Yog tias koj lub crusher vibrating nyuaj dua li niaj zaus, khiav kub dua, lossis nti tawm cov khoom loj, lub rotor feem ntau yog thawj qhov chaw saib - thiab feem ntau qhov chaw kawg cov tswv xav kuaj. Cov pab pawg tu feem ntau kho cov teeb meem rotor raws li "kho nws thiab txav mus rau" teeb meem. Tab sis nyob rau hauv kev xyaum, ib tug loj feem ntawm recurring faults ib tug rov qab mus rau ib tug hauv paus ntsiab lus: lub hloov rotor los yog rauj teem ntsia tsis tau raws li qhov tseeb spec nyob rau hauv thawj qhov chaw.
Phau ntawv qhia no taug kev los ntawm cov tsos mob ntawm rotor tsis ua hauj lwm feem ntau, yuav ua li cas kuaj xyuas lawv, thiab - ib yam li qhov tseem ceeb - yuav ua li cas paub thaum kho tsis yog cov lus teb raug lawm thiab kev hloov crusher rotor yog tus nqi ntau dua - txoj hauv kev zoo.
Kev vibration tsis zoo thiab Rotor Imbalance
Kev vibration yog cov neeg ua haujlwm tsis txaus siab tshaj plaws tshaj tawm, thiab nws yuav luag ib txwm khi rau rotor tsis txaus. Lub crusher rotor spin ntawm kev kub ceev, yog li txawm tias qhov sib txawv me me ntawm hammers lossis tshuab tuav tsim muaj zog centrifugal. Qhov no qhia tau hais tias:
Kev vibration uas nce raws li kev ceev tsim
Tsis sib xws hnav cov qauv ntawm rauj lossis tshuab tuav
Cov kabmob ntxov ntxov hnav ntawm ib sab ntawm lub rotor
Kev kuaj mob:Kos rauj lossis tshuab qhov hnyav hauv cov khub sib tw - feem ntau OEM specs tso cai tsis pub ntau tshaj 0.5 kg qhov sib txawv ntawm cov khoom sib txuas ntawm sab nraud ntawm lub rotor. Yog hais tias cov hammers tau hloov ib tus zuj zus es tsis yog nyob rau hauv symmetrical sets, imbalance yuav luag guaranteed.
Kho vs. hloov qhov pib:Yog tias kev vibration txuas ntxiv tom qab rov- ntsuas thiab hloov rauj, thiab lub rotor lub cev nws tus kheej pom pom kev deformation, vuam kho ntawm lub rotor qaug zog tsis tshua muaj nyob rau hauv kev cuam tshuam tsis tu ncua. Thaum lub sijhawm ntawd, kev hloov pauv muaj kev nyab xeeb dua thiab pheej yig dua li qhov rov qab kaw dua.
Bearing overheating los yog hnav ntxov ntxov
Cov kabmob tsis ua haujlwm tsis tshua muaj qhov kev ua txhaum ntawm ib leeg - nws feem ntau yog cov tsos mob ntawm cov teeb meem rotor. Feem ntau ua rau muaj xws li:
Lub lubrication tsis txaus los yog tsis muaj paug
Rotor imbalance hloov lateral load mus rau cov kabmob
Misalignment ntawm lub rotor ncej thiab vaj tse
Kev kuaj mob:Lub suab qhuav, sib tsoo thaum lub sijhawm ua haujlwm feem ntau qhia tias lubrication tshaib plab. Lub suab tsis txuas ntxiv feem ntau txhais tau hais tias kev sib tw kev puas tsuaj los ntawm cov khib nyiab nkag. Disassemble thiab xyuas pitting, discoloration ntawm tshav kub, los yog ntxhib rotation thaum spun los ntawm tes.
Dab tsi feem ntau nco:Yog hais tias ib tug bearing tsis ua hauj lwm nyob rau tib lub rotor txawm tias tom qab relubrication thiab huv si installation, cov kabmob lub tog zaum kam rau ntawm lub rotor ncej nws tus kheej tej zaum yuav tawm ntawm spec - ib qho teeb meem uas tsis zoo machined hloov rotors uas tsis phim OEM dimensional tolerances.
Rotor dabtsi yog khoov los yog tawg
Qhov no yog qeb tsis ua hauj lwm loj tshaj plaws thiab qhov tseeb tshaj plaws uas qhov kev hloov pauv tsis yog -xav tau. Ua rau muaj xws li:
Oversized pub khoom tshaj lub crusher tus nqi peev
Tramp hlau los yog uncrushable khoom nkag mus rau hauv lub chamber
Ntev - lub sij hawm qaug zog los ntawm kev poob siab dua
Kev kuaj mob:Kev soj ntsuam pom kev tawg, tshwj xeeb tshaj yog nyob ze rau rauj pin qhov thiab ncej-rau-disc welds, qhov twg muaj kev ntxhov siab. Txhua qhov tawg ntev dua li ob peb millimeters ze ntawm qhov chaw thauj khoom - bearing weld point yog qhov kev pheej hmoo ntawm kev nyab xeeb, tsis yog teeb meem tshuaj pleev ib ce.
