Cov txheej txheem hloov cov roj foob hauv lub tshuab excavator muaj ob peb kauj ruam tseem ceeb

Cov txheej txheem hloov rau ib qhoroj foobnyob rau hauv ib qho excavator muaj ob peb kauj ruam tseem ceeb, ua kom muaj kev ua kom zoo kom muaj kev ncaj ncees thiab kev ua haujlwm ntawm lub tshuab. Nov yog phau ntawv qhia ntxaws:

Kev npaj

1. Sau cov khoom siv thiab cov cuab yeej tsim nyog:
   • Roj foob (s) tshiab
   • Cov cuab yeej xws li wrenches, screwdrivers, hammers, socket sets, thiab tejzaum nws cov cuab yeej tshwj xeeb xws li roj foob pullers lossis installers.
   • Cov khoom siv ntxuav (piv txwv li, rags, degreaser)
   • Lubricant (rau roj foob installation)
2. Kaw thiab txias Excavator:
   • Tua lub cav thiab tso cai rau nws kom txias kom tsis txhob kub hnyiab lossis hnav nrawm thaum lub sijhawm disassembly.
3. Ntxuav thaj chaw ua haujlwm:
   • Xyuas kom lub cheeb tsam nyob ib ncig ntawm cov roj foob yog huv si thiab tsis muaj av, plua plav, los yog cov khib nyiab kom tsis txhob muaj kab mob ntawm cov khoom sab hauv.

Disassembly

1. Tshem tawm cov Cheebtsam Surrounding:
   • Nyob ntawm qhov chaw ntawm cov roj foob, koj yuav tsum tau tshem tawm qhov chaw nyob ib sab lossis npog kom nkag mus rau nws. Piv txwv li, yog tias hloov lub crankshaft roj foob, koj yuav tsum tau tshem tawm cov flywheel lossis kis tau tus mob.
2. Ntsuas thiab Mark:
   • Siv lub caliper lossis ntsuas ntsuas los ntsuas cov roj foob qhov ntev (sab hauv thiab sab nraud) yog tias tsim nyog rau kev xaiv qhov raug hloov.
   • Kos ib qho kev sib hloov (xws li lub flywheel) kom tsim nyog reassembly tom qab.
3. Tshem Tawm Cov Roj Roj Seal:
   • Siv cov cuab yeej tsim nyog (piv txwv li, roj foob rub) kom ua tib zoo tshem cov roj foob qub ntawm nws lub rooj. Tsis txhob ua kom puas qhov chaw nyob ib puag ncig.

Ntxuav thiab tshuaj xyuas

1. Ntxuav Cov Roj Seal Housing:
   • Ua tib zoo ntxuav thaj chaw uas cov roj foob zaum, tshem tawm cov roj seem, roj, lossis cov khib nyiab.
2. Tshawb xyuas Surfaces:
   • Tshawb xyuas cov cim ntawm kev hnav, kev puas tsuaj, lossis kev sib tw ntawm qhov chaw sib tw. Kho lossis hloov cov khoom puas raws li xav tau.

Kev teeb tsa

1. Siv Lubricant:
   • Maj mam muab cov roj foob tshiab nrog cov roj nplua nyeem tsim nyog los pab txhim kho thiab txo kev sib txhuam.
2. Nruab Cov Roj Seal Tshiab:
   • Ua tib zoo nias lub foob roj tshiab rau hauv nws lub rooj, kom nws lub rooj zaum sib npaug thiab tsis muaj qhov sib tw. Siv rauj thiab xuas nrig ntaus lossis ib lub cuab yeej tshwj xeeb yog tias tsim nyog.
3. Tshawb xyuas Alignment thiab Tightness:
   • Xyuas kom cov roj foob tau zoo sib xws thiab nruj nruj. Kho raws li qhov xav tau los tiv thaiv kev xau.

Reassembly thiab kuaj

1. Reassemble Surrounding Cheebtsam:
   • Rov qab cov txheej txheem disassembly, rov nruab tag nrho cov khoom tshem tawm hauv lawv qhov chaw qub thiab ua kom nruj rau qhov ntsuas qhov tseem ceeb.
2. Sau thiab txheeb xyuas cov kua theem:
   • Tshem tawm cov kua dej uas tau ntws tawm thaum lub sijhawm ua haujlwm (piv txwv li, cov roj cav).
3. Test lub Excavator:
   • Pib lub cav thiab tso cai rau nws khiav rau ob peb feeb, kuaj xyuas cov pa xau nyob ib puag ncig cov roj foob tshiab.
   • Ua ib qho kev sim ua haujlwm zoo ntawm excavator kom paub meej tias txhua yam ua haujlwm raug.

Cov lus qhia ntxiv

• Xa mus rau Phau Ntawv Qhia: Nco ntsoov sab laj tus excavator tus tswv phau ntawv lossis phau ntawv qhia kev pabcuam rau cov lus qhia tshwj xeeb thiab cov lus qhia tshwj xeeb.
• Siv Cov Cuab Yeej Tsim Nyog: Kev nqis peev hauv cov cuab yeej zoo thiab cov cuab yeej tshwj xeeb kom ua haujlwm yooj yim dua thiab txo qhov kev pheej hmoo ntawm kev puas tsuaj.
• Kev Nyab Xeeb Ua Ntej: Hnav cov iav kev nyab xeeb tsim nyog (xws li, tsom iav kev nyab xeeb, hnab looj tes) thiab ua raws li cov txheej txheem kev nyab xeeb kom raug thaum tag nrho cov txheej txheem.

Los ntawm kev ua raws li cov kauj ruam no ua tib zoo, koj tuaj yeem ua tiav cov roj foob hauv lub tshuab excavator, pab tswj nws txoj kev ntseeg tau thiab kev ua tau zoo dhau sijhawm.
