Dab tsi yog qhov sib txawv ntawm couplings?
Hav! Raws li ib tug xa nrog 10 xyoo ntawm kev paub hauvCouplingKev lag luam, Kuv tau txais cov lus nug no los ntawm cov neeg yuav khoom txhua hnub: "Kuv yuav tsum txuas ob motors - Koj yuav tsum xaiv qhov txuas mus li cas?" "Kuv cov khoom siv ua rau kev vibrating, thiab cov txuas yav dhau los ua tsis tiav- Puas muaj cov khoom siv khiav kom haum rau xyoo; qhov tsis ncaj ncees lawm yuav xav tau hloov hauv peb lub hlis xwb. Niaj hnub no kuv yuav taug koj cov txheej txheem tiag tiag ntawm kev xaiv cov kev xaiv rau cov neeg siv khoom, kom nkag siab txog ntau hom thiab yuav ua li cas xaiv qhov zoo tshaj plaws rau koj qhov project.
Kauj ruam 1: 8-kauj ruam qhia kev coj ua rau xaivCouplings (los ntawm cov cai yuav siv)
Ua ntej, hais meej koj txoj haujlwm "txoj haujlwm yuav tsum tau" {{}}} Qhov no yog qhov tseem ceeb los xaiv txoj cai hom.
Ua ntej xaiv sib txuas, teb peb "cov lus nug tseem ceeb" uas txiav txim siab ncaj qha rau kev ua kom pom tseeb rau:
Koj tau sib txuas yog dab tsi?
Nws puas yog lub cev muaj zog rau lub twj tso kua mis? Lossis lub gearbox rau kev siv conveyor? Cov khoom sib txawv muaj cov yam ntxwv sib txawv: Motors tej zaum yuav tsim cov khoom "cuam tshuam" thaum lub sijhawm thaum lub sijhawm thaum lub sijhawm thaum lub sijhawm ua haujlwm. Cov xwm txheej no hais txog kev sib txawv nkaus xwb Couplinghom.
Piv txwv li:Tus Neeg Siv Khoom Xav Tau Txuas Txuas "Lub Cev Muaj Zog + Centrifugal twj tso kua mis." Lub twj tso kua mis cov ncej ua tau nthuav dav radial runout (kwv yees 0.1mm) thaum lub sijhawm ua haujlwm. Kuv pom zoo ib qho "txuas tshiab" (muaj peev xwm them nyiaj rau kev ua tsis yog). Tab sis rau cov neeg siv khoom b sib txuas "lub cev muaj zog + precision tshuab tool spindle," uas yuav tsum muaj xoom, Kuv pom zoo ib qho "Coupd sib txuas." Yog tias kuv tau ua yuam kev xaiv ib qho kev txuas ntxiv rau cov qhua tuaj noj mov b, lub tshuab hloov chaw ntawm 0.001mm rau 0.01 hli, rov ua nws tsis siv tau.
Dab tsi "dag yuam" yuav tsum kis tau?
Tshwj xeeb, "torque" thiab "tig ceev" kev sib txuas yuav tsum tau tiv thaiv tau. Piv txwv li, lub cev muaj zog me me (torque 5 txhiab, ceev 1500 rpm) tsuas yog yuav tsum tau yas "{hom conving"; Tab sis rau ib qho hnyav {{{{} Duty} Duty} Dute {, koj yuav tsum xaiv lub cim "nrawm dua," nyiam dua tshiab ua los ntawm cov hlau cam khwb cia. Ib tus neeg siv khoom ib zaug xaiv rau tus pheej yig dua kev txuas rau lawv cov crusher, tsuas yog rau nws tawg tom qab peb hnub. Qhov no tshwm sim cov kab ntau lawm downtime thiab xaus rau kev them nqi ntau dua.
Koj puas muaj "precision" yuav tsum tau?
Rau cov khoom siv zoo li ntim tshuab lossis luam tawm, qhov twg "radial runout" ib qho kev hloov pauv yuav tsum tsis pub tshaj 0.02mm, xaiv ib qho "diaphragm txuas mus rau" lossis " Txog kev sib txuas xws li conveyor siv tawv, qhov twg kev sib txawv hauv 0.1mm yog tau, "paj {{} Daim ntawv hloov pauv yooj yim". Cov kev ntsuas siab dua qhov yuav tsum tau xaiv cov kev xaiv ntawm kev sib txuas hom thiab coj tus nqi nce ntxiv.
