Mphete yokhazikika MTE01082-01

Mphete yokhazikika imagwira ntchito yofunika kwambiri poletsa kupangika ndi kusonkhana kwa magetsi a shaft ndi ma bearing currents—mavuto awiri ofala koma owononga makina ozungulira monga ma motors ndi ma jenereta. Magetsi a shaft nthawi zambiri amachokera ku zotsatira za electromagnetic induction mkati mwa makina, monga kugawa kwa maginito osafanana mu stator core, kulumikizana kwa capacitive pakati pa stator windings ndi rotor, kapena ma voltage otsalira ochokera ku variable frequency drives (VFDs) omwe amapatsa mphamvu ma motors ambiri amakono amakampani. Magetsi awa akamasonkhana pa shaft, amatha kupitirira mphamvu ya dielectric ya filimu yopaka mafuta mu ma bearing a makina. Mukadutsa malire awa, kutuluka kumachitika, zomwe zimadziwika kuti bearing current. Mafunde awa, ngakhale nthawi zambiri amakhala ochepa, amakhala ochulukirapo, ndipo pakapita nthawi, amawononga njira zoyendera ma bearing ndi zinthu zozungulira, zomwe zimapangitsa kuti ma bearing raceways agwe, agwe, komanso alephere kugwira ntchito kwa bearing isanafike nthawi yogwira ntchito. Pazochitika zazikulu, izi zitha kubweretsa nthawi yosayembekezereka ya makina, kukonza kokwera mtengo, komanso kuwonongeka kwachiwiri kwa zida zolumikizidwa mu mzere wopanga.
