1. Tom qab kev ua haujlwm ntawm lub tshuab ziab khaub ncaws ua tiav, lub ntsuas kub yuav tsum tau hais kom kho qhov chaw ntawm 0 degrees kom txo qis kev pib ua haujlwm tsis zoo thiab ua kom lub neej ua haujlwm ntev ntawm solenoid valve.
2. Qhov kub thiab txias ntawm lub tshuab ziab khaub ncaws yuav tsum tau teem caij raws li qhov ziab ntawm cov khoom kom qhuav, kom tsis txhob shrinkage ntawm cov khoom kom qhuav.
3. Ua ntej txhua qhov kev siv lub tshuab ziab khaub ncaws, lub tshuab lim paj rwb yuav tsum tau ntxuav. Yog tias lub lim raug thaiv vim kev tu tsis raug, huab cua ntim yuav txo qis, qhov ziab nrawm yuav qeeb heev, thiab cov nyhuv ziab yuav tsis zoo. , Nws yuav nkim ntau yam kev pab.
4. Yog tias tsuas yog ib feem ntawm cov khaub ncaws uas tau qhuav qhuav yuav tsum tau qhuav, cov khoom seem ntawm cov khoom ziab yuav tsum tau volatilized tag nrho ua ntej muab tso rau hauv lub tshuab ziab khaub ncaws.
5. Nyob rau hauv ib txwm siv, cov pa roj carbon hmoov (dub) ntawm lub qhov cub roj yuav tsum tau muab ntxuav tawm txhua lub lim tiam kom tsis txhob nqus rau hauv lub nruas thiab ua rau cov khaub ncaws tsis zoo.
6. Tsis tu ncua tshem tawm cov khoom txawv teb chaws ntawm paj rwb residue ntawm qhov ntsuas kub. Thaum qhov sib txawv ntawm qhov ntsuas kub ntawm qhov ntsuas kub thiab qhov ntsuas kub tau pom tias loj dhau, nws feem ntau yog li 5 degrees. paj rwb.
7. Lub sij hawm teeb tsa" cua txias" timer feem ntau yog hais txog 1/4 ntawm lub sijhawm ntawm" cua kub" sijhawm.
8. Roj yuav tsum tau ntxiv rau lub rooj zaum bearing txhua lub hlis kom ntseeg tau tias cov kabmob ib txwm muaj lubricated.
9. Cov kav dej thiab lub luj tshib yuav tsum tau ntxuav ib hlis ib zaug. Yog tias lawv tsis tau ntxuav hauv lub sijhawm, lub sijhawm ziab yuav ua rau lub sijhawm ntev, uas yuav ua rau hluav taws kub hnyiab vim cov paj rwb wool ntau dhau.
