Ua ntej pib ntawm txhua qhov kev ua haujlwm, tshuaj xyuas cov saw nro, xyuas kom meej tias cov hlua txuas txuas ruaj ntseg, thiab xyuas seb muaj suab nrov txawv txav lossis cuam tshuam. Thaum lub sijhawm ua haujlwm, saib xyuas cov saw hlau khiav txhua ob teev; Yog tias pom muaj qhov tsis txaus ntseeg, nres lub tshuab tam sim ntawd. Txhua hnub, ntxuav cov roj nplua nuj thiab hmoov av los ntawm cov saw hlau; txhua lub lim tiam, ntxuav cov saw nrog kerosene thiab siv cov roj tshwj xeeb los tiv thaiv kev sib txhuam qhuav.
Kev tshuaj xyuas lub sijhawm: Txhua hli, ntsuas cov saw txuas txoj kab uas hla coj (tso cai hnav tsawg dua lossis sib npaug li 10% ntawm qhov qub) thiab lub suab elongation (tso cai elongation Tsawg dua lossis sib npaug li 3%). Txhua peb lub hlis, ua qhov kev tshuaj xyuas tsis yog- puas tsuaj npog tag nrho cov saw txuas welds thiab siab - thaj chaw muaj kev ntxhov siab. Txhua rau lub hlis, tso cai rau ib tus neeg thib peb los ua qhov kev sim ua piv txwv rau kev sib tsoo (sampling ratio Ntau dua lossis sib npaug li 5%). Txhua xyoo, ua tiav kev tshem tawm xeb thiab tiv thaiv- kev kho corrosion ntawm tag nrho cov saw; rau kev ua haujlwm hauv cov av ntub dej, yuav tsum muaj zinc plating ntxiv lossis chrome plating tiv thaiv.
Yuav tsum tau Scrapping: Cov saw hlau yuav tsum tau muab pov tseg tam sim ntawd nyob rau hauv ib qho ntawm cov hauv qab no: saw txuas txoj kab uas hla hnav tshaj 10%, pitch elongation tshaj 3%, cov saw txuas nthuav tawm cov kab nrib pleb lossis cov yas deformation, welds yog tawg, lossis cov khoom tawg poob qis dua tus nqi tus qauv. Cov saw saw hlau yuav tsum tau cim kom meej meej thiab khaws cia rau hauv qhov chaw nruab nrab uas tau xaiv.