Kauj ruam 2: Ntsuas "cov ntaub ntawv" {-} Cov khoom sib txawv txiav txim siab aCoupling's' tus yam ntxwv '
Ib coupling cov khoom yog zoo li nws tus "Txoj Cai," cuam tshuam nws qhov kub tsis kam, thiab corrosion tsis kam. Plaub pawg txhua yam muaj qhov sib txawv:
Stainless hlau 304 cov neeg sib txawv tseem muaj cov khoom siv corrosion, ua rau lawv tseem ceeb rau cov khoom siv hiav txwv
Stainless hlau 304 cov khoom siv kuj, ua rau nws tseem ceeb rau cov khoom siv hiav txwv uas yog cov twj tso kua mis {} Tom qab tsib xyoos, nws qhia tsis muaj cov cim qhia xeb.
Cam Khwb Cia Hlau Khoom (Pob Cam Khwb Cia Hlau, Zas Hlau)
Pheej yig dua cov hlau nrog cov qauv sib luag, tab sis nkig (cuam tshuam rau kev cuam tshuam). Haum rau nyob ruaj ruaj, tsis -}} pa cov kev sib txuas nrog cov kiv cua qis, nrog rau lub neej ntev li 4 - 6 xyoo. Tam sim no nce tsawg, raws li feem ntau cov neeg siv khoom xaiv rau cov hlau siv tau zoo los yog aluminium alloys.
Kauj ruam 3: Pinpots lub "Qhov ntev" -} tsis muaj qhov kawg nws tsuas yog tsis muaj teeb meem nws yuav tsis muaj dab tsi zoo npaum li cas.
Xaiv Ib Coupling yog zoo li kev yuav khaub ncaws - nws yuav tsum haum txig. Ob qhov tseem ceeb tshaj plaws teeb meem:
Nchuab diam (beg txoj kab)
Ob qho kawg ntawm kev sib txuas yuav tsum haum rau cov khoom siv hauv tes. Lub rege ntawm txoj kab yuav tsum tau qhia meej qhov Ncej hla, nrog rau kev thev taus tsis tshaj 0.02 hli. Yog tias koj yuav ib qho 21mm Coupling, nws yuav wobble thaum lub sijhawm teeb tsa thiab ua rau kev co thaum lub sijhawm ua haujlwm.
Ntev (tag nrho ntev):
Qhov kawg ntev yuav tsum tau nyiaj rau "tshem tawm cov khoom siv" ntawm cov khoom siv.
Tsis tas li ntawd nco ntsoov "Hub ntev" (ib feem ntawm kev sib txuas haum rau ntawm tus ncej), uas yuav tsum tsis txhob luv dua.
Kauj Ruam 4: Kos rau "Nto Ua tiav" -}} Tsis Yuav Tsum Tau Rau Txhua TusCouplings, tab sis tseem ceeb nyob rau hauv cov ntawv thov tseem ceeb
Ntau tus neeg muas zaub saib xyuas saum npoo ua tiav, tsis tau muaj teeb meem ntau dua li qhov koj xav hauv cov xwm txheej no:
High - Precision Daim Ntawv Thov: Cov cuab yeej ntsuas tshuab, Servo Motors:Couplings yuav tsum ua tiav qhov chaw ua tiav ntawm Ra0.8μm (mloog zoo li daim iav {{du rau qhov kov). Kev ua tsis zoo (ra3.2μm +) ua rau cov sab saum toj profusions uas hloov chaw ntawm kev sib tsoo thaum ua haujlwm. Feem ntau xaiv "Diaphragm Couplings" lossis "Cov Hluav Taws Xob Hlwb" rau cov ntawv thov no, ob qho tib si dhau los sib tsoo ua ntej cov zaub mov xa tuaj ua ntej ua zaub mov xa tuaj.
