Hauv cov xwm txheej tseem ceeb xws li kev ua cua txias, pneumatic conveying, thiab cov cuab yeej siv hluav taws xob ua kom sov, kev ua haujlwm ruaj khov ntawm siab -ceev thiab siab - lub siab blowers ncaj qha txiav txim siab ntau lawm efficiency thiab khoom siv lub neej. Raws li "lub zog tseem ceeb hub" ntawm cov tshuab tshuab, qhov kev ua tau zoo ntawm cov kabmob yog qhov tseem ceeb tshwj xeeb. Sib sib zog nqus groove pob bearings los ntawm Nyiv NMB (Minebea) tau dhau los ua cov khoom siv rau siab - siab thiab siab - nrawm nrawm hauv ntiaj teb DC BLOWER teb, ua tsaug rau lawv cov txiaj ntsig tseem ceeb ntawm kev ua haujlwm siab, tsis tshua muaj suab nrov, thiab siab - nrawm tsis kam. Lawv cov cuab yeej siv thev naus laus zis thiab cov qauv tsim qauv tuaj yeem ua tau raws li kev ua haujlwm hnyav ntawm cov tshuab tshuab, xws li kev kub ceev, hnyav, thiab kev ua haujlwm tas mus li, txo cov khoom siv tsis ua haujlwm thiab cov nqi kho.
Daim ntawv thov qhov zoo ntawm NMB sib sib zog nqus groove pob bearings nyob rau hauv siab -ceev / siab - siab blowers yog reflected nyob rau hauv peb qhov loj me. Ua ntej,zoo heev siab -ceev stability: Txais NMB cov khoom siv tshwj xeeb MKJ3 alloy thiab precision raceway processing technology, qhov txwv ceev tuaj yeem ua tau raws li qhov siab -kev ua haujlwm ceev ntawm cov tshuab tshuab. Ua ke nrog lub pob zoo sib cuag lub kaum ntse ntse, nws tuaj yeem cuam tshuam cov radial loads zoo thiab zam kev vibration sib txawv thaum lub sijhawm ua haujlwm siab -. Thib ob,zoo heev tsis kam mus rau hnyav ua hauj lwm tej yam kev mob: Lub hom phiaj ntawm qhov siab - qhov kub thiab plua plav ib puag ncig ntawm siab - lub tshuab nqus tsev siab, NMB bearings yog tsim los nrog ob lub sealing qauv los tiv thaiv impurity intrusion thiab roj to. Lawv kuj hloov mus rau siab -kub lubricating media, tswj kev ua haujlwm ruaj khov hauv qhov kub ntawm -20℃txog 120 degree. Thib peb,tseem ceeb tsawg- suab nrov thiab lub zog- txuag cov yam ntxwv: Cia siab rau qis- suab nrov lub cev muaj zog tshwj xeeb tsim (xws li MT series cim), lub suab nrov ntawm kev ua haujlwm tuaj yeem tswj tau qis dua 25dB, ua tau zoo raws li qhov qis- suab nrov ntawm cov khoom siv hauv kev lag luam, thaum txo kev sib txhuam poob thiab txhim kho tag nrho lub zog ntawm cov tshuab tshuab.
Txawm li cas los xij, NMB tus qauv kabmob yog qhov nyuaj, suav nrog ntau cov lej tsis sib xws xws li cov khoom siv, qauv, sib khi, thiab lubrication. Kev xaiv yuav tsum ua tib zoo ua ke nrog lub tshuab ua haujlwm ntawm lub tshuab ua haujlwm, qhov ntev ntawm cov qauv, thiab cov kev xav tau ntawm kev ua haujlwm. Cov hauv qab no txheeb xyuas tus qauv coding logic thiab cov hauv paus ntsiab lus xaiv raws li NMB bearing qauvR-1240KK1B28MTRPOP13LY551saws nyob rau hauv lub siab -pressure blower BA8060 ntawm Shenzhen Tenkai Group, muab cov ntaub ntawv siv tau rau cov ntawv thov kev lag luam.
I. Kev Tshawb Fawb Txog NMB Bearing Model R-1240KK1B28MTRPOP13LY551

Nws tuaj yeem pom los ntawm kev txheeb xyuas cov lej saum toj no tias txhua qhov ntsuas ntawm tus qauv kabmob no yog tsim los rau kev ua haujlwm hnyav ntawm siab - siab thiab siab - nrawm blowers, ua rau nws yog ib qho tseem ceeb rau kev ua haujlwm zoo thiab ruaj khov ntawm BA8060 blower.
