Tsav suab thiab suab nrov txo ntsuas
Kev tswj lub suab nrov yog qhov tseem ceeb ntawm kev tiv thaiv ib puag ncig, thiab lub suab nrov nrov yog qhov tseem ceeb ntawm kev ntsuas los ntsuas qhov zoo ntawm cov khoom siv cav. Yog li ntawd, tswj lub suab nrov ntawm lub cev tau ua ib qho teeb meem tseem ceeb rau kev muaj sia nyob thiab kev loj hlob ntawm lub tshuab tsav tsheb hauv tsev thiab nyob sab nraud. Tsab ntawv tshawb fawb thiab sib tham txog qhov tseem ceeb ntawm cov suab nrov thiab suab nrov txo kev ntsuas.
Thaum lub cav khiav, muaj ntau lub suab nrov sib txawv nyob rau tib lub sijhawm. Cov suab nrov sib txawv yog tsim los ntawm ntau qhov chaw ntawm lub cav, thiab qhov sib txawv ntawm lub tshuab ua suab nrov yog feem ntau tsis meej, yog li lawv muaj peev xwm raug kawm thiab cais tawm suab nrov. .
1, suab nrov electromagnetic
Electromagnetic suab nrov yog vim los ntawm kev hloov hauv sij hawm thiab qhov chaw, thiab yog tshwm sim los ntawm kev sib zog nqus rub tawm dag zog ntawm ntau qhov chaw ntawm lub tshuab. Lub sib nqus teb nyob rau hauv qhov chaw sib nraus ntawm qhov sib txawv ntawm huab cua yog lub zog quab yuam nws qhov radial quab yuam yoj ua rau radial deformation thiab periodic kev vibration ntawm tus stator thiab rotor, thiab yog lub suab rau kev ua suab nrov. Feem ntau ntawm nws lub suab tsis muaj suab npe los ntawm tus stator thiab lwm yam khoom rau qhov chaw nyob, ua "nrov nrov", thiab feem ntau ntawm lub suab nrov electromagnetic yog "tsis hnov suab nrov." Muaj ntau ntau yam kev tsim thiab kev poob haujlwm, uas tseem ua rau kev nce suab hauv tshuab electromagnetic, xws li: sib nqus nro tsis txaus; cawv ntawm kev ua dej num loj; nyhuv ntawm qhib qhov qhib; suab nrov tau los ntawm lub qhov oscillation; dynamic eccentricity ntawm huab cua sib txawv; pulsation nyob rau thyristor zog mov Cheebtsam; harmonic tivthaiv rau hauv daim phiaj fais fab; asynchronous lub puab tsaig tawg nti; DC tsav qis thiab tus ncej ntawm tus ncej tig mus rau sab nraud; AC motor core pressing tsis nruj; sib dhos cua sib txawv yog tsis sib txig. Yog li, cia kom tsis txhob muaj qhov sib txawv ntawm cov pa sib txawv ntawm lub cev thiab ua rau kom tsis muaj pa taws ntxiv. Yog hais tias siv fais fab siv rau kev tsim, cov pa hluav taws tsis sib haum ntawm DC lub cev thiab cov hlau nplaum ntawm AC lub cev muaj peev xwm txo cov suab sib tov thiab electromagnetic suab ntawm tus hniav. Pom zoo. Ua kom lub rigidity ntawm tus ncej tuaj yeem txo qhov kev vibration thiab suab nrov generated los ntawm txoj kev siv qhov kev sib hloov hauv kev lag luam hauv lub stator thiab rotor air gap fields. Kev txhim kho lub davhlau ntawm qhov sib txawv ntawm qhov sib txawv ntawm huab cua thiab qhov zoo ntawm qhov tseem ceeb ntawm cov tub ntxhais kawm yog txhua yam siv los txo cov suab nrov hauv electromagnetic.
