Tsis yog txhua lub tshuab nyob hauv qhov huv, huab cua-tswj lub Hoobkas. Ib txhia siv lawv lub neej sab nraum zoov, ncuav hauv av nkos, blasted nrog xuab zeb, los yog ntog nrog tshuaj. Nyob rau hauv cov cheeb tsam hnyav no, cov txheej txheem cov hlua khi tuaj yeem ua tsis tau sai-qee zaum hauv lub lis piam hloov xyoo.
Tab sis ntawm no yog qhov khoom: nrog cov saw hlau zoo thiab me ntsis ntawm cov tswv yim paub- yuav ua li cas, koj tseem tuaj yeem tau txais kev ntseeg siab, ntev - kev ua tau zoo. Cia peb tham txog dab tsi tshwm sim rau chains hauv cov xwm txheej nyuaj thiab, qhov tseem ceeb tshaj, koj tuaj yeem ua dab tsi txog nws.
irst, Dab tsi ua rau ib puag ncig "Harsh"?
Nws yog ntau tshaj li "me ntsis plua plav." Peb tab tom tham txog cov xwm txheej uas nquag ua haujlwm tawm tsam koj cov khoom siv. Xav txog cov chaw uas koj niaj hnub ua nrog:
· Abrasive grit thiab hmoov av(zoo li kuv lossis chaw txua txiag zeb)
· Dej tsis tu ncua, tshuaj tsuag ntsev, lossis tshuaj(kev ua haujlwm hauv hiav txwv, thaj chaw ntxuav zaub mov)
· Kub kub lossis txias txias(steel mills, kev ua haujlwm sab nraum lub caij ntuj no)
· Kev poob siab hnyav thiab kev co tsis tu ncua(kev tsim kho, hnyav ntoo ua)
· Kev saib xyuas tsis tu ncua(cov chaw taws teeb lossis txuas ntxiv- cov khoom siv ua haujlwm)
Dab tsi tiag mus yuam kev? (Cov Failure Modes)
Thaum cov kab mob sib kis thiab kev ntxhov siab nyob rau hauv ib txoj hlua, ob peb yam tshwj xeeb yuav tshwm sim:
1. Corrosion.Cov dej noo thiab ntsev yog qhov pom tseeb culprits. Lawv noj tam sim ntawd ntawm cov hlau, tsim cov kab xeb uas ua rau cov kev sib txuas thiab cov pins tsis muaj zog. Ib txoj hlua corroded yog ib txoj hlua khi.
2. Abrasive Hnav.Xav txog cov xuab zeb thiab grit li kua sandpaper. Lawv nkag mus rau hauv cov clearances ntawm lubtus pin, bushings, thiabrollers, sib tsoo txhua yam los ntawm sab hauv tawm.
3. Ncua thiab Jamming.Qhov no tshwm sim thaum lubrication tsis ua haujlwm thiab cov khoom paug ntim hauv nruj. Cov saw txuas txuas lus kaw cia, ua rau cov saw hlau caij roughly hla lub sprockets, snap, lossis nres lub tsav.
4. Chain "Strech" (Elongation).Qhov no tsis yog cov hlau tiag stretching; nws hnav ntawm tus pin-thiab- bushing txuas. Raws li cov chaw no hnav, cov saw tau ntev lub cev. Qhov no cuam tshuam lub sijhawm, rhuav tshem qhov nro, thiab zom cov sprockets.
5. qaug zog tawg.Rov ua dua cov khoom hnyav thiab kev ntxhov siab, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig corrosive, tuaj yeem pib tawg me me uas loj hlob mus txog thaum cov khoom tawg.
Yuav Ua Li Cas Rov Qab: Cov kauj ruam ua tau zoo rau lub neej ntev
Koj tuaj yeem hloov tsis tau ib puag ncig, tab sis koj tuaj yeem hloov cov saw thiab seb koj tu nws li cas. Nov yog qhov ua rau muaj qhov sib txawv tiag tiag hauv thaj teb.
1. Xaiv cov khoom tsim nyog rau txoj haujlwm.
Txujcarbon hlauchains yuav xeb ceev ceev hauv qhov chaw ntub dej lossis tshuaj lom neeg. Txhim kho rau astainless hlau sawrau qhov zoo tshaj plaws corrosion kuj, los yog nrhiavzinc -platedlos yognpib tsib xee-platedchains rau tus nqi- txhawb nqa kev tiv thaiv xeb.
2. Mus Hnyav-Lub luag haujlwm.
Rau cov ntawv thov uas muaj kev poob siab lossis qhov nro tsis tu ncua, tus qauv saw yog nyob rau hauv - qhia. Nrhiav chains tshwj xeeb rated raws lihnyav -lub luag haujlwm-lawv muaj daim hlau txuas tuab dua thiab muaj zog pins tsim los rau txim.
3. Xav txog kev kaw los yog tus kheej -Lubricating Chains.
Qhov no yog kev ua si - hloov pauv rau qhov chaw qias neeg.
· kaw cov saw hlausivO-rings lossis X-ringsnruab nrab ntawm qhov sib txuas sab hauv thiab sab nraud. Cov ntsaws ruaj ruaj xauv lub Hoobkas rojhauvthiab khaws abrasive grit thiab noo nootawm. Lawv raug nqi ntau dua pem hauv ntej tab sis nyob ntev dua.
· Tus kheej-lubricating chainsmuajroj-cov roj hmab impregnateduas maj mam tso cov roj nplaum dhau lub sijhawm. Lawv zoo rau cov ntawv thov uas tsis tu ncua phau ntawv lubricating tsis yooj yim sua.
4. Lubrication tseem yog huab tais-Tab sis siv cov khoom zoo.
Hauv cov dej ntub lossis plua plav, cov roj hnyav tuaj yeem nyiam thiab tuav cov grit. Koj feem ntau zoo dua nrog qhov siab - zoo,chain-cov roj tshwj xeebuas nkag mus rau qhov me me clearances thiab resists ntxuav tam sim ntawd. Qhov tseem ceeb yog musrov thov dua ntau zaus; ib txoj saw qhuav yog saw hlau tuag.
5. Khaws qhov muag ntawm kev sib tw thiab kev sib tw.
Ib txoj hlua misaligned hnav tsis sib xws thiab nrawm. Cov slack ntau dhau ua rau whipping thiab shock loads. nruj dhau overloads bearings thiab sprockets. Qhov no tsis yog "teeb thiab tsis nco qab nws" yam - xyuas thiab kho nws tsis tu ncua.
6. Ua Kev Tshawb Fawb Txog Kev Cai.
Nkag mus rau tus cwj pwm ntawm kev kuaj pom sai. Saib rau xeb, hnav tsis sib xws, sib txuas nruj, lossis cov cim ntawm elongation (xws li cov saw caij ntawm cov hniav sprocket). Ob peb feeb ntawm kev tshuaj xyuas tuaj yeem tiv thaiv qhov kev puas tsuaj loj.
