Ua tiav zoo
Tus radial runout ntawm tus neeg qis qis tsis muaj peev xwm raug ntsuas los ntawm cov txheej txheem hauv qab no:
Cov kauj khawb induction yog kev zoo siab los ntawm alternating tam sim no thiab tsim ib qho kev sib hloov magnetic.
Thaum hloov xaj hlau sib txuas nrog cov khoom siv (xws li lub taub hau), ib qho me me tam sim no hu ua ib qho kev ua tiav eddy yog vim li cas.
Nyuam qhuav, lub eddy tam sim no ua ib qho kev sib txeeb ntawm kev sib nqus uas tawm tsam thawj lub phom sij.
Kev sib cuam tshuam ntawm ob lub teb chaw magnetic nyob ntawm qhov kev ncua deb ntawm lub txhuas soj ntsuam thiab cov khoom siv khoom. Raws li qhov kev hloov deb, qhov kev hloov hauv kev sib cuam tshuam ntawm ob lub teb chaw magnetic txhais rau hauv qhov tso zis ntawm qhov voltage.
Qhov tso tawm qhov hluav taws xob tau hloov mus rau ib chav tsev ntawm kev hloov chaw mus rau hauv cov mines los yog micrometers.
Ib qho kev teeb pom kev zoo tshaj plaws muaj ob qho kev sib tshooj tam sim no uas tau txhim kho ntawm qhov chaw pw ntawm 90 degrees sib nrug thiab nyob ntawm 45 degrees ntawm ob sab ntawm qhov chaw nruab nrab ntawm lub qhov tob.
Lub tshuab hluav taws xob tau muab ntsia rau sab hauv los yog sab nraud ntawm phau ntawv teev cov kabmob, nyob ntawm qhov tsim ntawm lub tshuab. Lub tshuab ntes tau ntsa nruab nrab ntawm cov ncej thiab nws txoj hauj lwm yog qhia tshwj xeeb uas muaj kev sib txuas thiab nyob ze rau ntawm phau ntawv xov xwm. Qhov no yog ib feem ntawm txoj hlaub, hu ua qhov chaw ntes khiav tawm, yog machined kom ua tiav cov hluav taws xob khiav hluav taws xob thiab hluav taws xob. Qhov dav ntawm thaj chaw khiav yog nyob ntawm qhov loj ntawm lub ntsuas kev sojntsuam. Nws raug pom zoo tias qhov dav ntawm qhov tsawg tshaj plaws ntawm thaj chaw khiav yog 1.5 npaug ntawm qhov ntsuas ntawm kev soj tswb. Qhov no ua kom pom tias qhov magnetic field induced ntawm tus soj ntsuam kev soj ntsuam tau them rau tag nrho cheeb tsam ua machined.
API 541 yuav tsum tau khiav radiator ntawm kev khiav qis qis kom ntsuas thaum lub sij hawm coasting xeem theem ntawm lub rotor ntawm kev ceev ntawm 200 thiab 300 rpm. Hauv kev ceev no, qhov offset kaw los ntawm lub ntes yog yuav luag ntshiab radial runout yam tsis muaj kev vibration. Nyob rau cov tsev qiv ntawv uas tsis yog API, khiav radial ntawm cov qis qis qis yuav raug kaw nyob rau thaj tsam li ntawm 10% mus rau 15% ntawm qhov khiav ceev. Tag nrho cov ntaub ntawv khiav tawm hauv radials tag nrho yuav tsum ua raws li cov kev txwv ntawm cov lus qhia hauv lub cev.