Corrosion -} prone scenarios:
Cov cuab yeej ua zaub mov (xav tau cov muab yaug) thiab tshuaj ntau. Couplings nrog cov npoo siab tiav (RA 1.6μμm) Tiv Thaiv Cov Ncua Quaj, Tiv Thaiv Kev Ua Phem, thiab Kev Tu Kom Tu. Kev ua tiav tsis zoo pub rau cov khoom paug rau Lodge nyob rau hauv Crevices, cov ntaub ntawv corroding nyob rau lub sijhawm.
Txuj ci:
Nto ua tiav RA 3.2μm surices. Tsis tas yuav tsum tau ua kom ntau dua smoothness, uas yuav ua kom cov nqi los ntawm 20% -30%. Piv txwv li, thaum ib tus neeg siv khoom xaiv ib coupling rau kev siv conveyor, Kuv pom zoo kom aluminium qauv nrog RA 3.8μm thiab ua yeeb yam zoo kawg nkaus.
Kauj ruam 5: Xav txog "kev teeb tsa" kev sib xyaw thiab kev sib raug zoo "-} Tsis txhob cia covCouplingUa "kev teeb tsa ua npau suav phem"
Thaum xaiv ib coupling, xav txog "Yuav ua li cas nws yuav raug ntsia" thiab "txawm tias nws yuav sib xws nrog lwm cov khoom siv" kom tsis txhob muaj teeb meem:
Txoj kev teeb tsa:
Cov kev xaiv sib txawv muaj xws li "qhov tseem ceeb sib txuas" (nyab xeeb los ntawm cov ntsia hlau txuas rau ntawm tus ncej), thiab "kev ruaj ntseg nrog tus yuam sij) (nyab xeeb los ntawm lub siab ntawm lub tes tsho expansion).
For small equipment (torque ≤ 50 N·m), set screws suffice for easy installation. Medium equipment (50–500 N·m) requires keyed connections for stability. Heavy equipment (>500 txhiab tus) yuav tsum siv lub tes tsho nthuav dav los tiv thaiv kom tsis txhob raug rho tawm.
Kev sib haum:
Xyuas kom meej lub coupling tsis cuam tshuam nrog lwm cov cuab yeej cuab tam. Yog tias cov roj kab lossis xaim puag ncig cov khoom siv, lub coupling lub taub plawv yuav tsum tsis txhob muaj ntau dhau los tiv thaiv kev tiv tauj thaum lub sijhawm ua haujlwm. Rau cov cuab yeej siv tas los yuav tsum nquag disassembly, xaiv ib "splitembbable) {2} Ib tus neeg yuav khoom tau siv lub cev muaj zog rau txhua txoj kev txij nkawm. Tom qab hloov mus rau kev sib cais sib cais, lub sijhawm txij nkawm tau poob txij li 2 teev mus rau 20 feeb.
Kauj Ruam 6: Haum rau "ib puag ncig cov kev mob" {-}} cov chaw hnyav tau thov hom yog
Ib puag ncig yog tusCoupling"S" ntsiag to killer. " Xaiv hom tsis ncaj yuav tau halvows nws lifespan. Plaub qhov chaw hnyav ib txwm muaj xws li:
High-temperature environments (>150 degree): Cov khoom siv kom qhuav, cov kiv cua boiler. Tsis txhob muaj yas lossis roj hmab txuas (lawv yaj). Opt rau "Hlau Diaphragm Couplings" (steel lossis aluminium alloy) muaj peev xwm nrog nrog kev kub siab ntau dua li 300 degree.
Plua plav ib puag ncig:
Rau cov chaw tsuas lossis cov nroj tsuag xis mas, xaiv "couplings nrog kev tiv thaiv npog" los tiv thaiv cov hmoov av los ntawm kev nkag mus thiab hnav cov khoom sab hauv. Qhib -} Typ Coup hmoov av hauv qhov khoob, ua rau cov neeg siv mining qhib kev xav tau txhua hli; Tom qab ntxiv cov zov me nyuam, kev ntxuav tu yog tsuas yog rau txhua rau lub hlis.