II. Lub hauv paus ntsiab lus tseem ceeb rau xaiv NMB Bearings hauv High-Speed/High-Pressure Blowers
Ua ke nrog cov qauv saum toj no, kev xaiv ntawm NMB bearings yuav tsum tsom mus rau lub tshuab ua haujlwm ntawm lub tshuab ua haujlwm thiab tsim kom muaj peb yam -kev xaiv qhov kev xav ntawm "kev ua haujlwm hloov kho - parameter sib piv - kev ua haujlwm rov ua haujlwm". Cov ntsiab cai tshwj xeeb yog raws li nram no:
1. Kev Qhia Txog Kev Ua Haujlwm: Precisely Match Operating Parameters
Rau siab- nrawm nrawm (kev sib hloov ceev Ntau dua lossis sib npaug li 8000r / min), qhov tseem ceeb yuav tsum tau muab rau NMB tuab- hom series (R-/-RF-)) bearings, ua ke nrog qis - suab nrov MT specifications thiab yoj- zoo li tus cagesR ({8}) kev vibration thiab yoj (fri code) Rau siab - siab tshuab (cua siab tshaj lossis sib npaug ntawm 5kPa), tsom rau cov khoom siv zog, nyiam cov khoom siv KK (MKJ3 steel); rau kev ua haujlwm corrosive, DD martensitic stainless hlau qauv tuaj yeem xaiv. Lub caij no, xaiv raws li qhov xav tau kev sib khi - tiv tauj cov roj hmab foob (P code) rau qhov chaw muaj plua plav, steel phaj plua plav npog (Z / K code) rau kev ua haujlwm dav dav, thiab txhim kho labyrinth foob cov qauv rau ib puag ncig hnyav xws li kev lag luam tshuaj. Piv txwv li, nyob rau hauv siab - siab blowers rau tshuaj khib nyiab roj kho, NMB bearings nrog DD cov ntaub ntawv + P tiv thaiv cov ntsaws ruaj ruaj tuaj yeem tiv thaiv ob qho tib si corrosion thiab impurity intrusion.
2. Parameter Matching: nruj me ntsis tswj qhov ntev thiab precision
Txiav txim siab qhov yooj yim bearing qhov ntev raws li lub tshuab raj lub taub hau thiab qhov chaw nruab (piv txwv li, R-1240 sib haum mus rau 12mm puab txoj kab uas hla). Xaiv hom series raws li kev xav tau ntawm cov qauv: nyias-hom (L-/-LF-) lossis ultra-thin type (A{11}}) rau qhov chaw compact, tuab -hom (R-/-RF-} thiab retain series rau hnyav load (RNR-/LNR{18}}) rau axial positioning. Cov qib precision yuav tsum raug xaiv raws li cov khoom yuav tsum tau ua - JIS Class 5 (A5 code) rau precision siab -siab blowers, thiab JIS Class 0 rau kev lag luam scenarios. Clearance thiab roj yuav tsum hloov mus rau kev khiav hauj lwm kub: loj clearance qauv (piv txwv li, P20 series) + siab -kub roj (LY13/LY551) rau siab - kub ua hauj lwm tej yam kev mob (Ntau tshaj los yog sib npaug rau 80 degree), thiab me clearance + low- kub roj (LO18}) rau qis dua (4)℃los yog qis dua ) kom tsis txhob muaj kabmob tsis ua haujlwm los ntawm thermal expansion lossis low-temperature solidification.
3. Kev Ua Haujlwm Tsis Txaus Siab: Kev Tiv Thaiv Kev Nyab Xeeb
Thaum lub sij hawm xaiv, xyuas kom meej lub dynamic rated load ntawm cov kabmob yog ntau tshaj 25% siab tshaj qhov tseeb kev khiav hauj lwm load. Piv txwv li, qhov tseeb radial load ntawm BA8060 blower yog 2kN, thiab dynamic rated load ntawm tus xaiv R-1240KK qauv mus txog 2.8kN, uas tuaj yeem tiv nrog kev hloov pauv sai sai. Meanwhile, optimize lub lubrication scheme - ua ntej-lubricated (LG code) qauv yog nyiam rau high-temperature scenarios kom ntev kev pab cuam lub neej.
