemenőérték automatikus kalibrálását. Ezáltal elmaradnak az áramlástechnikaimérőérzékelők és a hosszú mérővezetékek. Továbbá nincs szükség aberendezés jelleggörbéjének meghatározására, így egyszerűbbé válik aberendezés üzembehelyezése. Az eljárás biztosítja a szabályozásnagyfokú gazdaságosságát és stabilitását. ÓThe invention relates to the control of the speed of an electric motor driving a conveying device that transports a liquid or gaseous medium, in particular as a vortex machine, such as a pump or a fan. On the consumer side of the conveying equipment, the fulfillment of the time-varying power demand by the conveying equipment is controlled by the speed of the motor. The speed of the electric motor is controlled by the output value of a regulator. They measure the current absorbed by the electric motor and create a signal representing the measured current at any given time, which is fed into the controller as an input value. Automatic calibration of the input value is carried out in the regulator. This eliminates the need for flow technology measuring sensors and long measuring lines. Furthermore, there is no need to determine the characteristic curve of the equipment, so the commissioning of the equipment becomes simpler. The procedure ensures a high degree of economy and stability of the regulation. HE
