Ib qho kev tswj nruj nruj feem ntau muaj xws li kev tswj nruj, tus nyeem ntawv nro, lub ntsuas qhov nro, nres, thiab clutch. Raws li lub voj, nws tuaj yeem muab faib ua qhib - voj, kaw- voj, lossis pub dawb- voj nro tswj tshuab; Raws li txoj kev saib xyuas rau cov ntaub ntawv yob sib txawv, nws tuaj yeem muab faib ua ultrasonic, ntab cov menyuam, thiab taug qab hom caj npab, thiab lwm yam.
Cov txheej txheem no suav nrog lub ntsuas qhov ntsuas thiab lub zog tswj, feem ntau yog siv rau hauv cov khoom siv hauv metallurgy, papermaking, film production, dyeing and finishing, weaving, plastics, and wire manufacturing. Nws yog ib qho kev tswj tsis siv neeg uas ua tiav qhov nro tsis tu ncua lossis kev tswj nruj nruj, thiab nws txoj haujlwm tseem ceeb yog ua kom tiav synchronization ntawm yob thiab kev tswj tsis tu ncua ntawm winding thiab unwinding.
