Los ntawm txhais tes arc vuam: kev faib tawm, daim ntawv thov, tshwj xeeb tshaj yog

Los ntawm txhais tes arc vuam nrog coated electrodes yog ib tug txheej txheem, qhov tseem ceeb ntawm tshav kub uas ua raws li ib tug hluav taws xob arc. ignition allocates ib tug tseem ceeb npaum li cas ntawm tshav kub, ua nyob rau hauv lub ceev ceev melting ntawm lub ntsiab qhov chaw thiab lub vuam khoom - electrode.

Feeb Vuam Circuit Court muaj ob peb yam yooj yim cov yam ntxwv hais: ib lub hwj chim qhov twg los, vuam cable thiab ib tug hauv av cable, raws li zoo raws li ib tug tshwj xeeb clamp thiab electrode yas dhos.

Lub hwj chim mov yog yuav tsum tau mus muab qhov yuav tsum tau tam sim no rau cov ignition thiab kev tswj cov arcing txheej txheem. Los ntawm txhais tes arc vuam yog feem ntau powered los ntawm ib tug DC qhov chaw. Qhov no txhais tau tias cov mov tam sim no yuav tsum tau tas li txawm tias thaum lub electrode yog coj tuaj rau lub welded qhov chaw. Qhov no yog xam tias yog ib qho loj uas yuav tsum tau rau lub hwj huam mov.

Kom tsis tu ncua tam sim no thoob plaws hauv lub vuam txoj kev ncaj qha muaj feem xyuam rau lub arc stability, li no simplifying lub chaw ua hauj lwm uas txawj welder. Lwm feature raws li uas tus vuam apparatus yog dej num, - ib tug ntaus ntawv uas regulates qhov ntau ntawm cov vuam tam sim no. Nws yuav ua tau hluav taws xob los yog cov neeg kho tshuab. Hauv hloov, nyob rau hauv lem, yog muab faib rau cov inverter thiab thyristor, ib tug txhua yam yuav sawv cev los ntawm lub saturation inductors los yog sib nqus shunt.

Nyob ntawm seb lub hom ntawm cov zis tam sim no yog cais ob lub ntsiab pawg ntawm pab kiag li lawm: AC thiab DC.

Qhov chaw ntawm AC yog siv rau cov electro welding. DC yog siv rau lub hwj chim inverter thiab thyristor pab kiag li lawm.

Los ntawm txhais tes arc vuam ntawm ib qhov tam sim no yog muab faib los ntawm cov qauv ntawm cov txuas tus ncej mus rau lub compound rau pem hauv ntej thiab rov qab polarity.

Electrode yas dhos ua haum yooj yim tab sis tseem ceeb muaj nuj nqi - tuas cov electrode thaum muab cov kev kawm hluav taws xob sib cuag. Nyob rau hauv tas li ntawd, lub yas dhos tiv thaiv lub welder los ntawm qhov kev txiav txim ntawm lub fais tam sim no.

Los ntawm txhais tes arc vuam yuav nqa tawm nrog tshwj xeeb coated electrodes. Tej electrodes tub ntxhais cov ntaub ntawv uas yog leej twg txawv coatings. Qhov no yog los tiv thaiv cov weld pas dej ua ke, raws li zoo raws li mus rau stabilize qhov arc.

Cables thiab clamps lub vuam txoj kev siv rau ntws tam sim no nyob rau hauv cov ua hauj lwm thiab kev tiv thaiv kab.

Tsis tas li ntawd, tsis txhob dispense nrog lub koom haum pab "cov khoom" (pab kiag li lawm uas tiv thaiv lub adhesion ntawm kev ua tau zoo kub tiv cav tseb thiab arc afterburner). Lub ntsiab hauj lwm ntawm xws li yog mus piv rau lub lag luam ntawm cov tsheb.

Raws li twb tau hais, phau ntawv arc vuam yuav nqa tawm siv electrodes nrog ib tug tshwj xeeb txheej (thiaj li hu ua daubing). Cov yav tas ua hauj lwm pab tiv thaiv rau cov leeg welded Cheebtsam ntawm interacting nrog cov huab cua purification ntsiab khoom thiab nws cov Cheebtsam.

Nyob rau hauv lub manifold 4 yog cais electrodes ntsiab pawg. Lawv daim ntawv teev - rau hauv qab no.

1. Ib tug acidic txheej.
2. Rutile txheej.
3. Cov cellulose txheej.
4. Lub puag lub tsho tiv no.

Los ntawm txhais tes arc vuam yog ua los ntawm txhua tus ntawm cov hom electrodes, muaj cov yam ntxwv ntawm daim ntawv thov, uas pab kom cov tub txawg los mus xaiv tus zoo tshaj plaws kev xaiv rau ib tug lub hom phiaj.
