Cummins diesel generator sets yog dav siv nyob rau hauv lub teb ntawm backup fais fab mov thiab lub ntsiab chaw nres tsheb fais fab, nrog rau ntau yam ntawm lub hwj chim kev pab them nqi, ruaj khov kev ua tau zoo, advanced technology, thiab lub ntiaj teb no kev pab cuam system.
Feem ntau hais lus, Cummins generator teeb gen-set vibration yog tshwm sim los ntawm qhov tsis sib xws rotating qhov chaw, electromagnetic yam lossis mechanical failures.
Qhov tsis sib npaug ntawm qhov rotating feem ntau yog tshwm sim los ntawm qhov tsis sib xws ntawm lub rotor, txuas txuas, txuas thiab kis lub log (brake log).Txoj kev daws teeb meem yog nrhiav qhov sib npaug rotor ua ntej.Yog tias muaj lub log loj loj, lub log nres, cov hlua khi, thiab cov couplings, lawv yuav tsum tau muab cais tawm ntawm lub rotor kom pom qhov sib npaug zoo.Tom qab ntawd muaj cov neeg kho tshuab loosening ntawm rotating ib feem.Piv txwv li, lub looseness ntawm cov tub ntxhais hlau bracket, tsis ua hauj lwm ntawm oblique qhov tseem ceeb thiab tus pin, thiab xoob khi ntawm lub rotor yuav ua rau lub unbalance ntawm lub rotating ib feem.
Qhov tsis ua haujlwm ntawm cov khoom siv hluav taws xob yog tshwm sim los ntawm cov khoom siv hluav taws xob, uas feem ntau suav nrog: luv luv Circuit Court ntawm rotor winding ntawm lub qhov txhab asynchronous lub cev muaj zog, tsis raug xaim ntawm AC lub cev muaj zog stator, luv luv Circuit Court ntawm lem ntawm excitation winding ntawm synchronous generator, tsis ncaj ncees lawm kev twb kev txuas ntawm excitation coil. ntawm synchronous lub cev muaj zog, tawg rotor bar ntawm tawb hom asynchronous lub cev muaj zog, stator thiab rotor cua tshwm sim los ntawm deformation ntawm rotor core.Qhov sib txawv tsis sib xws, ua rau huab cua sib nqus sib nqus flux tsis sib npaug thiab ua rau muaj kev vibration.
Lub ntsiab ua txhaum ntawm lub vibration machinery ib feem ntawm Cummins generator teeb yog: 1. Cov ncej ntawm qhov txuas ntawm qhov txuas tsis sib haum, thiab cov kab hauv nruab nrab tsis sib xws, thiab qhov chaw nruab nrab tsis raug.2. Lub zog thiab couplings txuas nrog lub cev muaj zog yog faulty.3. Cov teeb meem ntawm cov qauv ntawm lub cev muaj zog nws tus kheej thiab teeb meem kev teeb tsa.4. Load conduction vibration tsav los ntawm lub cev muaj zog.
