Xinfa vuam cov cuab yeej muaj cov yam ntxwv zoo thiab tus nqi qis. Yog xav paub ntxiv, thov mus saib:Vuam & txiav Manufacturers - Tuam Tshoj Vuam & Txiav Hoobkas & lwm tus neeg (xinfatools.com)
Cov yam ntxwv uas cuam tshuam rau kev ruaj ntseg ntawm vuam arc feem ntau suav nrog cov hauv qab no:
(1) Welder kev khiav hauj lwm kev txawj ntse thiab tsis siv neeg arc ntev hloov peev xwm
Cov txheej txheem kev ua haujlwm ntawm welder yog qhov tseem ceeb hauv kev txiav txim siab arc stability. Thaum lub sij hawm qhov tseeb welding txheej txheem, tus welder rab phom (strip) gestures yuav tsum tsim nyog thiab lub arc ntev yuav tsum tau khaws cia kom ntau li ntau tau. Txwv tsis pub, welding tam sim no hloov pauv lossis txawm tias arc cuam tshuam yuav tshwm sim. Lub kaum sab xis ntawm lub vuam hlau thiab cov khoom ua haujlwm, thiab nruab nrab ntawm cov phom vuam thiab cov khoom ua haujlwm, yuav tsum tsim nyog los tsim kom zoo, tiv thaiv vuam tsis xws luag, thiab tuav lub pas dej ua ke. Rau kev vuam tsis siv neeg, qhov ntev arc yuav tsum tau hloov kho kom ntseeg tau tias qhov ntev arc tseem nyob tas li thaum lub sijhawm vuam, yog li ua kom cov vuam tsis tu ncua.
(2) Arc vuam fais fab mov
① Hom arc vuam fais fab qhov chaw: DC arc vuam fais fab qhov chaw thiab square yoj AC arc vuam fais fab chaw muaj zoo arc stability dua sine yoj AC arc vuam fais fab chaw. Kev ruaj ntseg ntawm pulse arc vuam fais fab mov yog zoo dua, yog li ntawd, pulse arc vuam fais fab mov feem ntau yog siv thaum vuam nrog me me tam sim no.
② Cov yam ntxwv sab nrauv ntawm arc vuam fais fab mov Cov yam ntxwv sab nraud ntawm cov khoom siv hluav taws xob yuav tsum ua raws li qhov xav tau ntawm arc ruaj khov combustion ntawm cov txheej txheem vuam sib txuas. Gas hlau arc vuam feem ntau yog siv nyias hlau (txoj kab uas hla ntawm cov hlau tsis ntau tshaj 3.2 hli), thiab ib tug qeeb-down yam ntxwv lwm yam hwj huam mov yuav tsum tau xaiv, txwv tsis pub cov welding Gas hlau arc vuam nrog unstable arc thiab siab tam sim no tej zaum. kuj siv cov hlau tuab. Thaum siv cov hlau tuab, nws yog ib qho tsim nyog yuav tsum tau siv lub zog hluav taws xob uas muaj cov yam ntxwv ntawm sab nraud.
③ Cov yam ntxwv zoo ntawm cov khoom siv hluav taws xob suav nrog kev hloov pauv luv luv. Lub CO2 vuam arc ncua sij hawm kub hnyiab thiab extinguishes. Qhov no yuav tsum tsis muaj-load voltage ntawm lub hwj huam mov kom nce sai thiab luv-circuit tam sim no kom nce nruab nrab.
④ Qhov tsis muaj-load voltage ntawm arc vuam fais fab mov. Qhov siab dua qhov tsis muaj qhov hluav taws xob ntawm arc vuam fais fab mov, qhov yooj yim dua nws yog pib lub arc thiab qhov zoo dua qhov ruaj khov ntawm arc combustion. Txawm li cas los xij, thaum tsis muaj qhov hluav taws xob tsis muaj hluav taws xob siab dhau, nws ua rau muaj kev phom sij rau tus kheej kev nyab xeeb ntawm tus welder.
(3) Vuam tam sim no
Qhov ntau dua qhov vuam tam sim no, qhov kub ntawm qhov arc siab dua, qhov muaj zog ntawm cov roj ionization thiab cov cua sov emission nyob rau hauv arc kem cheeb tsam, thiab qhov ruaj khov arc combustion yuav ntau dua.
(4) Arc voltage
Lub arc voltage yuav tsum zoo sib xws rau cov vuam tam sim no. Raws li qhov vuam tam sim no nce, lub arc voltage yuav tsum nce. Thaum lub vuam tam sim no tsis tu ncua, yog tias qhov hluav taws xob arc tsawg dhau, nws yooj yim ua rau luv luv; Yog hais tias lub arc voltage loj dhau lawm, lub arc yuav viav vias hnyav thiab rhuav tshem qhov ruaj khov ntawm vuam arc.
(5) Workpiece nto mob, huab cua khiav thiab sib nqus deflection
Yog tias qhov chaw ntawm lub workpiece tsis huv, xws li roj, xeb, noo noo, thiab lwm yam, arc ignition thiab arc burning yuav tsis ruaj khov. Thaum cov huab cua tiv thaiv tsis ruaj khov los yog muaj qhov sib nqus deflection, lub arc kuj yuav tsis ruaj khov.