High - chaw kev tsheb: rau cov crushers, vibrating cov ntxaij vab tshaus, thiab lwm yam "Cajlible." Lawv lub elastomers sab hauv (roj hmab, polyurethane) nqus kev vibrations, tiv thaiv cov tshuab hluav taws xob thiab khoom siv. Yog tias siv cov roj tswm ciab, vibrations hloov ncaj qha rau lub cev muaj zog, ua rau muaj lub cev muaj zog poob rau hauv rau lub hlis. Ib tus neeg yuav khoom muaj kev paub txog lub cev muaj zog hloov pauv txhua peb lub hlis nrog kev hloov pauv ntawm cov crusher, tab sis tom qab hloov mus rau kev hloov pauv yooj yim, hloov tau tsuas yog txhua xyoo.
Kauj Ruam 7: Txheeb xyuas "Zoo thiab Ntawv Pov Thawj" -}}}}} iller cov khoom lag luam "kom tiv thaiv yav tom ntej cov teeb meem.
Ntau tus neeg muas zaub xaiv rau pheej yig duaCouplingS los ntawm cov teeb meem me me, tsuas yog ntsib teeb meem sai tom qab siv.
Cov Ntawv Pov Thawj Khoom Siv:Cov npe nrov tsim cov ntawv pov thawj muab cov ntaub ntawv pov thawj ua pov thawj tseeb, tsis yog "hloov cov ntaub ntawv qis dua." Ib tus neeg yuav khoom cuav 304 stainless hlau couplings uas xeb tsis pub dhau rau lub hlis. Tom qab thov peb cov ntaub ntawv tshaj tawm, lawv paub tseeb tias cov khoom ua ntej tau cuav.
Ntawv pov thawj:Rau cov cuab yeej siv export, xaiv couplings nrog CE lossis UL daim ntawv pov thawj. Rau cov khoom siv tshwj xeeb hauv tsev, ua kom raws li cov qauv GB. Txoj cai tswj hwm tsis tiav yuav ua tsis tau raws li kev nyab xeeb cov cai, nce kev phom sij ntau.
Kauj Ruam 8: Tswj "nqi" {- tus nqi siab dua tsis txhais tau tias zoo dua; Nqi - ua tau zoo reigns zoo tshaj plaws
Kauj ruam kawg yog xam cov nqi, tab sis tsom rau "tag nrho tus nqi" es tsis yog tus nqi yuav khoom:
Luv - tsis siv (1-2 xyoo):Rau cov kab ntau yam ib ntus lossis cov khoom siv me me, xaiv yas lossis cov qauv txhuas alloyCouplings them nqi kaum rau ntau pua nyiaj ib zaug. Txaus ua tau zoo yog qhov tseem ceeb - Tsis tas yuav xaiv cov kev xaiv kim.
Ntev - tsis siv (3+} xyoo):Rau cov kab ntau lawm lossis cov khoom siv hnyav, ua ntej ua ntej hlau lossis stainless hlau couplings. Txawm hais tias muaj ib tus zuj zus (dhau ib txhiab daus las), lawv ncua lub neej txo ntev - lub sij hawm tu cov nqi.
Ntev - tsis siv (3+} xyoo):Rau cov kab ntau lawm lossis cov khoom siv hnyav, ua ntej zoo dua tus nqi.
Xaus: Qhov tseem ceeb ntawm Coupling xaiv - "Xaiv raws li cov kev xav tau, tsis dig muag tom qab txuas ntxiv"
XaivCouplings tsis nyuaj heev. Lub ntsiab cai tseem ceeb yog "nkag siab koj cov kev xav tau ua ntej, tom qab ntawd phim hom rau daim ntawv thov":
Rau cov khoom siv ntsuas ua ntej xav tau cov khoom muaj siab thiab xoom offset, xaiv "membrane couplings" lossis "Coulid couplings" los ntawm cov hlau tsis zoo lossis hlau.
Rau hnyav {{{0} duasts} cov khoom siv siab thauj khoom muaj peev xwm thiab "lub hnub qub {} hom hlau yooj yim txuas" ua los ntawm 45 steel lossis steel hlau.
Nyob rau hauv cov chaw hnyav (kev kub siab, plua plav), ua ntej hlau txuas nrog cov nta hlau nrog kev xaiv yas lossis roj hmab.
