Cov ntsia hlau ob sab zoo
Cov ntaub ntawv tseem ceeb thiab cov yam ntxwv
Khoom siv:45 # hlau (qib 8.8), 40Cr hlau alloy (qib 10.9).
Nta:
Lub zog tensile siab: 10.9 qib bolts muaj lub zog tensile ntawm ≥1040MPa, haum rau cov khoom hnyav;
Tsis muaj kev pheej hmoo ntawm hydrogen embrittlement: kev kho blackening zam electroplating hydrogen embrittlement, tsim rau cov khoom siv precision;
Kev Kho Kom Haum: Qhov ntev ntawm lub teeb nruab nrab tuaj yeem hloov kho kom tau raws li qhov xav tau sib txawv.
Cov Haujlwm thiab cov xwm txheej siv tau
Cov Haujlwm:
Txuas cov thawv ntim phab ntsa tuab, cov flanges thiab lwm yam uas tsis tuaj yeem siv cov ntsia hlau ib lub taub hau;
Hloov cov vuam kom yooj yim disassembly thiab txij nkawm.
Xwm txheej:
Cov khoom siv tshuaj lom neeg (reactor flange), cov tshuab mining (crusher bearing seat), cov khoom siv fais fab (transformer bushing).
Kev teeb tsa thiab kev saib xyuas
Kev Teeb Tsa:
Ib kawg yog ntsia hlau rau hauv qhov threaded ntawm qhov kawg ruaj khov, thiab lwm qhov kawg yog nruj nrog lub txiv ntoo;
Siv cov ntaub thaiv tiaj tus + cov ntaub thaiv caij nplooj ntoos hlav kom txhim kho kev ua haujlwm tiv thaiv kev xoob.
Kev Txij Nkawm:
Xyuas kom cov txiv ntoo nruj tsis tu ncua, thiab rov ua kom nruj dua hauv qhov chaw kub siab (> 200 ℃);
Tsis txhob muab cov ntsia hlau dub tso rau hauv dej ntev kom tiv thaiv kev puas tsuaj rau cov yeeb yaj kiab oxide.