Lub rotor khoov los yog tawg yuav tsum tsis txhob welded thiab rov qab mus rau qhov kev pab cuam yam tsis muaj tag nrho cov dynamic re- sib npaug thiab, qhov zoo tshaj, tsis yog - kuaj kev puas tsuaj. Hauv peb qhov kev soj ntsuam xyuas cov rotors uas raug xa rov qab los ntawm cov neeg siv khoom txawv teb chaws, cov kab nrib pleb uas tshwm sim me me ntawm qhov chaw feem ntau txuas ntxiv mus rau hauv cov qauv disc - uas yog vim li cas tawg - ntev eyeballing ib leeg tsis yog qhov kev xeem dhau / tsis ua tiav.
Loose or Fallen Hammers
Loose hammers feem ntau yog kev saib xyuas kev saib xyuas ntau dua li qhov tsim tsis zoo, tab sis sab laug tsis kho lawv nce nrawm rau hauv rotor kev puas tsuaj.
Thauj tog rau nkoj bolts loosen nyob rau hauv tas li cuam tshuam thiab kev co
Pin shafts hnav los yog khoov, cia rauj ua si
Ib qho xoob rauj hloov tag nrho rotor qhov sib npaug
Kho:Tighten thauj tog rau nkoj bolts ntawm lub sijhawm teem sijhawm es tsis yog rov ua haujlwm. Hloov pauv tus pin shafts tam sim ntawd - ib tug bent pin ncej feem ntau yog lub cim ceeb toom ntxov uas ua ntej ib tug rauj los xoob nkaus.
Txo cov zis lossis cov khoom pov tseg ntau dhau
Thaum cov khoom lag luam loj hlob tuaj lossis nce zuj zus zuj zus, nws yog kev ntxias kom liam rau qhov screen lossis pub tus nqi. Tab sis qhov xwm txheej rotor feem ntau yog qhov ua txhaum tiag tiag:
Tsis sib xws rauj / tshuab tshuab hnav hloov pauv cuam tshuam geometry
Txoj siv slippage txo qhov tseeb rotor ceev hauv qab rated RPM
Cov khoom tsim ntawm rotor thiab liner txo qhov chaw crushing zoo
Kev kuaj mob:Ntsuas qhov tseeb rotor RPM tiv thaiv qhov nrawm nrawm - qhov sib txawv ntawm no feem ntau taw qhia rau txoj siv tawv lossis tsav teeb meem ntau dua li lub rotor nws tus kheej. Yog tias RPM yog qhov tseeb tab sis cov txiaj ntsig zoo tseem poob qis, tshuaj xyuas rauj hnav tsis zoo; hnav dhau li ntawm 30-40% ntawm thawj qhov profile feem ntau lav hloov dua li siv txuas ntxiv.
Lub hauv paus ua rau cov neeg sib tw tsis tham txog: Rotor Sourcing
Nov yog qhov kev daws teeb meem ntau yam hla dhau tag nrho: ntau qhov "rov ua dua" rotor faults tsis yog qhov rov ua tsis tiav tiag tiag - lawv yog qhov tsis ua haujlwm zoo ib yam ntxiv vim qhov hloov pauv tsis yog thawj zaug.
Qhov no feem ntau tshwm sim hauv ob qhov xwm txheej:
1. Thawj qhov yog txiav tawm lossis nyuaj rau qhov chaw.Cov qub crushers, los yog cov cav tov khiav ntawm cov hom uas muaj kev txhawb nqa hauv cheeb tsam, feem ntau tsis tuaj yeem tau txais kev sib tw OEM. Cov neeg yuav khoom xaus nrog kev hloov pauv dav dav uas nyob ze tab sis tsis zoo ib yam - uas tom qab ntawd ua rau lub rooj zaum tsis sib haum, tsis sib xws, lossis hnav ntxov ntxov, txawm tias qhov kev teeb tsa tau ua tiav lawm.
2. Cov khoom siv tshwj xeeb tsis phim qhov kev ua haujlwm tiag tiag.Lub rotor ua rau tus qauv hnav tsis zoo yuav tsis tuav hauv siab - cuam tshuam lossis siab - daim ntawv thov dej noo. Yog tias koj lub crusher ua haujlwm txawv txav los yog cov khoom ntub dej, cov qauv hloov pauv feem ntau ua tsis tau sai dua li qhov xav tau - tsis yog vim kev saib xyuas tsis zoo, tab sis vim tias qib khoom tsis haum rau txoj haujlwm.
