19. Cov teeb meem twg yuav tshwm sim hauv kev tsim cov siab - zaus welded round round? Yuav daws nws li cas?

19.1. Vuam cov teeb meem zoo
19.1.1. Nrib pleb ntawm Weld Jointial:
Cov teeb meem: Kev ntxhov siab ntawm kev sib koom ua ke welded lossis tsis zoo vuam zoo, xws li welding vuam tshav kub, mismatch vuam tshav kub, thiab lwm yam.
Kev daws: Txhim kho cov qauv ntawm Welded, tswj lub vuam txheej txheem, tswj lub vuam tshav kub, preheat cov pob qij txha welded, thiab lwm yam.
19.1.2. Weld suav nrog:
Cause: Thaum lub sij hawm ua vuam, hlau oxides lossis lwm yam impurities tsis raug tshem tawm thiab raug daig hauv Weld.
Kev daws: kho cov cuab yeej vuam kom ntseeg tau tias cov hlau molten thiab oxides tuaj yeem raug tso tawm tau zoo; Nquag tshuaj xyuas thiab khaws cov cuab yeej siv los xyuas kom muaj kev huv chaw vuam.
19.1.3. Tsis txaus fusion:
Cause: Tsis txaus siv tshuab hluav taws xob kub ceev lossis nrawm nrawm vuam ceev, ua rau hauv Weld tsis tau ua tiav.
Kev daws: Ua kom lub vuam cua sov ntxiv, txo cov vuam root, thiab xyuas kom meej tias kev ua tau zoo.
19.1.4. Khoom sib xws:
Yog vim li cas: Thaum lub sij hawm vuam siv, cov roj tsis yog kiag li tawm, thiab cov foos uas muaj txoj cai pores hauv Weld.
Kev daws: Txhim kho cov vuam ncig kom ntseeg tau tias cov roj yuav raug tso tawm kom yooj yim; Kho cov ntawv vuam vuam kom txo tau cov roj ntau tiam.
19.1.5. Lap Vuam:
Vim li cas: Kev siv misalignment ua los ntawm ob lub raj ntawm cov ntaub pua yeeb nkab muab cov menyuam yaus, kev puas tsuaj rau cov kabmob ntawm cov menyuam yaus lossis kev sib tw ntawm extrusion quab yuam.
Kev daws: Tshawb xyuas thiab kho cov chaw thiab cov xwm txheej ntawm cov kabmob extrusion, xaiv cov hom uas tsim nyog thiab yob cov nyiaj khaws cia, thiab lwm yam.
19.2. Cov khoom siv tsis muaj teeb meem
19.2.1. Lub Cev Muaj Zog Ua Haujlwm:
Cov laj thawj: lub cev muaj zog sib tshooj, overheating lossis laus, thiab lwm yam.
Kev daws: Yuav tsis saib xyuas cov xwm txheej ntawm lub cev muaj zog thiab hloov cov khoom siv uas puas lawm hauv lub sijhawm; Nco ntsoov tias lub cev muaj zog thauj khoom yog nyob hauv ib qho kev muaj.
19.2.2. Mechanical Cheebtsam Hnav:
Cause: Ntev - kev ua haujlwm ntawm cov cuab yeej ua rau hnav thiab kua muag ntawm cov tshuab kho tshuab.
Kev daws: Tsis tu ncua hloov cov khoom hnav thiab cov cuab yeej tu thiab txij nkawm; Teem cov phiaj xwm ntau lawm qhuav kom tsis txhob muaj cov khoom siv sib tshooj.
19.2.3.3. Roj Txhuas Tsis Ua Haujlwm:
Cov Teeb Meem: Clogged Roj Twj, Roj TakePage los yog nqus lub cev puas tsuaj, thiab lwm yam.
Kev daws: Txheeb xyuas cov xwm txheej ntawm cov roj twj tsis tu ncua thiab ntxuav cov kev thaiv hauv lub sijhawm; Hloov lub cev puas los yog ntim.
19.3. Txheej Txheem Tswj Cov Teeb Meem
19.3.1. Cov tsis raug hluav taws xob vuam teeb:
Vim li cas: lub vuam tam sim no, voltage, ceev thiab lwm yam tsis tsim nyog.
Kev daws: Raws li cov ntaub ntawv vuam thiab cov kev qhia tshwj xeeb, cov vuam vuam yuav tsum teeb tsa tsim nyog; Nquag ntsuas thiab soj ntsuam cov khoom siv vuam kom paub meej tias qhov tsis raug.
19.3.2. Tsis raug cai ntawm induction chev thiab impedo:
Cause: Txoj haujlwm ntawm lub nplhaib sib tham thiab kev cuam tshuam yog tawm ntawm txoj haujlwm zoo, cuam tshuam rau kev ua haujlwm vuam.
Kev daws: kho qhov chaw ntawm induction chev thiab impedance los ua nws nyob rau hauv qhov kev mob zoo tshaj plaws; Nquag tshuaj xyuas thiab khaws cov cuab yeej siv los xyuas kom meej txoj haujlwm ruaj khov.
19.3.3. Cov Teeb Meem Raw:
Cov laj thawj: cov khoom siv tshuab tsis khov ntawm cov khoom siv hlau, nplaim degroms lossis cov kev sib txawv hauv cov qhov ntev ntev, thiab lwm yam.
Kev daws: Xaiv cov ntaub ntawv rawize cov khoom siv thiab lub zog raw khoom siv khoom siv raw thiab kev txais; Rov qab thiab pauv hloov cov ntaub ntawv raw.
