Rotary unions, los yog cov pob qij txha teb, yog cov khoom tseem ceeb rau kev hloov cov kua dej (xws li dej, chav dej, roj hydraulic, lossis roj thermal) ntawm cov khoom siv nyob ruaj ruaj thiab cov tshuab tig. Feem ntau nyob rau hauv daim ntawv sau npe los ntawm kev luam ntawv xovxwm thiab ntawv tshuab rau cov tshuab ziab khaub ncaws thiab CNC machining chaw, lawv txoj haujlwm txhim khu kev qha yog qhov tseem ceeb rau kev tsim khoom. Kev tu thiab tu kom zoo tsis yog cov txheej txheem pom zoo xwb; lawv yog cov kev coj ua tseem ceeb uas txiav txim siab ncaj qha rau lub neej kev pab cuam, tiv thaiv kev puas tsuaj loj, thiab tsis txhob raug them nyiaj poob haujlwm.
Lub Hauv Paus: Kev Tu Kom Huv Si Thaum Ua Haujlwm
Tsis tu ncua, ceev faj tu kom tsis txhob muaj cov khoom seem thiab cov khoom seem uas ua rau abrasive hnav thiab txhaws. Cov txheej txheem yuav tsum yog txheej txheem thiab tailored rau lub conveyed nruab nrab.
Ua ntej- Ntxuav & Disassembly: Ib txwm cais qhov sib koom ua ke los ntawm qhov chaw siab thiab qhov kub thiab txias thiab cia nws txias tag. Ua raws li cov neeg tsim khoom siv phau ntawv, disassemble lub tsev kom zoo. Soak cov khoom tseem ceeb hauv cov kuab tshuaj uas tsim nyog - piv txwv li, kerosene -raws li lub tshuab nqus tsev rau cov roj seem lossis cov tshuaj descaling rau cov pob zeb hauv av los ntawm dej. Ultrasonic tu tso tsheb hlau luam muab cov txiaj ntsig zoo tshaj plaws rau kev sib txuam hauv cov lus.
Cheebtsam-Tshuaj tshwj xeeb: Cov chaw sib khi tseem ceeb ntawm lub rotor thiab stator yuav tsum tau ua kom zoo, tsis yog{1}} abrasive tu. Siv lint- cov ntaub dawb los yog txhuam txhuam nrog cov kuab tshuaj. Qhov tseem ceeb, tsis txhob siv cov txhuam hlau hnyav lossis cov ntaub nplaum uas tuaj yeem ua rau lub ntsej muag tawv tawv, tsim kom muaj txoj hauv kev. Rau cov pob bearing sib dhos, ntxuav nrog cov kuab tshuaj huv kom txog thaum nws ua kom pom tseeb, tom qab ntawd relubricate tam sim ntawd nrog rau qhov siab tshaj - kub roj los tiv thaiv corrosion.
Proactive Maintenance: Inspection & Prevention
Teem sijhawm txij nkawm, raws li cov sijhawm ua haujlwm lossis cov voj voog, yog qhov tseem ceeb. Txhua qhov disassembly yog lub sijhawm rau kev tshuaj xyuas thiab kev tiv thaiv.
Kev Tshuaj Xyuas Foob: Tshawb xyuas tag nrho cov txheej txheem cov ntsaws ruaj ruaj thiab cov O- cov nplhaib thib ob rau qhia- cov cim qhia txog kev hnav: tawg, tiaj tiaj, poob ntawm elasticity, los yog cov txheej txheem ntau dhau. Hloov lawv ua ib txheej siv cov chaw tsim khoom- cov khoom siv pom zoo; sib tov cov qub thiab tshiab cov ntsaws ruaj ruaj yuav ua rau tsis ua hauj lwm ntxov ntxov.
Bearing & Surface Check: Tshawb xyuas cov kabmob kom muaj kev sib hloov thiab kev ua si. Tshawb xyuas lub ntsej muag tseem ceeb ntawm lub ntsej muag (qhov "daim iav" qhov chaw) rau grooves, pitting, lossis corrosion. Qee qhov kev tsis zoo me me tuaj yeem ua rau polished nrog ultra-paste zoo, tab sis kev puas tsuaj tob yuav tsum tau hloov cov khoom.
Reassembly raws tu qauv: Reassemble nrog scrupulous cleanliness. Lubricate tag nrho cov ntsaws ruaj ruaj thiab O- nplhaib me ntsis nrog cov kua nruab nrab uas lawv yuav ntsib (los yog cov roj silicone sib xyaw) kom tsis txhob qhuav - pib puas. Ua raws nraim li cov chaw tsim khoom tau teev tseg torque sequences thiab qhov tseem ceeb rau vaj tse bolts. Tshaj -torquing tuaj yeem ua rau cov tsev nyob thiab cuam tshuam cov kev sib khi zoo.
Common Pitfalls & Kev coj ua zoo tshaj plaws
Feem ntau cov kev saib xyuas yuam kev yog los ntawm shortcuts. Siv cov kua dej tsis raug lossis tsis muaj paug, tsis quav ntsej me ntsis xau ("weepage"), lossis rov siv dua cov ntsaws ruaj ruaj uas pom tau tias yog kev lag luam cuav uas ua rau muaj kev ua tsis tiav loj. Rau cov pob qij txha nyuaj lossis cov ntawv thov tseem ceeb, kev koom tes nrog cov chaw tsim khoom lossis cov kws tshaj lij uas tau lees paub rau lub sijhawm hloov kho kom ntseeg tau tias kev ua haujlwm zoo.
Thaum kawg, kev qhuab ntuas tu thiab tu cov txheej txheem hloov pauv cov kev sib koom ua ke los ntawm cov khoom siv uas siv tau los ua cov khoom muaj nqis, ntev -. Los ntawm kev nqis peev hauv kev saib xyuas, kev ua haujlwm ruaj ntseg txuas ntxiv mus, tiv thaiv cov khoom siv hauv qab los ntawm kev sib kis, thiab ua tiav tus nqi qis tshaj ntawm cov tswv cuab rau lawv cov kev hloov pauv tseem ceeb.
