Kev txhais thiab kev cais
Raws li sau tseg hauv Seem 6.3.3.3 ntawm qhov thib tsib tsab ntawm API 541, tus neeg tsis tshua muaj kev yoojyim yog ib qho kev ua yeeb yam los yog lub tshuab hluav taws xob, piv txwv li qhov rotor speed yog nruab nrab ntawm 200 thiab 300 rpm. Ntawm no ceev, cov nyhuv dynamic yog nyob rau theem qis tshaj thiab qhov kev vibration yuav luag tsis yog-existent. Nyob rau hauv lub xeev no, qhov kev nyeem ntawm qhov sib thooj sib txuas yuav tsum muaj kev sib raug zoo nrog rau cov kev kho tsis xws luag tus txhom coj, xws li tawm ntawm kev sib tsoo, qhov sib txawv ntawm cov teeb meem, qhov sib thooj ntawm kev txheeb xyuas thiab kev siv radial, thiab ncej Electromagnetic tsis xws luag hauv cov khoom ntawm khoov lossis ncej.
Cov kauj ruam uas ntsuas tau qis qis tuaj yeem xam muaj: 1. hauv lub tshuab ua ke twb tiav lawm; 2. Muab tso rau ntawm ib lub rooj sib tov sib hloov ntawm V-shaped thaiv ntawm ib nrab ntawm plhaub tus kabmob; lossis 3. rau ib lub tshuab dhos. Lub radial runout ntawm qis ceev rolls los ntawm tsuas yog ob yam: mechanical thiab hluav taws xob.
Mechanical radial runout (MRO) yog qhov sib txawv ntawm qhov cylindrical ntawm cov npluas ntawm qhov ntsuas ntawm lub zoo cylindrical nto thiab cov concentricity nrog cov centerline ntawm cov kabmob. Kev hloov ntawm lub cev muaj xws li: qhov chaw tawm ntawm qhov chaw, qhov chaw ua haujlwm tsis xws luag (xws li kev ua tiav lossis khawb), thiab tsis muaj concentricity ntawm qhov chaw thiab axial center ntawm tus kabmob. MRO yog ib txoj kev ntsuas uas tau siv lub ntsuas qhia hu los yog tus neeg hu xov tooj.
Hluav taws xob radial runout (ERO) ntsuas qhov sib txawv ntawm cov kab xev xaim hluav taws xob thiab cov khoom sib nqus hlau. Cov khoom siv hluav taws xob uas tsis yog tib yam ntawm cov khoom siv hluav taws txuam nrog lub sib nqus thaj chaw ze ntawm lub ntsuas, yog li qhov hloov qhov hluav taws xob hloov, nws ua rau muaj kev hloov hauv cov teeb liab.
Thov nco ntsoov tias yuav kom muaj kev khiav haujlwm ntawm qhov system zoo li qub, cov cheebtsam yuavtsum raug phom. Yog tias cov khoom no tsis phim zoo, qhov ntsuas ntawm qhov vibration yuav tsis raug. Raws li lub neej ua ntej, qhov sib thooj sib tsoo muaj peev xwm siv AISI 4140 steel. Yog tias hom hlau sib txawv, nws yuav cuam tshuam rau qhov ntsuas kev ntsuas. Lwm cov ntaub ntawv tuaj yeem siv tau los txhim kho qhov ntsuas tau yog tias tsim nyog.
