Kev kho ntawm vuam tam sim no

 

Kev cuam tshuam ntawm cov khoom siv
Rau nyias daim hlau ntawm cov ntaub ntawv sib txawv, kev hloov kho ntawm vuam tam sim no yog raws li lawv cov ntsiab lus melting thiab thermal conductivity. Siv cov hlau nplaum nyias nyias thiab NV F420 steel daim hlau ua piv txwv. Cov aluminium alloy muaj qhov taw tes qis qis (kwv yees li 660 degree) thiab cov thermal conductivity siab, yog li cov cua sov hloov mus sai. Thaum welding aluminium alloy nyias daim hlau, yuav tsum muaj qhov loj dua vuam tam sim no los xyuas kom muaj cov cua sov txaus kom cov hlau hauv paus tuaj yeem yaj tag nrho. Nyob rau hauv sib piv, NV F420 steel phaj muaj ib tug ntau dua melting point (txog 1400 - 1500 degree) thiab kuj qis thermal conductivity, yog li qhov yuav tsum tau vuam tam sim no kuj me me. Piv txwv li, thaum welding ib tug 3 - hli - tuab aluminium alloy nyias phaj, qhov vuam tam sim no yuav tsum ncav cuag 180 - 220A; Thaum rau vuam NV F420 steel phaj ntawm tib lub thickness, qhov vuam tam sim no tuaj yeem nyob nruab nrab ntawm 80 - 120A.

 

Kev sib raug zoo nrog Thickness
Lub thickness ntawm nyias phaj yog zoo correlated nrog vuam tam sim no. Raws li lub thickness ntawm cov phaj nyias nce, yuav tsum muaj cua sov ntau dua los yaj lub hauv paus hlau, yog li cov vuam tam sim no yuav tsum tau nce ntxiv. Feem ntau hais lus, rau txhua txhua 1 - hli nce nyob rau hauv lub thickness ntawm nyias phaj, vuam tam sim no yuav tsum tau nce los ntawm 30 - 50A. Piv txwv li, rau NV F420 steel phaj nrog lub thickness nce ntawm 2 hli mus rau 4 hli, qhov vuam tam sim no tuaj yeem hloov kho ntawm 60 - 100A txog 120 - 180A. Nyob rau tib lub sijhawm, qhov kev pheej hmoo ntawm kev kub hnyiab - dhau ntawm cov phaj nyias yuav tsum tau txiav txim siab, thiab tam sim no tsis tuaj yeem nce ntxiv yam tsis muaj kev txwv. Nws tseem yog ib qho tsim nyog yuav tsum tau ua kom tiav kev hloov kho nrog rau lwm yam tsis xws li vuam ceev.

 

Kev kho ntawm Vuam Voltage

 

Yam khoom
Thaum vuam nyias daim hlau ntawm cov ntaub ntawv sib txawv, vim qhov sib txawv ntawm lawv lub cev thiab tshuaj lom neeg, qhov yuav tsum tau muaj rau vuam voltage kuj txawv. Piv txwv li, stainless - steel nyias phaj muaj ib tug tuab oxide zaj duab xis rau ntawm nws nto. Thaum lub sij hawm vuam txheej txheem, qhov hluav taws xob yuav tsum tau ua kom tsim nyog los xyuas kom meej tias cov arc tuaj yeem nkag mus rau hauv cov yeeb yaj kiab oxide zoo thiab ua kom cov vuam sib txuas zoo nrog lub hauv paus hlau. Rau cov pa roj carbon - steel nyias daim hlau, qhov yuav tsum tau muaj qhov hluav taws xob tsawg. Siv cov vuam ntawm 3 - hli - tuab stainless - steel thiab carbon - steel nyias daim hlau ua piv txwv. Lub vuam hluav taws xob ntawm stainless - steel nyias phaj yuav tsum nyob nruab nrab ntawm 20 - 24V, thaum cov pa roj carbon - steel nyias phaj tuaj yeem nyob nruab nrab ntawm 18 - 22V.

 

Thickness Kev txiav txim siab
Lub thickness ntawm nyias phaj kuj muaj qee yam cuam tshuam rau qhov vuam voltage. Thaum vuam cov phaj tuab tuab, txhawm rau kom muaj qhov ruaj khov arc ntev thiab txaus nkag mus, qhov vuam voltage feem ntau yuav tsum tau nce kom tsim nyog. Feem ntau, rau txhua qhov 1 - hli nce hauv thickness, qhov vuam voltage tuaj yeem nce los ntawm 1 - 2V. Txawm li cas los xij, yog tias qhov hluav taws xob siab dhau lawm, lub arc yuav ntev dhau lawm thiab qhov pores thiab lwm yam tsis xws luag yuav tshwm sim. Yog li ntawd, thaum kho qhov vuam voltage, nws yog ib qho tsim nyog yuav tau ua kom zoo - tuning nyob rau hauv ib tug haum ntau yam raws li qhov tseeb thickness thiab cov khoom yam ntxwv ntawm lub nyias phaj. Piv txwv li, thaum welding ib tug 5 - hli - tuab nyias phaj, piv nrog ib tug 3 - hli - tuab nyias phaj, lub vuam voltage yuav tsim nyog nce los ntawm 2 - 4V.
